The Sliding Arm II from Slik is a mini-boom extension arm that allows photographers access to multiple unique angles and vantage points when added to an existing tripod leg set. The arm tube is connected to a fulcrum that allows it to swing, shift, tilt, and move freely in any direction. Extending up to 19.5" out over the legs of a tripod allows for vertical, lateral perspectives that are useful for copy stand or macro photography applications. The extension tube arm features a 50mm scale, making it easy to determine placement, and also incorporates a counterweight hook for stability as the arm is extended out from the tripod. The sliding arm features knob threads that lock into place at multiple positions, and a 1/4"-20 head mounting screw that is compatible with most tripod heads.
