Rectangular Offset Ductwork
S-shaped offset section for parallel duct runs. UK-made to DW144, made to order. Instant online price, no account needed.
An offset (S-piece) shifts a duct run sideways or up while keeping it parallel to its original line, stepping around a beam, wall or another run without changing direction. Two opposing bends in one fitting keep airflow smooth.
