Bought this to secure my new mountain bike as was looking for a high security wall anchor that could be removed if I move house in the future. Had just bought one of the security chains from Pragmasis and was really impressed with the quality so when I saw they also had a wall anchor that fitted the bill and that was designed to work with the chains it was a easy choice. The anchor feels robust to say the least, it's certainly heavy and feels very solidly made. It's reasonably straight forward to fit if you can operate a drill and once fitted in place with all the fastenings looks extremely secure. Am very impressed and happy to pay for quality to secure my bike. Service is also really good, items were delivered promptly with clear updates to confirm when posted and due to arrive.

Very clever design that uses the chain to hold a cover plate over the anchors securing bolts. Easy to install and a great option of you may need to move the anchor at some point.
I use this with the bolt cropper proof 16mm chain and round lock package deal to secure my mountain bike. Very happy to now have a proper security setup, thanks guys !!

I now have two of these and think they are great. My preference would be to have a ground anchor that folds down when not in use but I didn't want to put anything permanent in the locations I am using so this fits the bill perfectly. It is a clever setup for a ground anchor that seems as secure as possible yet completely removable.

I bought this Anchor in combination with 16mm chain 2,5m and SS65CS lock for my two offroad bikes. I really couldn't get any better as it was really easy to install and the 16mm diam. chain is still good enough to handle but pretty sure not for thief. Alarm has been installed as well so I have a good sleep now.

I recently took delivery from Pragmasis of a system of items for securing my motorcycle. The package comprised; 16mm Protector Chain, Double Doofer anchor, Squire SS65CS padlock and Anti-Pinch Pin. Everything is of excellent build quality, and the inclusion of bolts, drill bit (marked for depth) and hex (‘Allen’) key, hole clearing tube, and comprehensive and clear instructions made the installation so much easier.
The Double Doofer is a very clever and robust design, and once in situ (wall mounted) looks very tidy. The adjusting plates that it utilises means it is a very good fit for the chain, so it cannot be tampered with once the chain is fitted. It takes me seconds to secure the bike once in position, and it would take a pretty determined thief to get past the house alarm and then have to tackle the Pragmasis system.

I have recently moved home and need a secure anchor to secure my motorbike too.
I did have a Torc anchor at my previous house and was very impressed so Pragmasis was my first port of call to see what was on offer.
I wanted a removable anchor as my shed is full of asbestos so when that's removed and a new shed is built I can move the bike into it's new home and use a permanent anchor such as the excellent Torc pragmasis sell.
It was easy to fit, my top tip is to use a 10mm masonry drill bit to start off the holes as this size drill bit fits in the bolt holes of the bottom plate.
Once I fitted an extra adaptor plate my Almax series 3 chain fits perfectly and i can sleep safe in the knowledge that my bike is totally secure.
I highly recommended this, excellent bit of kit.
The cherry on the cake is that this will be very handy to secure my motorbike trailer and mountain bikes in the future.

Easy to DIY installation and peace of mind along with a 19mm chain.

Great product - easy to install and very solid looking. Bought together with a 19mm chain and a round lock and very pleased with them all!

I think this is a great design by Pragmasis to make a secure yet removable anchor. However, how does the chain through the anchor prevent a thief of loosening and removing the plates with a screw driver, and then allowing the leeway he needs to unscrew the underlying bolts? [Pragmasis Comment: The plates are a close fit under the inner bridge piece and are located by a recess in the side of each plate that engages with the inner bridge. Those plates are hardened steel and they can only be removed by lifting them. We say repeatedly that the whole design is only secure if there is a close-fitting chain locked through the whole assembly, and that close-fitting chain prevents any plates being lifted and thus removed. The screws have no impact on the security. They are just there to stop it all rattling. The security is achieved by the way the elements fit together in the design and by everything fundamentally being a close fit. I hope that clarifies? Thanks, Steve.]

Excellent instructions. They even went through the effort of taping the drill bit for you to mark the correct depth of the holes. Quality product. Bought with 19mm chain which is a good combo.

Bought with the 19mm chain and round lock this is a great piece of kit for anyone who does not want to permanently affix something to the wall or floor.

Supplied with everything you need to fit it apart from the drill, it took less than 10 min to install with an SDS drill, maybe a little longer with a normal hammer.

With the 19mm chain the top cover cannot move at all.

Very happy!

The only removable anchor on the market.
Very sturdy and easy to install.

That´s the words the thief will have in his mind when he first lays his eyes on this behemoth.

Bought it with the 19mm and roundlock and its just crazy how massive everything is.

Easy to fix and great that it comes with all the parts inc drill bit. 16mm chain going through it so used 1x riser plate. Very happy with it, thieves may not be. :)

This is my first purchase from this company and I am extremely impressed.

