Multiquip 20797 Stationary Guard Ring

The Multiquip 20797 is a genuine OEM Stationary Guard Ring designed for Heavy Duty Series, BA-Series, HPHA, and HPLA walk-behind power trowels. As a direct Multiquip OEM part, it is manufactured to the same specifications as the original component installed at the factory, ensuring an accurate fit across compatible models. This ring is confirmed for use on Heavy Duty Series, HPHA36C5H, HPHA46411H, HPLA46411H, and related BA-Series and HPLA-HPHA-36 units. Keeping this component in good condition is essential to safe and efficient trowel operation on any concrete finishing job.

Key Features

• OEM-Grade Ring Material — Produced to Multiquip's original dimensional and material specifications, ensuring the guard ring seats and retains position correctly within the trowel assembly.
• Direct-Fit Replacement — Designed to install in the same position as the original, with no rework or adjustment needed to mounting points on compatible walk-behind trowel models.
• Broad Walk-Behind Trowel Compatibility — Fits Heavy Duty Series, BA-Series, HPHA36C5H, HPHA46411H, HPLA46411H, HPHA-46-Series, and HPLA-HPHA-36 machines.
• Blade Guard Integrity — A properly functioning stationary guard ring keeps the rotating blade assembly correctly contained, supporting consistent blade pitch and protecting the operator from contact with moving components.
• Safety-Critical Component — The guard ring is part of the blade guard system on walk-behind trowels; using the correct OEM replacement maintains the machine's intended operator protection configuration.

The stationary guard ring on a walk-behind power trowel acts as the fixed outer boundary of the blade guard assembly, holding the rotating blades within their designed operating envelope during concrete finishing passes. It works in conjunction with the trowel's blade pitch mechanism to keep geometry consistent and prevent the blades from shifting outside their intended arc. When this ring becomes cracked, warped, or worn, blade containment is compromised — which can affect finish quality and, more critically, operator safety around the spinning blade assembly.
