Model SRH-BBT Spring Wire-Tie Hanger


Secured to concrete, metal deck, or structural framing, Model SRH-BBT incorporates a one inch (1") rated deflection spring in series with a neoprene element to resiliently support one or more layers of gypsum board. Attachment to the upper eyebolt on the isolator is made via wire suspended from the deck above. Wire is tied on the bottom eyebolt and looped around a piece of 1-1/2" x 1/2" 16-gage steel carrying channel. Drywall furring channel is then attached to the carrying channel. Drywall ceiling grid is another common installation. Gypsum board is connected using industry standard installation techniques. Incorporate Model SRH-BBT into any isolated ceiling design where one inch (1") rated spring deflection is desired, and conditions require the flexibility of using wire.


  • Maximum natural frequency of 4.4 Hz under lightest typical load conditions.
  • Contractor friendly wire-tying feature, convenient for use where wire-tying is the only option.
  • Neoprene element improves performance against low-frequency noise.
  • Actual installed load can vary between 75% and 150% of rated load without significant impact to ceiling performance.
