For door manufacturers and distributors, the useful question is whether the proposed mechanism matches the whole opening. Start with the existing lock identity and door application, then compare the case, faceplate, locking points and receiving keeps before choosing from TOPTEK’s multipoint lock range.
Use two TOPTEK configurations to see what 92 mm leaves unanswered
| Listed feature | Auto Lock 4592 | PD1000 | Effect on selection |
|---|---|---|---|
| Handle-to-cylinder centres | 92 mm | 92 mm | This identifies one furniture relationship only |
| Faceplate width | 20 mm | 16 mm | The routed channel and supporting door edge differ |
| Faceplate length | 1720 mm | 1414 mm | Compare the full strip and locking-point positions |
| Product application | Automatic multipoint entrance-door configuration | Patio-door multipoint configuration | Establish the door movement and operating sequence before matching dimensions |
These are the listed configurations, not a cross-reference between interchangeable parts. A narrower faceplate does not become a suitable replacement simply because it can enter a wider channel. Its support, fixing locations and keeps still need to match. Equally, a shorter strip does not prove that its locking points line up with the existing frame.
Measure the existing lock from a single reference
Record the maker and model markings, door type and operation first. Describe how the user secures and releases the door: automatic engagement on closing, lifting the lever, or operating the key. A replacement that fits the cut-out but changes that sequence can still be the wrong purchase.
Next, record centres, backset, case depth and height, faceplate width and length, spindle interface and fixing holes. Backset is the distance from the specified faceplate reference to the spindle or cylinder centreline shown on the drawing. Do not substitute an overall case measurement for it.
Use the spindle centre as a stated datum for the vertical positions of every locking point and fixing. Mark whether each position is above or below it. Measure the matching keeps from the same datum. This avoids the common ambiguity of two sketches whose dimensions start at different ends of the strip.
Compare the keeps as well as the lock
The lock and its receiving parts work together. Compare each bolt or hook with the proposed keep’s opening, depth and position. Establish whether the existing keeps can remain or whether a complete replacement set is required. Include the door gap and seal condition because these affect where the closed leaf sits relative to the frame.
For example, finding 92 mm centres on both locks answers the furniture-spacing question. Finding different faceplate lengths immediately opens a second question: where will the remote locking points land? The next useful action is a marked-up lock-and-keep drawing, rather than ordering the closest-looking strip and adjusting it on site.
Specify the replacement for quotation and repeat supply
The Auto Lock product page and PD1000 product page identify the two configurations. Request the current model drawing through TOPTEK technical resources and compare it with your measured opening. Use that drawing to settle the exact backset, fixing and keep arrangement for the item being quoted.
For a distributor building a replacement range, retain a reference record for each supplied configuration: model, operating sequence, full strip drawing and matched keeps. This is more useful for the next order than a stock description such as “92 mm multipoint lock.” It gives purchasing and service teams a way to distinguish variants without relying on appearance.
For door brands developing a new platform, use the same information with the TOPTEK multipoint supply programme. Agree the lock and keep layout before machining a production batch. For a rated opening, retain the applicable assembly requirements when considering any replacement.
Request a replacement configuration review
Send TOPTEK the existing lock markings and a measured sketch, with photographs of the full strip, central case and keeps. Include the door application, required operation and quantity. Ask for the proposed model drawing and a quotation that states whether the keeps, cylinder and handles are included. That makes the offer comparable and gives the sample review a defined configuration.
Frequently Asked Questions
Are all 92 mm multipoint locks interchangeable?
No. Centre distance is only one interface. Backset, case dimensions, faceplate, spindle, locking-point positions, keeps and operating sequence must also match the application.
What should accompany a multipoint replacement enquiry?
Provide the model markings, door application, required operation, a measured full-strip drawing and photographs of the central case and keeps. State the quantity and which surrounding hardware you intend to retain.
