HRS-PR Pre-Compressed Spring & Elastomeric Hangers are designed to isolate low and high frequency vibrations in suspended piping and equipment - preventing transmission of vibration to the building structure through the piping systems.  The products incorporate a color-coded steel spring for ease of identification in the field. Load ranges from 21 - 8,200 lbs. and up to deflections of 3". Custom sizes and deflections up to 5" available upon request.

VMC Group pre-compressed designs are pre-compressed to the rated deflection so as to support the suspended equipment or piping at a fixed elevation during installation regardless of load changes.

The HRS-PR Precompressed Series also offers the capability to incorporate eyebolt hardware to accommodate duct strap connections and/or pencil rods, when isolating ductwork and suspended ceilings.

Features & Benefits

  • Loads from 21 - 8,200 lbs. with static deflections up to 3” provide flexibility over a wide range of applications
  • Pre-compressed hangers offer quick and easy installation for a fixed elevation in even the most challenging locations
  • Color-coded springs provide easy identification of spring hangers for installation and inspection
  • Combined elastomeric and spring for both low and high frequency isolation in one hanger box

Applications

  • Suspended piping
  • Suspended electrical services
  • Suspended equipment
  • Suspended ductwork
