The SBR is different from standard batten receptacles in that it fits inside the batten pocket, making it invisible on the outside except for the small fastening plate. Thereby almost completely eliminating chafe on the mast and rigging. Moreover the batten will be not on one side, but perfectly in the middle. Each SBR includes: the main body; side plates to fix the receptacle to the sail; trimming screw for batten compression; the cap with a threaded hole to screw the receptacle in the toggle of the batten slider.
