The Lifetime Tool SquareLock Snow Guard is a heavy-duty, non-piercing snow retention device specifically engineered for double lock standing seam metal roofing panels. Cast from a certified Almag 35 aluminum-magnesium alloy, it offers exceptional strength and corrosion resistance. The patented design features two stainless steel set screws that, when tightened, force the seam metal into a recessed square pocket in the casting, creating a secure lock in all directions without penetrating the panel. Tested to rigorous standards, the SquareLock provides unmatched strength and durability to prevent dangerous snow slides, protecting property and people below. Available in sizes to fit common seam thicknesses.
