|Clear Plastic rings, 4-5/8" O.D. x 3-1/2" I.D. x .050" thick, molded from virgin cellulose acetate butyrate resin. To be cemented to fabric as inspection plate retainer|
Very good high quality ring.
I had to add an inspection hole in my already fabric covered fuselage. These rings and covers are perfect.
Just what I ordered
They do the job very well . Just glue them on and cut the hole out .
You would use the fabric glue compatible with the covering system you have on the aircraft. Poly tak or super seam for example. We don't believe you have to sand the fabric.
