The Sanitaire SC887 & SC689 Dirt Cup Support (part 545611) is an original equipment manufacturer assembly component that secures the bagless dust collection system in Sanitaire SC887 and SC689 commercial upright vacuums. This support framework maintains proper positioning of the 1.9-quart dust cup capacity and enables the quick-release latch mechanism that allows the dust cup to pivot away for emptying.

Constructed from durable commercial-grade materials, this dirt cup support assembly withstands the demanding requirements of professional cleaning environments. The precision-molded housing maintains structural integrity under regular commercial use while ensuring proper seal alignment between the dust cup and motor housing for optimal suction performance.

This OEM part 545611 is specifically engineered for compatibility with Sanitaire models SC887, SC689, SC684, SC886, SC888, and SC889 commercial uprights. The SC887 features a 7-amp motor with 145 CFM airflow and 50-foot cord, while the SC689 operates with a 5-amp motor, 120 CFM airflow, and 30-foot cord. Both models utilize the same dirt cup support assembly configuration for consistent serviceability across the commercial upright series.
