Steel Foundation Sleeves with Base Plate and Ground Spike

Galvanized Steel Foundation Sleeves

The most common type of flagpole installation is the in-ground foundation sleeve method which calls for 1' of the flagpole to be encases in the ground sleeve for each 10' of the exposed flagpole height. The diameter of the sleeve should be at least 2' greater than the outside diameter of the flagpole with the area between and the sleeve filled with dry sand. Sleeves with a 6" diameter are supplied with a base plate, support plate, grounding spike and, for ease of vertical alignment, steel centering wedges welded to the inside of the base plate.
