The telescoping lengths are great for one piece installations from the stove to Dura-Vents Dura/Plus or DuraTech Chimney using a Close Clearance Adaptor. The shorter length allows adjustments from 29 - 48. The longer length gives you 40 - 60 of adjustment. Both pieces must have a minimum of 1 overlap with all connecting pipe. When you are installing Dura-Vent chimney and need reduced clearances on the stovepipe use DVL. It reduces clearances from combustibles to the stove-pipe from 18 down to 6 for walls and 8 for ceilings. It has an inner wall of .016 430-alloy stainless steel and an outer wall of .018 aluminized steel painted black. Connecting pipe sections together is easy with predrilled holes and a pack of screws included. When calculating fit the outside diameter is 1.125 inches larger than inside diameter. Pipe pieces have a 0.75 inch overlap connection reducing the usable length by 0.75 inch.
