  The Gate Column wraps to an existing structural post, acting as a latch jamb to the the Garden Gate on the left, and a hinge jamb to the out-swinging Driveway Gate.  The Column arrives as a three-sided unit, slipping around the post, with the fourth side secured in place as a simple last step to the installation.  

Often, the gates are installed prior to any pending stone or walkway work, as a precaution against potential mishaps by an inwitting crew.
