Brass-Plated 12-Inch Latch Protector
The Tuff Stuff MDK312 is a steel security plate with a bright brass US3 finish that spans twelve inches. Interlocking brackets cover the latch area to resist forced entry on in-swinging doors. Mounting screws are included for residential, commercial or industrial installation.
Suits In-Swinging Doors Only
This protector is designed exclusively for in-swinging door applications where the latch is exposed to attack. Buyers with out-swinging doors, sliding doors or frames that cannot accommodate a twelve-inch plate should look at alternative hardware.
Twelve-Inch Interlocking Length
The twelve-inch interlocking span is the critical dimension that determines whether the plate covers the latch and strike gap on a specific door. Verify the door stile width and hardware spacing before purchase to ensure full coverage.

Questions about this item
Will the 12" interlocking latch protector fit the existing mortise on my older in-swinging door?
The MDK312 is 12" long and designed for in-swinging doors; check your current mortise length and backset to confirm alignment before installing.
How can I verify the bright brass finish and interlocking brackets are correctly installed?
After mounting, the bright brass US3 surface should sit flush on the door edge and the interlocking brackets must engage the frame strike when the door is closed.
Does the box include the mounting screws or do I need to purchase them separately?
The box comes with the required screws for installation; no additional fasteners are needed.
