This set contains all you need for a complete passage function installation (latch secures door, but can be opened from either side by turning knob). For entry functions (exterior doors) also order a dead bolt or furnish your own. For privacy functions (bedroom, bath, etc.) add a privacy latch, or single cylinder dead bolt. See Baldwin hardare for Collegiate Specialties knobs or furnish your own. Because the A&M knob is a large scale oval, a 2-3/4" backset is recommended on new installations.
