Patent ID: 6842992

Claim:
A building-wall-layout tool comprising: at least one line holder which includes a fastener section and a handle section which are separated predeterminedly intermediate proximate a first side and a second side of the line holder; the fastener section having a fastener slot extended from proximate a first side to proximate a second side of the fastener section; the fastener slot being articulated for receiving at least two line fasteners predeterminedly for being slid in the fastener slot and affixed removably to edges of the fastener slot selectively intermediate the first side and the second side of the fastener section; the fastener slot having a length predeterminedly longer than a width of intended walls for receiving a first line fastener proximate a first side of a thickness range of the intended walls and for receiving a second line fastener proximate a second side of the thickness range of the intended walls; the first side of the line holder includes a first spike aperture that is articulated for receiving a first spike leg predeterminedly in a vertical orientation; the second side of the line holder including a second spike aperture that is articulated for receiving a second spike leg predeterminedly in a vertical orientation; and the handle section being articulated for hand-carrying the line holder, for accurately and conveniently positioning the line holder proximate the intended walls and any intended conduits, for positioning the first spike leg and the second spike leg in ground material proximate edges of an intended concrete slab and for removing the line holder from the ground material selectively without undesired contact with any line fasteners in the fastener slot and without undesired contact with the fastener section.
