Berger AP Snow Guards are non-penetrating devices which have been engineered specifically for use with the more popular structural and non-structural preformed and architectural metal roof systems. They are produced in cast aluminum. They are secured without glues or sealants, and utilize custom milled stainless steel set screws to clamp them in place. The wide, deep blade design makes it particularly effective in retaining snow with the higher seams and wider panel widths common in preformed architectural roofing. The attachment of the AP Snow Guard does not restrict thermal movement, and the deep throat permits it to be secured directly without damaging caps or compressing internal gasketing or sealant pockets.
