Model C911TD is designed for raccoon, armadillos, skunks, wood chucks, fisher, opossum and similar size animals. This is a heavy duty professional trap with one trap door. This trap is strong, reliable, durable, and requires little maintenance. It features super strong coil springs that power the trap door. The rear slider door pulls straight up from the top with a handle. This door allows easy transfer of the captured live animal into an adjacent holding cage. There is a locking device that secures the rear slider door in place. Both doors lock 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.
