Master Lock 1530DCM Laminated Steel Combination Lock

Product Description

The MASTER LOCK 1530DCM is a laminated steel combination lock designed for portable security applications across residential, commercial, and light industrial settings. The body measures 1-7/8 inches wide with a double-armored stainless steel construction and an aluminum cover finished in a hot metallic anodized coating for corrosion resistance. The hardened steel shackle has a 9/32-inch diameter with 3/4-inch vertical clearance and 13/16-inch horizontal clearance. A smooth 3-number dial provides keyless entry without requiring a key or tool to operate. Internal working parts are rust-resistant and permanently lubricated, reducing maintenance requirements over the lock's service life.

This combination lock is suited for use on lockers, storage units, gates, toolboxes, and similar applications where a keyed padlock is not preferred. The keyless design is practical in environments where technicians, maintenance staff, or facility personnel need shared access without key duplication. The anodized aluminum cover provides additional resistance to the elements, making this lock a practical option for both indoor and covered outdoor installations.
