Choose a dedicated full-circle Falcon 6504 for large turf areas that need watering in every direction. The 6504FC has the standard black cover, while 6504FCNP has a purple cover for non-potable water identification. Both options use a plastic riser and provide fixed 360° rotation in one direction, with a SAM check device to help limit drainage after shutdown.

• Choose standard black cover or purple non-potable cover.
• SAM check device holds up to 10 feet of elevation head.
• Water-lubricated gear drive and stainless steel retract spring.
• Radius adjustment allows up to 25% reduction without changing the nozzle.

Common Uses

• Open centers of parks, athletic fields, school grounds and other large turf areas.
• Non-potable turf irrigation requiring a purple identification cover with the FCNP option.

Compatibility & Installation Notes

Match the 1-inch NPT bottom connection and confirm enough depth for the 8-1/2-inch retracted body. Select nozzle and spacing from the standard Falcon performance chart using the pressure available at the head.

The gallery shows the Falcon family, including a nozzle display and cutaway. Those illustrations do not mean a nozzle assortment or stainless steel riser is included with either listed FC option.

Choose a PC model where a limited arc is required. The FC model cannot be set to a half-circle pattern using the arc instructions for PC units. The purple cover identifies non-potable water; it is not a treatment or backflow-prevention device.

Over the years, a select few products have risen above the rest with their unparalleled performance. We’re thrilled to share these gems with you. Whenever you spot the “From the Frog” badge, rest assured it’s more than just a mark of quality—it’s a symbol of our dedication and careful consideration in choosing the best for you. 

Frequently Asked Questions

What is the difference between 6504FC and 6504FCNP?

Both are plastic-riser full-circle rotors. The 6504FC has a standard black cover; 6504FCNP has a purple cover for non-potable water identification.

Can these be set to a half circle?

No. These FC models operate in a fixed 360° circle in one direction. Use a Falcon PC model for an adjustable arc.

Are watering nozzles included?

These F4FC/F4FCNP configurations are identified by Rain Bird as less-nozzle models. Select a suitable Falcon nozzle separately; the gallery nozzle display is a family illustration.

What does the SAM device do?

It holds up to 10 feet of elevation head to help limit low-head drainage after the irrigation zone shuts off.

Why Buy from Big Frog Supply?

Choose the FC version for a central turf position that needs continuous 360° coverage, then choose the cover for the water source: black for the standard model or purple for non-potable identification. The 10-foot SAM capacity helps assess sloped zones, while separate nozzle selection lets you match flow and throw to the available supply.
