The Schletter Mid Clamp Rapid16 is a click-in module clamp for framed solar panels with frame heights of 30-40mm, part of Schletter's Rapid16 family designed for fast, tool-light installation on any Schletter module-bearing rail fitted with an 8mm KlickNut channel.
Rather than a separate bolt-on bracket, the clamp simply clicks into the rail and is secured with a single pre-fitted Torx screw, cutting the number of loose fasteners on site. An integrated grounding pin bites into the module frame on installation, providing equipotential bonding without a separate earthing cable at every clamp position.

Key Features
Click-In Fitting
The clamp body clicks directly into the 8mm KlickNut channel on Schletter Solo, Rapid16-compatible and other module-bearing rails, positioning it accurately before the screw is tightened.
Integrated Grounding Pin
A grounding pin is built into every clamp, penetrating the module frame's anodised layer to maintain electrical continuity across the array without extra earthing hardware.
Portrait & Landscape Mounting
The click-in component rotates, so this mid clamp can secure modules in both vertical (portrait) and horizontal (landscape) orientation from the same part.
Pre-Assembled Torx Screw
Supplied with an M8 Torx (T40) screw with under-head serration and anti-friction coating pre-fitted, reducing loose parts and speeding up on-site assembly.
Corrosion-Resistant Finish
Manufactured from anodised aluminium, available in natural silver or black anodised finish to match silver or all-black module frames.
General Building Approval
Covered by German general building approval Z-14.4-631, giving installers a certified basis for structural sign-off on UK and European projects.

Can I use this clamp on a mix of black and silver-framed modules?
Yes — both finishes fit identically. Choose the finish that best matches your module frame colour for a consistent visual result; the clamping performance and dimensions are the same across both.
Does this clamp work for both portrait and landscape module orientation?
Yes. The click-in element inside the mid clamp can be rotated on site, so the same part supports modules mounted vertically or horizontally — you do not need a different clamp for each orientation.
Do I need a separate earthing cable at each clamp?
No. Every Rapid16 clamp has a grounding pin built in, which bites into the module frame's surface as the clamp is tightened, maintaining equipotential bonding across the array without additional earth straps at each clamp point.
What rail systems is this Mid Clamp Rapid16 compatible with?
It fits any Schletter module-bearing rail profile that has the standard 8mm KlickNut channel, including the Solo, Solo05 and related Schletter rail ranges used in UK pitched and flat roof installations.
What tool do I need to tighten the clamp?
A T40 Torx driver or bit. The M8 screw is supplied pre-fitted in the clamp body, so no loose fixings need to be located on site.
