TL;DR
Select a multipoint lock from the actual door section, not the material name alone. Timber doors require a controlled edge recess, sufficient remaining section and reliable fixing support. Aluminium doors require enough profile depth, clearance from chambers or thermal breaks, planned reinforcement and compatible keeps. Both need a straight long-faceplate path, aligned lock points and representative sample approval.
Start with the Multi-point Locking Systems product hub, then use this narrower guide to define the required function and approval evidence.
Quick Answer
Obtain a dimensioned door cross-section and elevation. Overlay the central case, full faceplate, every lock point, cylinder and handle centres, fixings and keeps. Check remaining material, reinforcement, seals, drainage or profile chambers, fabrication access and transport protection. Approve the exact lock-door combination before machining a production batch.
Door material is only the first filter
Timber and aluminium describe broad construction families, not one standard edge section. A timber leaf may have solid lippings, engineered cores, glazing pockets or reinforcement. An aluminium entrance door may use many profile depths, chambers, thermal breaks and screw channels. The buyer needs the actual cross-section and fabrication details for the opening.
Mark one door-edge datum and show the central case, long faceplate, remote points, cylinder, spindle and fixing paths. The overlay should also show glass, panels, seals, drainage and other hardware. A catalogue statement such as “for timber door” cannot replace this dimensional check.
Check central-case depth and remaining section
The central gearbox or lockcase is normally the deepest part of a multipoint system. Confirm backset, case depth, height and all projections against the door section. On timber, check the remaining lipping and core after routing. On aluminium, check that the case clears internal walls, connectors and thermal components without unauthorised cutting.
Do not reduce reinforcement or profile walls during site fitting to make a case enter the opening. If the proposed lock does not fit the approved section, return the conflict to the door designer and hardware supplier. Record the final cross-section and lock drawing revision with the sample.
Plan the long faceplate and edge preparation
TOPTEK internal material notes that a long multipoint faceplate can be affected by bending during transport or installation. The door edge needs a straight, correctly sized path that supports the strip without forcing it into a curve. Check plate width, thickness, length, cut-outs, end clearance and the relationship to the finished edge or extrusion channel.
For timber, control the routed pocket and avoid splitting or unsupported fixing zones. For aluminium, confirm whether the plate sits flush in a designed channel and whether fabrication tools can reach every cut-out. Protect the assembly during storage and transport; screws should secure a correct fit rather than pull a distorted strip flat.
Match fixings and reinforcement to the load path
The central case and remote lock points transfer operating and closing loads into the door, while the keeps transfer those loads into the frame. Specify the fixing type, length, thread engagement and reinforcement for the actual substrate. A screw that grips one thin wall or a weak timber zone may loosen even when the first sample appears to operate.
Show reinforcement before fabrication. Check that through-fixings for handles or cylinder furniture do not collide with the mechanism. If alternative fixings are proposed, review them with the door manufacturer and the applicable doorset requirements rather than accepting a site substitution from appearance alone.
| Compatibility item | Timber door review | Aluminium door review |
|---|---|---|
| Central case | Lipping, core and remaining routed section | Profile depth, chambers and thermal elements |
| Faceplate | Straight routed edge and supported fixing zones | Channel fit, cut-outs and extrusion tolerances |
| Fixings | Substrate, pilot preparation and split risk | Thread engagement and reinforcement |
| Keeps | Frame material, movement and seal pressure | Frame profile, access and adjustment |
| Sample | Representative routed door section | Representative fabricated profile assembly |
Coordinate keeps, seals and door movement
Each hook, bolt or roller needs a compatible keep at the correct datum. Timber frames and aluminium frames use different sections and may move differently under installation, weather, gasket compression and building tolerances. Map every lock point, the closed-door position and the available adjustment range from current drawings.
Compare the TOPTEK Auto Lock reference and PD1000 family reference only as starting points. Confirm the supplied locking-point pattern, sequence and keeps on the exact quotation. A website photograph is not a preparation template.
Approve the opening as a system
Multi-point Locking Systems is only one part of the opening. The door leaf, frame, strike or rod interfaces, trim, cylinder, closer, power components where applicable, and the installation conditions all influence the result. Use the TOPTEK multipoint product hub to discuss the mechanism family, then coordinate the actual timber or aluminium door section with current drawings. A catalogue family name cannot replace a coordinated opening schedule.
