Place the rail onto the porch in the location you're installing it.
Mark the holes for the bolts in the railing onto the porch, then remove the railing.
Drill pilot holes into the porch, using a hammer drill that has a masonry drill bit.
Remove the bolts from the concrete sleeve anchors.
Insert the sleeve anchors into the pilot holes until they are flush with the surface of the porch. Tap them gently with a hammer, if needed.
Place the railing into position, aligning the holes in the railing with the pilot holes. Drive the bolts into the anchor sleeves with a socket wrench. Do not overtighten the bolts because you can break the anchor sleeves.
Paint the heads of the bolts to match the railing.
