Fig 818 Alternate Adjustable Support Roller

APPLICATION: A Fig. 818 Alternate Adjustable Support Roller is used to support piping 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 immediately below the piping and 3.) limited vertical adjustment of the pipe roll is necessary or desirable.

An Alternate Adjustable Support Roller allows axial movement of the piping with virtually a negligible amount of frictional resistance to the movement. Vertical adjustment is achieved by changing the elevation of the adjustment nuts above and below the structural member to which the support rods are attached. Vertical adjustment is limited to the threads on the support rods.

CONSTRUCTION: A Fig. 818 Alternate Adjustable Support Roller consists of a Fig. 806 Cast Iron Pipe Roll, a carbon steel roll rod bent on both ends to provide vertical legs for support and four nuts.
NOTE: See size selection chart for assistance in determining the appropriate Alternate Adjustable Support Roller for your application.
FINISHES AVAILABLE: Black, Hot Dip Galvanized, Electro-Plated or Painted.
ORDERING: Specify figure number, pipe roll size, name and finish, of other than black.
