The Genie 139451GT is a genuine OEM Painted Sliding Midrail Tube designed for a wide range of Genie telescopic and articulating boom lifts. Sourced directly from Genie, this component meets the exact material and finish specifications of the original part, ensuring a proper fit on models including the S-80, S-80X, S-85, SX-150, SX-180, S-120, S-125, Z-60/34, and Z-30/20HD, among others across the S, SX, and Z boom families. As a genuine OEM component, it carries the same part number cross-reference — 139451GT — used in Genie's official parts documentation, so you can confirm compatibility with confidence before ordering. When a midrail tube is cracked, missing, or damaged, replacing it promptly with the correct part is critical to restoring a compliant and safe platform guardrail system.
Key Features
- Genuine OEM Construction — Manufactured to Genie's original material grade and painted finish specification, matching the structural integrity of the factory-installed component.
- Direct Slide-In Replacement — Engineered to fit directly into the existing midrail channel on compatible boom platforms, replicating the original mounting geometry without rework.
- Broad Boom Family Coverage — Fits Genie S and SX telescopic booms and Z articulating booms, including the S-80, S-85, SX-150, SX-180, S-40, S-45, S-60, S-65, S-100, S-105, S-120, S-125, Z-60/34, and Z-30/20HD.
- Painted Finish for Durability — The factory-applied painted finish provides a corrosion-resistant surface suited for the outdoor and variable weather conditions typical on boom lift jobsites.
- Platform Guardrail Integrity — A functioning midrail is a required element of the platform guardrail system on aerial lifts. Replacing a damaged tube restores the guardrail to its designed configuration, supporting operator safety at height.
The sliding midrail tube is a structural component of the work platform guardrail assembly on boom lifts. It sits between the toeboard and the top rail, sliding within the midrail channel to allow the platform gate or guardrail section to open and close as needed for safe entry and exit. When this tube is bent, cracked, or missing, the guardrail system is compromised — leaving the platform out of compliance with fall-protection requirements and potentially unsafe for personnel working at elevation. Replacing a worn or damaged tube with the correct OEM part restores the full guardrail assembly to its intended configuration and keeps the machine ready for safe operation.
