Model C911SD-18 is designed for raccoon, woodchuck and similar size animals. It weighs 13 lbs, is constructed of 1/2″ x 1″ wire mesh throughout the trap and measures 18L x 9W x 11H. This single door trap is strong, reliable, durable, and requires little maintenance. It features super strong coil springs that power the trap door. The door locks into place which prevents animals from escaping, even if the trap is rolled over or flipped completely upside down. This trap is triggered by a swing bar wire trigger mechanism which allows you to capture the most trap shy animals and does not have a trip pan for animals to avoid. All Comstock Series Traps are made to order and manufactured on a first in first out basis. Please allow additional processing time for this item to ship.
