Omnia 4036/A26D – Frequently Asked Questions

1) What lock functions can I get on the Omnia 4036 lever lockset?
Eight functions are offered: Standard, Double Cylinder, Storeroom, Panic-Proof, Classroom, Privacy, Passage, Pair Dummy and Single Dummy. That range means one 4036 lever design can run a whole house or a small building: keyed entry at the front door, privacy at the bed and bath, passage at hall and closet, and dummy trim on the inactive leaf of a pair, all matching visually.
2) Which Omnia 4036 function should I pick for a bedroom or bathroom versus a front entry door?
Bed and bath doors take the Privacy function, which locks from inside without a key. Front entry doors take Standard or Double Cylinder; double cylinder needs a key on both sides, which is the choice for a door with glass beside or in it, though many local codes restrict double cylinder on a primary egress door. Closets and hall doors take Passage, which is latch only with no locking at all. An inactive leaf on a pair takes the Pair Dummy or Single Dummy.
3) How much room do I need in the door edge for the Omnia 4036 mortise lockset?
The 4036 is a mortise lock, so the door needs a rectangular pocket routed into the edge, not the two round bores a cylindrical lock uses. The trim measures 8-1/4 by 2 by 2-1/2 inches, with the 2-1/2 inch figure given as projection. On a new door a mortise jig is the usual way to cut the pocket. If the door already has a 2-1/8 inch cross bore for a knob or a cylindrical lever, the 4036 will not go in without a new door or a filler.
4) I need a mortise lock with a classroom function for a school. Is the Omnia 4036 classroom version the right one?
Probably not for an actual school. The 4036 offers a Classroom function, but it is a residential lockset. An institutional opening usually needs Grade 1: the Cal-Royal NM8070 is a Grade 1 classroom mortise with auxiliary deadlatch for 1-3/4 inch doors, the Corbin Russwin ML2003 is a Grade 1 classroom mortise, and the Marks USA LA318GJ adds a classroom security indicator with an ANSI strike. The 4036 Classroom suits a home office or studio where the keyed-outside, always-free-inside behaviour is what you want.
5) Is a mortise deadbolt the same thing as the Omnia 4036 double cylinder function?
No. The Omnia 4036 double cylinder function is a complete lever lockset with plates, so the lever, latch and cylinders come as one assembly. A mortise deadbolt is bolt only with no lever: the Sargent 4874 is a double cylinder mortise deadbolt with a 2-3/4 inch backset in the 4870 Series, and the Kaba Ilco 185 Series is a deadbolt function mortise lock with no handing. If the door still needs a latch and a handle, the deadbolt does not replace the 4036 - it supplements it.
6) My door is prepped for a cylindrical lock, not a mortise pocket - can I use the Omnia 4036?
No. The Omnia 4036 is a mortise lock, which needs a rectangular pocket cut into the edge of the door rather than the two bores a cylindrical lock uses. For a cylindrical prep, the Schlage PC10 is a Grade 1 non-keyed passage cylindrical lock with a rose for 1-3/4 inch doors. Cutting a mortise pocket into a door already bored for cylindrical hardware is a door modification, not a swap.
7) I need the mortise lock to release on an access control signal - what replaces the Omnia 4036 on a card-reader opening?
The Omnia 4036 is a mechanical lever lockset and does not take an electrified input. For access control, the Schlage 03A electric lock/unlock outside lever mortise lock runs on 12/24VDC, is keyed outside with request to exit, in a corridor function heavy duty for 1-3/4 inch doors. The Command Access ML190 Series is a motorized mortise lock with field selectable fail safe or fail secure operation on 24VDC in a storeroom function, and the BEST 45HW Series is a wired electromechanical mortise lock with 12V/24V operation. For a credential reader built into the lock, the Dormakaba Saffire LX-I-M002 is an electronic RFID mortise lockset with BLE mobile access at BHMA Grade 2.
8) Will the Omnia 4036 work on an aluminum storefront door?
No. The Omnia 4036 is a residential mortise lever lockset with plates sized 8-1/4 inches overall by 2 inches wide, which suits a stile-and-rail or solid door leaf rather than a narrow aluminum stile. For storefront, the Alarm Lock DL1300NW Trilogy Networx wireless electronic mortise lock is built for Adams Rite deadlatches, the Dormakaba E-Plex 2066 is a wide stile mortise lock, and the Kaba Ilco BR Series is a glass door bottom rail lock.
