Omnia 3911.32D – Frequently Asked Questions

1) Is the Omnia 3911 a mortise lock or a surface-applied pocket door latch?
It's a true mortise lock. The lockbody is cut into the edge of the pocket door rather than screwed to the face, which is why the 3-15/16 by 2-3/4 inch box dimension and the 6-5/16 inch faceplate matter before you order. Surface-mounted edge pulls and simple privacy latches, like the Rockwood 891 pocket door privacy latch, install with far less prep if you are retrofitting a door that has no mortise pocket cut.
2) I need a pocket door lock that works on doors of different thicknesses. Does the Omnia 3911 adjust?
The 3911 is specified around a fixed 2 inch backset with a 3-15/16 by 2-3/4 inch lockbody, so it is built to one prep. If your doors vary in thickness across the job, the Weslock 0577 rectangular privacy pocket door lock and the Weslock 0527 passage version both cover a 1-3/8 to 2 inch door thickness range, and the Pamex PF1 and PF2 cover 1-5/16 to 1-9/16 inches. The Deltana SDLA325 is an adjustable heavy-duty pocket door lock.
3) I'm building out a pocket door opening from scratch. Does the Omnia 3911 include the track and frame?
No. The 3911 is the lock only: mortise lockbody, faceplate, square door trim and strike plate. The pocket frame and the rolling hardware are separate purchases. The Orca Hardware PK1200 pocket door frame kit covers 1 inch or 1-3/4 inch doors, and the NGP SLAL250PD72 is a 72 inch aluminum pocket door track rated to 250 pounds.
4) My pocket door already has a mortise cut for a different brand lock. Will the Omnia 3911 cover the old prep?
Judge it by the faceplate and the box. The 3911 needs a mortise for a 3-15/16 by 2-3/4 inch body with a 6-5/16 by 5/8 inch faceplate, on a 2 inch backset. A shorter existing prep, like something cut for a Deltana SDL25 at 2-1/2 by 2-3/4 inches or an Emtek 2101 at 2-3/8 by 3-1/8 inches, is too small and will need to be enlarged. A longer prep, such as one cut for an Emtek #8 at 2-7/8 by 7-5/8 inches, will leave exposed wood the 6-5/16 inch faceplate cannot hide.
5) The Omnia 3911 needs a 2 inch backset - what pocket door lock works if my frame backset does not match?
Adjustable-backset locks solve that. The Weslock 0577 is a rectangular privacy pocket door lock with an adjustable backset and a full lip strike, fitting doors 1-3/8 inch to 2 inch thick, and the Weslock 0627 is the round passage version with the same adjustable backset and full lip strike. The Deltana SDLA325 is a heavy-duty adjustable pocket door lock at 3-1/4 inch by 2-1/4 inch in a privacy function. The Omnia 3911 is fixed at a 2 inch backset, so where the pocket frame prep is already cut to something else, one of the adjustable bodies is the retrofit.
6) I need a keyed pocket door lock - is the Omnia 3911 the right one?
For a keyed pocket door, look at the Emtek 2153 Narrow Modern Rectangular pocket door mortise lock at 2 inch by 7-1/4 inch, which is the keyed unit in the group. The Omnia 3911 is a residential mortise pocket door lock with square trim and a 2 inch backset. If the requirement on the drawing is key control at a pocket opening, the 2153 is the one specified for it.
7) What is the closest square-trim alternative to the Omnia 3911 pocket door lock?
The Orca Hardware PDLSQ is the nearest square-trim counterpart. The Omnia 3911 is a mortise pocket door lock with a square trim design and US32D stainless steel finish, while the Orca PDLSQ is a square pocket door lock built in a privacy function for bed and bath openings. If the square face is what you are matching and the opening needs a privacy turn, the PDLSQ covers it; the Omnia 3911 is the mortise-body square option.
8) I need a round trim instead of square for a pocket door lock - what should I order?
Two round-face options cover that. The Orca Hardware PDLRD is a round pocket door lock in a privacy function, and the Pamex PF2 is a round sliding door lock with a 2-3/8 inch backset that fits doors 1-5/16 inch to 1-9/16 inch thick. The Omnia 3911 is the square-trim mortise version, so if the other doors in the house carry round escutcheons, go to the PDLRD or PF2 rather than the 3911.
9) What is a simpler pocket door lock than the Omnia 3911 mortise for a closet or hall door that does not need to lock?
Passage-function pocket door pulls are the simpler build. The Deltana SDP25 is a 2-1/2 inch by 2-3/4 inch passage pocket door lock, the Emtek 2101 is a passage pocket door lock at 2-3/8 inch by 3-1/8 inch, and the Weslock 0527 is a rectangular passage version with no locking that fits doors 1-3/8 inch to 2 inch thick. The Omnia 3911 is the full mortise lockbody at 3-15/16 inch by 2-3/4 inch; on a closet or hall opening where nothing needs to latch privately, the passage units do the job with less door prep.
10) Is the Orca PK1200 pocket door frame kit a substitute for the Omnia 3911?
