Key Features
- Genuine OEM Hardware Grade — Zinc-plated (ZP) finish provides corrosion resistance suited to outdoor light-tower environments, matching the original hardware specification from Genie.
- Direct Assembly Fit — The 3/4 sizing aligns with the fastener hardware used throughout AL and RL series light towers, seating flush without shimming or adjustment.
- Broad Light-Tower Coverage — Fits a wide range of Genie and Terex portable light towers including the AL4000, AL5000, RL4000, TML-4000, AL4L, AL5L, and AL5HT series.
- Load Distribution Where It Counts — A properly rated flat washer spreads clamping force evenly across fastened joints, protecting mast and frame components from surface damage under tension.
- Stock Multiple for Scheduled Service — Flat washers are consumed during routine maintenance and field repairs; keeping extras on hand means service calls are completed in a single trip.
A flat washer serves a straightforward but important role in any bolted assembly: it distributes the clamping load of a fastener across a wider surface area, preventing the bolt head or nut from pulling into or damaging the material underneath. On light towers like the AL and RL series, flat washers appear throughout mast joints, panel mounts, and generator and engine hardware where consistent clamping force is essential to structural integrity. When a washer is missing, undersized, or corroded through, the fastener joint can loosen prematurely or cause surface damage to surrounding components — making timely replacement with the correct OEM part an important part of keeping a light tower in solid working condition.
