PD10R (Retrofit) Half Round Pad Style Snow Guard

PD10R (Retrofit) Half Round Pad Style Snow Guard

Alpine SnowGuards' PD10R is one of the their most sought after solutions for managing snow on existing natural slate roofing. A riveted clip and no fasteners needed make the PD10R easy to install and secure. Its holding power was precision-engineered to lend a blend of strength, durability, functionality, and attractiveness. The PD10 is an iteration of the first snow guard Alpine’s company president designed decades ago. Today, it’s a widely used snow management device on historic, commercial and residential construction projects. A fleur-de-lis embellishment can also be requested to create an historic look.
