K2 Systems

The K2 Clamp MC Black is a universal center clamp for mounting framed solar panels on K2 mounting rails. With a flexible clamping range of 25 to 40 mm, it accommodates the majority of standard module frame heights on the market. The elegant, black anodized finish ensures a visually appealing integration into modern PV systems.

NOTE: The clamp comes with the required “MK2” insert nut and screw. Installation is accomplished by simply snapping it into the rail chamber of the K2 profiles, which significantly reduces installation time on the roof.

Maximum flexibility: Thanks to OneMid technology, there is no need to change clamps when dealing with different module thicknesses within the specified range. This greatly simplifies material planning and inventory management. The high-quality anodized finish also effectively protects the component from the elements.

Advantages

Universal Clamping Range

Thanks to its adjustability from 25 to 40 mm, the clamp adapts flexibly to nearly all standard module frame heights.

Discreet Aesthetics

The black anodized surface blends harmoniously with the appearance of dark PV modules and mounting rails.

Quick-Click Installation

The “MK2” system allows for easy snapping into place at any point along the rail without having to slide it in from the side.

Maximum system stability

As an essential component of the K2 system, the Clamp MC meets the strictest quality standards and, thanks to its precise manufacturing, provides maximum stability for your PV system.

Special Features

Easy handling

The clamp stays in position once snapped into place, which facilitates one-handed installation of the modules on sloped roofs.

Durable Materials

The combination of aluminum and stainless steel components guarantees a permanently corrosion-free connection.
