The Multiquip 18121 is a genuine OEM Lever Plastic Knob 5/8" NC designed for Whiteman power buggy models including the WTB-16PD, WTB-16, WBH-16, WBH-21EFP, and WBH21EPA series. As a direct OEM replacement, this knob is produced to the same specifications as the original hardware installed at the factory, ensuring a proper fit on your machine's lever assembly. This part is the correct choice for operators running Multiquip's Whiteman track and hydraulic power buggies who need to restore full lever control functionality. Sourced directly through authorized channels, Multiquip 18121 is backed by the confidence of genuine OEM quality.
Key Features
- Genuine OEM Construction — Molded to the same material grade and thread specification as the original Multiquip production part, ensuring consistent grip and thread engagement on the lever assembly.
- 5/8" NC Thread Compatibility — Machined to a standard 5/8" NC thread pattern for clean, secure installation onto the lever shaft without rework or modification.
- Broad Power Buggy Fitment — Confirmed fit across WTB-16, WBH-16, WBH-21EFP, WBH-16EAWD, WBH-16EAWDF, WBH21EPA, and related Whiteman power buggy variants.
- Restores Positive Lever Control — A cracked, stripped, or missing knob makes lever adjustment difficult and imprecise; replacing it with 18121 restores the operator's ability to make confident, controlled adjustments.
- Operator Safety Compliance — Lever knobs are a direct operator contact point; using the correct OEM knob maintains the ergonomic and grip standards the machine was designed around, reducing the risk of unintended lever movement.
The lever plastic knob serves as the operator interface point on the buggy's control lever, giving the user a secure, comfortable grip when adjusting or locking lever positions during operation. Without a properly seated knob, the lever shaft is exposed, making precise adjustments difficult and increasing the chance of the lever slipping under load. Replacing a worn or damaged knob promptly keeps the operator in full control of the machine at all times.
