A slope block assembly having a bubble level with an eccentrically mounted slope block detachably carried on one end of the level. The slope block has an offset turning axis with a plurality of supporting surfaces, all located at different distances from the turning axis. The support surfaces cooperate with an undersurface or support point on the level to direct a laser beam at a desired angle with respect to a round or flat reference surface. Grooves are provided on the slope block support surfaces as well as on the level undersurface to support the level and slope block assembly on a round or curved reference surface.

1. An adjustable slope leveling device comprising:an elongated level body having opposite ends with a flat undersurface for supporting said level body; a laser beam generator carried on a selected end of said opposite ends for emitting a laser beam parallel with said undersurface; a slope block removably mounted on said selected end of said level body and having an open-ended passageway in coaxial and coextensive alignment with said laser beam; said slope block having at least two parallel spaced-apart flat surfaces in offset relationship with respect to said passageway whereby a selected one of said flat surfaces cooperates with the non-selected end of said level body to support said level body at an angle with regard to a supporting member; an adapter detachably coupling said slope block with said level body; and means carried on said adapter for rotating said slope block thereon whereby a selected one of said flat surfaces is positioned to cooperate with said undersurface and said non-selected end to establish said angle.
