Abstract
A hanger assembly for securing insulation or refractory linings to walls includes a circular stud which includes a flattened locking section of relatively short axial extent forming laterally projecting lugs, a somewhat less flattened anti-rotation section of substantial axial extent inwardly adjacent the locking section, and an unflattened or rotation section of short axial extent inwardly adjacent the anti-rotation section, whereby a quarter-turn retaining washer may be positioned over the stud to the rotation section, rotated a quarter turn and then moved outwardly along the anti-rotation section to engage and lock against the underside of the locking section. The locking and anti-rotation sections may be repeated throughout the length of the stud by a selective flattening of round metal stock so that insulation layers of various thickness may be held to the wall without the possibility of vibration permitting the retaining washer to vibrate free of the locking section, rotate, and become disengaged from the stud.
