K2 Systems 2004146 Universal Mid Clamp for PV Modules 25-40 mm, Silver Anodized

Unlike fixed-width clamps that force installers to stock multiple sizes, the K2 Systems 2004146 Universal Mid Clamp self-adjusts to grip any framed PV module between 25 and 40 mm thick. This single component covers nearly the entire residential and commercial range, eliminating guesswork and simplifying procurement. Pre-assembled with an M8 stainless steel screw and K2 Climber T-bolt, it drops straight into K2 mounting rails and tightens from above with a standard hex key—no loose parts, no fumbling on the roof, no second trips to the van.

Highlights

• Universal fit: accepts module frame heights from 25 to 40 mm, reducing inventory and simplifying procurement.
• Pre-assembled design: clamp body, screw, and K2 Climber arrive as one unit—ready for top-down installation.
• Marine-grade corrosion resistance: anodized aluminum body (EN AW-6063 T66) and stainless steel A2 hardware withstand decades of weather exposure.
• TÜV Rheinland certified for mechanical safety and long-term reliability in PV mounting systems.
• Optimized for K2 SolidRail, SpeedRail, and MiniRail—but compatible with any standard 40 mm rail channel.

In daily use

On a pitched roof or open field, the mid clamp sits between two modules and applies even pressure across both frame edges. The self-adjusting geometry automatically centers the clamp on frames from 25 to 40 mm, so you never need to swap jaws or add shims. A single M8 flange nut with a recommended torque of 10 Nm secures the assembly, while the hexagon socket head allows quick tightening from above. The anodized finish and stainless steel hardware ensure long-term performance even in harsh environments.
