Fastensol Standing Seam Clamp Roof Hook Supply

These standing seam roof hooks can be used to secure the mounting rails to the standing seams on a roof, such as a butler roof.

Simply use a 13mm spanner to tighten the bolts on the hook and it will clamp onto the standing seam. You can then attach whatever you wish onto the 11mm slot on the top of the clamp. Needs an L bracket or cross connect to attach to the rail.
