Brass Padlock with 4-Pin Cylinder

This Master Lock brass padlock uses a 4-pin cylinder and comes keyed alike to key number 505. The laminated brass body measures 1 3/4 inches wide and 7/8 inches thick. A hardened steel shackle provides 2 1/2 inches of vertical clearance and 3/4 inches of horizontal clearance. The lock is rated for weather resistance and high security.

Limits of a 4-Pin Keyed-Alike System

A four-pin cylinder offers fewer unique key combinations than higher-pin models, so it is not suited for installations that require a large master-key hierarchy. All locks in the same keyed-alike group open with the same key, which means any holder of key 505 can open every padlock in the set. The keyway is fixed to the Master K1 profile and the core cannot be rekeyed or swapped for an interchangeable core.

Check Shackle Fit and Key Management

Verify that the 5/16-inch shackle diameter and the 2 1/2-inch shackle height will pass through the hasp, chain link or staple you intend to secure. Confirm that a single key number 505 fits your access plan, because the lock cannot be rekeyed to a different code. The product carries California Proposition 65 warnings for chemicals known to cause cancer and reproductive harm.
