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

Poor quality mfr sharp sharp edges.inexpensive though

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.

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!

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.
