A number of specially shaped curbs for roof-top mounting of equipment are disposed in a nested array which occupies less shipping space than ordinary curbs normally shipped in stacked relationship, one atop the other. Each curb is constructed from four side walls joined at their side edges to produce a box-like structure. The curb has upper and lower rectangular perimeters, the upper perimeter being smaller in each rectangular dimension than the lower perimeter.

[ Having thus described my invention, what is claimed is:] [1.] A nested array of a multitude of curbs bounded by uppermost and lowermost curbs, each of said curbs comprising:a) four side walls joined to form a box-like structure having an interior region, said side walls having interior and exterior surfaces and upper and lower extremities which define upper and lower rectangular perimeters, respectively, disposed in spaced apart parallel relationship, said upper perimeter being smaller in each rectangular dimension than said lower perimeter, said curb having a plane of symmetry that perpendicularly bisects two opposed side walls,b) a crown flange associated with said upper perimeter and adapted to be disposed in a horizontal plane, andc) an outwardly directed base flange associated with said lower perimeter and adapted to rest upon a roof,d) said nested array characterized in that a first curb of said multitude telescopically enters the interior region of a next successive curb to an extent where the base flanges of said curbs are in close parallel adjacency, and the remaining curbs are added in the same telescoping manner.
