DOMED - Concave aluminum snap-type plate has single clip riveted across full diameter. Snaps to the ring at two contact points. Plate is 4-3/4" dia.
RECESSED - Recessed center and flanged-edge design will not creep off center due to vibration in propwash areas. 4-3/4" dia. x .020 aluminum. Will not twist or vibrate.
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.
