HRSA-PR Series Pre-compressed Spring & Elastomeric Angularity 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.
The VMC Group HRSA-PR Pre-compressed Spring & Elastomeric Angularity Hangers combine both a pre-compressed feature along with 30° of angularity for misalignment of hanger rods. The 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.
The HRSA-PR Pre-compressed Series also offers the capability to incorporate eyebolt hardware to accommodate duct strap connections and/or pencil rods, when isolating ductwork and suspended ceilings.
