The Tomahawk External Chimney Trap is designed to fit over the chimney flue and is easily secured. It features two mounting flaps that can be used to secure the trap and cover larger openings to ensure the raccoon is directed into the trap. The trap is triggered when the raccoon exits the chimney, climbs up the trap, and pulls on the rear panel. This trap measures 36L x 12W x 12H" and is constructed of 1" x 1" – 12 gauge wire mesh frame with ¼" steel reinforcing rods for added strength. This trap also comes with a black powder coat finish.
