DEFLECT-O DEFLECTO DRYER DUCT SPRING 4" CLAMP MSC4100

The Deflecto MSC4100 is a 4-inch spring clamp designed for securing dryer duct connections quickly and reliably. The spring tension automatically creates a constant-pressure seal that accommodates slight duct movement without loosening, preventing exhaust leaks that reduce dryer efficiency and create fire hazards. Compatible with standard 4-inch flexible and rigid dryer duct.
