Upgrade your home’s exterior lighting with this 4-pack of octagonal vertical siding mounting blocks, each featuring a built-in electrical box for effortless fixture installation. Crafted from high-quality white ABS plastic, these blocks measure 6.53 inches by 6.53 inches—perfectly sized for 1/2-inch lap siding. The textured surface accepts paint easily, allowing you to match your siding color or keep the natural white finish for a seamless blend. Designed for durability, the material resists moisture, UV rays, and temperature extremes, ensuring reliable performance year after year. Installation is straightforward: drill a hole through the siding lap, route the wire, remove the knock-out from the electrical box, insert the included cable connector, and secure the block with the provided screws. Then attach your exterior light fixture for a polished, professional result. This versatile kit works on vinyl siding, T-111, HardiePlank lap siding, and other flat surfaces, making it ideal for adding porch lights, wall lamps, or security fixtures. Each package contains four mounting blocks with electrical boxes, four cable connectors, and eight mounting screws—enough supplies for multiple projects. For best results, caulk the top edge of the block if it doesn’t perfectly match your siding profile, and leave the bottom drainage hole open to prevent water accumulation. Whether you’re a DIY enthusiast or a professional installer, this siding mounting block set simplifies outdoor lighting upgrades while delivering a clean, weather-resistant finish.
