YES. Semi-rigid flexible ducts can be easily cut to length without the need for special tools. The cutting process involves marking the duct where you want to cut, using a hand tool like a utility knife, scissors, tin snips, or specialized duct shears for clean cuts. Power tools such as circular saws, jigsaws, and reciprocating saws can also be used for larger diameter or thicker ducts. Proper safety precautions should be followed, and cuts should be square and smooth to prevent air leakage.
