HS Series Spring Hangers are designed to isolate low 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 offers pre-compressed, 30° angularity and pre-positioning hangers. Our 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  angularity hangers have a 30° misalignment capability, spring diameters and hanger box lower hole sizes are sufficiently sized to permit the hanger rod to swing approximately 30° before contacting the box. Pre-positioning hanger designs incorporate a means for supporting the suspended equipment or piping at a fixed elevation during installation regardless of load changes as well as a means for transferring the load to the spring.

The HS 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 and pre-positioning hangers offer quick and easy installation in even the most challenging locations
  • Lower hanger rod on some models enables a 30⁰ swing to compensate for rod misalignment and prevents short circuits to the hanger box
  • Color-coded springs provide easy identification of spring hangers for installation and inspection

Applications

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