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.

The rivet spacing is a great improvement over the older inspection plates. These should stay in place much better because of the addirional clamping force since the rivets are spaced wider.

Right out of the box they fit great, had a good finish on them that was ready to prep and paint, and have a strong spring to keep them in place. After several flights the inspection plates havent moved a millimeter.

I wish the old style 2 cross clamping bars were still available. They are a pain to get on and off, but they stay on!

Poor quality mfr sharp sharp edges.inexpensive though
