Is This the Right End Clamp for Your Module?
The correct end clamp depends on more than the appearance of the component. Module thickness, clamping geometry, rail interface, and fastening method should be confirmed before ordering.
1. Module Type
Frameless & glass PV modules
2. Module Thickness
Confirm the actual glass or module edge thickness.
3. Clamp Geometry
Select the appropriate clamp height and contact configuration.
4. Rail Profile
Confirm the clamp base and fastener interface with the mounting rail.
5. Fastener
Select the appropriate bolt / T-bolt and fastening configuration.
Not sure which configuration you need?
Send us your module drawing, module thickness, and rail profile. We can review the interface before quotation.
