A chain door guard is a simple secondary latch for a swinging entry door: a slide plate mounts to the door face and a chain-and-ball assembly mounts to the jamb, so the door can be opened a few inches to see or speak to a caller while the chain holds it from swinging wide. It is released from inside only, so it functions as an occupancy device rather than a lock, and it is commonly added alongside a keyed lockset and deadbolt on apartment and residential entrance doors.

This Tuff-Stuff guard is a brass unit, a finish and material long used on door hardware for its corrosion resistance and its match to brass knobs, hinges and strikes. Installation is surface-mounted with screws through the two plates, which makes it a straightforward retrofit on an existing door and frame without mortising or boring.

The two-piece format means alignment matters more than fastening: the jamb plate sits on the hinge-side of the stop so the chain runs square to the door when closed, and both plates want solid wood or blocking behind them rather than casing alone.

Key Features

• Brass construction and finish, which resists corrosion and tarnish better than plated steel in humid entryway conditions
• Chain-and-ball style guard: the ball end slides into a keyhole slot in the door plate and travels in a channel to limit door swing
• Operated and released from the inside only, giving an occupant a way to answer the door without fully unlatching it
• Surface-mounted two-piece design - door plate and jamb plate - so no mortising or boring of the door is required
• Works as a secondary device in addition to the primary latch or deadbolt rather than as a replacement for either
• Non-keyed guard, sold as Tuff Stuff model TUF50 in polished solid brass
• Mounting screws are supplied with the unit
• Finish coordinates with brass knobs, hinges, strikes and escutcheons on the same opening

• Apartment and multifamily unit entrance doors
• Single-family residential front and side entry doors
