• Highlight: Unger 11MQC is a quick-connect socket designed for the HTKI4 telescoping pole system — converts compatible Unger pole ends into the universal quick-connect interface.
• Best For: Window cleaning crews and high-reach janitorial teams running the Unger HTKI4 platform who need to swap tool heads (squeegees, washers, dusters, scrapers) without unthreading.
• Expert Note: Quick-connect on the Unger system is held by spring-loaded ball detents, not by friction — fully insert the male coupler until it clicks past both detents before flipping the lock collar.
