ABSTRACT:
There is disclosed a device for securing refractory and/or insulating material against a furnace wall. The device comprises a metal pin or stud which is attached to the wall at one end and is provided with a plurality of notched portions adjacent the other end. The stud cooperates with a hollow, preferably ceramic anchor, which is provided with a rectangular slot that fits over the notched portion of the stud and may be secured thereon by rotating an anchor through 90 degrees to effect a locking arrangement. The anchors may be interfitted in order to provide a support for electrical heating elements. The significant feature is that the size of the anchor is such as to allow another anchor to interlock and make a collar which can support electrical heating elements. As the anchor is preferably a ceramic support it is electrically insulating, and prevents the electrical heating elements from contacting the studs.
