The Kun Super fits 4/4 size and is one of our most popular shoulder rests. Height adjustable from 1 1/2 to 2 by lengthening/shortening screws, and legs pivot for pitch adjustment. The Kun Super differs from the Kun Original #1313 in that it has ten fine adjustment positions which are secured by a brass screw on the right end, and two stationary leg holes for adjustment on the left end. Some prefer this design as being more streamlined than the original model.
