WheelRite Tool

It's injection molded gray plastic (about 1/8" thick - kinda like Rubbermaid) with thumb screws. Says "Made in the USA" on it. Semi-"flimsy", though no more than you would expect since it's made of plastic. Plenty stiff enough to do the job it's designed for and rugged enough to stand up to some abuse. Also includes a piece of 14 ga insulated copper wire that you use to simulate the tire profile. There's also an extension piece for measuring ridiculously large wheels. It's a nice tool and should work well. I'll take some pics and post them when I measure for wheels.
