A brace locking mechanism locks the foldable braces of a folding ladder in the open position. The brace locking mechanism is used with a ladder that has a stepped unit and a support unit foldably attached to the stepped unit with a foldable brace extending between the stepped unit and the support unit. The brace locking mechanism comprises a lock block that is movable between a locked position in which the lock block prevents the foldable braces from moving out of their open position when the ladder is open, and an unlocked position in which the ladder may be folded into the storage position.

A folding leg for a stepladder is disclosed. The folding leg allows the width of the stepladder base to be narrowed when in the stored orientation and widened while in an in-use orientation.

The present invention discloses a rooftop fall protection system including a plurality of mast assemblies and at least one ladder assembly removably engaged with the mast assembly. The ladder facilitates the elevation of a human to an elevated surface on a structure. Each of the ladder assemblies and mast assemblies are coupled to at least one cross-member positioned at a height above the perimeter of the elevated surface. The cross-member protects the human from falling from the elevated surface of the structure.

An adjustable ladder and stair system has a folding stair assembly including a ladder-member having a first-end, a second-end, a plurality of rungs equidistantly spaced between a first-rail and a second-rail, and a securer, a stair-member having a stair-portion, a first-rail-slide-mechanism, a second-rail-slide-mechanism, a first-rail-locking-mechanism, and a second-rail-locking-mechanism. The ladder-member may be secured in a vertical position parallel to a substantially vertical item desired to be ascended via the securer. The stair-member is adjustable to accommodate a desired angle. The folding stair assembly provides an apparatus for safely accessing a substantially vertical item desired to be ascended such as a roll off garbage bins.

A tree stick mount attachment assembly includes a tree stick body. A panel has a front side, a back side, and a perimeter edge extending between the front and back sides. The backs side faces and is attached to the tree stick body. The perimeter edge has a plurality of slots therein and each of the slots extends through the front and back sides. The slots removably receive a tether extending around the tree to retain the tree stick body on the tree. The tether is attached to the tree stick body and extended around the tree. Thereafter, the tether is then extended into the slots to secure the tree stick body to the tree.

Apparatuses and systems are disclosed for portable stairs. In one embodiment, a support structure extends from a lower level to an upper level. In a certain embodiment, a plurality of steps are coupled to the support structure. In a further embodiment, an apparatus includes means for independent, per-step adjustment of step positions relative to the support structure.
