The Genie 57587GT is a genuine OEM Plug, 4", Capplug designed for Genie and Terex portable light towers, including the AL4000, AL5000, AL5HT, AL4, AL5, AL5 with Vertical Mast, and TML-4000N. As a factory-sourced replacement, this plug matches the original specification exactly, so it seats and seals the same way the production part did. Cross-reference part number 57587GT against your machine's parts manual to confirm this is the correct item for your unit before ordering.
Key Features
- Genuine OEM Fit — Sourced directly from Genie, this plug meets the original dimensional and material specification for a correct, secure seat every time.
- Correct 4" Size — The 4" cap dimension is the identifying spec for this plug; it installs into the designated port or opening without modification.
- Broad Light Tower Coverage — Fits a wide range of Genie and Terex portable light tower models, including the AL4000, AL5000, AL5HT, AL4, AL5, and TML-4000N.
- Port Protection — A properly seated plug keeps contaminants, debris, and moisture out of the opening it covers, protecting the surrounding components during storage, transport, or service intervals.
A capplug is a close-fitting cap or plug used to seal an opening, port, or tube end on a piece of equipment. It protects the opening from dirt, dust, and moisture that could otherwise reach internal components during storage or while work is being performed nearby. When a capplug is missing, cracked, or ill-fitting, the port it covers is left exposed — increasing the risk of contamination that can cause premature wear or damage to adjacent parts. Replacing a damaged or missing plug promptly with the correct OEM part keeps the opening properly protected.
