Brass-Plated Latch Protector

The Tuff Stuff MDK306 is a 6-inch interlocking latch protector finished in bright brass. It is designed for in-swinging doors in residential, commercial and industrial settings. The steel body uses interlocking brackets to shield the latch area from forced entry. Mounting screws are included in the box.

Steel Construction and Finish

The unit is built from steel with a brass-plated US3 coating that resists corrosion during normal exposure. No moving parts or electronics are present, so the protector adds no operational noise or power draw. Thermal performance is not a factor for this passive hardware component. Installation relies solely on the supplied fasteners.

Reinforces Vulnerable Latch Area

This protector replaces an unguarded strike plate or a basic latch guard that leaves a gap exposed to prying tools. The interlocking design closes that gap, making the jump worthwhile when the door frame cannot accept a deeper deadbolt or when existing hardware shows signs of attack. It is not suited for out-swinging doors or for frames that require a surface-mounted vertical rod.

Questions about this item

How do I install the 6-inch latch protector on an in-swinging door, and what step is often missed?

Mount the interlocking brackets on the door and frame so they engage when closed, using the supplied screws; the step often missed is confirming the door swings inward, as this protector is not designed for out-swinging doors.

What maintenance will the brass-plated steel latch protector need over time?

The bright brass finish on steel may tarnish; clean it periodically with a non-abrasive brass polish and tighten the mounting screws if they loosen from repeated door movement.

What is the first limit you hit when the latch protector takes repeated forced-entry attempts?

The interlocking brackets are designed to resist forced entry on in-swinging doors, but sustained heavy impact can eventually deform the steel brackets or strip the screw holes in the door or frame.
