Quick Answer
Select edge trim grip range from the actual finished panel thickness, including paint, coating or stacked layers. The panel should sit within the manufacturer's stated grip range without bottoming out or pulling off. Also check edge radius, installation direction, bend radius and whether a sealing bulb is required. A short trial piece is the safest way to confirm retention.
Key Selection Factors
| Factor | What to check | Why it matters |
|---|---|---|
| Panel thickness | Measure finished thickness with calipers | Determines the basic grip range |
| Edge condition | Check burrs, coating and radius | Affects insertion and carrier engagement |
| Routing | Record straight runs and tight corners | Confirms minimum bend capability |
| Function | Protection only or edge trim seal | Determines whether a side/top bulb is needed |
Recommended Buying Process
- Measure the application at several points and record minimum and maximum values.
- Share a section drawing, clear photos and details of the mating surface.
- Confirm material, color, mounting method, operating environment and order quantity.
- Test a sample on the real assembly before approving mass production.
Common Specification Mistakes
- Using nominal sheet gauge instead of finished thickness
- Choosing a range that is too large and loses retention
- Ignoring paint or powder-coat buildup
- Skipping pull-off and corner installation tests
What to Include in Your RFQ
Send the application, cross-section dimensions, mating-part dimensions, preferred material, color, length, quantity and packaging request. If the profile replaces an existing part, include an uncompressed sample and photos showing where it is installed. Onaseal can review drawings or samples for OEM/ODM production.

Frequently Asked Questions
What does grip range mean?
Grip range is the panel-thickness interval that an edge trim is designed to hold securely.
Should the panel thickness be in the middle of the range?
A middle-of-range fit is often a useful starting point, but carrier design and panel condition must still be tested.
Can edge trim bend around corners?
Yes, many profiles bend, but minimum radius varies by carrier and profile geometry. Send a corner photo or drawing for review.
