Ultimate Support Systems TeleLock TS-90B Speaker Stand

The TeleLock TS-90B Speaker Stand collar has an internal, one-way friction mechanism with three settings. In the "RAISE" setting, the mechanism grips and holds the tube, allowing you to incrementally pull the center tube up to the required height. In the "LOWER" setting, TeleLock eases off and assists lowering the center tube. In the "LOCK" position, the telescoping tube stays in place allowing for easy removal of the speaker. This unique design reduces strain and adds safety.
