Omnia 3910S.10B – Frequently Asked Questions

1) How big a hole does the round trim on the Omnia 3910S pocket door lock cover?
The round trim is 2-3/8 inches in diameter, so it covers a 2-3/8 inch face bore and no more. If you are replacing a larger round or rectangular pocket door plate you will see the old cutout around the edges. Emtek's 2101 passage and 2102 privacy pocket door locks run 2-3/8 by 3-1/8 inches, and the Emtek #8 Classic Arched mortise lock is 2-7/8 by 7-5/8 inches, so those cover progressively more face area if the existing prep is oversized.
2) Will the Omnia 3910S pocket door lock work on a barn door or a bypass slider?
No. The 3910S is a mortise lock that latches into a jamb strike, which means the door has to close into a frame, the way a pocket door does. A surface-mounted barn door slides past the wall with no jamb to receive a 3-9/16 inch strike, so there is nothing for it to latch into. Keep this one for pocket doors running in a frame.
3) Which pocket door lock should I use if the backset has to be adjustable in the field?
The Omnia 3910S is built to a fixed 2 inch backset. If the mortise depth on the doors varies and you need the trim to land consistently, the Deltana SDLA325 is a heavy-duty adjustable pocket door lock with a 3-1/4 inch by 2-1/4 inch privacy trim, and the Weslock 0577 is a rectangular privacy pocket door lock with adjustable backset and a full lip strike for doors 1-3/8 inch to 2 inch thick. On a passage opening, the Weslock 0627 is the round adjustable-backset equivalent.
4) I need a square trim pocket door lock instead of a round one - what takes the place of the Omnia 3910S?
The Omnia 3910S is built around 2-3/8 inch diameter round trim, so it will not give you a square face. For square trim, the Pamex PF1 is a square style sliding door lock fitting doors 1-5/16 inch to 1-9/16 inch thick, and the Orca Hardware PDLSQ is a square pocket door lock in privacy function. If you want a rectangular face rather than square, the Weslock 0527 is a rectangular passage pocket door lock for 1-3/8 inch to 2 inch doors and the Weslock 0577 is the rectangular privacy version with adjustable backset and full lip strike.
5) What is the difference between the Omnia 3910S pocket door mortise lock and the Pamex PF2 round sliding door lock?
Both are round-trim pocket door locks. The Omnia 3910S uses 2-3/8 inch diameter round trim over a mortise lockbody measuring 3-15/16 inches long by 2-3/4 inches deep, with a 2 inch backset and solid brass construction. The Pamex PF2 is a round sliding door lock with a 2-3/8 inch backset and fits doors 1-5/16 inch to 1-9/16 inch thick. If the door slab is thicker than 1-9/16 inch, the PF2 door thickness range rules it out and the Omnia 3910S is the round-trim option to spec.
6) What is the closest round pocket door lock to the Omnia 3910S if I need a stated privacy function for a bathroom?
For a bath or bedroom pocket door where the trim needs to stay round, the Orca Hardware PDLRD is a round pocket door lock in privacy function, and the Weslock 0627 is a round pocket door lock in passage function with adjustable backset and full lip strike if that same opening does not need to lock. The Omnia 3910S carries 2-3/8 inch round trim on a solid brass mortise body with a 2 inch backset, so the trim profile reads the same across the three; the difference is which function the opening calls for.
7) The opening needs a keyed pocket door lock - what should I use instead of the Omnia 3910S?
For a keyed pocket door opening, the Emtek 2153 Narrow Modern Rectangular pocket door mortise lock is offered keyed, with a 2 inch by 7-1/4 inch trim. That is a tall narrow rectangular face rather than the 2-3/8 inch round trim of the Omnia 3910S, so the door edge and face prep are different and the 7-1/4 inch trim length needs stile room. If you want a larger decorative face without going keyed, the Emtek #8 Classic Arched pocket door mortise lock is a brass unit with a 2-7/8 inch by 7-5/8 inch arched trim.
8) Does the Omnia 3910S come with a strike, or do I have to order one separately?
