Chain lock MASTER LOCK 90cm long x 10mm diameter hardened steel

The Master Lock 8234EURDPRO chain with mini U-lock is a 90 cm long security solution combining a 10 mm diameter hardened steel chain with a compact U-lock. The chain's hardened steel links and a nylon sleeve help protect the chain and the secured item from cutting, sawing and surface damage, while the mini U-lock adds an extra hardened-steel locking point with a corrosion-resistant finish.

Advantages

The 10 mm hardened steel links provide elevated resistance to cutting and sawing. The nylon sleeve prevents scratches to frames and equipment. The mini U-lock features a hardened steel body and a 14 mm hardened steel shackle for additional cutting and prying resistance. A high-security disc cylinder reduces the risk of picking and the dual locking levers improve resistance to prying and hammer attacks. The product is weather resistant and comes with a Limited Lifetime Warranty.

How to use

Thread the 90 cm chain through the frame and wheel or around the object to be secured, then pass the chain end into the mini U-lock and close the shackle. Ensure the nylon sleeve covers contact points to avoid scratching. Verify the disc cylinder engages fully and test the locking levers by tugging gently on the closed lock. Carry spare keys in a secure place or register the key code if offered by the manufacturer.

Usage recommendations

For best security, loop the chain through the bike frame and both wheels when possible and lock to an immovable object. Avoid leaving valuables unattended for long periods and store the lock dry when not in use to prolong life despite its weather-resistant design.
