Contacted Steve B from Pragmasis regarding his security products, receive great advise and customer service.
Order 16mm 0.8m chain to accompany the 340mm anti-pinch pin, package was very quickly despatched and received the following day.
Bought as a security product to travel with me, yes collectively it's a tad heavy but good security products usually are.
I know I certainly won't worry with this beefy chain and pinch pin attached to my bike, rather that than some cheap thin tat.

I have purchased a 2m long 16mm chain which I am very pleased with. Good built quality, solid, strong. Excelent customer service! Very helpful people! Strongly reccommend the company and it's products.

bought this chain for sports club last year {2012}to secure mowers with torc u ground anchor after thieves stole mowers ,insurance company and police were delighted as they rate both chain and ground anchor,excellent products and service.

I have multiple chain locks, but after the latest attempt to relieve me of my collection of top end MTB bikes, decided to get the 16mm chain and lock combo. Order arrived within 24 hours and by the look of it this chain will be well worth it. Super quality

After using your brilliant 19mm chain I wanted another quality chain that was light enough for me to carry on the bike. Once again quick postage and another very good security device for when I am out and about.

Worried about security of your new bike. A solid 16mm minimum hard cased chain is the most useable option to leave out at your commute end. Mark the sleeve ends to recognise any tampering. Combined with a really good lock should give you peace of mind! The anti pinch pin combination makes it easier to feed through the engine and frame. Any 16/19mm kit from this company will give you a degree of confidence that it will be where you left it? Made in England wonderfully welded, no cheap Chinese manufacturing.
Can’t praise the correspondence and delivery for my order enough. Their extremely helpful, ten out of ten. Have a data tag and an Ingersoll 10 leaver lock on the front disc. Must be too much trouble to be worth stealing. Not going to stop the rider being jacked though. They want it they take it.

Just to write one small testimonial about this company and the product that I bought.
Simply perfect your delivery service.
Simply perfect the quality of this chain.

Thanks a lot :-) In future when I think about buying security for my motorcycle, I'll remember you for sure.
