In the installation of photovoltaic mounting on tin roofs, L feet are one of the most widely used solar accessories. Birstar L-foot system is therefore one of the best-selling products

Installation: SunLock L-feet is first fixed in a straight line along the length of the proposed rail location (in the purlins beneath the roof material), then the rail is fixed to the upright tabs on each L-Foot. An elongated rail fixing hole in the upright tabs ensures any undulations in the roof line are compensated out of the frame, therefore, eliminating physical stress on the delicate solar panels. Each L-Foot is supplied with a general-purpose roofing screw for fixing to the timber of steel bearers.
