Ply Gem mounts and blocks create a smooth, stable surface for installing accessories on your home — from lights and doorbells to electrical outlets, water faucets and more. Constructed from high-performance polymers, our mounting blocks withstand extreme weather and hold their color for the life of your home. Most Ply Gem mounts feature a two-piece design that adjusts for easy installation over all types of siding.
Ply Gem’s universal mounting blocks are ideal for installing large items such as lighting fixtures, house numbers and mailboxes. The picture-frame design adds interest and lends a finished touch. You can choose from several sizes and styles, including square and rectangle shapes with gently rounded and scroll-cut corners.
Ply Gem’s one-piece surface mounts are designed for mounting small light fixtures, water faucets and other accessories to vinyl and aluminum siding. Available in two shapes — square and octagonal, the mounts look like wood, come in dozens of colors, and blend in well with your siding. Best of all, Ply Gem surface mounts are made of easy-to-care-for vinyl.
For doorbells, outlets, meters and other electrical components, Ply Gem offers electrical blocks in a variety of styles, from large to small. Listed by Underwriters Laboratories, Ply Gem’s UL® Mounting Block includes a weather-safe electrical box housing. Our split recessed J-Block design® can be installed without removing the electrical outlet.
