Key Features

• OEM-Grade Retention Strength — Built to the same holding and latch-engagement specifications as the original, so the drum grate closes and stays secured under working loads.
• Direct Drop-In Replacement — Matches the original mounting points and hardware interface on EM120P Series, EM120S Series, WM120PH, and WM120SH mixers for a straightforward swap.
• Broad Mixer Compatibility — Fits both Essick and Whiteman 120-class plaster and mortar mixer models, covering a wide range of units in a single part number.
• Maintains Drum Access Control — A functioning grate latch keeps the drum grate properly secured during operation, preventing unintended opening and protecting material consistency throughout the mix cycle.
• Operator Safety Compliance — The drum grate and its latch mechanism are a critical safety barrier during operation; using a genuine OEM latch ensures the closure mechanism performs as originally engineered.

The grate latch is the mechanical fastener that holds the drum grate closed on plaster and mortar mixers during operation. It keeps the rotating drum sealed against accidental opening, protecting both the operator and the material being mixed. When the latch wears out, becomes bent, or fails to engage properly, the grate can shift or open unexpectedly — creating a safety hazard and interrupting the mix cycle. Replacing a worn latch promptly restores the secure, reliable closure the mixer was designed to operate with.
