The Innerduct Seal is a screw-in type that requires one product for each duct size. The second type is a Universal Seal which is a tapered product suitable for all duct sizes from 1" to 2". This is for use on short distance blowing where simply holding the seal against the end of the duct will do the job and save time. The Innerduct Seal Kit Comprises all four Innerducts seals plus the Universal Seal. A Control Valve and Rope Guide are also included.
Kit Includes: 1 Universal Innerduct Seal Kit with 4 Innerduct Seals, Control Valve and 1 Universal Seal
