That is exactly what it is cut for. The Baldwin 6318 lock body has a 2-1/2 inch backset, so the cross bore for the knob or lever spindle sits 2-1/2 inches back from the door edge. If your existing mortise pocket and trim holes are laid out for a 2-3/8 or 2-3/4 inch backset, the trim will not line up and you would need a body matched to that backset instead.

It is handed, and the L designates a left hand body. Handing is fixed on this one, so a right hand opening needs the right hand version rather than a field reversal. Determine hand from the outside of the door: if the hinges are on your left and the door swings away from you, that is left hand.

The latch faceplate measures 1-1/4 x 8 inches, so the door edge has to be routed for that plate and the pocket sized to accept the body behind it. It suits doors 1-3/8 inches thick and over.

Passage function, which means it latches the door and both sides always retract the latch. No key, no privacy turn. Use it on halls, closets and pantry doors. For a bath or bedroom that needs to lock from inside, choose a privacy function mortise body instead, such as the Cal-Royal NM8440 privacy/bed/bath mortise lockset or the Hager 3840S.

No. This is the mortise lock body only, the case that goes in the door edge. Knobs or levers, rosettes or escutcheons, spindles and the cylinder-side trim are ordered separately from the matching Estate Series trim so the finish and backset agree.

The Baldwin 6318 is a residential Estate Series passage mortise lock body with a 2-1/2 inch backset. For a commercial opening carrying heavy traffic, the Falcon MA101 is a Grade 1 heavy-duty mortise passage lock with field reversible operation and a fire rating, and the Schlage PM010 is a Grade 1 passage latch mortise lock for 1-3/4 inch doors. Both are keyed-function-free passage devices like the 6318, but built to Grade 1 commercial criteria.

If the other doors already run Baldwin Estate Series mortise hardware at a 2-1/2 inch backset with an ASA strike and a 1-1/4 x 8 inch faceplate cutout, the 6318 drops into the same prep. Order the left hand body for left hand doors and the right hand version elsewhere, since handing is not reversible.

They serve a different purpose. The Baldwin 6318 is passage only, with no cylinder and no keyed control. Keyed-function mortise locks such as the Accentra 8805FL Grade 1 storeroom lock with Arcadia lever, the Cal-Royal NM8080 Grade 1 storeroom lockset with interchangeable core option, and the Corbin Russwin ML2003 Grade 1 classroom lockset all restrict the outside lever and require a cylinder, so they change how the opening is secured rather than substituting for it.

No. The Baldwin 6318 is a working passage lock body with a latch, an ASA strike and a 1-1/4 inch by 8 inch faceplate, so the door latches shut. Emtek's mortise dummy sets, such as the 3102 Memphis, 3104 Hamilton, 3106 Manhattan and 3019 Brisbane, are dummy function trim with no operating latch and are used on inactive leaves or closet doors held by a catch.

The Baldwin 6318 requires a mortise pocket in the door edge. On a door with a standard bored prep, the Schlage PC10 is a Grade 1 non-keyed passage cylindrical lock with rose for 1-3/4 inch doors, which installs in a bored hole rather than a mortise pocket.

The Baldwin 6318 is a residential Estate Series body and is not built for ligature resistance. TownSteel's MRX-L-01 is a Grade 1 heavy-duty stainless steel anti-ligature lever mortise lockset in passage function, and the MRX-A-01 is the same passage function with ligature-resistant arch trim, both for 1-3/4 inch doors. Marks USA MAR5PDN is a Grade 1 hospital passage mortise push/pull paddleset that is ligature resistant and ADA compliant.

The Baldwin 6318003L is supplied left hand, so the hand has to be confirmed at order. If you would rather not hand the order, the Falcon MA101 Grade 1 heavy-duty mortise passage lock is field reversible, and the BEST 45H Series heavy-duty mortise lock body is also field reversible in public entrance function.

Finish 003, Polished Brass PVD. PVD is a plated coating that resists tarnish, which matters if the exposed faceplate on the door edge will be visible alongside brass trim on the rest of the opening.

No. The Baldwin 6318 is a mechanical passage body with no credential reading and no power requirement. Electronic mortise locks such as the Schlage CO-100 standalone keypad mortise lock in privacy function, the Alarm Lock DL3500CR Grade 1 Trilogy with 300 user codes in classroom function, and the TownSteel FME-2000 Grade 1 RFID classroom lockset add access control and are specified for 1-3/4 inch doors.

The Baldwin 6318 passage body leaves both sides always free. For office or entry control, the Cal-Royal NM8050 is a Grade 1 office/entrance mortise lockset with auxiliary deadlatch for 1-3/4 inch doors, and the Hager 3850E is a Grade 1 non-keyed office mortise lock with lever and escutcheon at a 2-3/4 inch backset.

The Baldwin 6318 is a latching passage body. For a deadbolt-only mortise pocket, the Sargent 4874 is a double cylinder mortise deadbolt with a 2-3/4 inch backset, and the Kaba Ilco 185 Series mortise lock is a deadbolt function supplied with no handing.