Give every opening a unique number. Attach the current elevation, door and frame construction, thickness, swing, handing, hardware interfaces, finish, evidence requirements and sample reference. When one field changes, reopen the affected checks instead of assuming that the earlier approval remains equivalent.
Use a state-based approval test
Write the normal, locked, authorised-entry, emergency-egress, override and abnormal states that apply. For each state, record what the user does and what each latch, bolt, rod, lever, key or electrical input must do. Mark a state N/A when it truly does not apply; a blank field hides a decision.
Operate the labelled sample in the same sequence. Review from both sides of the door, then repeat the critical checks in representative preparation. Photograph labels and interfaces, but preserve the signed state table as the controlling approval record. Appearance alone cannot prove function.
Separate product evidence from project approval
A certificate, test report or declaration applies only to the product, construction, standard and configuration named in its scope. A project still needs to determine whether that evidence is the document it requires. Request current original records and compare model identifiers with the quotation, drawing and sample.
Do not turn an internal development test, a website badge, a similar model or a customer statement into third-party certification. If evidence remains open, record the missing document, responsible reviewer and due date. This draft intentionally avoids unsupported cycle, load, corrosion, fire or material claims.
Buyer approval checklist
- Opening number, door type, frame and swing
- Plain-language operating sequence from both sides
- Exact product, trim and interface references
- Door preparation and installation tolerances
- Required model-specific evidence and revision
- Labelled sample and acceptance owner
- Packaging, site inspection and handover controls
- Repeat-order change-control reference
Common mistakes and project risks
Common mistakes include selecting by door material without a cross-section, overlooking central-case depth, removing profile walls or timber reinforcement on site, pulling a bent faceplate flat with screws, using one keep position for a changed gasket condition and approving a bench sample without representative door preparation. These errors can create repeat machining, intermittent locking or damaged doors.
The practical consequences can include re-machining, replacement hardware, revised wiring or keying, delayed inspection and uncontrolled site modification. Stop approval when the operating sequence, physical interface or evidence scope is unclear. A question recorded before production costs less than an assumption discovered across installed doors.
TOPTEK evidence and product scope
TOPTEK uses product-family material, model images and internal engineering observations to frame the buyer questions in this guide. These sources support a configuration discussion; they do not make every option, dimension or approval universal. The supplied configuration still has to be identified on a current drawing.
Use the TOPTEK resources centre for product documents and the applicable evidence request. Where a source describes internal testing, treat it as internal verification unless an original third-party document for the quoted configuration is separately reviewed.

Why TOPTEK: turn selection into a controlled record
TOPTEK can review a marked-up schedule, translate shorthand into operating and interface questions, and identify missing information before quotation. The objective is not to guess the designer’s decision; it is to give the responsible parties a clear configuration to approve.
Quotation, drawing, sample label and order acknowledgement should carry the same reference. This lets door manufacturers, distributors, integrators and project teams detect substitutions or later changes. It also creates a practical basis for repeat-order inspection.
Two-level CTA
For an initial review, send the opening list, door images or elevations and the required user sequence. Highlight unknowns. TOPTEK can return a focused question list without presenting assumptions as confirmed facts.
For a formal RFQ, submit the approved schedule, drawings, interfaces, evidence requirements and sample protocol through the TOPTEK contact page. Request a configuration-specific response and identify the person authorised to approve deviations.
Conclusion
Good hardware selection is a controlled translation from user behaviour to product configuration. Define the function, verify the physical interfaces, check the applicable evidence and demonstrate the identified sample. Do not let a general product name carry decisions it cannot contain.
Preserve the result through procurement, production, installation and handover. That discipline reduces avoidable replacement risk while keeping every TOPTEK statement inside the evidence and configuration actually reviewed.
Frequently asked questions
Can the same multipoint lock be used for timber and aluminium doors?
Only if the exact case, faceplate, fixings, locking points, keeps and door sections are compatible and approved. The material name alone does not prove fit.
Why is case depth important for an aluminium profile?
The central case must clear internal walls, chambers, reinforcement and other components without unauthorised cutting.
What should be checked when routing a timber door?
Check lipping and core construction, remaining section, straight faceplate support, fixing zones, glazing and all remote lock-point pockets.
Can screws be used to straighten a long faceplate?
No. Investigate transport damage, the door-edge recess and plate condition. Fixings should secure a correct fit rather than force a distorted strip.
What belongs in the RFQ?
Send door and frame sections, complete lock geometry, operation sequence, reinforcement, fixings, keeps, seals, preparation drawings and a representative sample plan.
