With only two screws, the bracket is clamped over the metal seam, the sinusoidal protrusion of the bracket enables a good grip without damaging the roof sheet. For mounting on sloping roofs, the bracket can be angled and thus mounted perpendicularly on roofs with up to a 60° slope. By loosening one screw the angle can be changed quickly, all screws are adjusted with a nut driver and socket size 18 just like other GuardLite™ mounts.
