HARRISON MARKERS
PERMANENT
They are cast iron- the proven metal, they won’t disintegrate underground like aluminum or wood.
MAGNETIC
The are easily located no matter the depth and a dip-needle or electronic sensing device responds strongly.
STABLE
They are secure in all soils, resist side and pull-out thrusts and if accidentally struck, the top will crack off while the bottom maintains its position.
ECONOMICAL
Cast iron is abundant and low in cost.
Harrison Marker Styles
The Standard Harrison.
The Standard Harrison comes in the largest variety of sizes to meet the widest possible range of needs- tall, short, straight, and flared. The Standard Harrison is ideal for perpetuating original government corners.
The Extendible Harrison.
The Extendible Harrison works when your mark needs to be permanent and always flush and visible. When the surface height increases, just twist off the top and add spacers and/or legend tops as needed. The marker can be extended- even in 1” increments. No pavement is destroyed. No resurveying is necessary. There is no need to re-establish the point again.
The Slimline Harrison.
The Slimline Harrison has a smaller diameter of 2 3/4”, making it lighter for easier carrying and handling. The Slimline is cost-effective and It’s versatility can be used in any survey situation but is most commonly used for lot and subdivision surveys.
