The Multiquip A400497402 Mast Locking Knob is a genuine OEM component designed for GBX12SK and GBX24BK balloon lighting systems. As a direct OEM replacement, this knob is built to the same specification as the original part, ensuring it installs and operates exactly as intended. Sourced directly through Multiquip's authorized parts network, the A400497402 is the correct part for maintaining the mast adjustment function on your balloon light unit. If your current knob is stripped, cracked, or missing, this is the verified replacement.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original design tolerances, ensuring the knob threads engage and lock with the same holding force as the factory-installed component.
- Direct-Fit Replacement — Matches the original mounting thread and knob profile on the mast assembly, allowing a straightforward swap without modification.
- Confirmed Fitment — Compatible with GBX12SK and GBX24BK balloon lighting systems; verify your model code before ordering.
- Mast Height Security — A functioning locking knob holds the mast at the correct extended height during operation; a worn or damaged knob can allow unintended mast movement and interrupt your lighting setup.
- Operational Safety — Secure mast locking is critical for stable overhead balloon light positioning — replacing a failed knob promptly prevents the mast from dropping unexpectedly during use.
The mast locking knob secures the telescoping mast of a balloon light system at the operator's chosen height, holding it firmly in position during use. Without a properly functioning knob, the mast cannot be reliably locked, which compromises both the stability of the light and the safety of anyone working beneath it. When the knob becomes stripped or damaged, the mast may slip or retract under the weight of the balloon light head, making immediate replacement essential for continued safe operation.
