Wehr's 5" Spring Dual Bearing Slider - 2" Longer - (Fine)
A linear ball shaft bearing instead of bronze bushing is used along with a shaft stabilizing internal piston for the smoothest and most stable slider on the market. The spring cup opposite the adjusting nut is quickly removed with a clip, so you don’t have to unscrew the nut to remove the spring. Also a four position locking mechanism for fine tuning. There's a Torrington bearing on the adjuster nut so you can adjust it easily and so the spring works freely throughout its travel.
Sliders are 24" (WEHWM251) and 26" (WEHWM251-2)
