Key Features
- Genuine OEM Construction — Manufactured to Genie's original dimensional and material specifications, ensuring the pin meets the same standards as the part it replaces.
- Exact Dimensional Fit — Sized at .25 x 1.5 to match the original fastener position precisely, seating and locking as intended without modification.
- Broad Genie Fitment — Compatible with the Genie GRC-12 vertical mast lift and the Z-30/20HD articulating boom lift; always confirm against your serial-specific parts manual.
- Secure Retention — A correctly installed cotter pin locks pins, bolts, and clevis assemblies in place, preventing unintended movement or loosening during operation.
- Safety-Critical Fastener — Cotter pins are locking components on aerial work platforms; using the correct OEM size ensures the locking function performs as designed, which matters on any machine carrying personnel.
A cotter pin is a small split-pin fastener inserted through a hole in a bolt, shaft, or clevis pin and then bent open to lock the assembly together. It prevents rotation or axial movement of the fastened component, keeping pivot points, linkages, and structural connections secured during machine operation. When a cotter pin is missing, worn, or the wrong size, the fastener it secures can back out or shift, which can affect the function of the connected assembly and should be corrected with the proper OEM replacement promptly.
