Deltana SDML334U3 Storm Door Latch Square Mortise Lock Bright Brass

SKU CH-CE9K-8D71T

A solid brass storm door latch with a square mortise lock in a bright brass finish

  • Solid brass construction resists corrosion
  • Square mortise lock fits standard storm doors
  • Bright brass finish adds classic appeal
  • Model 334 ensures correct replacement part

Storm Door Latch Square Mortise

The Deltana SDML334U3 is a solid brass storm door latch with a square profile and integrated mortise lock. Its bright brass finish provides a traditional appearance suited to residential entryways. The unit is supplied new and ready for installation on compatible storm doors.

Bright Brass Finish Mortise Lock

This latch replaces worn or missing storm door hardware that uses a square mortise lock configuration. The upgrade is worthwhile when the existing latch body has failed or when a matching bright brass finish is required for consistent door hardware. Buyers needing a different finish, a round latch profile, or a non-mortise locking mechanism should select an alternative model.

Questions about this item

What door thickness does the 334 latch fit?

The 334 mortise lock is designed for standard storm door thicknesses; check your door measurement before ordering.

How is the square mortise lock installed, and what step is often missed?

Mortise a pocket in the door edge, insert the lock body, secure with screws, then fit the square spindle through the latch mechanism — skipping the spindle alignment causes binding.
