Prime-Line Mail Box Lock, Keyed, 5/16 in. Bolt, Brass Plated, MP4049

Replace a worn, damaged, or missing mailbox lock with this brass-plated replacement lock designed for use on Bommer mailboxes and other compatible older-style apartment mailbox applications. Constructed from durable steel, this lock features a heavy-duty 5/16 inch bolt throw and a 3/16 inch offset keyway to provide reliable mailbox security and proper latching performance. The key-retaining design allows the key to be removed only when the lock is in the locked position, helping prevent the mailbox from being left unsecured. Its brass-plated finish delivers a traditional appearance while helping resist everyday wear. Ideal for property maintenance professionals and DIY repairs, this replacement lock offers an economical solution for restoring mailbox functionality without replacing the entire mailbox. Before purchasing, compare the bolt throw, keyway offset, and overall lock dimensions to ensure proper fit and operation.
