Key Features
- Genuine OEM Construction — Manufactured to Genie's original material and dimensional standards, so this pin fits and functions exactly as the factory-installed part.
- Direct Drop-In Replacement — Engineered to the same profile as the original, this pin installs without rework or adaptation.
- Broad Light Tower Compatibility — Fits Genie AL4000, AL5000, RL4000, and TML-4000 portable light towers, covering a wide range of jobsite lighting equipment.
- Retention You Can Count On — A sound lynch pin keeps connected components securely locked in position; a worn or missing one allows unintended movement and should be replaced promptly.
- Operational Safety — Lynch pins are a primary retention fastener on light tower assemblies. Using the correct OEM part maintains the mechanical integrity of the connection it secures.
A lynch pin is a quick-release fastener used to lock a clevis pin, axle, or shaft in place, preventing it from walking out of its bore during operation or transport. On portable light towers such as the AL4000 and TML-4000, lynch pins are commonly used at articulation points, tow connections, and outrigger assemblies to keep components seated and secure. When a lynch pin is lost, bent, or deformed, the pin it retains can work loose, compromising the stability of the assembly it holds. Replacing it promptly with the correct OEM part restores full retention and keeps the connection operating as intended.
