Max Flange

Currently my product offering is a set of fl**ges that would allow Avion owners, with the original 18" square openings to accommodate the original fans, to install and give them a 14" square opening that would accommodate mounting of modern Maxxair, Fantastic etc. fans.
The exterior fl**ge is made out of 6mm Ultra White Alupanel. It is a phenolic resin core sandwiched between two layers of aluminum that have been coated with white epoxy paint. It is 23 3/4" x 23 3/4" with 3" radius corners. The cutout is 14 1/8" x 14 1/8". The predrilled holes are 3/16" diameter, spaced about 1 7/8" apart, 1 1/4" in from the outside edge.
The inside fl**ge is made out of 3mm brushed aluminum Alupanel. Thinner phenolic core with brushed aluminum finish on the facing side. Same external dimensions and cutout but holes are 1/8" diameter and spaced about 3" apart.
I prepare them for shipping and include a 3 page set of tips and observations based on the ones I installed on our 1978 28M.
Price is $120.00 per set plus shipping which I determine based on your address when I drop it off at the UPS store. I send you a picture of the receipt and expect payment at that time using PayPal.
