A mounting and attachment system, which mounts a continuous snow rail for snow protection above the seams of a metal roof and also attaches lower members or snow flags between the seams to stop the snow from sliding under the seam. This system reduces the requirement for holes and threaded holes in the mounting block. The mounting block has a slot which runs therethrough to fit over a raised seam. This slot can have parallel walls or can be shaped to match a particular seam. This block also has slots or linear indentations on the sides or ends in a direction perpendicular or parallel to the slot for the seam. A snow rail long enough to connect two or more of the seam-mounted blocks together. Finally, a top rail may be secured parallel to the seam and mounted on two or more seam mounted blocks.

I claim: 1. A snow brake and mounting system for metal roofs with parallel raised metal seams, said system having:a first mounting block attached to a first raised metal seam,a second mounting block attached to a second raised metal seam located in a spaced relationship to said first seam,a snow rail with one portion connected to said first mounting block and another portion connected to said second mounting block, the improvement wherein:said first and second mounting blocks comprise:a base with bottom and top surfaces, the base having a longitudinally extending body with first and second longitudinal end surfaces, a seam-receiving groove extending upward from the bottom surface toward the top surface and terminating at a location spaced from said top surface, said groove extending through the first and second end surfaces, said groove receiving a respective raised metal seam, said groove dividing said base into first and second opposite side portions connected at the top, said first side portion having at least one hole extending transversely through said first side portion for receiving a set screw, said second side portion being shaped to interlock with said raised metal seam to secure said mounting block to said raised metal seam when said set screw is tightened against said seam,said first and second longitudinal end surfaces defining respective grooves, said grooves being positioned perpendicular to said seam receiving groove and positioned above the top of said raised seam,said snow rail further comprises a longitudinal groove that is configured to interlock with said grooves on said first and second end surfaces of said base to connect said snow rail to said first and second mounting blocks, and means on said system for mounting another device.
