After several improvements we have achieved the following product properties:

• It is not only resistant to bolt croppers, but impervious to hand operated bolt croppers. 
• Trying to hacksaw it is useless
• Sledge hammer attacks are useless
• Freeze Attacks (another favourite method) are useless
• Flexibility – with the long link system you can secure any number of Immobiliser Chains with just one lock.

Series III has a 16mm diameter link, the Series IV has a 19mm diameter link, which are a visual deterrent, Mr Bike Thief probably won’t bother and will move on to an easier target

All Immobiliser Chains are triple tempered, BRITISH steel, enhanced with carbon, manganese and boron, case hardened with 3 separate processes and zinc plated

All Immobiliser Chains have a ductile core and extremely tough case hardening, this makes them impervious to hand held bolt croppers & also ensures that they can withstand brutal impacts

These are the “BEST SECURITY CHAINS” on the market, bar none. 

We have used the same high standards when choosing two suitable locks to use in conjunction with the Immobiliser series chains. We offer the Squire SS65CS Stronghold closed shackle padlock. It is Squire’s flagship lock. It is SEN rated 6, which is the highest rating you can get on a lock in Europe. It is handmade in BRITIAN and has a hardened Solid Steel Body, with a 12.5mm enclosed shackle. It is Sold Secure GOLD accredited and is virtually indestructible. We also offer the CISA 58550-67 lock - Sold Secure GOLD! It is a hardened solid steel body carrying a SEN rating of 4. It has a sacrificial end to the shackle which if tampered with, will come off to protect the shackle from the attack.

For the ultimate in security at home we recomend that you complete your security package and use your chain and lock combo in conjunction with a ground anchor. We have chosen the two ground anchors which we feel are made to the same exacting standards we use for our chains. These are the Rhino Defiant, which has a system of roller bearings which would just spin if the anchor is attacked with grinders. It is fixed into the ground with a chemical bolt. This bolt is a very secure fixing. We also recommend the Hardie Secure Ground Anchor, it is a flat anchor which is small, yet extremely robust & strong, it has a really attractive chrome finish. It is fixed using an expandable bolt and has a cap which covers the bolt. It swivels and is very easy to use. Both Anchors are Sold Secure GOLD.

We are always researching & developing our chains, to ensure that we give you the TOUGHEST SECURITY CHAIN available on the market.
