HIGH SECURITY: The long shackle code padlock provides 10,000 combinations with all wheels tightly fixed to make decoding impossible. 7mm-thick hardened steel shackle and high-strength zinc alloy body, are of high resistance to cutting and sawing. 12 mm of the hasp is locked inside the lock body while in use, far longer and securer than most combination locks in the market. It is a solid, heavy duty combination lock. EASY TO SET: The long padlock combination allows setting your own combination by simply flipping a "SET" switch at the bottom and back. The 4 number wheels are exposed front and back, making it much easier to turn, even with gloves on. Each dialing is designed to click into place with accuracy and suitable feeling for code aligning. EASY TO READ: Unlike code locks with shiny chrome dials, these long shackle locker padlocks come with a good contrast of bold white numbers on a black background, which is very easy to see even in places where there is no much lighting. It is very friendly for the senior and people who need reading glasses. ANTI-MISOPERATION DESIGN: Most combo locks on the market have their setting mechanism exposed outside, in which accidental code setting could happen randomly in daily use, when carried in a bag or someone plays with the locker padlock and make it useless. APPLICATION: The locking arm is 57mm when closed. Longer clasp gives more wiggle room, making it easy thread through to longer/thicker latches or chains. The long shank padlocks with code serve most household uses on a door latch, chain, toolbox, wardrobe, cupboard, closet, etc. And they are also good choices for gym lockers, school lockers, work lockers, anywhere you have storage and security need, and the like.
