Add a classic look to your deck stairs with Trex Select Stair Railing kits, which extend the high-contrast look of Trex Select deck railing to your stair sections. White composite rails deliver a traditional style and round black aluminum balusters slide easily into place.

Trex Select Stair Rail kits come with a top rail, bottom rail, brackets, balusters, a foot block, and all the hardware you'll need to complete your stair railing section. Rail brackets fit stair angles from 32 to 37 degrees. Sold separately: post sleeves to go over existing wood posts or structural posts.

Choose between two rail heights: 36-inch or 42-inch. Trex Select Stair Railing kits are sold in 6-foot and 8-foot lengths that you can cut down to fit your stair sections.
