Combination lock is designed to open with directional movement instead of a number combination. You can open one-handed without looking using the directional combination of your choice, moving it left, right, up and/or down. Combination can be reset to any number of movements in any sequence. Combination lock includes matching passcode indicators (letters, numbers, colors, shapes, symbols) for added customization. Simply apply over arrows. Design includes 2" (51mm) wide metal body, anti-shim technology for maximum security, and hardened steel shackle for increased bolt cutter protection.
