The #100 Pro Style Snow Guard Assembly is just the like the #100 version but includes a 1 inch gusset that reinforces the shoe to provide extra support. The Pro 100 has been tested to withstand a 300-pound point load at any location when applied to the gusset side of the shoe.
Simply insert the slotted bar under the roofing material, engage a nail with one of the conveniently placed slots and pull to fully secure the bar. The #100 Pro snow guard provides for a fast and easy installation and is ideal for retrofit or new construction applications.
