The Multiquip 507417 Moveable Grate is a genuine OEM replacement component designed for Essick and Whiteman plaster and mortar mixers, including the EM-90S, EM-90P, EM-900S, EM-900P, WM-900S, WM-900P, and related EM90 and WM90 series models. As a direct OEM part, the part is manufactured to the same specifications as the original, ensuring consistent fit and function across the supported mixer lineup. Whether you are servicing an Essick or Whiteman unit, this grate is the correct factory replacement to restore your mixer to full working condition. Verify your model code against the fitment list before ordering to confirm compatibility.
Key Features
- Genuine OEM Construction — Manufactured to original Multiquip specifications, so the grate dimensions, bar spacing, and material grade match what came on your mixer from the factory.
- Drop-In Fitment — Designed to seat directly into the mixer drum opening without cutting, grinding, or modification, using the same mounting points as the original grate.
- Broad Mixer Compatibility — Fits a wide range of Essick and Whiteman 90-series plaster and mortar mixers, including EM-90S, EM-90P, EM-900S, EM-900P, WM-900S, WM-900P, EM90SH8, EM90PH8, WM90SH8, WM90PLF, WM90SLF, and additional EM90 and WM90 variants.
- Controls Material Flow — The moveable grate regulates how mixed material exits the drum, giving operators consistent control over discharge rate and mix quality on every batch.
- Durable for Abrasive Materials — Built to withstand repeated contact with mortar, plaster, and stucco mixes, which are highly abrasive and accelerate wear on undersized or inferior grate components.
The moveable grate on a plaster and mortar mixer controls the discharge of mixed material as the drum rotates and tips. By opening and closing the grate, operators regulate the flow of mortar or plaster out of the drum and into a bucket, hopper, or application tool. When the grate becomes bent, cracked, or worn, material can discharge unevenly or prematurely, reducing batch consistency and slowing the work. Replacing a damaged grate with the correct OEM part restores proper discharge control and keeps the mixer producing consistent results.
