FENO F350SPK Drive-in Spike Survey Marker

FENO Spike Length: 350mm (13.77 inches)

The FENO anchored survey mark system offers a unique solution to surveyors who want to use a small, easy to drive quality galvanized steel survey mark. The unique FENO concept holds that in order to guarantee both the correct position and also the secure placement of marks, two conditions must be fulfilled: 

(1)   It should be possible to move a temporary mark into a permanent position. If the marker is fitted with wings or lugs (or any other type of anchoring device) this is not possible. However, with the FENO system, the position of the marker can be easily changed at any time prior to the extension of the anchor prongs.

(2)   Once the marker has been finally positioned, it must be possible to lock the marker firmly and securely in the ground. With FENO markers, when the correct position has been achieved, the strong steel prongs can be extended to secure the marker into position, much like the roots of a tree.

Easy to Use

Using a hammer and inexpensive driving and fixing tools the marker can be installed in all soil types.  Eliminates digging a hole or mixing expensive concrete.  Strong steel pins curve and lock securely in the ground and stay put.  A FENO marker can be installed in just minutes.
