Multiquip EM507421 Dump Latch

The Multiquip EM507421 Dump Latch is a genuine OEM component designed for Essick and Whiteman concrete and mortar mixer models, including the EM-700S, EM-700P, EM-900S, EM-900P, WM-700S, WM-700P, WM-900S, and WM-900P. Sourced directly from Multiquip, this latch is an exact match to the original hardware installed at the factory, ensuring correct fit and function with no guesswork. If your mixer drum is no longer locking securely in the upright or dumping position, this is the part that restores safe, reliable drum control. DHS Equipment supplies this genuine OEM replacement so you can get your mixer back to work with confidence.

Key Features

• Genuine OEM Construction — Manufactured to the same material grade and dimensional tolerances as the original latch, ensuring consistent engagement and hold under repeated drum cycling.
• Direct-Fit Replacement — Matches the original mounting points and latch geometry on Essick and Whiteman mixer drums, dropping into place without modification.
• Broad Mixer Compatibility — Fits EM-700S, EM-700P, EM-900S, EM-900P, WM-700S, WM-700P, WM-900S, and WM-900P mixer models across the Multiquip portfolio.
• Drum Control Restored — A functioning dump latch keeps the drum locked at the correct angle during mixing and releases cleanly during pour — a worn latch causes uncontrolled dumping and material loss.
• Operator Safety — The dump latch is a critical retention component; replacing a damaged or worn latch prevents unexpected drum movement that can pose a hazard to operators and nearby workers.

The dump latch is the mechanical retention device that holds the mixer drum in position during both the mixing cycle and the controlled pour. When the operator is ready to discharge material, the latch releases the drum and allows it to rotate to the dump angle; once emptied, it locks the drum back into the mixing position. A worn, bent, or broken latch will fail to hold the drum securely, causing it to drift or drop unexpectedly — disrupting the pour, wasting material, and creating a safety risk on the jobsite. Replacing the latch with a correct OEM part ensures the drum engages and releases exactly as designed throughout the machine's service life.
