The stainless steel profile mounting plate bracket, illustrated in the sketches below, is used to support plates for this purpose. The plate used to close off a portion of the opening will need to be sized for each individual application. 1) Dia. = 1/4" 2) Profile plate mounting bracket 3) Profile plate www. maxoncorp. com combustion systems for industry Maxon reserves the right to alter specifications and data without prior notice.
