Concealed Pendent Sprinklers
The SHIELD Sprinklers, SD1050, SD1055 (Glass Bulb Type) Standard and Quick Response Concealed Sprinkler, design incorporates state-of-the-art, heat responsive, frangible glass bulb design for prompt, precise operation. The die cast frame is more streamlined and attractive than traditional sand cast frames.
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.
The recessed pendent should be utilized with a recessed escutcheon which provides up ½” of adjustments. All sprinklers are manufactured using the time proven Belleville seal used exclusively by all major manufactures to ensure long life and safe operation.
