The Libec ALX S4 is the perfect slider shooting with a smooth and delicate controllability. ALX S4 allows you to slide your camera on a 75mm or flat base tripod or on a tabletop. The sliding range is 12" and payload is 15kg / 33 lb. when used on a tabletop. This is achieved by the eight high-performance ball bearings applied with a special grease, which are installed in the slider platform. The ball bearings are positioned efficiently on the rail top and at an angle on both sides, hugging the rail to prevent wobbling during operation. The spring-equipped friction knob enables precise weight adjustment for a smooth sliding movement. The friction knob allows you to adjust sliding tension, and a brake knob sets the sliding rail in one place. Using the supplied hexagon wrench, pushing force of the ball bearing against the rail can be easily adjusted.
A dual base tripod mount adapter, featuring a 75mm ball base design with a flat bottom, allows direct compatibility with the ALX T tripod as well as other flat base tripods. A bubble level conveniently sticks out on the side for easy leveling. 1/4"-20 and 3/8"-16 threads are available on the top ends for attaching articulating arms with lights and other gear. Rosette adapters are available on both sides for attaching rosette accessories. If you'll be using the slider on the ground or tabletop, you'll be able to adjust the height of the feet on either side if necessary. The feet simply screw in or out to be adjusted, and are tightened in position by knobs above them. Slider has collapsible tabletop legs for easy setup and storage.
All components are modular allowing users to have multi style configurations for any shooting environment. The ALX SP slider platform has a 3/8"-16 threaded mounting stud, which directly supports the flat bottom of the dual base ALX H head. Adding an extra ALX H Head allows users to pan, tilt, and slide along the rail. The rail length is adjustable thanks to its detachable design. The rail can be easily detached and replaced with slider rails ALX SR8 or ALX SR12 by simply removing the leg lock knobs. Includes Padded Carrying Case with strap, tripod mount adapter and bowl clamp for flat base / 75mm ball diameter tripods, and a maintenance kit for longevity.
