A division of BackFlow Armor
This is a green dyed - concrete donut for sprinkler heads. They come in two sizes (spray head size and rotary head size). The purpose of the donut is to displace the weight ofa vehicle or lawn mowers tire. This will aid in the protection of the sprinkler head and the pipes below the head.
These donuts are made out of fiber reinforced concrete for maximum strength and durability. They are tapered on the outer side of the donut to aid in the weight displacement. The outer bottom edge measures 7.5” and the top outer edge measures 6.25”. The entire concrete mixture is green.
It is shipped throughout the continental United States!
