Adjustable Swivel Pipe Roll (Patented October 4.1921) Fig. No. 174 HTHE Adjustable Swivel Pipe Roll supplies the need for any ad. justable type of pipe roll hanger with single hanger rod. It is unique inasmuch as vertical adjustment can be made by use of the swivel shank at the top of the hanger. Branch Pipe Rolls /GRINNELL Pipe Rolls are especially designed to take care of expansion and contraction. The rolls are made hollow so that only-a small surface is in contact with the rod whereas the surface in contact with the pipe is made as large as possible. This results in the "roll" actually rolling when expansion or contraction of piping takes place. Through a specially designed socket, vertical adjustment is allowed at the bottom of each vertical rod as well'as at the Ceiling Flange. Furthermore, the nut at the bottom of the hanger rod fits into a recess of the socket preventing loosening or turning from vibra tion.
