A protective cover for a column base connector having a lower portion set in a body of concrete and an upper portion in the form of spaced-apart, upstanding, first and second flanges extending upwardly from an upper surface of the body of concrete, each one of the first and second flanges defining a respective one of first and second flange bolt holes for use in bolting a column to the column base connector. The protective cover takes the form of an inverted pot having a lower edge and a size such that the inverted pot fits over the upper portion of the column base connector with the lower edge atop an upper surface of the body of concrete. The inverted pot includes a first side that defines a first cover bolt hole disposed in a position to align with the first flange bolt hole, and a second side of the inverted pot opposite the first side that defines a second cover bolt hole disposed in a position to align with the second flange bolt hole. In one embodiment, the inverted pot is shaped as a truncated rectangular pyramid, the first and second cover bolt holes are vertically elongated slots.
