LOC Precision - 5.38" Tube Coupler Stiffener

5.38" Tube Coupler Stiffener

NOTE: Stiffys are not compatible with phenolic couplers. 

Stiffy heavy duty tube coupler stiffeners feature a deep spirsl groove for maximum epoxy adhesion. These super heavy duty wall stiffeners are designed to be epoxied inside of our standard tube couplers to greatly 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.

NOTE: TC-5.38 is REQUIRED to use this device.
