The ProX X-SW15 is an adjustable stand that sits on three locking casters for easy positioning. The stand is for PA and lighting setups and features 1-3/8" thread on the top pole for mounting speakers and lights. The height-adjustment range of the stand is 35 to 59". Constructed out of aluminum and iron—with all the durability those two elements provide—the stand can collapse quickly thus facilitating ease in transportation.
