Dust Collection Port Cap for 4" O.D. Ports

Please note that this product is the 4" OD dust collection port cap only.We have all made a mess with tape and cardboard to cover an open port in our dust-collection systems. This simple cap slides over the 4" OD port of most fittings and machines to prevent air leaks in the system.
