Neoprene Hangers
Effective Isolation for Piping or Suspended Equipment
Series QRH and QRHD hangers are molded in colored oil resistant neoprene. This unique color coding make it easy to identify capacity, simplify stocking, and prevent installation errors. Hanger elements can also be molded in other elastometers to meet specific requirements.
- Available in 4 sizes - 5 Durometers
- Load Range - 10 lbs. to 4,000 lbs.
- Deflections to 1/4" with type QRH / to 1/2" with type QHRD
- Molded in colored oil-resistant neoprene
- 5 colors for error free identification
Typical Applications
- Air Handling Units
- Fans
- Piping
- Suspended Ceilings
To Specify:
Vibration hangers shall consist of a steel housing and isolation element molded entirely of colored oil-resistant neoprene stock for easy identification of capacity. The hangers shall be the double deflection type "QHRD" as provided by QWYATT Noise Control, New York, NY.
