Abstract
A heater rack assembly, of the type which supports an electric heating coil in a pattern of parallel rows in a plane, utilizes double-ended stand-off insulators which are formed wafer-like in the plane. The insulators have, at each end, pairs of hook portions facing each other to provide a throat, which opens into a wire-accommodating slot behind the hook tips, the slot converging toward the center at an angle of 150.degree. or less. Adjacent turns of the coil are to be accommodated within the slot. Its convergence retains within the slot adjacent coil turns which might otherwise escape, requiring for such escape what is in effect a reverse in-plane twisting displacement.
