Floor-Mount Strut-Style Supports



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 supports have a 1-5/8" wide strut channel for use with strut-mount clamps.
Style B supports have a roller that allows pipe and duct to move—good for HVAC systems where vibration is present.
Style C supports have two bases for additional stability and a 1-5/8" wide strut channel for use with strut-mount clamps.

Roller 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.

Adjustable-Height Floor-Mount Strut-Style Supports


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