TeleLock® series speaker poles from ultimate support are extraordinarily strong, yet lightweight thanks to their oversized, thick-walled aluminum tubing. They’re everything you’d expect from an Ultimate Support speaker stand. Strong, sturdy, lightweight, 100% field serviceable and easy to set up and take down. The Tele-Lock technology securely grips the telescoping tube in place as you set its height. The new SP-90 speaker poles feature an expanding cylinder system that will firmly fit multiple speaker sockets from 1-3/8” to 1-1/2” diameter. Using a 2mm hex wrench, the adapter can also be removed to provide standard M20 threading, allowing your SP-90 speaker pole to be a truly universal solution.
