The new single-wall vent pipe from Metal-Fab snaps together without tools. Available in 3-, 4- and 5-inch diameters, the Corr/Guard Single Wall Special Gas Vent is designed for fast one-step connections, according to the company. The gas vents are pushed together until the snap-lock tabs click into locked position. The company says that the snap-lock tabs ensure the connection will not leak condensation water or pressure, and won't sag on horizontal runs.
