The Gold-N-Rods are lightweight and very strong. The spline design eliminates binding and friction, and the non-metal construction prevents radio interference. These are very easy to install and easy to adjust, and they also utilize temperature compensated materials to minimize thermal expansion. These are for large models or high strength applications. They use 4-40 hardware and are for uses where turns are slight or the length is over 48". The test strength is 80 lbs. and the clevises are not included. The overall length is 36". The stock number for the clevises is SULQ3126. They come 4/pkg and the sheath color is black. WAJ 1/12/92
