2.56"(63mm) Stiffener Loc Coupler

2.56″ Tube Coupler Stiffener – 5.5″ long.

Stiffy heavy duty tube coupler stiffiners feature a deep spiral groove for maximum epoxy adhesion. These super heavy duty wall stiffeners are designed to be epoxied inside of our standard tube couplers to greaty increase their lateral strength. Snapping off a payload at the joint under high speed stress (as occurs when flying at or near Mach speeds) is not a worry when you fly with a Stiffy.
