The EB-TY provides a unique method of fastening deck boards that makes the fasteners virtually invisible. Fastening is done into the side of the board, leaving a fastener-free deck surface. The EB-TY is a polypropylene biscuit fastener that fits into a slot the builder cuts into the edge of the deck boards with a standard biscuit joiner. The EB-TY fasteners are inserted and fastened with a screw driven into the joist. Nesting each successive board against the EB-TY automatically ensures consistent spacing and uniform height.
