The Backstage Equipment Horizontal Monitor Cross Bar for Mag Senior Carts anchors to two 5/8' baby pins at each end of the cart, one on the U-handle and one on the nose. This allows you to mount multiple optional 'Slide-On' 5/8' baby pins to run along the length of the bar. Made of steel, the bar can support up to three optional 24' monitors side by side. The Monitor Horizontal Cross Bar can be offset by up to 9.75' towards the back or front of the cart by using two optional offset arms.
