An improved kiln or oven useable support structure is provided which includes a base having a surface with a plurality of vertically oriented support bores disposed thereacross. A plurality of straight and crank shaped support pins having predetermined cross-sections are removably insertable into the bores of said base. A curved support member has in one end an aperture having a configuration minimally larger than the cross-section of said support pins. When said aperture encircles a support pin and the axis of said aperture is substantially parallel with said pin the two move freely with respect to one another, but when the axis of said aperture is not substantially parallel with said pin, the two pinch-lock or bind to maintain their relative positions.
