(10) Element Sizes 3/6, 4/9, and 6/12: Held in place by a hex nut and slotted head machine screw, the plate holder consists of two ceramic plates, two pieces of ceramic fiber paper
and a piece of high-temperature ceramic fiberboard. This fiberboard, referred to as a tab, is located between the ceramic plates. The length of the tab varies depending on the thickness of the furnace roof.
The insulating tab fills the opening from the top of the ceramic plates to the hot face of the furnace chamber. The tab seals and reduces the heat losses between the two element legs.
The main advantage of the plate holder is that the Moly-D elements can be installed from the outside of the furnace.

The binding post to Moly-D (K type strap) is offered for the 4/9, 6/12, 9/18 and 12/24 elements. There are two styles available for the 3/6 element; E-type for connecting binding post to Moly-D, and F-type for connecting Moly-D to Moly-D.
