Model 603F is an Original Series flush mount live trap for squirrels, rats, muskrats and similar size animals. It measures 20L x 6W x 6H, is constructed of 1″ x 1″ – 14 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 a rear access door for easy baiting and removal of animals.
