Spacer for a vertical support structure of a heating element coil includes a mating feature including complimentary components on first opposing sides of the spacer, a cavity, open to second opposing sides of the spacer, and an extension, offset from an axis intersecting the mating features, the extension including a pocket sized to fit an individual loop of the heating element coil. The spacer can be incorporated into a support structure for a heating element coil interlocking adjacent loops of the coil so that they are retained in a collinear and concentric arrangement while allowing the loops of the coil to move freely inward and outward from the central axis in unison. |
