Deltana DDQ56U3 Dutch Door Quadrant Bright Brass

Product Description

The DELTANA DDQ56U3 is a Dutch door quadrant designed to align and hold the upper and lower sections of a Dutch door in a fixed, latched position. When engaged, the quadrant prevents independent movement of the door halves, creating a solid unified door panel. This hardware is fabricated for use in residential and light commercial door applications where Dutch door configurations are specified. Installation is handled by carpenters, finish hardware installers, and general contractors during door hardware trim-out. The bright brass finish provides a traditional appearance suited to period and transitional architectural styles.

Dutch door quadrants are used wherever a split door must be secured as a single unit — most commonly in residential entry doors, stable doors, half-door pass-through applications, and interior Dutch doors. This quadrant mounts to the meeting rail of the door stiles and keeps the bolt engaged until manually released. The DDQ56U3 is sold as a single unit and is appropriate for new construction and replacement applications alike.

Installation Notes

Installation is performed by a finish carpenter or door hardware installer using standard hand tools. The quadrant mounts to the edge or face of the door stile at the meeting rail — confirm door prep dimensions before ordering. Ensure both door sections are properly aligned before marking and drilling fastener locations. Remove any existing hardware and fully test door swing and alignment before final fastener torque.
