Belting Accessories

Both are ways to join belt ends without vulcanizing, but they work differently. Mechanical fasteners like the Clipper® Wire Hook System use individual metal hooks pressed into the belt in a staggered-grip pattern, giving a low-profile, quiet-running splice that doesn't compromise the belt carcass. Lacing systems like the Alligator® Lacing System use a one-piece hammer-applied splice plate that spans the belt width, requiring no special tools and providing uniform tension across the joint. In general, lacing systems are faster and simpler to install in the field, while mechanical fasteners like Clipper offer a lower profile that runs more quietly over pulleys.

Dura-Splice and Maxi-Splice are belt clamp fasteners purpose-built for elevator belts, not general conveyor splicing. They use a vice-like grip between three heavy-duty grooved plates and fit all pulley diameters with one size, which eliminates the double belt-thickness and wasted material that comes with traditional lap or butt rider splices. They're rated for belts up to 800 PIW and 1/2" overall thickness, and because the belt isn't weakened with excess bolt holes, they offer more load capacity and safety margin than standard bolted splices. If you're splicing an elevator belt rather than a general conveyor belt, Dura-Splice/Maxi-Splice is the purpose-built choice.

Alligator® Lacing is a one-piece splice plate that's hammer-applied directly to the belt end — no press, no special installation tools, and no pre-drilling required the way some mechanical fastener systems need. Its one-piece design spreads tension evenly across the full belt width and is engineered so individual pieces can't work loose over time. It's a good fit for field repairs or installations where portability and installation speed matter more than the lowest possible splice profile.

Adhesives like Polycol A&B are used for Thermofix joining of belts with a PET-fabric traction layer, bonding the belt carcass and its rubber coatings without any mechanical hardware. This approach is typically used when a smooth, gapless splice is required — mechanical fasteners and lacing systems both leave a raised or jointed profile at the splice, while a properly cemented joint runs flush with the rest of the belt. Adhesive splicing generally requires more controlled installation conditions and cure time than a hammer-applied or press-fit mechanical splice, so it's best suited to shop installations or applications where splice profile and smoothness matter more than installation speed.

Dura-Splice and Maxi-Splice fasteners are available in Standard (zinc-plated cast ductile iron) or Non-Sparking (cast bronze) versions. Standard fasteners are the right choice for typical industrial environments. Non-Sparking bronze fasteners are necessary anywhere combustible dust, flammable vapors, or other spark-sensitive conditions are present — the same category of environments that call for FR/SC belting — since a ferrous metal fastener striking a pulley or guard could otherwise generate a spark. If your facility has any explosion-risk classification, confirm you're specifying the non-sparking option.
