On Stage SS8800B Power Crank Up Speaker Stand Level 2

By far the easiest method of raising speaker cabinets 80" off the floor. The easy-to-use power crank-up height adjustment system operates with either the removable manual handle or any standard electric or cordless drill. The upper shaft is constructed from extruded aluminum and the gear teeth are milled into the shaft, making it the most affordable solution on the market to cranking up speaker cabinets.
