I was thinking of lowering the railing on some porch railing that I put up because there is too much gap between bottom of railing and the edge of the steps. If I do so, will it affect the length of railing horizontally?(i.e. Will I need to shorten it?)
Length??? I don't understand what that means by lowering the "porch railing". However, If the porch is 30" or more above the adjacent grade, the guardrail must be 42" high. (See IBC Section 1013.2.)
noybman's reply helped me the most.
I have lowered the railing on one side of the the porch step railings today. What I mean is that the railing is not attached to the top and bottom post as high as it was. I didn't have to shorten the length of the railing. I shortened the posts (from the bottom) about 7 inches on the top and bottom porch steps posts. This reduced greatly the distance from the corner of the steps to the bottom of the railing. Shortening the posts reduce the distance from the top of the railing to the top of the post to around 1 inch. I will post late tomorrow pictures of the railing at a higher (one I haven't fixed yet) and the shorter heights.
