The Catwalk Designer Glass Fitting Cat Door and
The Catwalk Designer "Maxi" Glass Fitting Cat Door
are both available in white frame and a very unobtrusive clear frame. They are designed to be installed in glass, single or double glazed, as well as other thin materials including plywood, Lexan or screen.
A circular 9.6" hole is required for installation of the regular size-6 3/4" x 6 1/4"-cat flap and the thickness accommodated is up to 1/4" with the screws provided or 1/2" maximum if you get longer screws.
For the Maxi size a circular cut out of 10.5" is required and the flap opening is increased to 71/4" x 7 11/16". Importantly, the adjustment range is extended to 1 1/16" which can be very important if you install through a double glazed unit thicker than 1/2".
Remember - You cannot cut tempered glass. So if you're not sure, have a professional glazier provide you with a new piece with the hole pre-cut. If you try to cut tempered, it will shatter. For a double-glazed situation, you can be pretty sure the glass is tempered and you'll need to have a glass shop make you a new insulated glass unit with the circular cut out.
A 4-way lock is included on both doors.
Screws provided are stainless (a big plus) and are not accessible from the outside.
The frames are self-draining for water build up from condensation.
What sets these "glass-fitting" cat flap apart from others is the use of UV stabilized, Makrolon which is a high-impact polycarbonate and very strong. No more broken flaps.
The larger, "Maxi" cat flap includes a brush-type weather seal while the regular sized cat flap does not. We think this seal is important and would not recommend the smaller size for 4-season use.
