Description
DP703BJ 100mm Black Japanned Rim Dead Lock
Securing traditional timber doors presents unique challenges, especially when working on historic properties, rustic cottages, garden gates, or heritage outbuildings. Standard modern mortice locks require deep internal pockets to be chiselled into the door stile, which can easily weaken slender vintage timbers or ruin period joinery. When you are looking to preserve the physical structure and aesthetic charm of older woodwork while achieving straightforward physical security, a dependable surface mounted solution is often the ideal approach.
The Dp703Bj 100Mm Black Japanned Rim Dead Lock offers an authentic, robust answer to these architectural requirements. Featuring a classic black japanned baked enamel finish, this lock sits directly on the internal face of the door leaf, operating in tandem with a securely fastened frame keep. It delivers reliable key operated security without demanding intrusive routing work, making it exceptionally popular for renovations, shed doors, store rooms, and traditional domestic settings where surface mounting is preferred.
Manufactured to provide durable manual deadlocking, this hardware unit brings dependable protection together with period appropriate styling. The deep dark gloss of the japanned coating protects the underlying ironwork against moisture, light knocks, and everyday handling, ensuring your timber entrance maintains both functional reliability and historic visual character for years to come.
Key Features and Installation Workflow
Authentic Black Japanned Protective Coating
The Dp703Bj 100Mm Black Japanned Rim Dead Lock is treated with a traditional black japanned finish. This lustrous, hard wearing resin coating provides an attractive glossy look that complements antique ironmongery, hand forged latches, and period timber architecture across both heritage homes and outbuildings.
Simple Surface Mounted Installation
Rather than cutting away substantial sections of timber, this rim dead lock fixes directly onto the internal door face. You only need to bore a single clean hole through the door stile for the keyway, keeping the timber core strong and greatly reducing fitting time for joiners and tradespeople.
Compact 100mm Case Dimensions
With a compact 100mm case width, this dead lock is particularly well suited to narrow door stiles, ledged and braced doors, and internal storage rooms. It delivers dependable physical throw engagement into the matching surface frame keep while maintaining an unobtrusive profile on the timber face.
Dedicated Deadbolt Manual Security
As a dedicated dead lock, this unit operates solely via key rotation to project and retract a solid metal bolt. This makes it ideal for secondary security, secure utility storage, or doors paired with separate passage latches, ensuring the door stays firmly locked when unattended.
Practical Guidance and Application Context
When restoring older properties or outfitting timber garden structures, matching hardware to the door construction is critical. Ledged and braced timber doors, commonly found on cottages, workshops, and side entrances, often lack the depth required for large mortice pockets. Installing a mortice lock into such doors can lead to split timber or uneven weight distribution. A surface mounted lock like this black japanned model eliminates that danger entirely, securing directly to the solid face boards and distributing fixing stress evenly across the timber.
For optimal performance, ensure that the door and frame are properly aligned prior to mounting the lock body and keep. Because rim locks bridge the physical gap between the moving door leaf and the static door frame, small alignment changes caused by weather or seasonal timber movement can affect operation. Fitting the lock body securely with suitable wood screws and allowing a modest clearance around the bolt will deliver smooth key turning in every season.
Joinery Note. Always ensure the keyway hole drilled through the door leaf is clean and perpendicular. Lubricate the internal bolt mechanism periodically with light graphite powder rather than heavy grease to keep the key movement smooth and free from trapped debris.

Frequently Asked Questions
What makes a black japanned finish different from standard paint?
A japanned finish is a traditional baked enamel coating that fuses directly to the underlying ironwork. It provides a deeper, glossy black surface that resists everyday abrasion and moisture much better than standard air dried domestic paints.
Can this dead lock be fitted to external gates or sheds?
Yes, this lock is widely used on garden sheds, workshop doors, and wooden gates. For external installations exposed to heavy rain, we recommend occasional light oiling or graphite treatment to keep the internal working parts moving freely.
Does this lock include a spring latch for closing?
No, this is a dedicated dead lock, meaning it only features a deadbolt operated by a key. If you require a door handle to hold the door shut when unlocked, pair this unit with an independent rim latch or thumb latch.
Can extra keys be cut for this lock?
Yes, the lock is supplied with standard patterned keys which can be duplicated by most professional locksmiths or key cutting specialists using standard blanks.
