sprinklers when protecting high-piled
storage.
Model ESFR-17 Pendent Sprinklers are
primarily used for ceiling-only sprinkler
protection of, but not limited to, the fol-
lowing storage applications:
• most encapsulated or non-encap-
sulated common materials including
cartoned, unexpanded plastics
• cartoned, expanded plastics
• uncartoned, unexpanded plastics
• uncartoned, expanded plastics
• some storage arrangements of
rubber tires, roll paper, and aerosols
