Easily mount your Purple Martin houses on a wooden post with the S&K Manufacturing WPA Wood Pole Adapter—a versatile, durable solution that allows you to display your existing S&K martin house without the need for a traditional triangular pole. This smartly engineered adapter system provides strength, flexibility, and ease of use, making it an essential accessory for martin enthusiasts looking to customize their housing setup. The two-piece adapter includes a wide back plate and a triangular extension sleeve that connect quickly and securely. The 4.125-inch flat mounting plate attaches directly to any standard 4x4 wooden post, fence, or vertical surface, giving you freedom to select the perfect location for your martin colony. Once installed, the triangular sleeve slides through the center of compatible S&K martin houses—such as the S&K Heavenly Haven, Great Eight, and American Barn models—and snaps into place using a series of push-button connectors for stability and alignment. Each button on the adapter aligns with the house's existing floors, keeping the structure level and secure while allowing for easy removal when it's time for seasonal maintenance. The snap-fit design eliminates the need for complex hardware, ensuring a snug and wobble-free connection between the house and the post. Crafted from heavy-duty black plastic, this adapter is designed to withstand years of exposure to sun, wind, and rain without rusting or warping. Its modular shape works with a variety of post dimensions, offering versatility for different backyard layouts or martin housing displays. Perfect for both new and experienced martin landlords, the S&K WPA Wood Pole Adapter lets you repurpose existing posts while maintaining the reliable support your birds need. It's also a great option for users who want to install their martin houses in locations where triangular poles are impractical, such as beside decks, patios, or near existing landscaping. As with all S&K products, this adapter is proudly made in the USA and built with precision and durability in mind—ensuring your martin housing remains secure and functional for years to come.
