SUPER-SCREW® Flexible Rubber Fastening System Fast, easy alternative to vulcanization The Super-Screw® Flexible Rubber Fastening System is a unique and innovative solution that acts as an alternative to vulcanization in even the toughest, most demanding applications. The flexible splice screws directly into the belt with great accuracy and precision, offering a solution that is truly like no other. In Any Space, in Any Weather Condition This revolutionary fastening system consists of a top and bottom piece of rubber, reinforced with one or more fabric plies for strength, along with pre-drilled holes that are fastened together with screws and a cordless drill and bit. This creates a strong, yet flexible splice that provides all the benefits of vulcanization without the challenges. With Super-Screw, you can install these flexible splices regardless of the location or accessibility of the conveyor belt and regardless of weather conditions. The Super-Screw Flexible Rubber Fastening System can be used on belts with skived belt thicknesses from 5/32” to 3/4”(4 mm to 19 mm), and pulley diameters as small as 6”. Sizes are available to accommodate PIW ratings up to 1200. Market Applications • Quarries • Cement plants • Crushed rock • Underground and surface mining • Coal • Hard-rock • Wood processing • Industrial minerals
