Alligator Lacing - a tooth-type, hammer-in mechanical conveyor belt fastener offered by Flexco - forms a continuous hinged splice quickly installed on-site with simple hand tools.

Designed for flat power-transmission or conveyor belts, it is available in a wide range of sizes to fit belts from less than 1/16in (1.6mm) to 1/2in (13mm) thick.

Alligator Lacing is produced in single-piece strips and a variety of lengths for all standard belt widths.

Strip construction assures a straight, uniform splice across the belt.

For easy stocking and convenient field use, splice materials are packaged in kits that include patented, time-saving installation clips.

These devices hold the strips firmly and squarely on the belt end, allowing one person to install the splice easily with an ordinary hammer.

Fastener teeth are joined by a common bar that prevents individual teeth from working out of the belt and ending up in the conveyed material, especially important in food processing and stock feeding applications.

The teeth are designed to avoid severing longitudinal (lengthwise) belt carcass fibers vital to belt strength.

The fasteners also provide a flat, low-profile splice that operates smoothly around pulleys and under diverters, cleaners or shears.

Conveyor-type Alligator Lacing strips are produced with a radius check, or shallow rounded notch, between tooth segments, which helps resist inadvertent separation of strip segments when running over crowned pulleys often used to control conveyor tracking.

For power transmission applications where narrow-width belts and high-speed operation are common, Alligator Power-Transmission Lacing strips include special rocker-type hinge pins comprising two oval-shaped halves that rock against each other as the splice flexes around pulleys.

This design greatly reduces friction wear and extends splice life.

Both power-transmission and conveyor lacings are available in steel, Type 316 Stainless Steel, or Monel -- a copper/nickel alloy featuring high resistance to abrasion, rust and corrosive acids.
