Hyper-Glide replaces any 3/8" slide, carrying cables under the rod. Click-n-shoot installation locks cables into our Hyper-Glide cradle while the body glides over the rod on our ultra low-friction wheel. The Hyper-Glide cradle's flared cable-ports and super-slick, super-quiet material reduce cable wear. This material is smoother and slicker than any other used on slides today. Combining our wheel and Hyper-Glide's cradle gives the lowest rod friction, the lowest cable wear and highest shooting consistency. Now with Silicone O-Ring! Weighs only 161.3 gr.
