Metalbest 4DT-TL38B 4x22 Inner Diameter Direct-Temp Direct Vent Pipe

Pipe lengths provide the core part of the chimney system. Pipes should match the inside diameter of all other pieces and all pieces should be from the same manufacturer. This telescopic length adjusts from 38" to 70" in length. Direct-Temp system features stainless steel inner and heavy duty galvanized steel outer walls. Heavy duty centering brackets keep inner pipe centered and chamfered edges allow for easy slide-together assembly. The free-floating inner liner allows the pipe to expand and contract under high temperature, without creating gaps or stress points. The LockTab is a unique design that allows for 360 rotation while securely locking the sections of pipe together with just a push of the tab.
