The Heath MP15 Purple Martin House Pole is a 15-foot telescoping support system designed for Heath Purple Martin houses, accommodating both wood and aluminum models. Constructed from heavy-duty, rust-resistant galvanized steel, this four-piece pole features a graduating diameter for enhanced stability: 1-9/16 inches at the bottom, 1-1/2 inches for the second section, 1-3/8 inches for the third, and 1-1/4 inches at the top. The pole can be easily raised or lowered and locked into position using the integrated Heath keylock system. It typically includes a ground sleeve for installation, which is recommended to be cemented into the ground for maximum stability. The system is designed to support a maximum weight of 25 pounds, suitable for various birdhouse and gourd setups.
