Sub-Zero Triple Installation


  • Can Sub-Zero units be installed 3 in a row?
  • Are there specifications for a triple installation of Sub-Zero units?
  • Is a heater kit or dual installation kit needed for triple installation?


Any number of multiple Sub-Zero units can be installed together in combination or in a row. Keep the following in mind:

  • A heater is needed between each pair of units if they are less than 2" apart.
  • For hinge to hinge installations, use 90° door stops to prevent cabinet damage.
  • Add the individual unit widths together for the overall opening width.
  • Classic (Formerly Built-In) Series units cannot be installed right next to each other in a triple installation. A 2" filler would be necessary to prevent door interference.
  • See also, Sub-Zero Dual Installation Kit Information.

Refer to the Sub-Zero Design Guide for design specifications.
