Position and attach the first of the purchased mounting plates to fix the stair railings to the porch columns. The rear surface of the plate has a concave surface that fits against the rounded/convex surface of the porch columns. Markings stamped on the plate indicate the upper end and the center of the plate where you will drive a single screw to secure the plate to the column, but you should mark the center of the plate and a base line for the railing bracket base added in the next step. Repeat this step for the other three mounting plates.
Position and secure the purchased railing bracket bases on top of the mounting plates for the upper and lower rails of each stair rail section.
Insert plastic plugs provided to conceal the screw holes and keep water out.
