Description
The DuraTech Adjustable Length is handy when an exact length of chimney is needed but the standard lengths of chimney do not combine to the needed length. The Adjustable Length spans from a minimum of 14" to a maximum of 22". The Adjustable Length can be used between any other Duratech chimney sections (straight pipe lengths, elbows, tees, etc.). The Adjustable Length is a telescoping section of chimney with both male and female sections. (See figure 1 above). Within the male section there are 2" wide strips of insulation that can be removed to allow for a customized length (See figure 2 above)
