Entry
lock: (Front & Back) Entry locksets
have push or push and turn button locking from the
inside and key unlocking from the outside. Pushing
or turning the button locks the outside knob or
lever. A key is needed to enter from the outside
unless the interior button is manually unlocked.
The push or turn button locks the outside until
the inside button is moved again.
Vestibule
lock: Vestibule locksets are always locked
from the outside, and are unlocked with a key from
the outside. The inside is always unlocked.
Storeroom
lock: Storeroom locksets are always locked
from the outside, so always need a key in the exterior
knob or lever lock to unlock from the outside. The
inside lever is always unlocked.
Classroom
lock: Classroom locksets always have the
inside knob or lever unlocked. The outside knob
or lever is locked and unlocked by key.
Bathroom
and bedroom privacy lock: (Bed & Bath)
Privacy locksets are locked with an inside push-button.
Turning the inside knob or lever releases the lock.
A small screwdriver can be used as an emergency
key, from the outside, if necessary.
Passage
set: (Closet & Hall) Passage locksets
keep doors firmly closed, but do not actually lock.
Both knobs always turn free.
Cylindrical
and Tubular Locksets and Leversets
Cylindrical and tubular locksets differ in several ways, the
most important of which, to many purchasers, is price: tubular
locksets are less costly. Not long ago, tubular locksets were
also easier to install, but today’s standardized door
preparation, using templates, means both styles are about equally
easy to add to any ordinary door.
Locksets made in a drum style are cylindrical and tend to be
less restrictive when operated from the inside—that is,
the cylindrical lockset allows for one step egress.
Tubular locksets are easily identified by their three prongs,
consisting of two posts and a spindle.
S. Parker locksets are available in grades 1, 2 and 3. The significant
differences are manufacturing of a quality to withstand increased
use and fire ratings, with the more durable being grades 1 and
2: grade 3 is designed to last a long time under standard use
in residences, while grades 1 and 2 are for heavier commercial
and residential use.

Non-Handed
vs. Handed
All S.Parker Grade 1 and 2 cylindrical lever, and all
knob locksets are non-handed. They can be used on right
or left hand opening doors. Most Grade 3 locks are also
non-handed. There are a few decorator levers that are
specific to right or left hand door openings. They are
noted appropriately.
