Omnia 3911S.3 – Frequently Asked Questions

1) Will the Omnia 3911S pocket door mortise lock fit my existing pocket door prep?
The 3911S runs a 2 inch backset with a lockbody measuring 3-15/16 inches by 2-3/4 inches, so the pocket in the door edge has to be cut to take that body. The faceplate is 6-1/4 x 3/4 inches and the strike is 3-9/16 x 3/4 inches. If your existing door was routed for a smaller surface-mount pocket door latch, this is a deeper mortise and the pocket will need enlarging. Match the faceplate footprint first, then the backset.
2) My pocket doors vary in thickness across the building - is the Omnia 3911S the right choice or is there an adjustable option?
The Omnia 3911S is built to fixed dimensions: a 2 inch backset with a 3-15/16 inch by 2-3/4 inch lockbody. Where a fleet of doors varies, an adjustable-backset unit standardizes the order: the Weslock 0577 is a rectangular privacy pocket door lock with adjustable backset and full lip strike for doors 1-3/8 inch to 2 inch thick, the Weslock 0627 is the round passage version with adjustable backset and full lip strike, and the Deltana SDLA325 is a heavy-duty adjustable pocket door privacy lock at 3-1/4 inch by 2-1/4 inch.
3) Is the Omnia 3911S a substitute for a pocket door frame kit or track?
No. The Omnia 3911S is the lock only - lockbody, 6-1/4 inch by 3/4 inch faceplate and 3-9/16 inch by 3/4 inch strike, mortised into the door edge. The carriage the door hangs and rolls on is a separate purchase: the Orca Hardware PK1200 pocket door frame kit covers 1 inch or 1-3/4 inch door thickness, and the NGP SLAL250PD72 is a 72 inch aluminum pocket door track rated up to 250 pounds. A new pocket door opening needs both the frame or track and a lock like the 3911S.
4) What is the closest alternative to the Omnia 3911S if I need a keyed pocket door mortise lock instead of one without a cylinder?
The Omnia 3911S is a solid brass pocket door mortise lock with a 2 inch backset, 2-3/8 inch square trim, a 3-15/16 inch by 2-3/4 inch lockbody, a 6-1/4 inch by 3/4 inch faceplate and a 3-9/16 inch by 3/4 inch strike, built for residential pocket doors. For a keyed opening, the Emtek 2153 Narrow Modern Rectangular Pocket Door Mortise Lock is a keyed pocket door mortise lock with a 2 inch by 7-1/4 inch trim. The Emtek trim is a tall narrow rectangle rather than the Omnia's 2-3/8 inch square, so the door face cutout and mortise pocket differ and the two are not a drop-in swap for each other.
5) The pocket door is a closet and does not need to lock - what should I use instead of the Omnia 3911S?
The Omnia 3911S is a mortise pocket door lock set with lockbody, faceplate and strike. For a closet or hall door that only needs to latch, a passage function unit is the simpler part: 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 with 2-3/8 inch by 3-1/8 inch trim, and the Weslock 0527 is a rectangular passage pocket door lock with no locking, for doors 1-3/8 inch to 2 inch thick. The Emtek 2101 trim width matches the 2-3/8 inch dimension of the Omnia, though its 3-1/8 inch height is taller than the Omnia square plate.
6) Should I buy a mortise pocket door lock or a surface-mount pocket door latch?
A mortise unit like the Omnia 3911S buries the lockbody inside the door edge, so the only thing on the door face is the trim. That takes a deeper rout, but it gives you a real latch in the edge. Surface-style pocket door pulls such as the Rockwood 891 privacy latch or the Orca Hardware PDLSQ square privacy lock are simpler to install into a shallower prep. Pick the mortise if you are building or replacing the door anyway; pick the simpler pull if you are working with what is already cut.
7) Will the strike from my old pocket door lock work with the Omnia 3911S?
