Sub-Zero Classic Series (BI) Dual Installation Filler Strip
Topics:
- Is a filler strip required to install two Classic (BI) units against one another?
- Can two side-by-side BI units be installed together?
- Can two units with the same door swing be installed next to one another?
- Can the hinge side of one unit be installed next to the handle of another in a dual installation?
Answer:
Two Classic series (BI) units, single door or over-under, with opposite door swings can be installed next to one another without a filler strip.
- In this application, a dual installation accessory kit is required.
- Contact a Local Dealer for further sales information.
Two Classic units in any of the following combinations require a minimum 2" filler strip between them:
- Two single door BI Series units with the same door swing
- Two individual side-by-side units
- Two individual French door units
- A side-by-side unit next to a single door unit
- A French door unit next to a single door unit
The filler strip is required to prevent condensation between the units and it runs the height of the unit.
- Each unit requires its own opening.
- The minimum 2" filler is the space between the two openings.
- Failure to use a filler strip will result in the door being unable to fully open and likely cause damage to both units.
