Aluminum alloy adjustable end clamps for solar panel mounting. Pack of 8. Key benefits Durable and corrosion resistant: made from aluminum alloy with anodic oxidation treatment on the surface for long service life in outdoor conditions. Secure hold on uneven surfaces: designed groove strips help clamp firmly to most solar panel frames and accommodate minor surface irregularities. Easy alignment and installation: predrilled holes ensure correct position and direction; works with standard mounting bolts for quick setups. Adjustable height options: available in multiple heights to match a range of panel frame thicknesses and rail systems. Features and specifications Material: Aluminum alloy with anodic oxidation surface treatment Height options: 30 mm (1.18 inch), 35 mm (1.38 inch), 40 mm (1.57 inch), 45 mm (1.77 inch) Function: end clamp for connecting and fixing solar panels to mounting rails; secures panel ends and maintains alignment Compatibility: suitable for most photovoltaic panel frames and standard rooftop or rail mounting systems Package contents: 8 end clamps Typical applications Residential rooftop installations where panels need firm end clamping and precise alignment Marine or boat installations where uneven surfaces and corrosion resistance are important Wall mounted, garage roof, or other outdoor structure solar arrays requiring adjustable end clamps Installation notes Use compatible mounting bolts through the predrilled holes to secure the clamp to rails Verify chosen clamp height matches panel frame thickness before installation Allow a 1 to 2 cm tolerance for manual measurement and expect slight color variation due to monitor differences These end clamps provide a straightforward, adaptable solution for securing solar panels in a variety of outdoor mounting scenarios.