Use the strike that ships with the 3911S. It is 3-9/16 x 3/4 inches and cut to match this lockbody. An older strike from a different maker is unlikely to line up with the latch position set by the 2 inch backset, and mismatching them is how you end up with a door that will not stay shut.
8) What is the difference between the Omnia 3911S and the round pocket door locks like the Pamex PF2 or Orca PDLRD?
The difference is the trim shape and what it leaves behind on the door face. The Omnia 3911S uses a 2-3/8 inch square trim in solid brass. The Pamex PF2 is a round sliding door lock with a 2-3/8 inch backset for doors 1-5/16 inch to 1-9/16 inch thick, and the Orca Hardware PDLRD is a privacy function round pocket door lock. Note the Omnia is a 2 inch backset while the Pamex PF2 is 2-3/8 inch, so the edge bore location is not the same. If existing doors are already cut for a square plate, a round trim will not cover the same footprint.
9) I want a larger decorative plate than the Omnia 3911S for a pair of pocket doors in a formal room - what else is there?
The Omnia 3911S trim is a 2-3/8 inch square in solid brass. For a larger decorative face, the Deltana SDL60 is a decorative pocket door privacy lock with a 6 inch plate, and the Emtek #8 Classic Arched pocket door mortise lock is a brass unit with 2-7/8 inch by 7-5/8 inch arched trim. Both present a much taller plate than the Omnia square, so the door face preparation and any existing mortise will need to be matched to the new trim rather than reused.
10) Can I use a pocket door privacy latch like the Rockwood 891 in place of the Omnia 3911S?
They solve different halves of the problem. The Omnia 3911S is a full mortise lock set with a 3-15/16 inch by 2-3/4 inch lockbody, faceplate and strike, so it both latches the door and provides the privacy function from one mortise. The Rockwood 891 is a pocket door privacy latch with a privacy function, an edge-mounted latching device rather than a mortise lockbody with square door trim. Where the door already has its pull hardware and only privacy is being added, the 891 is the narrower fix; where the whole lock is being supplied, the 3911S carries the lockbody, faceplate and strike together.
11) I need a privacy pocket door lock in oil-rubbed bronze or polished nickel - which units besides the Omnia 3911S should I look at?
The Omnia 3911S is offered in Black Oil-Rubbed, Polished Nickel Plated, Satin Nickel Plated, Polished Chrome Plated, Polished Brass and Shaded Bronze, all on solid brass. On the privacy function specifically, the comparable units are the Deltana SDL25 at 2-1/2 inch by 2-3/4 inch, the Deltana SDLA325 heavy-duty adjustable at 3-1/4 inch by 2-1/4 inch, the Emtek 2102 with 2-3/8 inch by 3-1/8 inch trim, and the Orca Hardware PDLSQ square and PDLRD round units. Match the trim footprint to the door prep first, then the finish.
12) Emtek 2101 versus Emtek 2102 versus the Omnia 3911S - what actually separates them?
Function and trim. The Emtek 2101 is the passage version and the Emtek 2102 is the privacy version, both with 2-3/8 inch by 3-1/8 inch trim. The Omnia 3911S is a solid brass mortise pocket door lock with a 2-3/8 inch square trim, a 2 inch backset, a 3-15/16 inch by 2-3/4 inch lockbody and a 6-1/4 inch by 3/4 inch faceplate. The two Emtek units share a trim footprint with each other, so they interchange on the same door prep; the Omnia's square plate and mortise lockbody dimensions are its own.
13) What finishes does the Omnia 3911S pocket door lock come in?
Six: polished brass, polished nickel plated, satin nickel plated, polished chrome plated, black oil-rubbed, and shaded bronze. All six are the same lock, so if you are standardizing a house or a floor of units you can run one trim profile and vary the finish door to door.
14) Is the Omnia 3911S solid brass all the way through or just plated?
Solid brass is the base material of the 3911S. The polished brass and shaded bronze are finishes on that brass; the nickel and chrome options are plated over it. Brass holds up against humidity, which is why this works on a bathroom or powder room pocket door.
