Description
Reliable Models G & F1 Open Sprinklers are similar in design to Reliable Models G & F1 Automatic Sprinklers except they are not equipped with fusible or frangible element parts, and therefore, do not operate automatically. They are installed in locations where a blanket of water is desired over a predetermined area.

Open Sprinklers are available in four types: Standard Upright, Standard Pendent, Conventional. and Sidewall.
All Open Sprinklers are available in the following finishes: Plain Bronze, lead plated wax coated or wax coated over lead plated, Electroless Nickel PTFE plated. No waterway protection is provided. Consult factory for other finishes. The following table lists Reliable Open Sprinklers by type, orifice size, pipe connection size, overall length, installation position and SIN. Installation positions other than the design installation position shown in the table may be used. However, the resulting distribution pattern in the installed position must be carefully considered.
