The Genie 49409GT is a genuine OEM Lock Washer, M12 designed for a range of Genie equipment including GTH telehandlers, S series telescopic boom lifts, Z series articulating boom lifts, TMZ trailer-mounted booms, and TML light towers. As a direct OEM replacement, this lock washer is manufactured to Genie's original specifications, ensuring a correct fit without modification. Cross-reference part number 49409GT against your machine's parts manual to confirm this is the right washer for your application before ordering.
Key Features
- Direct OEM Replacement — Installs in place of the original lock washer with no rework, shimming, or adaptation needed.
- Broad Equipment Compatibility — Fits GTH series telehandlers, S-45 XC telescopic boom lifts, Z-34 IC and TMZ series articulating and trailer-mounted booms, and TML-4000N light towers.
- Fastener Integrity — A properly functioning lock washer resists loosening under vibration and load cycling; a worn or damaged one allows fastener back-out that can compromise the joint and lead to component movement or failure.
- Wide-Fleet Service Value — A single part number covers multiple machine families, making it a practical stock item for mixed Genie fleets.
A lock washer is placed beneath a nut or bolt head to prevent the fastener from loosening under vibration, dynamic load, or repeated movement cycles. The washer's spring tension or toothed profile bites into both the fastener and the mating surface, maintaining clamping force even as the machine operates over time. When a lock washer is deformed, cracked, or missing entirely, the fastener it supports can back out gradually, introducing unwanted play into the joint and potentially causing structural or mechanical failure at that connection point. Replacing a compromised lock washer promptly with the correct OEM part restores the designed clamping load and keeps the joint secure.
