The Fastensol Universal Clamp (Black) is a spring-loaded, dual-function clamp designed for framed solar panels with a frame thickness between 30mm and 40mm. A single clamp design serves as both a mid clamp (securing two adjacent panels) and an end clamp (securing the outer edge of a row) — simply rotate the head 90° to switch between the two configurations.
Manufactured from Aluminium 6005-T5 and SUS304 stainless steel, the clamp is pre-assembled for fast on-site fitting and clicks into the Fastensol rail channel before final tightening. Its black anodised finish is designed to complement black-framed and all-black solar modules for a discreet, uniform roof appearance.

Materials
Do Not Mix With Other Suppliers' Hardware
Fastensol mounting equipment must not be used with mounting equipment from other suppliers. Mixing rails, clamps, hooks or splices between different manufacturers can compromise structural integrity, will invalidate the 12-year product warranty, and may breach the conditions of MCS certification for the completed installation.
Key Features
Spring-Loaded Universal Fit
The spring-loaded design lets the clamp click into the rail and stay in place before the panel is fitted, rather than dropping out while handling panels — reducing lost parts and speeding up installation.
Dual Mid Clamp / End Clamp Function
Rotate the head 90° to switch the same clamp between a mid clamp (for two adjacent panels) and an end clamp (for a row's outer edge) — one part number covers both roles, simplifying stock and ordering.
Pre-Assembled for Fast Fitting
Supplied pre-assembled, the clamp is ready to fit straight from the box with no loose components to lose or misplace on the roof.
Aluminium 6005-T5 & SUS304 Construction
Built from structural-grade Aluminium 6005-T5 with SUS304 stainless steel fixings for long-term corrosion resistance in exposed rooftop conditions.
Hexagon Socket Drive
Tightened using a standard M8 hexagon socket driver — the same tool used throughout the Fastensol rail system, minimising the tool count needed on site.
Black Anodised Finish
The black anodised coating is designed to blend with black-framed and all-black solar panels, giving a clean, uniform roof appearance for aesthetically sensitive installations.

Frequently Asked Questions
What panel thickness is this clamp designed for?
This Fastensol Universal Clamp (part number F-UC-B) is designed for framed solar panels with a frame thickness between 30mm and 40mm. Always check your panel datasheet for the exact frame thickness before ordering, as Fastensol also offers a wider-range clamp variant for panels up to 46mm.
Can the same clamp be used as both a mid clamp and an end clamp?
Yes. This is the key feature of the Universal Clamp — rotating the clamp head 90° switches it between a mid clamp position (between two adjacent panels) and an end clamp position (at the outer edge of a row), so a single part serves both roles.
What tool do I need to install this clamp?
The clamp is tightened using a hexagon socket driver (Allen key), M8 — the same drive type used across the rest of the Fastensol rail and clamp system, so installers typically need only one tool size for the whole array.
Is the black finish just cosmetic, or does it affect performance?
The black anodised finish is primarily aesthetic, designed to complement black-framed and all-black solar modules, but anodising also provides a protective, corrosion-resistant surface layer — the same 5-year finish warranty applies as on the mill/silver finish.
Can I use this with mounting rails or clamps from another brand?
No. Fastensol components are engineered as a matched system, and mixing Fastensol hardware with mounting equipment from other suppliers is not supported and will void the warranty. Always use genuine Fastensol rails, clamps, hooks and splices together as a complete system.
What warranty does this product carry?
Fastensol backs this product with a 12-year product warranty against defects in material and workmanship, plus a 5-year finish warranty on the anodised coating, from Xiamen Fasten Solar Technology Co., Ltd. The finish warranty is void if the component is not cleaned and maintained in line with AAMA 609 & 610-02 guidance for architecturally finished aluminium, and the full warranty is void if the product is modified, installed incorrectly, or mixed with another manufacturer's mounting hardware.
