Multiquip 20437 QP Latch Pin

The Multiquip 20437 QP Latch Pin is a genuine OEM replacement designed for a wide range of Whiteman and International walk-behind power trowels, including BS46H11, BS46H90, JS36H55, JS36H90, B46, B46S90, BH11C, BH90C, BS90C, HDA-SERIES, J3036H55, J36-M30, JH55C, JH90C, and JS60C models. As a direct OEM component sourced through Multiquip's authorized parts network, the 20437 is built to the same specification as the original hardware installed at the factory. Keeping this small but critical latch component in good condition ensures the trowel's guard and handle mechanisms operate safely and correctly on every pour.

Key Features

• Genuine OEM Hardware Integrity — Manufactured to exact Multiquip OEM specification, ensuring correct pin diameter, material grade, and shear strength for this latch application.
• Direct-Fit Installation — Drops into the existing latch assembly without modification, aligning precisely with the quick-pitch or guard mechanism it secures.
• Broad Trowel Compatibility — Confirmed fitment across BS46, JS36, B46, BH, BS90C, HDA-SERIES, J3036H55, J36-M30, JH, and JS60C series walk-behind and ride-on power trowels.
• Secure Latch Engagement — A correctly fitted latch pin keeps the guard or pitch-adjustment mechanism locked in position, preventing unwanted movement during finishing operations.
• Operator Safety Relevance — Latch pins are load-bearing retention components; a worn or missing pin can allow guard or handle assemblies to shift unexpectedly, creating a hazard during operation.

The QP latch pin is a retention fastener within the quick-pitch or guard latch assembly on Multiquip and Whiteman power trowels. Its role is to lock the latch mechanism in place, holding the guard or handle component securely during operation. When the pin wears, deforms, or goes missing, the latch can slip or disengage, compromising both the accuracy of blade-pitch adjustment and safe operation of the machine. Replacing a worn latch pin promptly restores the integrity of the assembly and keeps the trowel performing as intended.
