Product Description
Stainless Steel Ceiling Air Box: Rugged Register Coverage Built to Last. Made in the USA by AMERICAN TRUCKBOXES ATB®️
This 18 gauge stainless steel ceiling air box is built for contractors, HVAC installers, and facility maintenance crews who need a register enclosure that resists corrosion in humid or washdown environments. A round pipe or collar connection ties directly into your ductwork, and the heavy stainless construction stands up to daily wear on a job site or in a commercial kitchen. Every box is manufactured by American Truckboxes LLC in Blanchard, North Dakota, with custom sizing and facility-wide orders available.
Key Features
- Corrosion resistance that outlasts painted steel: 18 gauge stainless steel holds up in humid and washdown environments where painted boxes rust through
- Direct ductwork tie-in: round pipe or collar connection mates cleanly to standard HVAC ducting
- Eight connection sizes on one listing: choose from 6 inch up to 20 inch connection diameters to cover small utility runs and large supply trunks
- Consistent OD-to-connection ratio: outer dimensions step up proportionally, from 7 inch square on the 6 inch connection to 21 inch square on the 20 inch connection
- No paint to chip or touch up: stainless finish means no repainting after scratches from ladders or tools during installation
- Register-ready sizing: outer dimensions match standard ceiling register openings for a clean, flush-mount look
- Fast turnaround: stocked sizes ship in 2-3 business days so multi-unit jobs do not stall
