Handrail Brackets Standard
Standard or economy brackets, normally used by builders on entry level homes, have slightly smaller backs and are usually designed to hold 125 pounds per bracket. They are installed the same as above.
A stair rail must be between 34 and 38 inches above the top of the stair tread at all times to meet United States building code requirements. You should check before installing with your local building department for specific rules in your location. Handrails should also extend a foot before and after the stairs, for added safety. This extra extension is not required for private stairways. Stair rails or handrails are required any time stairs raise 30 or more inches above the base level or where there are more than 3 risers. This includes outdoor sections such as decks or porch steps. Residentially in private homes normally only one handrail is required for stairs that are less than 44 inches wide.
In addition to handrail brackets, you may need these items to complete your project: wood handrail material (sourced locally), Wood Glue, 6 to 12 1-1/2 Inch 4D Finishing Nails and two Flat Corner Irons For Returns. Note: Make sure you measure your handrail and the brackets selected before cutting the end miter cuts so the end caps can be used to returns to the wall.
