1515 Conformal Rail Button Backplate Mount
 

This is a continuation from my 1010 Conformal Rail Button Backplate Mount design that has been upgraded to 1515 rail buttons for use on 1515 launch rails. It's purpose is to provide a way to mount the rail button nut so that it does not interfere with the operation of the recovery system.

This place where the nut sits is designed to fit the 1/4"-20 nut.

There are two designs:
A) This will fit 6 inch airframe tubing that has an ID of 6.0 inches (152.4mm).
B) This will fit 6 inch coupler tubing that has an ID of 5.775 inches (146.69mm)
