Frequently asked questions
What is the difference between mid and end clamps?
Mid clamps retain neighboring modules; end clamps retain a module at the array edge. Select each against the module frame and rail interface.
Does frame height alone establish clamp compatibility?
No. Also verify frame shape, clamping zone, rail slot, bolt engagement and module installation instructions.
Can framed-module clamps hold frameless laminates?
Do not substitute them. Frameless modules need a compatible laminate clamp and module-specific installation approval.
What tightening torque should installers use?
Use the confirmed instructions for the exact clamp, bolt and module combination. A catalog torque should not override the approved assembly instructions.
Are universal clamps compatible with every module?
No. Check the listed adjustment range and the actual frame and rail geometry before selecting a universal clamp.
