The Genie 1261799GT is a genuine OEM Lock Washer, 1/2 ZP designed for the RL4 Vertical Mast. Sourced directly from Genie, this lock washer is an exact match to the original hardware used during assembly, ensuring correct clamping force and thread security right out of the box. Cross-reference part number 1261799GT against your RL4 parts manual to confirm fitment before ordering.
Key Features
- Genuine OEM Hardware Grade — Zinc-plated 1/2" construction meets the original material and finish specification, delivering the corrosion resistance and hardness the application demands.
- Direct Bolt-On Replacement — This lock washer seats onto the fastener stack exactly as the original, requiring no sizing adjustments or secondary hardware.
- Verified Fitment for the RL4 Vertical Mast — Engineered and validated specifically for the RL4, so there is no guesswork about whether this washer belongs in your machine.
- Maintains Clamp Load Integrity — A functioning lock washer prevents fastener loosening under vibration and dynamic load cycles; a worn or missing one allows bolt back-out that can compromise structural connections over time.
- Operational Safety Relevance — On a vertical mast unit, secure fastening at critical joints is essential to safe lifting operation. Replacing worn hardware with a correct OEM washer helps maintain the mechanical integrity of those connections.
A lock washer is a thin, hardened ring placed under a nut or bolt head to resist loosening caused by vibration, torque, and cyclical loading. Its split or toothed profile bites into both the fastener face and the mating surface, creating mechanical resistance that keeps the joint tight over the life of the assembly. When a lock washer becomes flattened, corroded, or missing entirely, the fastener it secures can work loose — leading to joint movement, accelerated wear on surrounding components, and potential structural failure at the connection point.
