Deltana SDML334U19 Storm Door Mortise Latch Black

Product Description

The DELTANA SDML334U19 is a square-style mortise latch designed for storm door applications. It provides reliable latching action through a mortise-style mechanism and ships in a black finish that suits both traditional and contemporary door hardware installations. Licensed door and hardware installers, carpenters, and general contractors typically handle this type of hardware as part of a storm door rough-in or replacement project. The black finish offers a clean, consistent look on painted or dark-toned door frames. At 1.6 pounds, the unit is compact and straightforward to handle during installation.

This mortise latch is suited for residential and light commercial storm door installations where a square-corner, mortise-style latch set is specified. It is sold individually and is appropriate for new construction as well as retrofit applications where an existing storm door latch requires replacement. The square profile aligns with standard mortise pockets on storm door stiles.

Installation Notes

Installation is typically performed by a licensed carpenter, door hardware specialist, or general contractor. Before beginning, ensure the door panel is fully supported and that any attached storm door hardware is disengaged. A chisel and mallet may be required to square the mortise pocket to match the latch body dimensions. Follow local building codes and the door manufacturer's instructions for proper latch alignment and fastener torque.
