ABSTRACT:
A portable, adjustable work trestle for use in the construction trades. The trestle is light weight and collapsible. The trestle comprises a foldable base structure with an elongated ladder-type configuration. The base structure has a predetermined height and includes four legs connected via step pads, board locks, board braces, and folding locks. A work surface board is disposed at the top or apex area of the trestle between the board locks. Four leg extensions are cooperatively and extensibly adjustably connected to the legs. The leg extensions enable the user to level and/or increase the height of the base structure. Optional second leg extensions may be added to further increase the height of the work surface provided by the trestle.
