Fig 821 Pipe Roller Chair

“APPLICATION: A Fig. 821 Pipe Roller Chair is used to support pipe where 1.) significant movement along the axis of the piping at the support location occurs due to thermal expansion or contraction of the piping, 2.) support is to be provided from a beam or other structural member located directly below the piping and 3.) vertical adjustment of the pipe roll is not necessary.

A Pipe Roller Chair allows axial movement of the piping with virtually a negligible amount of frictional resistance to the movement. Vertical adjustment can only be achieved by shimming under the Pipe Roller Chair at the time of installation. A Fig. 821 Pipe Roller Chair may be bolted or welded to the supporting structural member.

CONSTRUCTION: A Fig. 821 Pipe Roller Chair consists of a Fig. 806 Cast Iron Pipe Roll, a threaded carbon steel rod with a hex nut on each end, a heavy steel chair and two hold-down bolts in the chair.
NOTE: See size selection chart for assistance in determining the appropriate Roller Chair for your application.
FINISHES AVAILABLE: Black, Hot Dip Galvanized, Electro-Plated or Painted.
ORDERING: Specify figure number, pipe roll size, name and finish, if other than black.
