The Schletter Mid Clamp Classic Wide secures framed solar modules with frame heights of 30-40mm between adjacent panels on Schletter Classic-profile mounting rails. Pre-assembled from durable anodised aluminium, it offers a firm, gentle grip that spreads clamping load evenly across the module frame edge.
Unlike the click-in Rapid16 range, the Classic Wide clamp uses Schletter's established bolt-through fixing method onto Classic-profile rails, supporting both vertical and horizontal module orientation from a single part.

Key Features
Wide Clamping Surface
The wider clamp foot spreads pressure across a greater area of the module frame, reducing point-loading on the panel edge compared to narrower clamp designs.
Vertical & Horizontal Mounting
Supports modules installed in either portrait or landscape orientation, giving flexibility when planning array layouts on Classic-profile rail runs.
Pre-Assembled Hardware
Supplied pre-assembled for quick fitting on site, reducing the number of loose parts installers need to manage during array build-out.
Grounding Compliance
Designed to maintain electrical continuity across the module frame and rail system, supporting the array's overall equipotential bonding.
Durable Anodised Finish
High-quality anodised aluminium construction resists corrosion and weathering, matching Schletter's long-term outdoor durability standards.
Compatible With Classic Rail Range
Designed to fit a wide range of Schletter Classic-profile mounting rails, giving continuity across mixed-generation Schletter installations.

Frequently Asked Questions
What is the difference between the Classic Wide clamp and the Rapid16 mid clamp?
The Classic Wide clamp is designed for Schletter's Classic-profile rail system and uses a traditional bolt-through fixing, while the Rapid16 range clicks into an 8mm KlickNut channel. Confirm which rail profile you are using before ordering clamps, as the two ranges are not directly interchangeable.
Can this clamp be used for both portrait and landscape module layouts?
Yes — the Mid Clamp Classic Wide supports both vertical and horizontal module mounting from the same part.
What module frame thicknesses does this clamp suit?
It is designed for framed modules with a frame height of 30 to 40mm. For thicker frames, check Schletter's wider clamp range before ordering.
Is this clamp pre-assembled or supplied as separate parts?
It is supplied pre-assembled, so the fixing hardware is already fitted to the clamp body ahead of installation.
Does this clamp support the array's earthing requirements?
Yes, it is designed to maintain electrical continuity across the module frame and rail as part of the array's overall equipotential bonding, in line with standard PV earthing practice.
