Description
Traditional Surface Security with the Union 1116 Rim Deadlock
Securing traditional timber doors, garden gates, and outbuildings presents a unique set of joinery challenges. Many older external doors or narrow ledged and braced doors simply do not have the internal thickness required to accommodate a standard mortice lock without seriously compromising the structural integrity of the timber. Cutting a deep mortice pocket into a heritage door can weaken the stile and leave thin wood on either side, which creates an obvious point of failure for intruders or causes warping as the seasons change.
The Union 1116 Black Japanned 108Mm Rim Deadlock solves this fundamental issue by mounting directly to the internal surface of the door leaf. Engineered by one of the most trusted names in British architectural ironmongery, this robust deadlock offers positive key-operated deadlocking without removing critical mass from your door. The solid deadbolt extends firmly into the surface-mounted staple on the door frame, anchoring the timber firmly against forced entry.
Finished in a resilient traditional black japanned coating, this hardware looks entirely natural on cottage entryways, rustic outbuildings, and traditional perimeter gates. At Doorfit, we supply this timeless lock to homeowners and trade professionals seeking an authentic period aesthetic paired with uncompromising mechanical reliability.
Key Operational and Architectural Features
Surface-Mounted Simplicity
Installing the Union 1116 Black Japanned 108Mm Rim Deadlock requires minimal timber removal. Because only a single keyhole needs to be prepared through the door face, you preserve the strength of older or narrower timber doors while drastically reducing your fitting time on site.
Resilient Black Japanned Finish
The hard-wearing black japanned enamel provides a tough barrier against ambient moisture and rust. This period-correct finish complements black antique ironmongery, cast iron hinges, and untreated or stained timber doors without looking modern or out of place.
Positive Mechanical Deadlocking
Unlike spring-operated rim nightlatches that can be slipped with a plastic card, this dedicated deadlock requires deliberate key operation from either side. When thrown, the solid steel bolt deadlocks into position, keeping the door firmly closed against external pressure.
Proven Internal Mechanism
Constructed with high-grade internal components, the Union 1116 offers smooth key rotation and long-term durability. It withstands frequent residential use without internal sticking or jamming, giving you dependable daily service for years to come.
Step-by-Step Installation Pipeline
Installing a surface rim lock is straightforward when following an orderly process. Follow these stages to ensure proper alignment and smooth deadbolt travel.
Stage 1 - Position and Backset Marking
Hold the main lock case against the inside face of the door at your chosen working height. Ensure the front edge of the case sits flush with the closing edge of the timber. Mark the exact centre of the keyhole through the rear of the lock body onto the wood.
Stage 2 - Keyhole Preparation
Drill cleanly through the timber door using an appropriate wood bit, taking care not to splinter the timber as the drill exits the external face. Shape the keyway accurately using a small pad saw or fine file so the key can rotate smoothly from both the inside and outside.
Stage 3 - Securing the Lock Body
Position the lock body over the newly cut keyway and insert the key to test the internal clearance. Once aligned correctly, drill pilot holes into the timber to avoid splitting, then secure the lock case using sturdy wood screws matching the black finish.
Stage 4 - Frame Staple Alignment
Close the door and turn the key to extend the bolt against the door frame. Mark the exact top and bottom positions of the bolt on the frame jamb. Mount the box staple to receive the bolt freely, ensuring there is no binding or rattling when the door is secured.
Practical Applications and Advice
The Union 1116 Black Japanned 108Mm Rim Deadlock is especially suitable for external shed doors, side gates, cellar doors, and internal cottage rooms where morticing is impractical. When fitting to external gates, we recommend pairing the lock with a suitable protective canopy or applying a light coating of graphite lubricant to the internal mechanism annually. Avoid using thick wet oils inside lever lock mechanisms, as these attract airborne grit and saw dust, which can cause premature wear over time.
If your door frame is flush with the door leaf, the included staple fits cleanly onto the architrave. For doors that are rebated or sit back from the frame casing, simple wooden packing behind the staple may be required to achieve seamless alignment between the bolt and the strike plate.

Trade Advice on Heritage Installations
When fitting rim deadlocks on exterior garden gates exposed to driving wind and rain, timber movement is common throughout the year. We advise setting your box staple with approximately two millimetres of clearance above and below the deadbolt. This prevents the bolt from binding if the gate sags slightly during wet winter months, saving you unnecessary adjustment visits down the line.
