• Secure Drum Engagement — A properly functioning lock pin unit keeps the mixer drum locked firmly in the correct operating or discharge position, preventing unintended movement during use.
• Authorized OEM Source — Sold by DHS Equipment, an authorized Multiquip dealer, so you receive a verified, current-production OEM part with the correct part number.

The lock pin unit on a plaster and mortar mixer is the mechanical fastener that locks the mixing drum in place during operation or holds it at the correct angle when discharging material. Without a fully functional lock pin, the drum can shift unexpectedly during mixing, compromising batch consistency and creating a safety hazard for the operator. A worn or damaged lock pin unit should be replaced promptly to restore proper drum control and keep the mixer operating as intended.
