ABSTRACT:
This invention relates to an extendable level which, by means of two slidable extension members on a central body, can more than double its collapsible length. The invention comprises a device which can lock the level in any length from fully collapsed to fully extended. An attachment is provided which can convert the invented level into a large carpenter's square. Further, the extension level, with a scale on its top edge, can measure inside lengths between opposing wall surfaces.
