The Multiquip 21973 Guard Ring is a genuine OEM component designed for B46, B46S90, BS46H90, BS46H11, BH90C, BH11C, and BS90C series walk-behind power trowels. As a factory-sourced part, it meets the exact dimensional and material standards set by Multiquip, ensuring it seats and functions exactly as the original. Confirmed fitment spans both Whiteman and International walk-behind trowel configurations within these model families, so you can order with confidence knowing this is the correct part for your machine.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original material and dimensional tolerances, delivering the same service life expected from the factory-installed component.
- Direct Drop-In Fit — Engineered to seat correctly in the trowel's guard assembly without machining or modification, keeping your installation straightforward.
- Broad Trowel Compatibility — Fits B46, B46S90, BS46H90, BS46H11, BH90C, BH11C, and BS90C walk-behind power trowel models across Whiteman and International configurations.
- Structural Integrity Where It Counts — A properly fitted guard ring maintains correct blade guard alignment; a worn or missing ring can allow excessive movement that accelerates wear on surrounding components.
- Operator Protection — The guard ring is part of the blade guard system that shields operators and bystanders from rotating trowel blades — keeping this component in serviceable condition is essential for safe machine operation.
The guard ring is a structural retention component within the blade guard assembly of a walk-behind power trowel. It holds the guard in its correct position relative to the rotating finishing blades, preventing lateral displacement during operation. When this ring becomes worn, cracked, or deformed, the guard can shift out of alignment, exposing rotating parts and accelerating wear on adjacent hardware — making timely replacement critical for both machine longevity and operator safety.
