Stafford Manufacturing Corp. is marketing its new line of shaft collars that are designed for securely mounting shafts or tubing to a flat surface without marring or crushing. Accu-Flange collars feature a perfectly square integral flange with drilled and tapped through-holes and a clamp-type collar for rigidly attaching shafts or tubing to a flat surface. The new mounting collars are designed to maintain their perpendicularity and not mar shafts or crush tubing and afford builders virtually unlimited design flexibility.
