The design is good and the product looks like it will do the job well. The modular design is useful as you can adjust it for your needs/shed etc.

My main problem is that the shear nuts won't shear. The cause seems to be is that these nuts are designed for clamping over metal and not soft wood as used on most sheds. What results is that the connection will crush the wood long before the nut shears. As mentioned in other comments this can be addressed by taking a hacksaw to the nut but this is additional installation and not really ideal. I feel that a spreader bar or large plate washer on the outside may help combat this but this is not included. It was also supplied with 8 nuts&bolts where you need 11 to install with all holes bolted. I had spares that I've used but would prefer to get enough supplied to fit it fully

[Pragmasis Comment: The shear nuts are normally fine but it does depend on the quality of the cladding on the outside of the shed. I'd guess that at least 95% are fine, but the instructions do suggest weakening the nut with a hacksaw, as you've said, if the wood isn't up to it. A spreader bar wouldn't work because many sheds have feather-edge boards, which don't present a flat surface on the outside, and large washers would also not work in that case, as well as compromising the grip that the square section under the coach bolt head provides into the wood, so the whole bolt would be liable to spin when being tightened. You only need 7 or 8 bolts to fit the Shed Shackle sufficiently. There are more holes in the metalwork to give more versatility for how you fit it, but it is not necessary to put bolts through every hole to get it secure. That would just make for more holes in the woodwork for no benefit. The instructions do explain this, with the particular note that the main 'shackle' section should always be bolted through all 4 of its holes. I hope that explains further. We are happy to answer queries.]

Great product, easy to install and definitely adds a lot of security to wooden sheds. Customer support is amazing from these guys and they are super helpful.

As the title says, they are not invincible unfortunately but made it very difficult for thieves to steal my bike, which allowed me to hear them and call police. It was too late and they had done the hard work with some very large bolt croppers and dragged my bike away anyway, chain still attached. Like many people have told me, if thieves really want something, they take it come what may. I'm glad the extra security bought me time but it didn't prevent them in the end.

Following this, I contacted the guys here and they have been nothing but sympathetic and helpful and are sending me a new centre section to replace, free of charge. Brilliant customer service.
[Pragmasis Comment: We are gutted, too. We hate our stuff being defeated, even when thieves are determined. We try to provide a big deterrent and to force thieves to bring tools and to take time so they don't get anything easily. Very sadly, it wasn't enough time for the Police to come this time. We are happy to replace the damaged section FoC and we always try to do our best to help, including when things go wrong. Sorry we weren't able to help you keep your bike this time. Let us know if you want to upgrade things to e.g. a concrete-mounted ground anchor such as the Torc Maxi as that can give better security if you are able to provide a concrete base for it to mount on?]

Great kit, delivered quickly, with good communication from Pragmasis. Easy to install, and looks secure. Just hoping it doesn't get tested (after my previous theft). I've added extra security measures to the garden and store in addition to the Shed Shackle.
Highly recommended.

I fitted my shackle today. Firstly I think the instructions make it seems more complex than what it really is. You need to simplify the guide as it made it more confusing. The shackle itself is made very well and I am really pleased - It was quite difficult tightening the two bolts nearest the shackle part due to the blobs there where its fixed to the steel strips. This is the only reason it lost a mark - It added masses of installation time. Getting it on the shed and all bolts loose took me about 20 minutes - Tightening them all until the nut heads sheared took 30 - A bit longer than it should have!

Overall I would definitely recommend it, it is an excellent product, but I am going to put in a floor shackle too just in case - A thief could just crowbar off the shackle from the shed and take the whole lot, if they were really determined.

[Pragmasis Comment: We've tried to trace this customer to get more information as nobody else has ever reported issues with the instructions or with the 'blobs' (rivet heads??) during installation. We also disagree with the comment about a crowbar as the product, when properly installed, has a side brace that is there expressly to stop crowbar and similar twisting attacks. The Shed Shackle is fixed in place with 8 bolts and we (and Sold Secure and the Police) don't consider a crowbar attack to be viable for a thief, especially when there is a bike in the way.]

