The Genie 1276779GT is a genuine OEM Stainless Steel Cotter Pin,.156X1.5, built for Genie GS scissor lifts including the GS-3384, GS-3390, GS-4390, and GS-5390. Sourced directly from Genie, this part meets the exact dimensional and material standards of the original component installed at the factory. Cross-reference part number 1276779GT against your machine's parts manual to confirm this is the correct pin for your unit before ordering.
Key Features
- Stainless Steel Construction — The SS designation confirms a stainless steel alloy, offering solid corrosion resistance in the demanding, outdoor environments where large-platform scissor lifts operate.
- Exact Dimensional Match — At .156X1.5, this cotter pin conforms to the precise diameter and length called out in the Genie parts manual, ensuring correct installation without reworking the fastener hole or clevis.
- Genuine OEM Part — Manufactured to Genie's own specification, this component delivers the material grade and dimensional conformity needed for a proper OEM-quality repair.
- Confirmed GS Series Fitment — Designed for the GS-3384, GS-3390, GS-4390, and GS-5390 — Genie's larger-platform, rough-capable scissor lift models.
- Retention Integrity — A cotter pin that is bent, corroded, or missing allows the pin or bolt it secures to back out during operation. Replacing a worn one promptly keeps fastened joints locked in position on the machine.
- Safety-Critical Fastener — Cotter pins are used on pivot points and load-bearing joints throughout aerial lifts. Using the correct OEM-spec part on these locations is an important part of maintaining the machine's structural integrity.
A cotter pin is a small split-pin fastener inserted through a drilled hole in a bolt, shaft, or clevis pin to lock it in place and prevent it from backing out under vibration or load. Once installed, the pin's legs are bent outward to secure it permanently until the joint is deliberately serviced. When a cotter pin fails, breaks, or goes missing, the fastener it retains can walk free — allowing movement in joints that must remain fixed. On scissor lifts, where pivot points and structural connections are subject to repeated cycling and load, keeping every cotter pin in serviceable condition is a routine but important part of preventive maintenance.
