Model VPS-CT108F is The Large, Flush Mount Critter trap by Viking Product Supply is a professional quality live trap for raccoon, opossum, woodchuck and similar sized animals. This trap is constructed with a quarter inch steel rod frame and features a locking, spring loaded, thick solid steel door. The door on this trap is also flush mount meaning that the door does not extend past the front of the trap when the trap is set. This allows for flush trap placement against entry holes on structures or fencing. The frame of this trap is wrapped in a tight 1/2" x 1" wire mesh to prevent animals from reaching in or out. This is a very easy to set and easy to use trap for beginners and professionals alike. Simply lift the door and push a trigger rod under the door to set. This trap is triggered when an animal steps on the trip plate which releases the door from the trigger rod and traps the animal safely inside. This trap measures 36" long x 10" wide x 12" tall. It is an excellent all around trap for many large critters.