A matching strike plate is included, 3-9/16 inches long by 3/4 inch wide. It matches the 3/4 inch faceplate width, so the jamb mortise and the door edge mortise are cut to the same width. Nothing else is needed on the strike side.
9) Is a mortise pocket door lock like the Omnia 3910S the right choice, or should I use a simpler surface privacy latch?
A mortise pocket lock buries a full lockbody in the door edge, which is why the 3910S needs a 3-15/16 by 2-3/4 inch pocket routed into the stile. You get a proper mortise mechanism and a solid brass body. If the door is already hung and you do not want to rout a deep pocket, a shallower privacy latch such as the Rockwood 891 pocket door privacy latch or the Deltana SDL25 at 2-1/2 by 2-3/4 inches is the lighter-prep route. Go mortise when the door is on the bench or the prep already exists.
10) Is the Omnia 3910S rated for a commercial building or is it a residential lock?
Residential. The 3910S is built for residential pocket door work, custom homes and remodels. For a high-traffic commercial opening you want a heavier-duty pocket door lock rather than this one.
11) I am building the pocket door opening from scratch. What else do I need besides the Omnia 3910S lock?
The 3910S is lock and strike only. The pocket frame and the rolling hardware are separate: Orca Hardware's PK1200 pocket door frame kit handles 1 inch or 1-3/4 inch doors, and the NGP SLAL250PD72 is a 72 inch aluminum pocket door track rated to 250 pounds. Order the frame and track to suit the door leaf, then the lock to suit the finish on the rest of the room.
12) My pocket door is a thin 1-3/8 inch leaf. Is the Omnia 3910S too much lock for it?
The 3910S needs a 2-3/4 inch deep mortise pocket in a stile with a 2 inch backset, which is a lot of material to remove from a thin or hollow-core leaf. On light doors the shallower options are the safer prep: Weslock's 0527 passage and 0577 privacy pocket door locks cover 1-3/8 to 2 inch doors, and the Pamex PF1 and PF2 cover 1-5/16 to 1-9/16 inches. Save the Omnia mortise body for a solid leaf that can take the cut.
13) Is there a simpler pocket door latch than the Omnia 3910S mortise lock?
Yes. The Rockwood 891 is a pocket door privacy latch, and the Deltana SDL25 is a pocket door lock with a 2-1/2 inch by 2-3/4 inch privacy trim - both are compact privacy units rather than a full mortise lockbody. The Omnia 3910S is a mortise lock with a 3-15/16 inch by 2-3/4 inch lockbody, a 6-1/4 inch by 3/4 inch faceplate and a matching 3-9/16 inch by 3/4 inch strike, so it takes a deeper edge mortise and a longer faceplate routing than the compact latches do.
14) Is the Emtek 2102 pocket door lock a drop-in match for the Omnia 3910S?
They are close in trim size but not the same part. The Emtek 2102 is a privacy pocket door lock with a 2-3/8 inch by 3-1/8 inch trim, and the Emtek 2101 is the passage version at the same 2-3/8 inch by 3-1/8 inch size - both are rectangular footprints. The Omnia 3910S trim is a 2-3/8 inch diameter round, so the trim cutout and screw pattern differ even though the 2-3/8 inch dimension matches. Treat a swap between them as a new mortise and trim prep, not a plate-for-plate change.
15) Will the Orca PK1200 pocket door frame kit or the NGP SLAL250 track work in place of the Omnia 3910S?
No - those solve a different part of the opening. The Orca Hardware PK1200 is a pocket door frame set for 1 inch or 1-3/4 inch doors, and the NGP SLAL250PD72 is a 72 inch aluminum pocket door track rated up to 250 pounds; they carry and pocket the door. The Omnia 3910S is the mortise lock that mortises into the door edge and latches it, with a 6-1/4 inch by 3/4 inch faceplate and matching strike. A pocket door opening typically needs both the frame or track and a lock like the 3910S.
16) Is the Omnia 3910S solid brass all the way through or just brass plated?
Solid brass construction, not a plated pot-metal body. That matters on a pocket door because the lockbody sits inside the stile where you cannot service it easily, and brass will not corrode in a bathroom or a coastal house. Plated finishes like polished nickel and polished chrome are applied over that brass base.
