DuraVent DuraTech Locking Band: an optional clamp for chimney joints
The DuraVent DuraTech Locking Band is a metal band that adds a hold around a chimney connection. It clamps where pipe lengths meet, or at an elbow that turns the chimney or a tee that branches off it. The joint already locks with a twist and needs no band or screws, so most chimney runs can go without this extra piece. You might add one on an outdoor stretch exposed to wind, or if your local inspector requests it. DuraTech is DuraVent’s double wall chimney, an insulated pipe with a 1 inch wall that takes over from the stovepipe at the ceiling or wall and runs up past the roof.
Choose a 5, 6, 7, or 8 inch diameter on this page to match your DuraTech chimney. Allow one band for each connection you want to secure. This band is for DuraTech only, not DuraPlus, DuraChimney, or another chimney line. Those systems cannot be mixed with DuraTech parts. Need the lengths this band joins?
