Safety System
The unique flow path generated by the lower and upper waterway pivot points
provides two specific advantages. (1) The two pivot points provide a smoother
waterway transition through its most extreme bends which improves stream
quality. (2) The offset configuration of the two pivot points create a condition
where the reaction force of the water acting on the upper pivot point, if sufficient,
will cause the nozzle to rotate upward about the lower pivot point. This produces
a self correcting increase in nozzle angle to protect against possibly dangerous
unmanned use of the monitor at nozzle angles less than 35 degrees above
horizontal. The hydraulic effect of the Safety System is active at approximately
350 GPM. The Safety System is patent pending.
Hydro-Loc Valve Position Control
The RAM shut off valve utilizes the Elkhart Brass Hydro-Loc mechanism to hold
the valve in a throttled position if desired.
Fully Vaned Waterway
The waterway of the body has a full cast vane to improve water flow and
discharge stream quality.
Inlet / Outlet Configuration
The RAM is manufactured standard with a 2.5” NH thread inlet and a 2.5” NH
thread outlet. Special thread configurations can be addressed upon request.

RAN Straight Stream / Fog Nozzle
The RAN (Rapid Attack Nozzle) is a purpose built nozzle
designed for use with the RAM. RAN is lightweight and
utilizes very few components to deliver water in both
straight stream and fog pattern. Significant to the stream
quality of the RAN is its integral stream shaper. The RAN
delivers 500 GPM at 75 psi and 400 GPM at 50 psi. The
RAN is manufactured standard with 2.5” NH threaded
swivel. Special thread configurations can be
addressed upon request.
1-3/8” Discharge Smooth Bore Nozzle
Elkhart Brass offers a 1-3/8” discharge smooth bore
nozzle which will provide 500 GPM at 75psi. The
nozzle is manufactured standard with 2.5” NH
