The outer and inner frame are simply screwed together from inside, clamping the window to the vehicle wall. The inner cassette is then fixed to the inner frame.

Please take care when measuring your current caravan window to ensure you order the correct item. If possible, you should check for sizes etched on your original window and also check the exact cut out size of aperture/hole. The listing measurements stated above are aperture sizes (actual sizes you would cut). Please ensure you have enough clearance both inside and outside of your vehicle for the window to fit by checking the Overall External Size given in the chart below.
