How Alligator® Fasteners Work Alligator® developed to bring the many advantages of mechanical belt fasteners to those applications where metal belt fasteners could not be used. They are external, cover-mounted fasteners employing a one-piece, integrated design with rivets molded into the top plates of the fasteners. Lace Fastener System. The Alligator® Plastic Rivet Fasteners were Applications • Baggage Handling • Food Processing • X-Ray Equipment • Pharmaceutical • Indexing Conveyors • Mail Sortation Alligator® Rivet Installation Method Plastic Alligator® Spiral Lace Pass through pre-punched holes and are Spin-Set TM compressing the fastener plates and fi nishing the splice. , How to Specify the Correct Alligator® Metallic Fastener Non- 1. Determine Belt Tension (PIW). 2. Measure your Belt Thickness. 3. Measure the Diameter of the Smallest Pulley in your Drive with Belt Wrap more than 90°. 4.
