Seamless Security for Double Door Configurations
Pairing double internal doors or exterior timber French doors brings light and a sense of open space to any property. However, managing how those twin doors close and remain secure can present a genuine joinery challenge. Without a firm locking mechanism on the passive door leaf, the entire set can rattle, flex in draughts, or fail to latch correctly. The secondary leaf must sit immovably in its frame whenever the active door swings open, yet it must also unlock quickly and effortlessly whenever you wish to throw both doors wide open.
The 203 x 19mm Lever Action Flush Bolt Polished Chrome provides a refined and dependable answer to this everyday installation puzzle. Recessed neatly into the door timber, this architectural fitting remains tucked away out of sight, preserving the clean sightlines of your joinery while providing robust mechanical retention. Whether you are refurbishing classic period French doors in a domestic living room or fitting out busy modern office meeting rooms, this hardware delivers the rigidity, stability, and smooth tactile action needed to keep your doors operating reliably day after day.
Step by Step Installation and Operation Pipeline
Stage 1 Timber Mortice Preparation
Accurate timber preparation ensures your flush bolt sits perfectly level with the door surface. Joiners cut a neat mortice slot measuring 25mm deep along the door edge or face, accommodating the body and 38mm wing. Taking time during marking out guarantees an unobtrusive fit that preserves your door profile.
Stage 2 Body Alignment and Fixing
Once the channel is prepared, the flush bolt drops neatly into the recess. Using the matched screws from the supplied fixing pack, fix the unit firmly into the timber core. A secure, rigid installation prevents twisting or binding during daily operation, keeping the bolt mechanism perfectly square.
Stage 3 Strike Plate Positioning
The matching strike plate installs directly into the door frame head or threshold sill. Accurate alignment with the 11mm bolt diameter ensures smooth engagement without catching. Morticing the strike plate flush prevents scuff marks and guarantees positive closure whenever the secondary door leaf is brought home.
Stage 4 Mechanical Lever Engagement
A smooth flick of the integrated finger lever pushes the solid shoot forward by 16mm into the keep. The mechanical leverage gives positive feedback under hand, securing the inactive door against seasonal timber movement while allowing fast release whenever you want both doors opened wide.
Key Features and Practical Applications
Double door installations rely heavily on the integrity of the inactive leaf, often referred to as the slave door. If that secondary door moves, the primary latch will not catch neatly, resulting in rattles and security vulnerabilities. Fitting the 203 x 19mm Lever Action Flush Bolt Polished Chrome at the top and bottom of the inactive door transforms it into a solid, immovable post against which your primary door can latch with total confidence.
- Versatile Edge or Face Mounting Flexible installation allows joiners to recess the hardware into the closing edge of the door for hidden operation, or directly onto the face of the leaf if preferred.
- Substantial 16mm Bolt Throw The long shoot travel bridges standard frame clearances and under-door gaps, driving deeply into the frame head or floor socket for exceptional resistance against pushing forces.
- Polished Chrome Finish The mirror-like chrome plating pairs attractively with modern chrome handles, stainless steel hinges, and contemporary interior decor schemes.
- Effortless Lever Actuation The internal lever mechanism multiplies your finger effort, making engagement smooth and preventing the finger strain often associated with stiff, spring-loaded slide bolts.
- Complete Installation Pack Supplied with a tailored strike plate and all required timber fixing screws, allowing joiners to finish the job without sourcing extra hardware parts.
Thanks to its sturdy construction and sleek appearance, this flush bolt suits an expansive variety of settings. In private residences, it secures patio French doors, conservatory exits, and folding room dividers separating open-plan living areas. In commercial premises, it serves reliably on pairs of timber doors leading into boardrooms, hotel suites, educational facilities, and administrative offices where simple hardware operation and neat aesthetics are valued equally.

Best Practice Fitting Guidance
For standard height internal double doors, fitting a single flush bolt at the top of the inactive door is frequently sufficient to hold the leaf closed against light draughts. However, on exterior French doors, tall architectural room dividers, or fire resistant door sets, industry best practice is to install two flush bolts, one morticed into the top edge shooting into the frame head, and one fitted into the bottom edge shooting into the floor socket or sill keep. This dual fitting prevents the timber leaf from bowing over time when exposed to differing temperatures and humidity levels between adjoining spaces.
When routing or chiselling the timber pocket, take care to blow away loose shavings before driving in the mounting screws. Pre-drilling pilot holes into hardwood doors will prevent screw heads from shearing and ensure your flush faceplate pulls completely flat against the timber. A touch of light machine oil on the internal pivot pins during routine building maintenance will keep the lever operating silkily for decades of regular use.
