Just like they sound, these flanged end reducers narrow to allow you to connect to a smaller pipe. The tapered duct is spot welded and caulked with flange ends.

We have used Carolina Air Systems for several years now with both new installation work and with plant modifications to the existing system. We have been very pleased with the dust pipe quality and their installation crew. Also we are pleased with the Snap-It product because it makes it very easy when we have to move our machinery. We are very pleased with the products and service work Carolina Air does for RSI.
