Glass reinforced polycarbonate fitting at the leg juncture uses a metal clamp over the fitting to minimize over-tightening and breakage. The stands raise and lower with the turn of a redesigned knob, locking tightly for secure support. Metal clamps over plastic fittings minimize over-tightening and breakage. The footcaps are held in place by both internal and external friction so they stay on gig after gig. The Ultimate Support TS-90B Series stands also feature a new connector tube, which telescopes up to accommodate 1-3/8 in. speaker sockets and down for 1-1/2 in. sockets. It locks firmly into desired position and minimizes the need for adapters. A telescoping tube lock prevents accidentally pulling out the center tube.
