This non-insulated wall case is molded from fiberglass-reinforced polyester compound. This SMC (Sheet-Molded Compound) wall case offers outstanding strength, durability, color retention, water integrity and corrosion resistance. The dimensions of the RAB77 wall case are 42-1/8" wide by 16-1/4" high by 13-7/8" deep. 

  • Both wall cases are of universal design, accepting all Zoneline chassis of current design as well as all GE Zoneline chassis produced since 1961.
  • Drain holes are provided in the rear of the wall case to permit excessive cooling condensate water, heat pump condensate or precipitation entering the wall case to drain freely. A drain kit may be connected to the wall case to control any water draining from the wall case.
  • Requires a wall opening of 16 1/2" H x 42 3/8" W.
