The Genie 990340GT Flat Washer is a genuine OEM flat washer designed for Genie AL-series portable light towers, including the AL4, AL4L, AL5, AL5L, AL5HT, AL4000, and AL5000. Sourced directly from Genie, this flat washer meets the same specifications as the original hardware installed at the factory. It is the correct replacement for AL-series light towers requiring this size and finish of fastener hardware. Cross-reference part number 990340GT against your parts manual to confirm the exact application before ordering.
Key Features
- Genuine OEM Hardware Integrity — Manufactured to the same material grade and surface finish as the original, ensuring proper load distribution and corrosion resistance in outdoor light-tower applications.
- Drop-In Replacement — Matches the original bore diameter and outer dimensions exactly, so this washer installs directly without any rework to mating fasteners or mounting surfaces.
- Broad AL-Series Compatibility — Fits the Genie AL4, AL4L, AL5, AL5L, AL5HT, AL4000, and AL5000 portable light towers, covering the full range of current and recent AL-series models.
- Protects Fastened Joints — A correctly sized flat washer distributes clamping load evenly across the joined surface, preventing fastener pull-through and protecting the integrity of structural and panel connections on the light tower.
- Electrical and Enclosure Safety — Proper hardware fit on light-tower enclosures and electrical panel mounts helps maintain secure, vibration-resistant connections — important for equipment that runs unattended on live jobsites.
A flat washer serves as a load-spreading interface between a fastener head or nut and the surface being clamped. By distributing the clamping force over a wider area, it prevents the fastener from pulling through or damaging softer materials and keeps the joint secure under vibration. On portable light towers like the Genie AL series — which are regularly towed, repositioned, and exposed to generator vibration — hardware loosening is a real operational concern. When a washer is missing, undersized, or corroded, fastener joints can work loose over time, compromising panel integrity, structural connections, and the secure mounting of electrical components.
