Zbeam® universal speaker rigging beams drastically reduce the time it takes to complete your flown speaker installation or live set up, and they work with almost every flyable speaker on the market. The Zbeam has a heavy duty axle and friction bearing which holds a pan angle after a speaker has been aimed. See our support document, “What is a Zbeam?” All Zbeams have a 10:1 design factor. Connections to the most common Zbeams are made with 5/16 inch or 8mm shackles. For serviceable installed line arrays or other clusters raised and lowered on a single electric chain hoist, see our Motor Zbeam® products (product family MZB).
