Dean Column 3-1/2 in. x 8 ft. Lally Column

The embedded fastening unit is made up of a 6 in. anchoring bolt threaded into a 1-1/4 in. coupling nut, which is embedded in the concrete. A welded steel disc finishes the top of the column. This column has the same strength as our old style but has an embedded fastening unit in the top of the column.
