The RBS-TDISP incorporates the features of the CRB Multi-Roll Tape Dispenser onto a rolling base that travels along your RBS Aluminum Track. Perfect for keeping your tape right where you need it during decorative work such as butt wraps or inlays. It can hold up to three different rolls of different width tape at one time. (Photo shows 1/2", 1/4" and 1/8" tape). Holds rolls with a max diameter of 5.5” and core size of 3”. Tape sold separately. Great for hobby projects too!
