The Genie 122079GT is a genuine OEM Hardened Flat Washer, 1.000 designed for a wide range of Genie aerial lifts and light towers. As a direct OEM replacement, this washer is manufactured to the same material and hardness standards as the original hardware installed at the factory, ensuring correct load distribution and fastener integrity across every application it serves. This part fits telescopic boom lifts including the S-40, S-45, S-60, S-60 XC, S-60 HC, S-60 TRAX, S-60X, S-65, S-65 TRAX, S-80, S-80X, S-85, S-100, S-100HD, S-105, S-120, S-120HD, S-125, and S-3200 and S-3800 models, articulating booms including the Z-40/23N, Z-40/23N RJ, Z-45/22, Z-45/25J IC Power, Z-60/34, Z-135/70, and ZX-135/70, the GTH-844 telehandler, and light towers including the AL4, AL4L, AL4000, AL5, AL5L, AL5000, AL5 with Vertical Mast, RL4, RL4 LED Vertical Mast, RL4 Vertical Mast, RL4000, TML-4000. Cross-reference part number 122079GT against your Genie parts manual to confirm the correct application before ordering.
Key Features
- Genuine OEM Hardness Rating — Manufactured to the original hardened specification, this washer resists deformation under the high clamp loads common in aerial-lift and telehandler fastener assemblies.
- Correct 1.000 Bore Sizing — The 1.000 inner diameter seats flush against the correct fastener shank, distributing clamping force evenly without movement or rocking at the joint.
- Broad Cross-Family Fitment — A single part number covers Genie S and Z series boom lifts, GTH telehandlers, and AL, RL, and TML light towers, making it a practical stocking item for mixed fleets.
- Structural Joint Integrity — A hardened washer prevents fastener heads and nuts from pulling into softer base material over time, maintaining the clamping force that structural and pivot connections depend on.
- Safety-Critical Fastener Support — On aerial-lift platforms and boom structures, fastener joint integrity is directly tied to safe operation; using the correct hardened washer helps preserve the designed clamping performance of those connections.
A hardened flat washer serves as the load-spreading interface between a fastener — a bolt head or nut — and the surface it bears against. By distributing the clamping force over a wider area, it prevents the fastener from sinking into or damaging the mating material, which is especially important on structural connections, pivot points, and mounting surfaces on aerial lifts and telehandlers. When the wrong washer is used — one that is too soft, too thin, or incorrectly sized — the joint can lose clamp load over time as the washer deforms, leading to loosened fasteners, accelerated wear on adjacent components, and potential structural movement in assemblies where tight tolerances matter.
