A panic bar order needs two length decisions: how the complete device fits the door, and how much of its face is an operating push surface. For door manufacturers and distributors, confusing these dimensions can produce the wrong configuration even when the hardware appears to fit.
Within its panic exit device range, TOPTEK offers half-length and full-length pushpad configurations in its F5000 rim-device family. Select the configuration first, then agree the supplied length and mounting layout against the door drawing. A catalogue length is not permission to shorten the device on site.
Half-length and full-length describe a meaningful choice
The F5000S and F5000P are the half-length configurations; F5000-1S and F5000-1P are the full-length configurations. The S and P references distinguish stainless steel and painted steel cover options. These details give a distributor a more precise purchase description than simply asking for a stainless panic bar.
The product drawings show why the distinction matters: the half-length version has a separate operating pad and inactive housing section, while the full-length version has a longer operating pad. Do not halve the door width to specify a half-length configuration. The term describes the product arrangement, not a universal dimensional calculation.
Keep three measurements separate
| Measurement | Purchase decision it supports | Information to send |
|---|---|---|
| Door leaf width | Starting size of the opening configuration | Finished width and the edges measured |
| Usable mounting face | Space for the chassis, housing and end support | Glazing beads, stile profile, raised panels and reinforcement |
| Operating pushpad length | The accessible moving surface of the selected device | Half-length or full-length configuration and its drawing |
TOPTEK lists 1045 mm as the F5000 family’s standard length, with customization available. Treat that as a supply reference. It does not establish a minimum door width or a permitted amount to remove. The quotation and drawing should state the actual overall length for the ordered version.
A useful buying insight is that a wider door can still offer less usable mounting space. A glazing bead or raised door detail may obstruct the chassis or end bracket. Send a front view and a section through the mounting area so the supplied device can be reviewed against the surface it will actually occupy.
Agree finished length before door preparation
TOPTEK’s OEM and ODM service includes modifications based on existing product platforms. For an agreed modification, both parties retain the approved sample as a production reference. Apply that approach to the device length, cover option and fixing arrangement together, so the sample approval describes the assembly being purchased.
For a repeat order, retain the same product reference and drawing revision. A finish match alone does not identify the pushpad configuration. If the opening needs a different length, request the corresponding factory option or the exact modification instructions before machining the door.
Manufacturer cutting instructions are specific to their own hardware. For example, Lockwood’s FE-series installation guide gives its own measurement and cutting sequence. Those dimensions are not a cutting rule for TOPTEK devices.
Separate horizontal length from a vertical-rod layout
For a vertical-rod arrangement, the horizontal device and the top and bottom locking interfaces have separate geometry. Ordering a shorter horizontal bar does not resolve an incorrect rod length or keeper position. Record leaf height and the top and bottom interfaces independently.
Use the TOPTEK vertical-rod product reference to identify the arrangement, and coordinate mounting with the door-preparation guide. On a rated opening, the final device, door construction and permitted installation must match the applicable product and project documentation. Dimensional fit alone does not establish that suitability.
Request a length-specific quotation
Send TOPTEK the finished leaf width, one marked photograph or door drawing, and the preferred half-length or full-length configuration. Add quantity, cover finish and destination market. For a vertical-rod device, include leaf height and the meeting-edge arrangement.
Use the TOPTEK enquiry form to request the proposed supply length, matching drawing and sample quotation. You can review the product documentation resources alongside the response. This gives your purchasing and door-production teams one identified configuration to order and reproduce.
Frequently asked questions
Can a 1045 mm F5000 device be cut to fit any door?
No. The standard supply length does not define a universal cutting allowance. Use the instructions for the exact configuration or request an appropriate factory length.
Does half-length mean half the door width?
No. In the F5000 family, half-length and full-length identify pushpad configurations. Specify the complete model and agree the overall supplied length separately.
