The Tomahawk Model 602SS-F is our Professional Series chipmunk and squirrel sized trap featuring a flush mount trap door and easy release rear 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 19L x 5W x 5H and weighs 3 lbs. It is constructed from ½ x 1 - 14 gauge galvanized wire mesh for superior strength and durability.
