Square Post Surface Mount Base

Square Post Surface Mount Base

The square post surface mount base is a great choice when you need to install a signpost on concrete or asphalt surfaces and don't want to cut through them to install the post. Two versions are available for 1¾″ or 2″ posts and it is made of galvanized steel for durability. It has four 9/16″ mounting holes in each corner of the base plate for anchoring the base to the ground.

This Square Post Surface Mount Base is designed to hold galvanized square posts up to 8 ft. tall on surfaces like concrete and asphalt.

Each Square Post Surface Mount Base comes with 2 corner bolts and 2 nuts to secure a sign post. It can also be ordered with a concrete anchor kit which contains four 1/2" x 4" lag screws, four 3" plastic anchors, and four 1/2" washers, or it can be ordered with an asphalt anchor kit which contains four 6" anchors, four 1" hex head bolts, 4 washers and 2 bags of concrete based grout.

We do not recommend installing on brick surfaces because they are not a permanent stable surface.
