The Tomahawk Model 109SS-F is our Professional Series raccoon, woodchuck sized trap featuring a flush mount trap door. Flush mount doors allow for positive sets which means when the trap is armed the door does not extend out past the trap frame. This allows the trap to be set flush against den openings on vertical surfaces. When the target animal exits its den, it must enter the trap. This trap measures 42L x 12W x 12H and weighs 16 lbs. It is constructed from 1/2 x 1 - 14 gauge galvanized wire mesh for superior strength and durability.
