Patent attributes
An adjustable height rebar chair includes a threaded rebar support column threadably connected to a tripod base, and each consists of a respective one-piece body of molded plastic. A top end of the rebar support column terminates in an adjustment handle that defines first and second concave rebar cradles that are orthogonal to each other. The rebar support column also includes a vertical surface extending from the adjustment handle toward a bottom end of a threaded rod, and the vertical surface has numerical indicia that decrease in magnitude in a direction toward the adjustment handle. A number of the numerical indicia that is located next to a top of the central core corresponds to a distance along a vertical centerline from the three feet of the tripod base to at least one of the first and second concave rebar cradles.
