The Pittsburgh seam is the ideal seam joint on straight or bent ducts made of
pre-formed pinned together border profiles. Aesthetically pleasing and solid fittings are produced without having to use additional fitting elements. The seam locker F 300 i.e. F 301 will lock Pittsburgh seams by a self acting almost silent roll / sliding process without damaging the surfaces or metal coatings. The integral feed ensures constant seam accuracy and high quality of the seam lock.
