Decormax Heavy Duty Dog Door for Wall, Energy Efficient Doggie Door with Aluminum Frame, Telescoping Tunnel, Double Magnetic Flaps and Two Sliding Lock Panels, Easy to Install, Black, X-Large

Door is good but the tunnel is still to short to go through a wall (max 8” when extended ) standard British wall 10” !! However have fitted and made to work.Need to know how you can purchase spare door flaps and screws. Doesn’t seem to have an option to contact sellerUPDATEI have taken the panels out to clean, the screws to hold the panels in are a joke. I have now lost one screw and can’t find anywhere to get a replacement. On the other panel inside one the bar has come off i can’t reattach it.For the money and the fact they are recommended for big dogs the build quality is shocking and no support or anywhere to get replacements. I have had to just put the outer shutters on it otherwise there is a huge hole in the wall, so can’t even use the dog door.Need the supplier to get in touch to provide support and spaer parts otherwise the review stands and wouldn’t advise getting one at all
