Instructions

1

Determine the points that will support the handrail. Handrail height is between 34 and 38 inches above the floor or stairs. The handrail hardware attaches directly to the wall if the stairs or walkway is located next to the wall. If the walkway is away from the building install posts, usually 4-by-4 inch 6-foot long treated posts, every 6 feet along the walkway.
2

Dig the post holes using a post hole auger to a depth of about 2 feet. Set the posts in the holes and brace them in a vertically straight position. Fill the hole around the post with the soil removed when you dug the hole and pack in place.
3

Attach the handrail support hardware to the wall or posts. The hardware should set the handrail at least 1 1/2 inches from the wall to allow room to grasp the rail.
4

Attach the handrail to the support hardware. The handrail material should fit the hand and be easy to grasp in the event of a fall. Round rails of 1 1/4 inch to 2 inches in diameter are recommended, according to the website Inspectapedia. An oblong shaped railing should be no wider than 2 1/4 inches. The handrail should form one continuous support surface throughout the walkway or stairway. Once grasped by the person he should be able to slide his hand along the handrail to the end of the stairs or walkway.
