A standoff connector forming, for example, a standoff post base, includes a base member having a first edge and a second edge opposite the first edge. The first edge is configured to include an extending first projection, and the second edge is configured to include an extending second projection. The standoff connector includes a first stirrup plate member that is selectably attachable to the base member at the first edge by inserting the first projection into and through an aperture formed in the first stirrup plate that is sized and shaped to receive the first projection. The standoff connector further includes a second stirrup plate member that is selectably attachable to the base member at the second edge by inserting the second projection into and through an aperture formed in the second stirrup plate that is sized and shaped to receive the second projection.
