Model GT610A is our Gravity Series live trap designed for small to average size dogs and similar sized animals. This revolutionary new Tomahawk Live Trap design features an automatically setting door, instant locking latch and is 100% gravity operated. The trap sets completely by itself when you lift the door open. The instant locking latch on the trap eliminates any chance of the door bouncing or being lifted from the inside and safely keeps trapped dogs inside. Elimination of the door bounce makes it virtually impossible for dogs to push their way out and escape because the door instantly locks when it closes with no bounce delay. This trap measures 48L x 20W x 26H and is constructed from 1" x 2" - 12 gauge galvanized wire mesh. This trap also features an easy release rear access door for easy baiting and transfer of animals.
