Why choose the F-UC-B universal clamp?

F-UC-B is the LAMPS sellable SKU for the black clamp line, while UC-GS is the Fastensol article reference for the universal clamp. Including both codes helps buyers find the right item whether they are searching by stock code, manufacturer code or installer schedule.

The clamp is designed for the Fastensol GS rail system and supports framed modules from 30mm to 46mm thick. The panel frame thickness must be checked before ordering because universal does not mean suitable for every module or every rail profile.

How does one clamp cover mid and end positions?

Fastensol lists the UC-GS clamp function as both mid clamp and end clamp. This means the same clamp type can be used between modules and at the outer edge of an array when the installation follows Fastensol instructions and the module manufacturer’s clamping zones.

For merchants and installers, this helps simplify stock holding and picking. A single black clamp line can support more than one position on a GS Roof layout, reducing the risk of sending separate mid and end clamp products for the same rail system.

What installation details matter?

The datasheet lists a hexagon socket M8 drive and a 14.5Nm maximum fastening torque. It also gives recommended torque guidance for end clamp and inter clamp positions, so installers should follow the latest Fastensol instructions supplied with the product.

The clamp needs to seat correctly in the rail before final tightening. It should not be forced into place against a module frame or used outside the listed frame thickness range.

Material, finish and matching parts

The clamp is made from AL6005-T5 aluminium and SUS304 stainless steel. The black finish is suited to black-framed panels and darker array edges where the clamp is visible from ground level.

Use F-UC-B with compatible Fastensol GS rail, roof hooks or slate brackets, rail splices and rail end caps where required. Browse Fastensol GS Roof or the wider solar mounting systems range for related parts.
