Multiquip 507416 Stationary Grate

The Multiquip 507416 Stationary Grate is a genuine OEM replacement designed for the EM90 and WM90 series plaster and mortar mixers, including the EM90SH8, EM90PH8, EM90PE, EM90SE, WM90SH8, WM90SE, WM90PH8, WM90PE, WM90PLF, WM90SLF, and WM90S/P models. Sourced directly from Multiquip, part 507416 is built to the same specifications as the original component installed at the factory. This stationary grate drops in as a direct replacement with no guesswork — the correct part for these Essick and Whiteman mixer platforms. If your mixer's grate is cracked, deformed, or missing, replacing it promptly with the correct OEM part keeps the drum operating as intended.

Key Features

• Genuine OEM Construction — Manufactured to Multiquip's original material and dimensional specifications, ensuring the grate holds up to the abrasive demands of plaster and mortar mixing cycles.
• Direct-Fit Replacement — Engineered to seat correctly in the drum opening of EM90 and WM90 series mixers without cutting, trimming, or adapting.
• Broad EM90 and WM90 Compatibility — Confirmed fitment across Essick and Whiteman 90-class mixer variants, including Honda, electric, and MPower-powered configurations.
• Protects Mix Quality — A properly seated stationary grate controls material flow and prevents oversized aggregate or debris from passing through, keeping batch consistency where it needs to be.
• Verified Part Number — Ordering by Multiquip part number 507416 eliminates compatibility risk — the right part the first time, backed by OEM traceability.

The stationary grate sits at the discharge opening of the mixer drum and acts as a screen or barrier that controls what passes through as mixed material exits the drum. It keeps oversized chunks, unmixed clumps, or foreign debris from entering the output stream, which is especially critical when working with plaster or mortar where batch consistency directly affects finish quality. When the grate becomes cracked, warped, or broken, material flow becomes uncontrolled and mix quality suffers — replacing it with a correctly sized OEM grate restores the drum to proper working order.
