Reliable JL14-JL17 ESFR Pendent Sprinkler

This is an ESFR sprinkler head family designed for medium and high-rack storage applications. Storage height, ceiling height, and the type of stored material determine which K-factor should be selected. In ESFR systems, the clearance between the ceiling and the top rack and the arrangement of racks are part of the design; subsequently raising the racks invalidates the system.
