6″ x 6″ Transition Box 

6″ x 6″ Transition Box delivers reliable performance in the smallest footprint possible. Designed for compact applications in marine vessels, RVs, and other confined spaces, this ultra-compact transition box ensures efficient airflow routing without sacrificing performance.

Whether you’re cooling a small cabin, berth, head, or storage area, the 6″ x 6″ Transition Box provides a clean, effective connection between your flexible ducting and the interior grille. Its compact size makes it ideal for installations with limited clearance—perfect for ceiling drops, wall recesses, or cabinetry where larger boxes simply won’t fit.

This transition box is engineered to work seamlessly with MSI grilles and ducting, creating a smooth transition from the duct to the room’s air outlet. Its tight-sealing design helps maintain system pressure and prevent leaks, ensuring that chilled air reaches the space exactly where you want it.

Whatever your choice, wood-framed or plastic-framed grilles, you will require a way to effectively duct the chilled air to them. We offer a wide selection of plastic ducting products—from the hose adapter on the air handler to the transitions behind the grilles. The 6″ x 6″ Transition Box is the smallest standard offering in this lineup, and it plays a critical role in ensuring optimal performance in compact applications.

Crafted from lightweight, durable materials, this transition box is built to handle the rigors of marine and mobile environments. It resists corrosion, moisture, and vibration—key considerations for HVAC systems exposed to ever-changing conditions. Its simple design allows for quick and secure installation, even in difficult-to-access areas.
