The document discusses different types of brass door handles. It describes brass lever latches, which do not lock but close the door with a latch. Brass lever locks function similarly but can be locked with a key for security. Brass lever bathrooms and privacies can lock bathroom doors from the inside with a snib that also has an emergency release. Brass lever handles on roses attach slightly more difficult than back plates due to screw holes. Brass mortice knobs and rim knobs fit internal doors differently but both use spindles or roses to open and close.
