Wickenkamp Model 50Live Cage Trap measures 15"H x 12"W x 36"L and is built TOUGH. The 12.5 gauge wire mesh makes for one of the sturdiest traps on the market, and will last for years. The door and trigger pan are both constructed of 0.25" steel rod and the door is gravity activated. There is a locking bar which slides downward once the door falls to secure the captured animal. Double wire at the rear of the trap adds further durability to the pan and baiting area.
