Deltana DDQ56U19 Dutch Door Quadrant Black

Product Description

The DELTANA DDQ56U19 is a Dutch door quadrant designed to align and hold the upper and lower sections of a Dutch door together when both halves need to operate as a single unit. The quadrant mounts at the meeting rail of the door, engaging both leaves so they swing in unison when latched. This hardware is finished in black and is intended for installation by carpenters, finish hardware installers, or door and millwork contractors working on residential or light commercial applications. The unit measures 4.5 inches in length by 4.5 inches in width and weighs approximately 0.7 pounds.

Dutch door quadrants are used wherever a Dutch door installation requires the ability to lock the upper and lower door sections together for full-door operation. This is common in residential entryways, barn-style doors, stable doors, and interior pass-through openings where the split-door function is occasionally bypassed in favor of a single swinging unit. The DDQ56U19 in black finish suits painted or dark-hardware installations and coordinates with other black architectural hardware on the same door set.

Key Features

• Joins upper and lower Dutch door sections for combined single-unit swing operation
• Black finish suited for painted doors and dark architectural hardware schemes
• Compact footprint at 4.5 inches by 4.5 inches for clean meeting-rail installation
• Lightweight at 0.7 pounds for minimal added load on door hardware

Compatibility

Designed as an OEM-style replacement or new-installation Dutch door quadrant for standard residential and light commercial Dutch door assemblies requiring meeting-rail alignment hardware.

Installation Notes

Installation is typically performed by a finish carpenter or licensed door hardware installer. The quadrant should be fitted at the meeting rail with the door sections aligned and plumb before fastening. Use appropriate wood screws or the fasteners specified by the door manufacturer for the substrate material. Verify that both door leaves operate freely and latch correctly before final tightening of all hardware.
