DESCRIPTION AND OPERATION
The complete connection is made from a high quality bronze with polished ball bearing swivel connectors. It is intended for installation on the exteriors of buildings having standpipe and hose or sprinkler systems to enable the Fire Department to connect hose lines directly into the system to supplement existing water supplies.
The straight way design enables either one or two hose lines to be connected, as the bronze clapper will close on the unused inlet or position itself in the middle when both inlets are used.
The outlet connection has 4" N.P.T. threads and the connectors have 2 1/2" National Standard Hose Threads. Other hose threads may be obtained upon special order.
The Fire Department Connection must be installed according to current NFPA 13 and with the authority having jurisdiction.
The connection should always be installed with a wall plate, ball drip, and breakable caps or plugs.
