DuraBlack single-wall stovepipe completes the venting system when used with one of Duravent's chimney products, such as DuraTech, DuraPlus, or DuraPlus HTC. For an economical, drip-free, single-wall stovepipe, DuraBlack is an excellent choice. Built to Duravent's high standards, DuraBlack is constructed with die-formed end fittings. Adjustable lengths eliminate the need for cutting and crimping.
