Key Features
- Genuine OEM Construction — Manufactured to Genie's original specifications, with correct thread form and material grade for a 1" NPT electrical fitting application.
- Exact Thread Compatibility — The 1" NPT thread spec matches the original fitting, allowing direct installation without reworking the mating connection.
- Broad Genie Fitment — Fits a wide range of Genie S, SX, Z, ZX series boom lifts and select GS series scissor lifts, making it a versatile stock item for fleets running multiple Genie models.
- Secure Electrical Enclosure Integrity — A properly torqued locknut keeps the electrical fitting firmly seated, preventing movement and maintaining the integrity of the connection point it secures.
- Direct OEM Source — Sourced as a genuine Genie part through DHS Equipment, backed by OEM provenance for parts traceability and confidence in fitment accuracy.
An electric locknut is a threaded fastener used to secure conduit fittings or electrical connectors at a panel, enclosure, or junction box entry point. It threads onto the fitting from the inside of the enclosure and is tightened against the surface to lock the fitting in place and prevent rotation or loosening from vibration. On aerial lift equipment, where machines operate across uneven terrain and experience continuous movement, a loose or missing locknut can allow a fitting to shift, compromising the connection it holds. Replacing a worn or damaged locknut with the correct OEM part restores a firm, stable mounting point for the electrical fitting it serves.
