A leveling assembly to establish elevations in a building structure for installing cabinets, bookshelves, countertops, etc. There is a telescoping mounting post adapted to be positioned in bearing engagement between a floor surface and the top of a doorway, ceiling or other upper surface. A laser that transmits a horizontal laser beam is mounted to a mounting device that can be moved to different positions along the length of the post. Locking devices hold the laser-mounting device in place, and also properly position the post to be in firm engagement with its bearing surfaces. The laser-mounting device can be swung to upper and lower positions. |
