Woodstock W1041 - 3" to 2-1/2" Combination Adapter

2-2/12-inch by 3-inch outside diameter. 3-3/16-inch length by 3-inch width by 3-inch diameter. These fittings provide a step down from a larger main line to smaller branch lines. This step-down increases air velocity near the machine where it's needed most. These three size reductions will handle most system needs.
