Mounting rails and profiles for PV mounting are made of aluminium. You can use black anodised mounting profiles to install black solar modules with matching colours. ALTEC mounting rails have a slot width of 22.4 mm to accommodate the hammer-head bolts. This means that the rails can be fixed to the roof hooks or a cross-connection can be installed. All pre-assembled ALTEC PV module clamps fit these profile rails. Rails can be sent in 6 metre lengths or cut to the required size.
