The km 24615 lighting speaker stand is a high quality stand for live pa systems or lighting. The auto lock system prevents the stand from suddenly lowering in height. The crank allows you to adjust the height easily and safely simply turn and the load will raise. No need to strain yourself when setting up for a gig. The additional locking screw further increases the safety and prevents any unwanted movement. The maximum load capacity is 35 kg so this stand is perfectly capable of handling many pa speakers and lights. The stand is also able to fold down for easy transport to and from venues. The integrated m10 threaded bush can be used to attach additional crossbars or other items. The height is adjustable up to 3 m making this ideal for many live situations. If you are looking for the best quality in your pa or lighting stands then km will certainly provide that with this product.
