The Genie 990410GT is a genuine OEM Flat Fender Washer, 1/2 designed for Genie AL-series portable light towers, including the AL4, AL4L, AL5, AL5L, AL5HT, AL5 with Vertical Mast, and AL5000. As a genuine OEM part, this washer is manufactured to the same specification as the original hardware installed at the factory, ensuring correct fit and function without any guesswork. Cross-reference part number 990410GT against your parts manual before ordering to confirm this is the right component for your unit.
Key Features
- Genuine OEM Hardware Integrity — Manufactured to the original specification for the AL-series light tower platform, delivering the correct bearing surface, diameter, and material grade every time.
- Wide-Surface Load Distribution — The fender washer's oversized flange spreads clamping load across a broader area than a standard washer, protecting the mounting surface from pull-through and deformation.
- Direct Drop-In Replacement — Matches the original 1/2 inch fastener interface exactly, seating flush with no reworking of the surrounding hardware or structure.
- Broad AL-Series Compatibility — Fits the AL4, AL4L, AL5, AL5L, AL5HT, AL5 with Vertical Mast, and AL5000, covering the core Genie portable light tower lineup in a single part number.
- Structural Reliability at Connection Points — A worn, undersized, or missing washer at a critical joint can lead to loosened fasteners and compromised structural connections on the light tower mast or generator frame; replacing it promptly keeps those joints secure.
A flat fender washer serves as a load-spreading interface between a bolt head or nut and the material being fastened. Its wider outer diameter distributes clamping force over a larger surface area, which prevents the fastener from pulling through softer or thinner materials and reduces the risk of surface damage at the joint. When a washer is missing, deformed, or corroded, the fastener can work loose under vibration and load cycles — a common condition on towable light towers that are regularly transported between jobsites — leading to joint movement, accelerated wear on surrounding components, and the potential for structural fasteners to back out entirely.
