All of our materials are cut using state-of-the-art Gerber computerized cutting equipment. The individual parts are designed using the latest CAD equipment and inspected by our expert design staff before the actual top is cut for production. All of the finishing bindings used in production match the texture and color of the topping. The main seams are all double-stitched for strength and durability. Vinyl and cloth tops are heat-sealed on the outside and cloth tops receive an additional heat-seal with hot-tape on the inside of the top. Both of theses processes ensure a waterproof seal. Our tops are all sewn with premium polyester threads which are UV protected to ensure the longevity of the top. This top includes rubber secondary weather seals to further ensure a weatherproof, tight seal against the door windows and the top.
