Pipe Supports
Three types of pipe clamps are available to provide right angle, vertical and parallel attachment to a
beam. Types RC, EC and PC are malleable iron clamps with an edge that grips the structural member
for maximum holding power when tightened.
Type RCS clamps are all steel, providing two bearing surfaces for strong attachment for mounting pipe
or conduit at right angles to the beam.
All parts are electrogalvanized, including the threads. The clamps are designed for clamping to a wide
variety of beam thicknesses and tapers. Can be installed using only a wrench.
• RC Clamp —
Malleable Iron
• RCS Clamp — Steel
• For mounting pipe or
conduit at right angles
to the beam
• Use SS316 suffix for
316 Stainless Steel
• Use HDG suffix for
hot-dip galvanized
• PC Clamp —
Malleable Iron
• For mounting pipe
or conduit parallel
to the beam
• Use SS316 suffix for
316 Stainless Steel
• Use HDG suffix for
hot-dip galvanized
