The DELTANA SDML334U26 is a square-style mortise latch designed for storm door applications. It features a bright chrome finish and is built for use in residential door hardware installations. The mortise-style mechanism fits into a routed pocket in the door edge, providing a clean and secure latch engagement. At 1.6 pounds, the unit is solid enough for frequent-use storm door cycles. Licensed contractors and experienced installers handle this type of hardware during door pre-hang or retrofit projects where a polished, corrosion-resistant finish is specified.
This mortise latch is suited for residential storm doors where a square-profile trim style is required. The bright chrome finish coordinates with standard chrome door hardware sets. It is sold individually and is appropriate for new construction or replacement installations on hinged storm door assemblies where a mortise-style latch mechanism is specified by the project or building owner.
Designed as an OEM-style replacement or new-installation mortise latch for residential storm doors requiring a square-trim mortise mechanism in a bright chrome finish.
Installation is typically performed by a licensed carpenter or door hardware installer. Power down any electronic door accessories and ensure the door is secured or removed from its hinges before beginning mortise work. A mortise chisel and router are standard tools for cutting the door edge pocket to the required dimensions. Follow local building codes for door hardware requirements on storm and entry door assemblies.
