In all instances above, exact cuts are required.Both fittings and straight duct also require tape or screws to secure the connections. Spiral fittings (elbows, branches, etc.) can be made with big end/small end connections and eliminate using collars when joining fittings to the straight duct but collars are still necessary for joining straight duct.Big end/small end collars eliminate this by allowing the collar to be slid into one duct and over the other (in the direction of the airflow) but these are even more expensive- and still require tape or screws. Additionally, this leaves a protrusion in the duct. Not only are these collars expensive, but they also require tape or screws to hold them together. ![]() The collars are typically made to slide into the ends of the joining duct.
