Floor-Mount Strut Pipe Supports


Style A	Style C

Reduce noise caused by HVAC systems. These sturdy rubber supports isolate vibration caused by heat pumps and air conditioning units, resulting in a quieter facility. When used on roofs, they also keep components above puddled water, which can cause damage. Supports have integrated strut channel that works with strut fittings and strut-mount routing clamps to organize and secure duct, pipe, tubing, and conduit.

Style A—Style A supports have a 1 _5/8" wide strut channel.

Style C—Style C supports have two bases for additional stability and a 1 _5/8" wide strut channel.

Height-Adjusting Floor-Mount Strut Pipe Supports


With Strut Channel	With Strut Channel and Loop Hanger

Adjust supports to the exact height you need to route pipe, conduit, and tubing through strut-mount routing clamps and hangers. The wide base provides stability without needing to permanently secure to the floor. Supports have a 1 _5/8" wide strut channel for use with strut-mount clamps and hangers.

Loop Hanger—Use supports with strut channel and loop hanger to suspend material such as pipe, tube, and conduit.

Roller Pipe Supports

Support lines that expand and contract. The roller on these supports compensates for movement in your line from changing temperatures. Often used outdoors, these supports are galvanized steel to resist corrosion in wet environments. Bolt them to the floor, beams, or brackets. They can also be welded into place.

Floor-Mount Saddle Pipe Supports

These U-shaped supports allow access to pipe and conduit after installation. Use them to suspend pipe, tube, and conduit above the floor. To install, add an extension pipe (not included) that is approximately 4" shorter than the desired height. Tack weld pipe to the base and support, then bolt the base to the floor. Fine-tune the overall height using the adjustment screw.

Galvanized Steel—Galvanized steel supports have good corrosion resistance.

304 Stainless Steel—304 stainless steel supports have excellent corrosion resistance.

Floor-Mount Flange Pipe Supports

Bolt these supports directly to a pipe flange to suspend a run of pipe above the floor. Unlike clamps and hangers, which fasten to walls and ceilings, these supports mount to the ground. To install, add an extension pipe (not included) that is approximately 4" shorter than the desired height. Tack weld pipe to the base and support, then bolt the base to the floor. Fine-tune the overall height using the adjustment screw.

Floor-Mount Clamp Pipe Supports

For a secure hold on pipe and conduit suspended above the ground, these supports have a cushioned clamp that provides a 360° grip while reducing vibration. To install, add an extension pipe (not included) that is approximately 4" shorter than the desired height. Tack weld pipe to the base and support, then bolt the base to the floor. Fine-tune the overall height using the adjustment screw.