The delivery was amazing, using DPD I was kept up to date throughout and delivery was very quick.

Usually I buy the Oxford sold secure ground anchor but after 3 house moves and having to leave it behind each time I thought it was time for a change! This anchor is so easy to fit, all tools included (unlike the Oxford anchor) and one thing that really impressed me was that the tools supplied were all good quality and not any old cheap rubbish that breaks the first time you use it like some other kits.

The anchor feels very secure and I am very happy with the products. Given you get detailed instructions, quality tools and the well made secure anchor I think the price is very reasonable. Already recommending it to friends!

A very good quality easy to install ground anchor, so good I've just bought another!
It took me about 30 mins to install with all the tools supplied, you'll only need a drill and a couple of cups of tea to finish the job.
All in all a very clever design that will allow me to take the anchor with me if I ever move home, how clever is that?
I'll sleep well knowing my pride and joy is secured to the ground with this thing via a pragmasis chain and padlock - what a piece of security!

I bought this as I wanted a removable ground anchor which provided 5* protection. This certainly didn’t disappoint, very well made and strong in construction.
Fitting took 30 mins, the hardest part was drilling the concrete!!
Would definitely buy again.

We already have the Torc ground anchor fitted but needed a new one, as we are very happy with the Torc we came straight back to Security For Bikes. We are planning on moving in the next year so bought the Double Doofer. Fitting was no problem and the peace of mind its given us is well worth the money, it feels solid and robust. The service was excellent as well, very fast delivery and communication was brilliant as well. Highly recommended

I was surprised how heavy this anchor is, solid build and I ended mounting it to my wall since my floor was too weak .. solid and easy to mount!

Also great that it comes with everything you need, drill bit, screws, tools! Great !

I bought this Double Doofer knowing that I need to remove it in a year from now. The double shell design makes it a beast of an anchor and I sleep extremely well at night knowing the anchor is going nowhere. I used the extra SDS Plus bit with a hired SDS drill and had the fitting holes drilled in minutes. The supplied spacing plates work perfectly for smaller chains and now I have the Protector 19mm chain with no spacing plates. Make sure the ground area you're going to place it in is flat enough to include the second cover as well without any movement.

Setup: Squire SS65CS-XLN padlock / Protector 19mm chain / Double Doofer ground anchor

I have this anchor on my garage floor used with the Protector 19mm chain, securing 3 mountain bikes. I feel happy I have the best there is when leaving the house

I bought a Protector 19mm Chain and RoundLock combo and Double Doofer Removable Ground Anchor.

It is used to secure by moto in a shared open space garage and combo does its job quite well.

Item details in web site perfectly describe the product and the delivery service was excellent.

I would strongly recommend SecurityForBikes, if you are looking for top quality products and excel service.

Always a pleasure to deal with Pragmasis, dont scrimp on security, NOT made in China

Solid bit of kit - very well thought out.
Instructions couldn't be clearer - foolproof.
Expect this will be relocated several times - hopefully somewhere on the Costa Del Sol soon!

After much deliberating i decided to purchase this combo (also Round lock). Installation was straight forward but "read" the instructions if you've never fitted one before. The anchor oozes quality and inspires confidence in use. The Protector chain is top class also, a winning combination.

This is a solid, great product in use with one of their protector chains.

Instructions and bits provided couldn't have been better, well thought out.

Wouldn't hesitate to recommend this company.

I bought this with the 16mm chain and DIB-D lock to protect our new Orbit e-tandem and other cycles in the garage. The quality of each item is exceptional, and the instructions (together with the video advice on this site) are clear and sound. Fitting was straightforward and everything looks and feels really secure. We'll be moving home in a few years, so it's good to know this will come with us. The whole package is excellent value for money, given the cost of replacing the cycles. Based on these items, I thoroughly recommend Pragmasis' services.

Definitely happier having my bike chained to this anchor, using the anti-pinch pin. I am very happy with the product and would recommend it to anyone who is renting who may need to remove the anchor in future.

Instructions were extensive and easy to follow and when I had a question, it was answered right away. Customer service 10/10 (Thanks, David!). Delivery was super fast – this arrived before my Amazon Prime delivery, that about says it all!

I bought this together with the 16mm chain and and padlock and it's really, really good. We all know that a professional thief will steal you car or motorcycle if they really want it but this chain, lock and anchor combo will deter all but the most determined crooks! I mounted it on a wall of my house. Excellent service as well.

Secured to a wall, with two bikes attached. Great kit and instructions, right down to a piece of tape around the drill bit to indicate correct depth; couldn't have been easier to install.
