Adjustable Middle Clamp 30-45mm | Solar Panel Mounting Rails

An adjustable aluminium middle clamp for securing two adjacent solar panels to mounting rails at their shared inner edge. It fits panel frames from 30mm to 45mm and comes with a stainless steel Allen bolt. Sold per unit.

Key features

• Adjustable range, 30mm to 45mm panel frame thickness
• Fit, works with standard aluminium-framed solar panels within this range
• Clamping design, symmetrical profile applies equal force to both adjacent panels
• Minimum quantity, at least 2 clamps required between any two panels
• Hardware included, stainless steel A2 Allen bolt and washer

Product overview

Middle clamps sit between two adjacent panels in a row, securing both to the rail at their shared inner edges at the same time. The symmetrical clamping profile spreads the holding force evenly across both frames, so neither panel takes uneven load or distorts.

Because the clamp adjusts across the full 30mm to 45mm range, it suits most aluminium-framed PV modules on the market. Use at least two middle clamps between any pair of panels for a stable fixing.

Applications

• Residential and commercial rooftop solar PV installations
• Between adjacent panels in portrait or landscape rows
• Standard aluminium PV mounting rail systems

Installation notes

Fit by a qualified solar installer. Use a minimum of two middle clamps between each pair of adjacent panels, and apply the torque specified by the mounting system manufacturer. Check panel frame thickness before ordering.
