The Sennheiser EW-D SK Belt Clip Vertical (article 508993) is a replacement and alternative spring-steel belt clip for the EW-D SK digital bodypack transmitter from Sennheiser's Evolution Wireless Digital series. As its name indicates, it is designed for wearing the bodypack in a vertical orientation, which can suit presenters, actors, fitness instructors or musicians who need the pack to sit differently on a belt, waistband or guitar strap, or who need a spare after a clip has been bent or lost. The clip is a formed wire design that attaches to the back of the SK in place of the standard clip; it adds very little bulk and weighs only about 12 g. It is a genuine Sennheiser spare part, supplied as a single clip without the transmitter, and Sennheiser lists a 2-year warranty. It is listed by Sennheiser specifically as an EW-D SK accessory. Useful to keep in the spares kit of rental companies, schools, churches and venues running EW-D systems.
