Identify the connection before the material
Official catalogs distinguish screw-on and push-on product families. These labels describe a connection; they do not establish that two pads of equal length fit the same frame. Ask for a connector photograph on both the pad and the frame side.
| Inquiry detail | Screw-on candidate | Push-on candidate |
|---|---|---|
| Connection evidence | Insert and screw interface | Insert and receiving socket |
| Matching information | Original screw and frame reference | Connector profile and frame reference |
| Sample question | Is the fastening screw included? | Which receiving fitting was the sample checked against? |
Do not approve a conversion by appearance
If a supplier proposes a different mounting system, treat it as a new compatibility question. Ask what frame component must change and whether the original frame manufacturer supports that change. A purchasing catalog is not an installation manual.
Keep material, shape and mounting in separate spreadsheet columns. “Clear silicone” does not answer how the pad attaches. A product family photograph may show several variants; include the exact supplier code in the quotation.
A useful inquiry line
“Please quote pads matching the attached connector photographs and reference sample. Confirm mounting type, pad dimensions, supplier code, package unit, included fasteners and whether a sample can be supplied before bulk approval.”
If the supplier cannot identify the connector, mark the line unresolved. Do not let a low price or matching color silently become approval of fit.
