Very good high quality cover. The spring is strong and holds the cover firmly. The ring is easy to install.
everything arrived in a couple of days and the product was beautiful just what I wanted
The products are great, the assistance was even better.
I had to add an inspection hole in my already fabric covered fuselage. These rings and covers are perfect.
Great just what I needed !!!
Received in a timely manner
I have not installed these as yet however they seem to be just what the Dr. ordered. Also the inspection rings.
