Shop Fox D4866 Dust Fittings 4" to 4" x 4" x 4" Double Branch New

The Shop Fox D4866 is a 4-inch double branch dust fitting designed to split one dust collection line into two branch lines. It helps connect multiple machines to a single system while maintaining smoother, more efficient lateral airflow than many standard fitting styles.

Its double-branch layout lets both branches turn off from the original direction of the main line, making it a practical choice for organizing shop duct runs. Made with an anti-static additive, it is well suited for woodworking and other workshop dust collection setups that use 4-inch hose or pipe connections.
