Do It Right Before The Wall Closes
Set up your mini split connections the clean way from the start—so you’re not fixing it later.

The RoughinBox Multi-Drain Rough-In Box is designed to simplify wall-mounted mini split installations in new construction and open-wall remodel applications. It helps protect the lineset, wiring, and drain outlet during rough-in and sheetrock stages, making final installation cleaner and easier.

This rough-in box is built for wood or metal studs at 16-inch centers and fits standard wall cavities with a compact profile. Its updated design includes an extra bottom lineset port and supports both vertical and horizontal condensate discharge, making it a strong fit for standard high-wall installations as well as tighter spaces such as applications above doors or windows.

Additional features include a one-piece waterproof molded construction, reversible left- or right-hand installation, direct evaporator drain hose connection with supplied adaptor, and a hinged faceplate for easier access and protection during rough-in. It can also accommodate a concealed reservoir and/or condensate pump when needed.


Simplify Rough-In Installation and Protect Critical Components

Prepping a mini split installation is faster, cleaner, and more organized with a multi-position rough-in box. Designed to protect line sets, wiring, and drain connections during construction, it helps prevent damage from other trades and ensures everything is properly positioned before final installation.

With multi-drain flexibility and stud-mounted installation, this rough-in box adapts easily to different layouts while keeping your install consistent and professional. The result is a smoother final install, reduced callbacks, and a cleaner finish once the indoor unit is mounted. It also helps streamline installation for technicians by keeping all connections centralized and easy to access.

For applications requiring rear wall access, an optional rear cover plate is available and can be easily installed or removed with screws. This allows for convenient access to connections when needed while maintaining a clean, finished appearance once installation is complete.
