Padlock GEKO G10912 brass combination padlock 21 mm shackle, 4-digit code

GEKO G10912 is a compact brass combination padlock with a 4-digit code and a 21 mm shackle diameter, designed for everyday security of small personal and utility items. The lock features a corrosion-resistant brass body that suits indoor and some outdoor applications, and a 4-digit mechanical code offering up to 10,000 combination possibilities for configurable, keyless access control. Its reduced size and simple mechanism make it practical for lockers, cabinets, suitcases and small storage boxes where moderate theft protection and easy operation are required.

Advantages

The brass construction provides natural corrosion resistance and durability while keeping the padlock lightweight. The 4-digit combination mechanism eliminates the need for keys and allows quick code changes for controlled access. A 21 mm shackle diameter balances compact dimensions with sufficient clearance for typical hasps, locker loops and zipper pulls. The mechanical code requires no batteries and operates reliably in everyday conditions.

How to use

Set an initial 4-digit code and scramble the dials to lock. To open, align the chosen 4-digit code and pull the shackle. To change the code, follow the manufacturer’s procedure: open the lock, rotate or press the reset mechanism (as indicated on the lock) and set the new 4-digit sequence, then return the reset to its locked position. Keep the chosen code documented in a secure place to avoid accidental lockouts.

Usage recommendations

For prolonged service life, avoid continuous exposure to heavy rain or salty environments; periodically clean the dials and lubricate the shackle pivot with a light, lock-compatible lubricant if stiffness occurs. Choose a non-obvious 4-digit code and change it periodically when used in shared spaces.
