DOOR HARDWARE - Conversion vs. Mortise Door Sets
Question: How do I know if I need a conversion door set or a mortise lock set?
Answer: If you have new doors that are pre-drilled, you can use one of our conversion door sets to get antique style hardware with an apparatus that fits your door. If you have existing hardware on your doors you will need to determine if you have mortise locks or tubular latches. A conversion door set is for modern doors that use a tubular latch as opposed to a mortise lock. Refer to the definitions of mortise lock and tubular latch in the glossary.
