MarketAir RoughIn Box with Cover Plate for New Construction Wall-Mounted Mini Split Systems

Do It Right Before The Wall Closes
Set up your mini split connections the clean way from the start—then finish it off with a clean, polished look.

This RoughinBox kit includes both the rough-in box and matching cover plate, giving you a complete solution for organizing and finishing your mini split installation. Instead of leaving lines, wiring, and drain connections exposed or loosely routed inside the wall, this system creates a dedicated space to keep everything protected and in place from the beginning.

During rough-in, the box helps organize and protect the lineset, wiring, and drain connections before drywall goes up. It supports both vertical and horizontal condensate drain configurations and fits standard 16-inch stud bays, making it ideal for new construction and open-wall remodel projects.

Once the installation is complete, the included cover plate hides the wall access opening behind the indoor unit, giving your install a cleaner, more finished appearance. It’s a simple way to avoid exposed cutouts and create a more professional look without extra effort.

With a durable, waterproof molded design, reversible installation options, and support for condensate pumps when needed, this kit helps you plan ahead, protect your install, and finish the job the right way.
