Neotech's BRASS SLING now offers a new longer NEO LOOP connector at the bottom to fit the larger tubes on certain instruments. The NEO-LOOP connectors fasten to the instrument's strap rings, or around the instrument's tubing. Simply snap the quick disconnects to the strap and you're ready to go! The non-skid surface on the back of the pad assures that it remains securely on your shoulder. - the manufacturer
