Use a chop saw to cut the railing sections to length. When you mark the length on the railing section, center it so that you leave the same amount of rail on both ends without cutting into a baluster.
Fit the cut ends of the rails with end brackets.
Position each rail assembly in the span between the column and the post, lowering it so that the cleats engage with the end brackets to hold the rail securely in position. Tap the top of the railing several times with the palm of your hand to ensure that it seats properly.
Install a rust-resistant screw into the bottom of each end bracket to lock each railing assembly in position.
Apply glue to the interior lip of the remaining post caps and set them in place.
