Libec ALX S4 Slider (15.5")

The Libec ALX S4 is a 15.5" long camera slider that features an integrated 75mm ball base with a flat bottom, allowing it to be mounted directly to 75mm bowl fluid heads as well as flat-base heads. When used on tabletop or flat surface using, the slider has a maximum load capacity of 33 lb. For smooth and wobble-free operation, the carriage features eight roller bearings positioned on the rail top and along the sides at angles. A spring-loaded friction knob allows you to adjust slide tension, while a brake knob will lock the carriage in place at any point on the rails. Using a supplied hexagon wrench, you can adjust the pushing force that the ball bearing exerts on the rail.
