Description
Traditional Surface Security for Outward and Inward Timber Doors
Securing external timber gates, workshop doors, and traditional period outbuildings often poses distinct joinery challenges. Many historic or lightweight timber doors lack the internal thickness required for deeply morticed locks, which can structurally weaken the timber stiles. In situations where an internal mortice pocket is impractical, tradespeople and property owners require a heavy-duty, surface-mounted locking unit that provides physical resistance against forced entry while withstanding damp British weather conditions.
The Union 1139 Black Japanned 152Mm R.Hand Rim Deadlock resolves this installation dilemma by delivering dependable perimeter security in an accessible surface-fixed format. Built by one of the most respected names in British architectural ironmongery, this heavy pattern rim lock bolts directly to the internal face of the door. It distributes physical stresses across the face of the timber rather than concentrating forces inside a hollowed mortice cavity, ensuring the long-term structural integrity of your woodwork.
Finished in a classic black japanned protective coating, the unit offers proven durability and corrosion resistance against outdoor moisture. Whether you are replacing a worn period lock on a residential side gate or outfitting a commercial storage shed, this lock delivers straightforward deadlocking control operated exclusively by key from both sides, preventing unauthorised access without complex internal lever mechanisms.
Key Features and Practical Benefits
Resilient Black Japanned Finish
The hard-wearing black baked enamel coating creates a resilient seal against humidity, dirt, and moisture, making it ideal for outdoor sheds, cellar entrances, and perimeter garden gates.
Solid 152mm Heavy-Gauge Casing
A wide 152mm case spreads the fixing footprint across the door stile, delivering high pull resistance and reliable holding power against physical tampering or forced leverage.
Dedicated Right Hand Configuration
Pre-configured right hand orientation ensures that internal levers and the locking bolt engage seamlessly with standard right hung doors without awkward reversal steps.
Dual-Sided Key Operation
Positive deadlocking is managed entirely by key from either side, preventing intruders from simply reaching around an open panel or aperture to flick a snib latch open.
Installation and Operational Workflow
Step 1 Handing and Preparation
Confirm your door swing before installation. This right hand lock suits inward opening doors hinged on the right, or outward opening doors hinged on the left. Align the lock body flush with the closing edge of the timber stile.
Step 2 Keyway Drilling
Mark the backset accurately onto the door face. Drill a clean, straight keyhole clearance hole through the timber using a sharp auger bit to allow smooth key entry from the external side without binding against the wood.
Step 3 Case and Staple Fixing
Secure the heavy-gauge lock case using suitable woodscrews. Mount the surface keep box, also known as the staple, directly onto the frame, ensuring uniform alignment with the sliding deadbolt path.
Step 4 Final Operational Testing
Test key rotation from both sides while the door remains open, checking smooth bolt extension. Close the door and test locking engagement into the frame keep to verify clean clearance under normal seasonal wood movement.

Frequently Asked Questions
How do I verify if my door requires a right hand rim lock?
Stand on the inside of the room or property looking at the door as it closes toward you. If the hinges are located on your right hand side, you require a right hand lock. If you are standing outside an outward swinging gate hinged on the left, this right hand unit is also the correct ironmongery selection.
Can this rim deadlock be used in exposed outdoor environments?
Yes, the Union 1139 Black Japanned 152Mm R.Hand Rim Deadlock features a traditional black japanned finish. This baked enamel process forms a barrier against weather elements, making it an excellent choice for outdoor gates and garden buildings. We recommend applying a light machine oil to the keyway occasionally to keep the internal levers moving smoothly.
Does this lock latch automatically when the door swings shut?
No, this unit is a true rim deadlock rather than a rim latch. It features a solid deadbolt that extends and retracts strictly via key operation. This design prevents you from accidentally locking yourself out when walking into your garden or shed without your keys.
What fixings and parts are included in the box?
The package contains the main 152mm rim lock case, matching surface frame staple keep, cut keys, and necessary mounting screws for quick installation directly onto solid timber surfaces.
