The Lumax adjustable clamp is specifically designed to secure the outer edge of the final panel in a row to the mounting rail. Its adjustable profile allows a single clamp model to accommodate a range of panel frame thicknesses, ensuring a secure grip at the termination points of the array.
This clamp works as part of a full mounting system: once the rail (or roof bracket) is installed, the end clamp is positioned at the ends of the panel row, tightened down so the clamp grips the panel frame and presses it against the rail (or rail slot), ensuring the panel stays fixed, aligned, and secure even under wind, vibration, or thermal stress.
Adjustable end clamps are essential components in both residential and commercial rooftop solar installations, and are compatible with various roof types (metal roofs, IBR/corrugated roofs with rails, flat roofs, etc.), depending on the rest of the mounting hardware configuration.
Material: Aluminium alloy with stainless steel hardware
Surface finish: Natural anodised for corrosion and weather resistance
Compatible panel frame: Adjustable to accommodate frames from 30 mm to 50 mm, covering most modules.
Hardware: Supplied with stainless steel M8 bolts for rail attachment
The adjustable range allows a single part to be used with various panel brands and models.
The clamp provides a firm grip on the outer edge of the end panel. This prevents movement from wind uplift or vibration and protects the modules from damage that could lead to performance degradation over time.
Anodised aluminium construction paired with stainless steel hardware ensures the component meets its expected 25+ year service life without failure, even in coastal regions or areas with harsh weather.
Using a single, universal clamp model for various panel types speeds up the installation process. It also reduces the risk of ordering incorrect parts, preventing costly project delays and return trips to the site.
By reducing the number of distinct clamp SKUs needed in inventory, this solution simplifies logistics and can lower overall supply costs, translating to more competitive project bids and higher profit margins.
