Convert Dust Ports from Millimeters to Inches

Every shop owner knows the frustration of struggling with a tool connection, only to find that you're trying to mix inches with millimeters. Oneida Air Systems offers this convenient adapter fitting that is constructed from heavy-gauge, galvanized steel and is pre-crimped on the 6" end for simple installation into existing ductwork layouts. The raw (uncrimped) end is designed to slip over the 120mm sized dust collection ports of imported tools, and features a long-tapered design that minimizes air resistance.
