Ask & Answer
Metal-Fab's Adjustable Chimney Pipe Length is ideal for the homeowner who wants the most from the least. Its advanced dual-wall construction maximizes both space and efficiency, requiring only an inch of clearance to combustible materials. Metal-Fab's innovative SureLock system allows you to create a secure vent connection with no tools, at a fraction of the time and cost: the pipes simply fit together, twist, and lock with the push of a button. It's adaptable, adapting with a variety of other brands of vent pipe with no specialty adaptors. This Chimney Pipe Length adjusts from 3" to 14", and includes a limited 1 year warranty.
* Please Note: Pipe overlaps 1.5" when joined together. Therefore, the assembled length is 1.5" less than listed.
