Key Features
- Genuine OEM Quality — Manufactured to Genie's original material and dimensional specifications, this nylon plug delivers the same grade and fit as the part it replaces.
- Exact Dimensional Match — The 1.38-inch domed profile seats correctly in the designated opening, providing a flush, secure fit without reworking the surrounding structure.
- Broad Boom Lift Coverage — Compatible with Genie S-80X, S-80, S-85, and Z-60/34 boom lifts, covering both telescopic and articulating boom families.
- Durable Nylon Construction — The black nylon material resists impact and environmental exposure, maintaining its shape and secure seating across demanding jobsite conditions.
- Protective Function — A correctly installed plug keeps openings sealed against debris, moisture, and contaminants, preventing damage to the surrounding structure over time.
A domed nylon plug is used to close and protect an opening in the machine's structure or enclosure — blocking out dirt, moisture, and debris that could otherwise reach internal components. When a plug is cracked, missing, or the wrong size, the opening it covers is left exposed, allowing contaminants to accumulate in areas where they can cause corrosion or interfere with adjacent components. Replacing a worn or damaged plug with the correct OEM part restores the intended protection and keeps the opening properly sealed.
