Model 603.5F is an Original Series flush mount live trap for squirrels, rats, muskrats, other rodents and similar size animals. It measures 20L x 6W x 6H, is constructed of 1/2" x 1" - 16 gauge, galvanized steel and weighs approximately 4 lbs. This trap features a flush mount trap door which means the trap door does not extend past the frame of the trap when it is set. This allows for flush placement against structures when dealing with an animal that has created an entry/exit hole in a wall. It also features tight mesh pattern throughout the trap making it a excellent trap for all species of squirrel. This trap also has an easy release sliding door for easy baiting and removal of animals.
