ULAC Bicycle Combination Chain Lock with 100 cm Length, 5 mm Steel Links, Resettable Four-Digit Dials and Fabric Sleeve for Cycling Storage Security

One-metre chain lock with four-digit combination

This ULAC lock uses a 100 cm steel chain, a woven sleeve and a resettable four-digit combination mechanism. Choose Black / Gray or Green / Orange. The flexible chain can be routed around compatible bicycle frames and suitable fixed objects, as illustrated. Each option supplies one lock.

Steel chain and sleeved construction

The detailed specification lists 5 mm internal steel-chain link diameter and 100 cm chain length. The lock body is zinc alloy with ABS combination dials. A woven sleeve covers the chain contact surface. The 5 mm figure refers to the internal steel link material rather than the overall fabric-covered width.

Keyless operation and personal code

Four numbered dials provide 10,000 possible four-digit combinations. The reset mechanism lets you set a personal code using the illustrated collar. There is no separate key supplied for the combination mechanism. Record your selected code and test opening and closing before using the lock on a bicycle.

Reset instructions

Align the current four-digit code with the guide mark and pull out the locking end; the illustrated initial code is 0000. Turn the reset collar to the right by one-quarter turn, select four digits and align them with the mark. Turn the collar back to the left to finish. The image code 1111 is an example, not a required setting.

Size, weight and use planning

The source lists approximately 560 g net weight. Check that the 100 cm chain reaches around the selected frame section and fixed anchor point before purchase. Keep the combination body accessible and choose a routing that allows the chain to close without forcing the mechanism.

Colors and included lock

Black / Gray has the pictured dark sleeve and gray lock body. Green / Orange has the green patterned sleeve and orange body. One selected ULAC chain lock is supplied; bicycles, posts, railings and other demonstration items are not included.
