ABSTRACT:
A retainer assembly is disclosed for retaining insulation material or the like adjacent a surface, such as an interior furnace wall. The retainer assembly comprises a longitudinally-extending member or stud and a retainer member or washer mounted thereon. The stud includes at least one throat portion. The washer comprises a body from which two prongs extend to define a channel. The prongs are folded back so that as a throat portion of the stud passes therethrough, the folded-back portions are compressed. Upon passage of the throat portions through this zone of the channel, the compressed folded-back portions of the prongs are released from compression thereby retaining the stud within a second zone of the channel.
