The new RPS Studio Double Crossbar Holders (one pair) allow two additional crossbars to be attached to the RS-1990 or RS-2000 background supports, one in the front and one in the back of the usual position of the crossbar. The holders can rest above or below the original crossbar of the background support via a 1/2” pass through. They are made of approximately 1/8th inch thick metal that is 2-1/8” wide and have two 3/8” threaded 1-3/4” long posts to drop one or two RS-2003 Adjustable Cross Bars (optional) onto and wing nuts to secure the crossbar(s) in place.
