The Squire SS100CS is the world's strongest padlock. This is the first ever padlock to achieve the highest LPCB Level SR4 accreditation in addition to CEN 6 formal approval. It passed at Sold Secure Diamond standard when tested with a 22mm security chain.
This closed-shackle padlock offers almost impenetrable resistance against common attack methods including grinding, cropping, freezing, and drilling.
Make no mistake, this is a massive lock. However it pairs well with the Protector 19mm chain.
Note that this is an exceptional padlock that uses two cylinders! It has two keys, and both must be inserted and turned in order for the lock to open. Each of the cylinders locks one side of the shackle. The shackle is removable when both cylinders are unlocked.

- Sold Secure Diamond (when used with a 22mm chain)
- 20mm hardened boron steel shackle
- Weighs 4.3kg

We recommend this padlock with the Protector 16mm, 19mm and 22mm chains.
