Note : the 539/549 Fronts require a 540 WDK Wire Dress Guard with the 922 heater.
Cast Iron Tolerances – Due to the nature of Cast Iron, dimensional consistency may vary from one unit to the next and
some variation in surface finish and flatness is to be expected. We have done our best to control and make allowance,
however some variation is inevitable.
Closure plates may be required for insert applications where cast fronts do not cover entire openings.
Standard black 33" high x 36" wide closure plate with black aluminum extrusion edge is available.
