Stair Rail Unique Brackets
Measuring from the completed stair rail brackets or an adjacent ramp slope, the height of stair joints should be 34-36 inches, according to IRC. The rails as a transition between flights go from the rails to the guard rails (egg on a landing) or start a flight may exceed this mandate. A whistleblowing, also known as a snake or boot support, that goes over the minimum tread can be lower than these requirements. At least one handrail is required on one side of a continuous staircase if it has four or more steps.
