Woodcraft frame sliders stand out in a market crowded with look-alike options. Our patent pending design features a universal slider puck that fits nearly all slider models. What makes the Woodcraft design unique is the perpendicular attachment bolt for the puck. Because we do not have to hollow out the center of the puck, we can leave the sliding surface of the puck solid. This provides 48% more plastic to slide on, dramatically improving puck life. The side mount also eliminates the hassle of trying to dig out a puck replacement bolt through a distorted hole.
