Metal-Fab Adjustable Type B Round Chimney Pipe Length - 4" x 12" - 4M12A

The Metal-Fab Adjustable Chimney Pipe Length uses the SureLock system to secure two venting pipes with an easy twist and lock. This system does not require any tools and SureLock makes it almost impossible for the pipes to come apart. The Metal-Fab Pipe Length is compatible with many different pipes so you don't have to replace your entire vent for only one pipe. The double-wall design needs only a 1" clearance, which makes it convenient for even small homes. The Metal-Fab Adjustable Chimney Pipe Length is a safe and easy way to secure your vent line.
