M/K Drawing now offers an adjustable/removable brace for your trombone hand slide end bow. M/K Drawing purchased the same company who manufactured the Sauer Brace. This is an improved design, including more surface contact area for a sure grip on the slide ferrules and an elegant profile. We are bringing our brace to market to help players with slotting and response. This brace is available in three difference lengths, so we are sure to cover your model slide.