No - they are different parts of the same opening. The Orca Hardware PK1200 is a pocket door frame set for doors 1 inch or 1-3/4 inch thick, and the NGP SLAL250PD72 is a 72 inch aluminum pocket door track rated to 250 pounds. Those build and hang the pocket; the Omnia 3911 is the mortise lock and trim that goes into the door edge and face. On a new pocket opening you generally need one of the frame or track items plus a lock like the 3911, not one in place of the other.
11) Is the Omnia 3911 pocket door lock rated for commercial use or is it residential only?
Residential. Omnia lists the 3911 as a residential product, and the typical uses are bedroom suites, bathrooms, home offices and walk-in closets. For a commercial opening in an office or institutional building, look at a commercial-duty pocket door latch instead.
12) What finish does the Omnia 3911 pocket door lock come in?
One finish only: satin stainless steel, US32D. That's a brushed, non-reflective stainless tone that holds up to corrosion and hides fingerprints, which is why it works in bathroom and powder room pocket doors. If you need to match polished brass or oil-rubbed bronze on the rest of the doors, this one won't match, and an Emtek #8 Classic Arched brass pocket door mortise lock is the direction to look.
13) What's the difference between a passage and a privacy pocket door lock, and which do I need for a bathroom?
Privacy gives you a thumbturn or button that locks the door from inside, which is what a bathroom, powder room or bedroom needs. Passage has no locking at all and is for closets, pantries and hallway openings. Among pocket door hardware, the Deltana SDP25 and Weslock 0527 are passage function, while the Deltana SDL25, SDL60 and SDLA325, the Emtek 2102, the Orca PDLRD and PDLSQ, the Rockwood 891 and the Weslock 0577 are privacy function. Pick the function first, then match the trim shape and finish.
14) I manage apartments and want one pocket door lock across every unit. Is the Omnia 3911 a good standardization pick?
It standardizes well on new or consistently prepped doors: one finish (US32D satin stainless), one trim shape, one 2 inch backset, so every door gets the same cut and the same part number. Where it gets awkward is a mixed existing fleet with varied door thicknesses and old preps, because the 3911 is built to a single prep rather than an adjustable one. On a mixed portfolio, an adjustable-backset unit like the Weslock 0577 with its full lip strike is easier to fit across doors from 1-3/8 to 2 inches thick.
15) Which pocket door lock should I use on a bathroom or bedroom door instead of the Omnia 3911?
Several privacy-function units fit bed and bath openings. The Deltana SDL25 is a 2-1/2 inch by 2-3/4 inch privacy pocket door lock, the Deltana SDL60 is a 6 inch decorative privacy version, the Emtek 2102 is a privacy pocket door lock at 2-3/8 inch by 3-1/8 inch, and the Rockwood 891 is a pocket door privacy latch. The Omnia 3911 is the square-trim mortise build with a 2-3/8 inch diameter door trim; the privacy units above are specified by function for the bathroom and bedroom side.
16) What is the difference between the Omnia 3911 and the Emtek #8 Classic Arched pocket door mortise lock?
They differ in trim shape, footprint, and material. The Emtek #8 Classic Arched pocket door mortise lock is a brass unit in the Arched series with a 2-7/8 inch by 7-5/8 inch trim, so the plate is tall and curved. The Omnia 3911 uses a square trim of 2-3/8 inch diameter over a 3-15/16 inch by 2-3/4 inch mortise lockbody with a US32D stainless steel finish. Pick the arched brass plate for a traditional interior and the 3911 square stainless plate for a contemporary one.
17) My pocket door is thinner than standard - which lock fits a 1-5/16 inch door?
The Pamex PF1 square style sliding door lock and the Pamex PF2 round sliding door lock both fit doors 1-5/16 inch to 1-9/16 inch thick, with the PF2 carrying a 2-3/8 inch backset. The Weslock 0527 and 0577 cover 1-3/8 inch to 2 inch. The Omnia 3911 is the square-trim mortise lock with a 2 inch backset and a 3-15/16 inch by 2-3/4 inch body, so on a thin slab the Pamex pair is the range to work from.
18) I am standardizing pocket door hardware across a multi-family property - can I mix the Omnia 3911 with the Deltana or Weslock locks?
They are not interchangeable trims, so standardize by function and face. The Omnia 3911 carries square trim at 2-3/8 inch diameter over a 3-15/16 inch by 2-3/4 inch mortise body with a 6-5/16 inch by 5/8 inch faceplate. The Deltana SDL25 privacy runs 2-1/2 inch by 2-3/4 inch and the Deltana SDL60 is 6 inch, while the Weslock 0577 privacy and 0627 passage both use an adjustable backset with a full lip strike. Different footprints mean different door prep, so pick one family for the bath and bedroom doors and the matching passage unit for closets rather than mixing bodies across the same building.
19) What does the square trim on the Omnia 3911 look like and how much of the door face does it cover?
The door trim is square in shape with a 2-3/8 inch diameter, so it sits as a compact plate on the door face rather than a long vertical escutcheon. If you want the same square look from another brand, the Orca Hardware PDLSQ is a square pocket door lock and the Pamex PF1 is a square style sliding door lock. For round trim, the Orca PDLRD and Pamex PF2 are the round-face equivalents.
