RC-729A — Adjustable Roll Support
Designed for longitudinal movement of pipe where vertical adjustment is
required. Although primarily used for support of the pipe, this component
may also be placed over the pipe to act as a guide.
• Material: Cast Iron Pipe Roll and
Sockets with a Carbon Steel Axle.
Do not exceed 450° F/232° C at the
contact point to the roll.
• Compliance: A-A-1192A Type 42,
MSS SP-69 Type 41.
• Finish: Black (add suffix “-B”).
Electro-Galvanized (add suffix “-HDG”).
For pipe with insulation and a pipe
covering protection saddle, the
RC-729A will have to be oversized
to suit.
Please see the table below which
shows the correct sizing for
insulated pipe.
