Alligator® Spiral Lace
The Alligator® Spiral Lace Fastening System is ideal for belt operations with small head pulleys that require both non-metallic and low-profile fasteners.
The Alligator® Spiral Lace Fastener system was designed for small pulley, low-profile applications. The fastener is constructed of polyester webbing, spirals, and hinge pins. It is installed by either insertion between the plies, ply stepping, or finger splicing.
Maximum operating temperature is 320°F.
