The single 7’ post historical markers are manufactured to sit down on top of an octagonal extruded aluminum post that has been provided.  The marker is secured to the post by eight (8) set screws that are provided with the marker.

The post is designed for 36” insertion in the ground.  This leaves approximately 4’ of post above ground.

Using a post hole digger, dig a hole 10”- 12” in diameter and 36” deep.  Place the post in the hole with one of the flat faces on the post facing the direction that the marker is to face.  Place the post in the hole then plumb and brace it. 

Fill top of hole with concrete (sacrete works fine). You might cut the bottom out of a 5 gallon plastic bucket to use as a form. Slip the bucket down over the post so it is resting on the ground at the top of the hole. When you fill the top of the hole with concrete, bring the concrete up about 4 – 6″ above the ground. When hardened, cut the plastic form away and you have a nice curb around the post which will deter mowers and trimmers from damaging the post.

Before trying to place the marker on the post, use an Allen wrench to back the set screws part way out of their holes.  They have been screwed on for shipment and unless they are backed out part way the marker will not sit down on the post.

Place the marker on the post.  Check it for alignment looking straight at the marker and then moving 90 degrees to view the edge of the marker.  Secure the marker by tightening the set screws.  Adjustments in alignment can be made using the set screws.

The marker can be made theft proof by drilling the flats off the set screws after the marker is secured to the post. Simply take a 1/4″ drill bit and drill down into the center of the set-screws going only to the bottom of the hole this will prevent removal of the set screws. To remove the marker, the set screws will have to be drilled out.

Install takes less than an hour; allow 24 hours before removing the bracing.
