Bought to secure double gates in the garden. Very heavy duty and does the job nicely. Unlike other similar items it comes with four keys

Bicycle chain just what I have been looking for. . My bicycle has very narrow spokes and its hard to get a solid chain through

Good chunky chain with a sturdy lock, long enough to chain my bike up securely. Nice to have the sleeve over the chain to protect my bike from scratches & the rain cover over the keyhole.

Safety chain

Hasn't been 'put to the test', but seems sturdy and does what I got it to do, securing a bike while it's stored in the shed.

A good solid piece of kit. A tad heavy, but that's a part of the deterrent factor: it would take a while and a lot of noise to get through this!

Bought after bike theft with an inferior cable lock. I used in combination with 27446 security cable to loop through the wheels

Much easier than a D-lock

This device shouts “security” from first glimpse. One thing I will warn, make sure you have some panier bags because that’s the safest way to store it when not in use.
