Key Features
- Genuine OEM Construction — Zinc-plated steel with the snub profile and 1/2X2-3/4 dimensions specified by Genie engineering — no guesswork on material grade or bearing surface.
- Direct Drop-In Replacement — Matches the original fastener stack in bolt pattern and thickness so this washer seats correctly without rework or shimming.
- Broad Light Tower Coverage — Fits Genie AL and RL series light towers and Terex TML series mobile light towers, including AL4, AL4L, AL4000, AL5, AL5L, AL5HT, AL5000, RL4, RL4000, TML-4000, and TML-4000N.
- Load Distribution You Can Count On — A correctly sized snub washer spreads clamp load evenly across the mating surface, preventing fastener pull-through and protecting structural connections on the mast or frame.
- Zinc Plating for Corrosion Resistance — The ZN finish guards against rust in outdoor and variable-weather jobsite environments where light towers typically operate.
A flat washer serves as a load-spreading interface between a fastener — bolt head or nut — and the surface it bears against. Without the correct washer, clamping force concentrates in a small area, which can damage the mating surface, allow fasteners to loosen under vibration, or cause premature joint failure. The snub profile of this washer provides a wider bearing surface relative to its hole size, making it especially effective in applications where pull-through resistance matters. On light tower assemblies, where mast hardware and structural fasteners are subjected to road vibration during towing and repeated setup cycles, using the correct OEM-spec washer helps keep connections secure and the unit operating as designed.
