Product Description

What It Is
A compact, high-security padlock made to work with 9/32" (7mm) square security chain. Its sleek design makes it easy to store, and means your entire security chain setup will be easy to pack along.

Why You Need It
Because a good security chain is only as good as the lock you secure it with. This lock's pins are completely shrouded and even protected by the security chain. Thieves look for the quick and easy target, but with this lock, there are no shortcuts! No bolt cutter access!

How Compact Is It?
Well, it weighs 0.72 lbs (325 g) and fits easily in the palm of your hand. It is actually small enough to thrown in your pocket or backpack. We know you will be impressed!

How Secure Is It?
This is a true, high-security padlock that was hand selected to work with 7mm chain. It has a fully armored brass body with tempered, copper, nickel, case-hardened and chrome plated steel armor. It also features independent and rotating lock-bolts, made of steel with pull-resistant programmed head breakage. Ball type locking mechanism, key retaining and with 5 pin pull-resistant plug. We know that's a lot of tech speak, but the point is that this is a true security lock. And because it's compact and "in line", your chain security package remains small, sleek, lightweight and ready for quick deployment. We picture this as the perfect security chain kit for bicycle, scooter and even motorcycle riders.

A perfect complement to my Pewag 9/32" chain. Expensive looking, small but mighty padlock used to lock up dog & kennel in the back of my pickup.

It fits Westech's 9/32" security chain perfectly, and it seems to be a sturdy, well-made lock.
