This vinyl siding mounting block gives outdoor light fixtures and outlets a clean, weatherproof point of attachment on your home's exterior. Made from UV-resistant, heavy-duty PVC, it resists warping and cracking outdoors, and the paintable white surface blends with most vinyl siding. Integrated drainage holes help prevent water buildup, though the top of the electrical box should stay sealed while the bottom drainage hole remains open. The block is sized for 1/2 inch lap siding, including T-111 and HardiePlank profiles, and its snug fit reduces the need for extra caulking around uneven surfaces. Each kit includes the mounting block with a built-in electrical box, eight stainless steel screws, and two cable connectors for a lightweight, complete installation.