I have a shed shackle and an 11mm chain with a closed shackle padlock to secure 3 bikes. I bought the shackle because I was worried about someone breaking into my shed which is hard to secure from the outside. My fears were realised when thieves attacked, however, due to fitting the shackle my three bikes inside were left untouched! They didn't even try to crop the shackle and just left empty handed! Really delighted with this product. It's easy to install and very well made. Thank you!

I've just fitted the shed shackle in my small shed. It was vey easy to fit. The printed instructions were clear, but had plenty of details for anyone who might encounter any problems with fitting it. Finally, what a great design - I now have a lot of confidence that my bike will be safe.

After 25 years storing my bicycles in a spare room I've been evicted to a timber shed, albeit a robust one, to make way for a home office. I added up the value of bikes: £20,000! One bike is worth £6000. So paranoia about security took over. Trawled the internet and Pragmasis clinched it because of the way they knew their stuff when I phoned for advice. Plus the reviews which give confidence. Amazingly thorough instructions included, even a drill and plastic bolt caps to protect the bikes. Very easy to install. I fitted 3 shed shackles over a whole wall and used 2 uncroppable 16mm chains, and a 13mm for a less valuable bike my wife uses (13mm is quite heavy enough for the "weaker" sex!). All chains 2.5m long which is a useful length to capture 2 wheels and frames on 2 bikes. The bikes cover the shed shackles making them hard to access and tamper with without spoiling the bikes.
Having finished the installation I am completely confident that this is the absolute best I can do to secure my bikes in a shed without a place for a Torc Ground Anchor. In fact, I think the deterrent is so great, a Torc Anchor isn't necessary in my case. I have peace of mind--the best indicator.

Thanks Steve,
Wonderful products, very helpful and informative staff, super fast delivery - why cannot all businesses be like Pragmasis?

this is my second purchase from securityforbikes.com, and I am delighted with the kit. I consider their products excellent value.

Shed shackle + chain package arrived very promptly. Chain and lock are good quality (bought a 4m chain to lock four bikes) and shed shackle was very easy to install (in my timber shed). Instructions were very comprehensive and clear. Much more confident about the security of my bikes. Recommended.

This was bought to fit in a shed being constructed, so it was designed into the build from the start. It has ended up being almost an integral part of the shed construction and is extremly secure - it would take a lot of effort (and a great deal of damage) to remove it. (Hopefully I will never find out).

Excellent shed shackle. Really pleased with it. Fits really well into the shed, extremely secure and resolves the issue of how to insert a ground anchor in. Much better alternative for a shed. I also received fantastic service: David got back to me really quickly to my questions and gave excellent advice. Delivered really quickly too. Overall, very happy.

Having accumulated a number of half decent bikes I needed some proper security in the shed. A ground anchor wouldn't work and the shed shackle has provided the ultimate solution.

Idiot proof to install due to the great instructions and the brilliantly supplied drill bit. My only problem was with the shear nuts as the fabric of my shed appears to be weaker than the force required to shear the nuts so I will need to hacksaw them - no biggy !

To be honest even leaving them on it would take a thief way too long be bothered either removing the shackle or trying to cut through the heavy duty cabling that goes through it.

Service was incredibly fast an efficient - I'm a very happy customer !

Cheers

Craig

This is a fantastic product and so easy to fit. I'm awful with DIY and managed to fit it with no troubles within 30 minutes. It's very strong and can't see anyone getting to my bikes now. Would highly recommend.

Fitted two of these in our new wooden shed to secure three bikes but also make it easier to get them in and out. My regular commuting (pre COVID!) bike hangs from a Decathlon wall hanger and secured with a heavy duty chain through the shed shackle. I like the fact the shackle is off the floor, making it easier to lock and unlock. The other shackle secures two bikes, fitted under the window as per the very detailed and helpful instructions (e.g. about the sound of the glass creaking!). Impressed.

Fairly easy to fit and seems very robust and secure. Choose your position carefully. Shear nuts work quite well but beware possible damage to outside of the shed when tightening
[Pragmasis Comment: Tightening the shear nuts can sometimes cause the bolt heads to pull into the wooden cladding on the outside of the shed. If that is a concern, we suggest in the instructions that you can use a hacksaw to weaken underneath the hexagonal head of the shear nut, so it shears-off more easily. Usually, it is not a worry. I hope that helps.]

