The going should not be less than 220mm for a private stairway and not less than 240mm for a common stairway. Rise Measured from the top of the tread to top of the tread. Every step or landing must be of equal rise between consecutive floors. The rise of a step must not be more than 220mm for a private stairway and not more than 190mm for a common stairway. Approved Document K Part 1. 14 says the number of risers in a flight should be limited to 16 if a stairway serves an area used for shop or assembly purposes. Part 1. 15 says that stairways of more than 36 risers in consecutive flights should make at least one change of direction of at least 30° between flights. Nosings The nosings on treads usually project 19mm (or thickness of the tread) from the face of the riser below and should, in any case, project not less than 16mm. Pitch The angle between the pitch line and the horizontal should not exceed 42° for a private stairway and 38° for a common stairway. The pitch should not be less than 25° because a stairway built at a shallow angle takes up much more room and is more tiring to ascend. Pitch-line The line drawn from the floor or landing treads in a flight of stairs. Height of Handrails Approved Document K states that flights should have a handrail on at least one side if they are less than 1m wide and on both sides if they are wider than 1m. There is no need for handrails beside the bottom two steps of a stairway. Handrails should be between 840mm and 1000mm high and give firm support. [. . . ] With the router inverted, compress router base until line-up pin projects approx. 19mm (3/4") out, and lock the base in that position. Slide the sub-base onto the end of the pin and screw up lightly the two fixing screws. Ensure the pin rotates freely and tighten the pan head machine screws to secure the subbase to the router base.
