A pool ladder may have a first and second leg extension, each having a generally continuous profile; a first tread may comprise first and second through-holes, the first through-hole being sized to slidingly receive the generally continuous profile of the first leg extension, and the second through-hole being sized to slidingly receive the generally continuous profile of the second leg extension; and a first and second tread support. The first tread support may be engaged at a tread location on the first leg extension and may be separate from the first leg extension. The second tread support may be engaged at a tread location on the second leg extension and may be separate from the second leg extension. Each of the first and second tread supports may protrude from the respective leg extension a sufficient amount to prevent the first and second through-holes from sliding past the tread locations.

An extendable/retractable ladder assembly includes a first stile and a second stile and a plurality of rungs extending therebetween. Each stile may comprise a plurality of columns disposed in a nested arrangement for relative axial movement in a telescopic fashion. A connector assembly connects the rungs to respective columns in the first and second stiles. The ladder has improved manufacturability since connector assemblies may be assembled before connecting the rungs to respective columns. The standing surface of the rungs may be angled such that it is rotated towards horizontal when the ladder assembly is leaned against a wall. A latch assembly may be used to selectively lock relative axial movement between adjacent columns. The latch assembly includes a locking pin assembly comprised of a central post and an outer metal sleeve. An air damper may also be used to control airflow through the columns.

A ladder with a powered lifting platform includes a first frame member and a second frame member each having a pair of support legs and an upper crossbar, wherein the first frame member is pivotally connected to the second frame member. Multiple steps are affixed between the pair of support legs of the first frame member. A lifting platform is slidably mounted between the pair of support legs of the second frame member. A powered lift mechanism has a control unit which includes a first control button configured to activate the powered lift mechanism and raise the lifting platform toward the upper crossbars and a second control button configured to activate the powered lift mechanism and lower the lifting platform away from the upper crossbars. The device allows users to safely transport heavier items to the top of the ladder without requiring the user to carry the item.

A cargo trailer ladder assembly for safely entering or exiting a cargo trailer includes a pair of load locks that is each extendable between walls of a cargo trailer for securing cargo in the cargo trailer. A ladder is included that has a plurality of engagement points thereon. Each of the load locks is positionable in respective ones of the engagement points for storing the load locks with the ladder. The ladder is positionable to engage the cargo trailer to facilitate a user to safely climb into or out of the cargo trailer. A strap is removably coupled to the ladder and the strap can be slung over the user's shoulder for carrying the ladder.
