A stair assembly includes at least one joist comprising an upper wall, a first lateral wall extending from the upper wall, and a second lateral wall extending from the upper wall. At least one stair step support bracket includes a tray support wall, a first side wall extending from the tray support wall, and a second side wall extending from the tray support wall. The first and second side walls define a pair of first front aligned positioning holes configured to receive a first set pin and a pair of first rear aligned positioning holes configured to receive a second set pin. The pairs of first front and rear aligned positioning holes disposed such that when the first and second set pins received therethrough contact the upper wall of the at least one joist, the tray support wall is positioned at a first rise dimension.

Systems and methods of covering structural bases are described herein. The systems include a plurality of floating field tiles arranged to cover a top surface of the structural base, a mat positioned between a bottom surface of at least one of the floating field tiles and a top surface of the structural base and a coping system secured to the top surface of the structural base. The coping system has an upper edge that is level with or below a top surface of the floating field tiles and forms a fixed perimeter around the plurality of floating field tiles to inhibit lateral movement of the plurality of floating field tiles.

A ceiling ladder having a plurality of sections that can be climbed by a user when in an unfolded position into an attic and that can be folded together into a retracted position to be stored above the ceiling. The ladder has a deep step, which has a width greater than the width of other steps of the ladder, in which is located between about 2-5 feet from the floor when the ladder is in the unfolded position so user can stand on the deep step in place objects into the attic without having to climb into the attic. A deep step for a ceiling ladder.

A bilateral bracket for steps to be fixed on a stringer having a number of steps and risers, the bilateral bracket having a generally flat body defining a framing edge having a riser edge and a tread edge; the riser edge having a riser flange perpendicularly extending therefrom in a first direction; the tread edge having a tread flange perpendicularly extending therefrom in the first direction, wherein the tread extends between a distal end and a proximal end; the framing edge defining an acute angle relative to each other, wherein the flat body does not project beyond a profile defined by the distal and proximal ends inward of a profile defined by the framing edge; and a stringer edge along the body, opposite the framing edge, wherein the stringer edge has an array of holes for selectively attaching to either side of the stringer.

Coping and skirting systems for structural bases are described herein. The coping and skirting systems include at least one coping tile and a support structure configured to be mounted on a front surface of the structural base and to support the at least one coping tile on the structural base. The support structure is also configured to be mounted on the structural base at a selectable position that provides for a top surface of the coping tile to be level with a top surface of a field tile on the structural base.

A device for making a molded stair tread is described. The device can have: a base; a pivoting assembly; a molding template connected to the pivoting assembly; a holding device connected to the molding template, the holding device having a clamp jaw and a pivot configured to rotate the holding device relative to the molding template; and a locking mechanism configured to hold the molding template and the holding device in an open configuration such that the holding device can accept a first part of the plastic sheet and configured to release the molding template and the holding device such that the holding device is in a securing configuration that secures, via the clamp jaw, the first part of the plastic sheet to the first side of the molding template at the first longitudinal edge of the molding template. Methods for making the stair tread are described as well as the molded stair tread.

A stair tread cover suitable for covering at least one step in a staircase. The stair tread cover includes at least a front portion and a back portion. The front and back portion each have a top surface and a bottom surface. At least one adhesive or tacky region is optionally positioned on the bottom surface of the front portion of the stair tread cover, and at least one gripping region is optionally positioned on the top surface of the front portion of the stair tread cover.
