Welded stainless steel spinnaker pole sliders are constructed with formed rings that are heliarc welded to the slide. Schaefer designed these sliders to bend under conditions of extreme force rather than failing suddenly.Unique, easy-sliding polyethylene liners provide a low-friction solution to mounting on your existing T-track. They glide virtually without detectable friction, yet can handle high tension or compressiion loads without deformation.
