The Fastensol Black End Clamp is used to secure the outer edges of a solar panel array to the mounting rail, fixing the panel firmly at each end of the row. This 30mm variant is sized specifically for solar modules with a 30mm frame thickness, and forms part of the wider MCS-certified Fastensol pitched roof mounting system, so it can be specified with confidence on MCS-compliant installations.

Check Panel Frame Thickness Before Ordering: This clamp is sized specifically for 30mm panel frames. Fastensol End Clamps are also available in 35mm and 40mm versions — fitting the wrong size will not clamp the panel securely, so confirm your module's exact frame depth from its datasheet first.
MCS Compliance: This End Clamp Kit is listed as a certified component within Fastensol's MCS IK0251 pitched roof installation kit certification. For an installation to remain MCS-compliant, roof pitch, wind uplift design values, and rail/hook combinations must match the certified system configuration — always check the current MCS certificate and installation manual before specifying.
Compatible System: Designed for use with the Fastensol GS/H-profile rail system, alongside Fastensol Middle Clamps, Universal Clamps, and roof hooks (pantile, plain tile, slate, or standing seam depending on roof type).
Precise 30mm Fit
Sized specifically to a 30mm panel frame depth rather than a spring-loaded universal range, giving a snug, consistent clamping force along the full width of the module edge.
Row-End Security
Positioned at the outer ends of a panel row, this clamp takes the full edge load where there's no adjacent module to share fixing points with — a role distinct from mid-row clamping.
Corrosion-Resistant Aluminium
Built from aluminium construction to withstand sustained outdoor exposure without the finish or structural integrity degrading over the system's service life.
MCS-Certified System Component
Included as a certified component of Fastensol's MCS 012 pitched roof installation kit, supporting compliant specification on residential MCS installations.
Rated for UK Weather
Part of a system rated to withstand wind loads up to 60m/s and snow loads up to 2.0kN/m², suitable for the majority of UK roof exposures up to 20m building height.
Multi-Roof Compatibility
Works across tiled, slate, and sheet metal roof cladding types when paired with the appropriate Fastensol roof hook, on slopes up to 60 degrees.

What's the difference between this and a Universal Clamp?
This is a fixed 30mm end clamp, sized for a specific panel frame depth, whereas the Fastensol Universal Clamp is spring-loaded and covers a 30–46mm range and can function as either a mid or end clamp. If your frame thickness is exactly 30mm and you only need row-end fixings, this clamp is a dedicated fit; the Universal Clamp offers more flexibility across different panel thicknesses.
How do I know if my panel needs a 30mm, 35mm or 40mm end clamp?
Check your solar panel's datasheet for the frame depth (sometimes listed as frame thickness or module depth). Fastensol End Clamps are supplied in 30mm, 35mm, and 40mm sizes to match common panel frame profiles — always match the clamp size to your specific panel.
Can I use this clamp for a mid-row fixing position?
No — this is an end clamp only, designed to secure the outer edge of a panel row. For mid-row fixings between two adjacent panels, use a Fastensol Middle Clamp or a Universal Clamp rotated into the mid-clamp position.
Does this clamp affect MCS compliance for my installation?
This End Clamp Kit is listed as a certified component of Fastensol's MCS IK0251 pitched roof installation kit. To keep the overall installation MCS-compliant, it needs to be used within the certified system configuration, matched to the correct rail, hooks, and roof type for your project.
What roof types is this clamp suitable for?
As part of the Fastensol rail system, it's suitable for pitched and flat roofs with tiled, slate, or sheet metal cladding, on slopes up to 60 degrees, provided the correct roof hook is used for your specific roof construction.
