Commercial steel padlock with 2-1/2 inch shackle

This Master Lock commercial padlock uses a five-pin cylinder and a 2-1/2 inch hardened steel shackle. The rectangular steel body measures 1-3/4 inches wide by 7/8 inch thick. It is supplied keyed alike to the 10R41 key code on the Master K81 keyway.

Five-pin cylinder and long shackle constrain pick

The five-pin Master K81 keyway provides standard commercial pick resistance but does not meet high-security cylinder ratings. The 2-1/2 inch shackle clearance suits hasps or chain links that a standard shackle cannot reach, yet the 5/16 inch diameter may not fit tighter staple holes.

Replaces shorter-shackle

Choose this model when a 1-1/2 inch shackle cannot span the hardware or when multiple padlocks must share one key. It is not suited for exposed coastal or corrosive environments because the steel body and shackle lack a weather-resistant coating.

Questions about this item

Which shackle height should I choose for a hasp that needs 2-1/2 in clearance?

The 2-1/2 in shackle height is the long-shackle option in this listing and matches that clearance exactly.

What does the 5-pin cylinder mean for day-to-day security?

Five pins with the Master K81 keyway provide commercial-grade pick resistance and the lock is rated high security.

How does the keyed-alike system work with the 10R41 key code?

Every padlock in the set opens with the same 10R41 key so one key manages multiple locks.
