All prices are for 1 Coupler Plate

Coupler Plate fit may vary due to .3 mm in tube tolerance

G10 fiberglass Coupler Plates (also known as airframe bulkheads) are precision cut to match Mach 1 tubing, but will work for other manufacturer's tubing (may require light sanding). Each plate has a small mark in the middle to identify true center. 

These Coupler Plates fit inside the airframe and butt against a coupler tube.
