A multipoint door lock links a central gearbox to two or more locking locations along the door edge. OEM approval must align door thickness, faceplate, gearbox, rods, locking points, handle, cylinder and keeps as one system.
HIPAD’s supplied reference lists multipoint locks for 40-80 mm entrance doors. This family-level range does not mean one lock fits every thickness or profile. The selected model still needs a dimensioned drawing and installed sample.
| Specification | Buyer input | Approval evidence |
|---|---|---|
| Epaisseur de la porte | Finished leaf and tolerance | Section drawing and sample |
| Faceplate | Width, length, edge preparation and finish | Door-edge machining drawing |
| Gearbox | Backset, centers, follower and throw | Lock and handle interface drawing |
| Locking points | Type, quantity, spacing and travel | Full-height layout |
| Handle/cylinder | Spindle, fixing centers, cylinder type | Complete hardware schedule |
| Keeps | Frame profile, offset and fixing | Installed engagement test |
Start with the door-edge preparation and central gearbox position. Record the backset, handle-to-cylinder centers, spindle section and faceplate. Then define the rod or extension connections and the exact location of every hook, bolt, roller or other locking element.
Compared with a single-point replacement lock, a multipoint system adds cumulative tolerance along the full door height. A small error at each connection can prevent all points from reaching their keeps at the same time.
Confirm handle spindle engagement, fixing centers and clearance around the gearbox. State the cylinder type, length and cam requirement. For each keep, document the frame profile, offset, fixing support and required engagement. The keeps should secure the door without forcing it out of alignment.
A sample can operate on a bench yet bind after the door is glazed, clad or installed. Check engagement with the finished door weight, seals and frame tolerances. Adjustment may help alignment, but it cannot correct an incompatible gearbox or incorrectly positioned keeps.
The source library identifies steel/zinc-alloy and brass/steel options across related lock families, but it does not disclose a universal product certificate number, security grade, price or MOQ for every multipoint model. Request model-specific material, finish, cycle, load or security evidence where the project requires it.
HIPAD describes OEM/ODM support for dimensions, structures, finishes, logos, molds and packaging. Tooling, MOQ, price and lead time require a project quotation.
The supplied reference lists multipoint locks for 40-80 mm entrance doors. Exact fit depends on the selected model and door profile.
No. Also define centers, follower, faceplate, locking-point layout, connections, handle, cylinder and keeps.
The installed system should reach the model’s intended engagement without excessive force. Verify this on the finished door and frame.
HIPAD supports drawing-based OEM/ODM review. Feasibility depends on the door system, quantities, tooling and performance requirements.
