Dynamic Fastener’s Dyna-Guard snow retention system for standing seam roof systems is an 8-foot-long extruded aluminum stick with a T-shape profile. Dyna-Guard is installed by attaching clamps or brackets to a metal roof and bolting the system to the clamps or brackets. Seven Dyna-Clamps with round-point set-screws and two models of Sno-Dams are offered. Sno- Dams attach to the back of Dyna-Guard and inhibit snow and ice from sliding under it. A 2-inch-wide painted strip of metal roof material is inserted in Dyna-Guard for aesthetics.