Very impressed indeed with the quality and attention to detail. The instructions are exemplary with every eventuality covered.
Simple to fit, even came with the drill bit required for drilling the mounting holes and plastic caps to cover the ends of the bolt threads.
Very pleased indeed and would not hesitate to recommend this excellent product.

The customer service was excellent and the shed shackle is superbly engineered - a valuable addition to shed security. Thanks!

Fitted the shackle in just a couple of hours, my shed was a little thin so I added a couple of extra sections of wood. The bolt lengths were spot on. Had a bit of trouble with the shear nuts, but persuaded them off with a chisel and a hammer.

Great customer service and prompt delivery, very easy to fit and nice touch that a drill bit was provided. Very good instructions and very simple to fit, It was installed and ready to us in 20 mins and now the 2 bikes are very secure in our shed. Thank you

Ordered 2 shed shackles and cen 4 padlocks for my chains. Communication was fantastic and delivered really quickly. The shed shackle was easy to install, I ordered longer bolts as unsure of the length, cut them off, no one is stealing my bikes!! Thanks for such great service

I'm very satisfied with this excellent product - does the job perfectly and added coach bolts onto hinges as suggested.
Customer service was exemplary - my thanks to David.

Had three mountain bikes stolen out of my shed recently. Am now beefing up security to Stalag Luft 3 proportions! Searched the internet and found the shed shackle. Wow....this thing is awesome. Simple, high quality British Engineering at it best. Was a doddle to fit (40 mins)and feels totally secure. Thief is going to have to take half the shed wall if they want to have another go. About to invest in the 13mm chain and lock to go with it.
As with other posts customer service has been outstanding.

This is an excellent product. Having fitted this to my previous shed I have repurchased for my new shed. It is easy to fit (1hr in this instance) and gives a good feeling of security for my bikes - I use with a pragmasis motorbike chain and lock.

Took a while to decide how to secure my bike but this works a treat - very easy to secure to the shed frame - bolts were perfect and the drill bit provided was v handy. Instructions about as good as I've ever seen for any product I've bought. Excellent!

Keeping my motorbike in my shed I was in need of an anchor to add extra security, but due to the layout I was unable/impractical to hack up the shed floor to access the concrete base.
The Shedshackle met all my requirements, and is an impressive heavy duty bit of kit.
It was relatively easy to install, although I did nearly cut off the tip of my finger using a hacksaw to trim the bolts down!(oops)
The shear nuts did prove quite difficult to detach, however, and needed to be encouraged with a hacksaw. I also think I overtightened the bolts trying to shear the nuts, as the bolt heads have sunk quite substantially into the outer wood panel. But that panel is not visible, so I'm not bothered.
Anyway, it's an excellent bit of kit, and feel it really provides a strong deterrent.

Brilliant product for a good price

after moving house and having to leave my Torc Ground Anchor firmly embedded in the garage in our old place, this time as I only had a wooden shed, albeit a good quality one from EasyShed, I went with the Shed Shackle.

Easy to fit, feels and looks secure, i imagine it would put any would be thief off even having a go!
I bought the package deal which included a 11mm chain and Squire padlock. Good value for peace of mind.
Highly recommended and the customer service is second to none.

I placed the order just before Christmas and it arrived the following morning - excellent service during a busy period. From opening the package of Shed Shackle, 11mm chain and lock it is obvious that it is a quality product. The well thought out Shed Shackle is modular and can easily be adapted to many situations. Fitting was very straightforward and took just over 30 mins. If you find, as I did, that the bolt digs in a bit too much into the wood before the shear nut fails, a couple of nicks with a junior hacksaw should do the trick.

Like many, I can't fit a ground anchor in my shed, so after a lot of research only one product was at the top of the list as the next best thing.
I'm not the best at DIY, however even for me, fitting it was a doddle. The drill bit is supplied, and the instructions were very clear.

Make sure you fit it in the correct place, as you won't get it off after it's fitted!
It feels very secure, but I hope it's never put to the test!!
