Mailbox lock with 5/16" bolt throw

This brass-plated steel lock secures standard mailboxes with a heavy-duty 5/16 inch bolt throw. It includes one lock cylinder and two keys cut to a unique keying. The key can only be removed when the bolt is in the locked position. It is designed as a direct replacement for Bommer-style boxes.

5/16 inch throw and 3/16" offset keyway

The 5/16 inch bolt throw provides solid engagement with the mailbox frame for everyday security. A 3/16 inch offset keyway aligns with common factory cutouts. The mechanism is built from steel with a bright brass finish for corrosion resistance. It does not suit boxes requiring a longer throw or a centred keyway.

Fits most existing mailboxes

Installation uses the existing mounting holes on compatible Bommer and similar metal mailboxes. No new drilling or specialised tools are required for a standard swap. The package supplies the lock body and two keys only; mounting hardware is reused from the original unit. It frees you from ordering a model-specific part from the original manufacturer.

Questions about this item

Will the 5/16 inch bolt throw reach the strike plate on my existing Bommer mailbox?

The lock is built to fit most existing mailboxes including Bommer models, and the 5/16 inch bolt throw matches the original hardware specification.

How can I confirm the 3/16 inch offset keyway aligns correctly after installation?

Insert the key and turn; it should rotate smoothly and only release when the bolt is fully extended into the locked position.

Does the package include the strike plate and mounting screws or just the lock cylinder and two keys?

The box contains one lock cylinder and two keys; a strike plate and mounting screws are not included and must be sourced separately.
