Support is provided by assemblies having spaced apart mounting assemblies with a rigid bridge compliantly mounted therebetween. The heater strip is compliantly connected to the bridge. Each mounting assembly has a metal post connected to the furnace heating chamber and surrounded by a ceramic sleeve. The ceramic sleeve is surrounded by two ceramic tubes which hold an end of the bridge therebetween.
