Abstract: A device to be used on the legs of standard wooden folding stepladders to insure the stability of said ladders while being used on weak, non-compacted or slippery areas, into which a stepladder might tend to sink, or across which a stepladder might tend to slide.Said device consists of a semi-rigid pad that when attached to the bottom of any or all of the legs of any standard wooden folding stepladder will then increase the stepladder leg footprint area resulting in more stability of said stepladder. In addition, the high friction material of which the stepladder foot pad may be constructed will tend to prevent the stepladder legs from slipping across slippery surfaces.

Abstract: This application discloses a modular stairway system for circular structures or other structures having non-linear walls. The invention comprises a plurality of first stringer means with a plurality of first connecting means integral to said first stringer means for joining the first stringers, a plurality of second stringer means horizontally spaced from and parallel to the first stringer means with a plurality of adjustable second connecting means integral to said second stringer means for adjustably joining the second stringers such that the first and second stringers conform to the curvature of the structure. A plurality of stairs are horizontally interposed between the first and second stringers, and a stair mounting means for securing the stairs to the first and second stringers are provided.
