Abstract

An extendable/retractable ladder assembly includes a first column and a second column, the first column nesting in the second column, and a first rung coupled to, and extending from the second column. A ladder assembly bracket includes a collar portion, which extends about the second column, and a rung portion, which extends from the collar portion into the first rung. The collar portion may be gripped by a hand of an operator in order to position a thumb of the hand in engagement with a button to retract a locking pin of a latch assembly mounted within the rung portion of the bracket.
