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
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
