On Concrete Slab Style
For on-concrete applications the legs of an inground style stringer are cut to the desired length, next a bolt-on stair kit bracket is screwed to each leg. The stringer legs are then able to be anchor bolted down into place. (A bolt-on stair kit consists of 2 angle brackets and tek screws for fixing to the legs).

How do you calculate the steps you need on your stringer?

Simply measure the height from the top of the landing to the ground directly below, divide this length by 175 rounding to the nearest whole number and deduct 1 for the top landing.

Example: Height = 2415 divided by 175 = 13.8 (14) less 1 = 13 Step.