9) What mortise lockset do I use in a behavioral health or hospital room where a lever is a ligature risk?
The Omnia 4036 uses a lever handle. Where a projecting lever is not acceptable, the TownSteel MRX-A-01 is a Grade 1 heavy duty ligature resistant arch trim mortise lockset in satin stainless steel, passage function for 1-3/4 inch doors, and the MRX-L-01 is the anti-ligature lever version at the same grade and door thickness. The Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset, ligature resistant and ADA compliant in satin stainless steel.
10) Does the Omnia 4036 carry a fire rating for a rated door assembly?
For a rated opening, specify a lock the rating is stated for. The Falcon MA101 Grade 1 heavy duty mortise passage lock is fire rated, the Schlage Electronics LEBMB-ADD mortise lock is rated 3 hours at Grade 2 for 1-3/4 inch doors, and the Schlage Electronics LEMD-GRW ENGAGE Series wireless mortise lock is Grade 1 with a 3 hour rating. Match the lock's rating to the label on the door and frame before ordering.
11) What do I order for the inactive door of a double door with the Omnia 4036?
Order the Pair Dummy for a set of levers on both faces of the inactive leaf, or the Single Dummy for one lever on one face only. Dummy trim does not latch, so the inactive leaf needs flush bolts or a surface bolt to hold it shut, ordered separately. The dummy comes in the same polished brass, polished chrome and satin chrome as the working leaf, so the pair matches.
12) What is the difference between the Omnia 4036 mortise set and a cylindrical lever lock?
The 4036 puts the whole lock case inside a pocket in the door edge, which gives a longer, better supported latch and lets one case carry a latch and, in the keyed versions, a deadbolt. A cylindrical lever like the Schlage PC10 passage lock mounts through two round bores and is far quicker to install in an existing door. Pick mortise for a new or purpose-prepped door where you want the heavier case and the plate trim look; pick cylindrical when you are replacing hardware in a door already bored for it.
13) The Omnia 4036 storeroom function is on my quote - what is the commercial storeroom equivalent?
The Omnia 4036 storeroom function is available in polished brass, polished chrome plated and satin chrome plated. On the commercial side, the Cal-Royal NM8080 is a Grade 1 heavy duty storeroom mortise lockset with an interchangeable core option for 1-3/4 inch doors, and the Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series with an Arcadia lever. The Baldwin 6310 knob by knob mortise lock body is an entrance/storeroom function on a 2-1/2 inch backset for doors 1-3/8 inch and over.
14) What is the equivalent of the Omnia 4036 panic-proof function for a dormitory or corridor door?
The Omnia 4036 offers a panic-proof function, where turning the inside lever retracts both latch and bolt in one motion for free egress. The Sargent 7925 is the commercial parallel: a Grade 1 heavy duty dormitory exit function mortise lock in the 7900 Series with rose trim and a single cylinder deadbolt, in a corridor/dormitory function. The BEST 45H heavy duty mortise lock body in a public entrance function covers the same corridor traffic on a lock body basis.
15) I only need a non-latching pull on one leaf - is there a dummy mortise trim instead of a full 4036 lockset?
The Omnia 4036 does include single dummy and pair dummy functions among its function choices. If the finish direction is different, the Emtek 3019 Brisbane, 3102 Memphis, 3104 Hamilton and 3106 Manhattan are all mortise entrance locksets in a dummy function, each a separate design series. The Schlage L0170 is a half dummy trim in the L Series, a Grade 1 heavy duty non-keyed mortise lever for 1-3/4 inch doors.
16) I want keyless entry on the same mortise prep the 4036 would go into - what are the options?
The Omnia 4036 is a key-operated mortise lockset with a lever. For keyless operation in a mortise body, the Alarm Lock DL3500CR is a Grade 1 Trilogy electronic mortise lock with 300 user codes in a classroom function for doors 1-5/8 to 1-7/8 inch, and the DL2700CR is a Grade 1 Trilogy T2 electronic mortise lock, classroom function, weatherproof, over the same 1-5/8 to 1-7/8 inch thickness range. The Dormakaba E-Plex 2066 is an electronic pushbutton keyless mortise lock for wide stile doors, and the BEST 45HZ EZ Series is an electronic keypad mortise lock with key override.
