An adjustable platform extension bracket for work platform systems comprises a post member having two posts joined by a plurality of positional structures. A first connection portion forms a first channel such that the first connection portion is symmetrical along an axis parallel with and passing through the channel. The post member is slidingly engaged in the first channel such that at least one of the positional structures is positionable in the channel. The bracket does not require any diagonal support. The dimensions of work platforms, particularly suspended work platform systems, may be extended using the adjustable platform extension bracket.
