The Closer Pets Dog Door 216 is the ideal solution to give your dog free access to the house and outside without the door having to remain open all the time. Your dog can easily use the door independently. Thanks to the draft strip, it provides good insulation, and the practical left and right lock ensures that the flap stays securely closed. Suitable for doors up to 50 mm thick and dogs with a shoulder height of up to 63 cm. Dimensions: 44 x 36.5 x 4.5 cm.
