FENO Polyrock Heads
FENO Polyroc monument blocs provide a large, easy to see head for the top of the mark. Ideal for
marking cemetery corners, rights-of-ways, and survey corners where visibility is key.
Available in red, white, or yellow for the 350mm, 600mm or 1000mm spikes.
To use simply drive the FENO spike through the Polyroc Head when setting the mark.
