Mm Manufacturing 601-12X12X10 Register Box 12x12x10 in

Product Description

The MM Manufacturing 601-12X12X10 is a 601 series register box with a snap-rail flange, designed for use in residential and light commercial forced-air HVAC distribution systems. This box provides a transition point between round supply duct and a ceiling or floor register opening. The snap-rail flange allows registers to seat and lock securely without additional fasteners. At 2.4 pounds, it is lightweight enough for single-technician overhead installation. The 12 x 12 x 10 inch nominal size fits standard register openings in typical residential duct layouts.

This register box is used where a round duct run terminates at a wall, ceiling, or floor diffuser location. It accepts round duct from 4 inches through 9 inches in diameter and is available in nine nominal sizes to match a range of supply layouts. HVAC installers and sheet metal contractors use this box during new construction and retrofit duct work where a clean, flanged register termination is required.

Installation Notes

Installation is typically performed by a licensed HVAC technician or sheet metal contractor. Shut down the air handling system before attaching or modifying duct connections.
