Victaulic
This Model V27 conventional old-style sprinkler is designed to produce a hemispherical pattern which deflects approximately half of the spray upwards toward the ceiling and the other half downwards and can be installed in either the upright or pendent position. It is available with either standard or quick response bulbs. It is cast with a hex-shaped wrench boss to allow easy tightening from many angles, reducing assembly effort.
This sprinkler is available in various temperature ratings and finishes to meet many design requirements.
