The Genie 11209GT is a genuine OEM Flat Washer, USS 7/16 designed for a wide range of Genie telescopic and articulating boom lifts, as well as the Genie Load Lifter. As a factory-sourced component, this washer matches the original hardware specification used during assembly, so it seats and torques correctly without guesswork. Compatible models include S-series telescopic booms such as the S-60, S-65, S-80, S-85, S-100, S-105, S-120, S-125, S-100HD, S-120HD, S-60 HC, S-60 TRAX, S-65 TRAX, S-3200, and S-3800, as well as Z-series articulating booms including the Z-80/60, Z-135/70, and ZX-135/70. Cross-reference part number 11209GT against your parts manual to confirm fitment before ordering.
Key Features
- OEM-Grade Material and Sizing — Manufactured to the USS flat washer standard, this part delivers the correct load-bearing surface area and thickness for 7/16 fastener assemblies on Genie boom equipment.
- Direct Hardware Replacement — Installs in place of the original washer without modification, preserving correct clamp load and bolt engagement across fastened joints.
- Broad Boom Lift Compatibility — Fits an extensive range of Genie S-series telescopic and Z-series articulating boom lifts, plus the Genie Load Lifter, covering many of the most commonly used models in the field.
- Protects Fastened Surfaces — Distributes clamping force evenly across the mating surface, preventing fastener pull-through, surface damage, and joint loosening under vibration and load cycles typical of aerial lift operation.
- Supports Structural Integrity on Critical Assemblies — On boom lifts, fastener hardware is used throughout structural, hydraulic, and platform assemblies where correct torque retention directly affects safe machine operation.
A flat washer serves as a load-distributing interface between a fastener — typically a bolt or nut — and the surface it clamps. By spreading clamping force over a wider area, it prevents the fastener from pulling through or damaging softer or thinner materials, and it maintains consistent clamp load even under vibration and dynamic stress. On aerial boom lifts, flat washers appear throughout the machine in structural joints, hydraulic component mounting, and platform hardware, where maintaining proper fastener tension is essential to keeping assemblies secure during operation. When a washer deforms, corrodes, or goes missing, the fastener loses its bearing surface and clamping effectiveness, which can lead to loosened joints and accelerated wear on surrounding components.
