Key Features
- Genuine OEM Construction — Manufactured to the original design specification for the 20389 Q.P. Handle, delivering the same structural integrity and ergonomic function as the factory-installed component.
- Direct Bolt-On Replacement — Engineered to align with the existing mounting points on compatible Whiteman and International walk-behind trowel frames, keeping installation straightforward.
- Broad Trowel Compatibility — Fits a wide range of walk-behind power trowel series including HDA, B46, J36-M30, BS90C, BH90C, BH11C, JS60C, JH90C, JH55C, BS46H11, BS46H90, JS36H90, and JS36H55.
- Operator Control Integrity — A correctly functioning Q.P. (Quick Pitch) handle gives the operator precise blade pitch adjustment at the grip; a worn or damaged handle compromises blade control and finishing consistency.
- Authorized Multiquip Part — Sourced through official Multiquip distribution, part number 20389 carries the assurance of authentic OEM lineage — not a substituted aftermarket approximation.
The Q.P. (Quick Pitch) handle is the primary operator interface on a walk-behind power trowel, allowing the user to adjust the pitch angle of the trowel blades while the machine is in motion. By changing blade pitch, the operator controls the finishing pressure applied to the concrete surface, which directly affects surface flatness and finish quality. When the handle mechanism wears, loosens, or fails, blade pitch becomes inconsistent or unresponsive — leading to uneven finishing results and potential operator fatigue from compensating at the grip.
