The Aero Utility Tray with Arm from Tether Tools is an ideal way to keep batteries, power packs or other equipment accessible on light stands, tripods or similar supports while eliminating clutter and freeing up floor space. The 11.5 x 8" aluminum table has two raised edges to prevent items from rolling and an integrated LAJO-4 ProBracket with 1/4"-20 and 3/8"-16 taps and a 5/8" receiver that accepts the included 5/8" reversible stud that comes with the 7" arm. The arm ends in a 5/8" hex stud meant for the Rock Solid Master Clamp or other accessory with a matching receiver. The bracket is machined to fit directly into an Arca-type quick release if desired. The non-reflective black tray and arm will support up to 35 lb.
