Street door for cats Trixie 3850 This model has a second hinged frame without a glass which covers the gap between the sash and the main frame and prevents the penetration of moisture wind and crawling insects. At the same time the frame is quite light so it does not complicate the opening of the sash during the passage of the animal. The additional frame and the flap are equipped with door closers and close completely quietly without cotton. A frame with a sash and a four-position handle for adjusting the operating mode is placed indoors. Bore dimensions: 157 x h160mm
