Claim:
An adjustable mold for making drainage channel sections of various sizes, shapes, or slopes, the adjustable mold comprising: an interior mold portion, said interior mold defining a base; a base support that interfaces with said base of said interior mold portion; and an exterior mold portion at least partially surrounding said interior mold portion to thereby define a mold, said exterior mold portion comprising: first and second opposing sidewalls comprising a distal end and a proximal end, wherein the adjustable mold is structured so that at least said first sidewall is positionable at various distances apart from said second sidewall in order to change the overall width of the drainage channel, wherein the first sidewall is coupled to a first portion of the base support, wherein the second sidewall is coupled to a second portion of the base support, and wherein the base support is structured such that the first portion of the base support can move relative to the second portion of the base support to allow the first sidewall to be moved towards or away from the second sidewall; first and second opposing endwalls, wherein said first endwall is located at the proximal end of said first and second opposing sidewalls and said second endwall is located at the distal end of said first and second opposing sidewalls; at least one mold spacer located between said interior mold and at least one of said first and second opposing sidewalls of said exterior mold, said mold spacer defining first and second ends; and at least one positioning mechanism structured to allow at least one of said first and second ends of said mold spacer to be positioned at different heights along said at least one of said first and second opposing sidewalls of said exterior mold, wherein said at least one positioning mechanism comprises at least two elongate members extending between said base support and said mold spacer, each of said at least two elongate members being structured such that the length of each elongate member extending between said base support and said mold spacer is adjustable, wherein at least one of said base support and said mold spacer defines an aperture that is structured to threadably receive an end of at least one of said at least two elongate members.