17) If I only need a passage function and not the full keyed 4036, what is a simpler mortise option?
The Omnia 4036 is offered in a passage function as well as keyed functions. If passage is all the opening needs, the Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock for 1-3/4 inch doors, and the Falcon MA101 is a Grade 1 heavy duty mortise passage lock in the MA Series with field reversible operation and a fire rating. The Hager 3810S is a Grade 1 passage mortise lock with a rose and 2-3/4 inch backset for doors 1-3/4 to 2-1/2 inch, while the 3810E is the same passage function with an escutcheon instead of a rose.
18) What is the difference between the Omnia 4036 privacy function and a privacy mortise lock with a deadbolt?
The Omnia 4036 privacy function locks the lever from the inside as part of the lever lockset with plates. The Cal-Royal NM8440 is a Grade 1 heavy duty privacy mortise lockset that carries a deadbolt as part of the function, for 1-3/4 inch doors. The Hager 3840S is a Grade 1 privacy/bed/bath mortise lock with a 2-3/4 inch backset for doors 1-3/4 to 2 inch. Choose on whether the bathroom or bedroom opening is specified with a throwing bolt or a lever lock only.
19) The Omnia 4036 requires handing at order - which mortise locks are field reversible instead?
The Omnia 4036 is ordered left handed or right handed, so the handing is fixed when the part is picked. If you would rather stock one part for both hands, the BEST 45H Series heavy duty mortise lock body in a public entrance function is field reversible, and the Falcon MA101 Grade 1 heavy duty mortise passage lock in the MA Series is field reversible as well. The Kaba Ilco 185 Series mortise locks have no handing.
20) Can I put the Omnia 4036 on a 1 inch thick ornamental iron gate door?
The Omnia 4036 is a solid brass residential mortise lever lockset with plates 8-1/4 inches overall, sized for standard residential door leaves. For a 1 inch section, the Marks USA 21AC is an entrance double cylinder Unilock ornamental iron mortise lock with a round knob for 1 inch doors, and the 22AC is the same style of ornamental iron mortise lock in the 22 Series, also 1 inch. Those are built for the narrow section an iron gate or screen door presents.
21) I searched for a mortise thumbturn and got the Omnia 4036 - are those the same part?
No. The Omnia 4036 is a complete mortise lever lockset with plates and a lever handle. A mortise thumbturn is the small inside turn piece only: the Sargent 130KB is a standard duty mortise thumbturn in the 8200 Series, and the Sargent 130W is a standard duty mortise thumbturn with a round backplate in the 7800 Series. Order those to replace a broken turn on an existing lock, not to lock a door on their own. The Falcon MESC600DT is likewise trim only, a fire rated dummy escutcheon lever trim for M9900 Series exit devices.
22) Is a lever easier to use than a knob for accessibility on an entry door?
A lever is what accessibility guidance asks for, because it opens with a closed fist or a forearm and needs no grasping or twisting. The 4036 is a lever set with plate trim throughout, in all three finishes and all eight functions, so there is no knob version to weigh up. If someone in the household has limited hand strength, the lever is the reason to choose this over a knob-style mortise set like the Baldwin 6301 knob by knob.
23) Is the Omnia 4036 solid brass all the way through, or plated?
Solid brass is the base material of the 4036, with the chrome versions plated over it. Solid brass resists corrosion better than a plated pot metal set, which is why it holds up on a front entrance that sees weather. The polished brass finish is the bare brass tone; polished chrome and satin chrome are plated over the same brass body.
24) Can I get the Omnia 4036 look as a decorative dummy set from another brand if I want a different lever style?
Emtek's mortise dummy sets are the closest alternative in the same residential decorative space: the 3019 Brisbane, 3102 Memphis, 3104 Hamilton and 3106 Manhattan are all brass mortise entrance dummy sets in distinct handle styles. They are dummy function only, so they do not replace a working 4036 entry or privacy set, only the non-latching trim on an inactive leaf.
