The Deltana SDML334 is a solid brass mortise latchset for wood screen and storm doors. It has rectangular escutcheon plates, an exterior knob, an interior lever, and a mortise lock body installed in the edge of the door.
Will this fit my door?
If your existing lock has the same rectangular plate layout and mortise pocket, and the measurements below match, the SDML334 will most likely fit. A mortise pocket must be cut into the door edge; this is not a tubular-latch replacement.
Installation skill required
This mortise lock requires accurate drilling and cutting a pocket into the door edge. Installation should be performed by someone with competent woodworking or carpentry skills. Compare the dimension drawing and installation diagram with the door before cutting.
