Pro-100 Snow Guard Assembly includes a 1-inch gusset that reinforces the shoe, which makes this snow guard 5 times stronger than traditional residential snow guards.
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 slate or shingle, engage a nail with one of the conveniently placed slots and pull to fully secure the bar.
