Measure the angle and length for the top and bottom handrails. Cut 2x4 pressure-treated lumber for the handrails, making angled cuts at each end to match the stair pitch. Pre-drill holes in the handrails for the 3/4-inch round aluminum balusters. The spacing between balusters should be 4 inches, which translates to approximately 5 inches on the angled rail. Use a combination square to mark the precise locations for drilling, and use an awl to create divots to prevent the drill bit from wandering. Clamp the bottom handrail to the bottom and top posts to keep it stable and plumb while drilling the baluster holes. Use a 13/16-inch self-feeding spade bit to drill holes about 1 1/4 inches deep for the balusters. Install the baluster mounting brackets to the angled ends of the rails using one short screw and one 3-inch screw. Mount the bottom handrail by securing the brackets to the posts with 1 1/2-inch Torx head screws. Insert the aluminum balusters loosely into the pre-drilled holes in the bottom rail. Place the top handrail over the balusters, ensuring each baluster aligns with its corresponding hole. Secure the top handrail to the posts with screws.
