Emtek Modern Brass Tubular Single Point Lockset with Helios Lever - Single Cylinder

The Helios lever single point lockset covers doors from 1-3/8 to 1-3/4 inches. The lock ships set up for 1-3/4 inch as standard, which is the usual exterior door, so if you are putting it on a 1-3/8 inch door (or anything thicker than 1-3/4) you need to call out the door thickness when you order. There is a door thickness field on the order for exactly that.

Both backsets are available: 2-3/8 inch and 2-3/4 inch. The latch supplied by default is 2-3/8 inch, so on an existing door prepped at 2-3/4 inch you have to select the 2-3/4 inch backset at order time or the latch will not reach the edge prep. Measure from the door edge to the center of the 2-1/8 inch cross bore to tell which one you have.

Yes. It is a tubular lock built for the standard 2-1/8 inch cross bore, so a door already prepped for a common residential bored lockset takes it without redrilling the face. What you do have to match is the backset (2-3/8 or 2-3/4 inch) and the handing. It is a single point lockset, meaning one hole does both the lever and the key cylinder, so there is no separate deadbolt bore involved.

Handing is required. The Helios lever is offered left hand and right hand, and it is not field reversible on the order form, so you pick one. Stand outside the door (the key side): if the hinges are on your left it is left hand, hinges on the right is right hand. Get it wrong and the lever points the wrong way.

Yes. The lock comes standard with a Schlage C keyway, and a Weiser WR5 cylinder is a no-cost substitution, so it can be keyed into an existing Weiser system. Pick the Weiser (WR5) keyway option when ordering. If your building is on Schlage C, leave it standard.

Both. Keyed alike and keyed different are offered at no charge, and there is a keying-to-code field where you enter your existing key code so the new locks run on keys you already carry. That is the route if you are replacing a few doors in a building that is already on one key.

Both are single cylinder brass sideplate lever locksets. The Emtek Helios set is a tubular entry lockset in solid brass with the key cylinder in the exterior sideplate and a lever on each side, offered in seven finishes from Oil Rubbed Bronze (US10B) through Unlacquered Brass (US3NL), with left hand and right hand builds and a choice of Modern Rectangular or Annapolis trim. The Omnia D12036A is a single cylinder deadbolt lever lockset of solid brass construction, so the keyed security comes from a deadbolt paired with the lever plates rather than from the tubular latch. Choose on which locking mechanism the opening calls for: a keyed tubular entry latch, or a lever plate set built around a deadbolt.

The Emtek Helios sideplate lockset is a single cylinder entry set, meaning key outside and thumbturn or free egress inside. If the opening genuinely calls for a key on both faces, the Omnia D12036AC is a double cylinder deadbolt lever lockset in solid brass with a sideplate design. Confirm the local code and the occupancy before specifying double cylinder on any egress door, since many jurisdictions restrict key-both-sides on a required exit.

The lever and the function are the same; the sideplate trim shape differs. The 5302 carries the Modern Rectangular trim style and the 5308 carries the Annapolis trim style. Both are single cylinder entry, key outside and thumbturn or lever inside. Choose on how the plate should look next to the rest of your hardware.

Seven finishes: Oil Rubbed Bronze (US10B), Polished Nickel (US14), Satin Nickel (US15), Flat Black (US19), Polished Chrome (US26), Unlacquered Brass (US3NL) and Satin Brass (US4). Two brass options, and they behave differently: US4 satin brass holds its tone, while US3NL unlacquered brass is left bare and will patina with handling. If you are matching existing living-finish brass, US3NL is the one that ages with it. There is also a split finish option if you want a different finish inside and out.

The Helios lever lockset is single cylinder: key on the outside, turn on the inside, so you can always get out without a key. That is what most codes want on an egress door. A double cylinder takes a key on both sides, which some people specify next to glass so a broken pane does not let someone reach the inside turn, at the cost of needing a key to get out. If you want that, the Omnia D12036AC is a double cylinder deadbolt lever lockset in solid brass. The matching Omnia single cylinder is the D12036A.

The Emtek Helios single cylinder sideplate lockset is a residential grade brass tubular entry set in a contemporary style, intended for residential entry and interior doors. Heavy commercial corridor traffic is a different duty class. The Omnia D12036A, D12036AC and D12036PD are likewise solid brass decorative lever sets rather than commercial cylindrical locks. For a high traffic corridor opening, specify a commercial cylindrical or mortise lock and reserve these brass sideplate sets for residential entries, executive suites, hospitality guest doors and multi-family unit doors where the look matters.

For a non-latching opening such as a closet, pantry, or an inactive leaf of a pair, the Omnia D12036PD is a solid brass dummy deadbolt lever lockset with plates on 5-1/2 inch center to center spacing. It is a double dummy, so the levers are fixed and there is no latch or cylinder. The Emtek Helios sideplate lockset is a keyed single cylinder entry function and is bored for an operating tubular latch, so it is the wrong choice for a door that only needs a pull. Pairing a dummy set on the closet with a keyed set on the entry is how you keep one lever look across a run of doors.

No. The Omnia D12036PD is a double dummy, a fixed lever on plates with no latch and no cylinder, so it cannot secure or latch a door. The Emtek Helios sideplate set is a keyed entry function with a tubular latch and a single cylinder. It looks like a substitute in a photograph because both are brass lever sets on plates, but only the Helios set operates a latch. For a keyed swap, look to the Omnia D12036A single cylinder set instead.

Brass, through the substrate, not a plated pot metal casting. That matters on an exterior door where the finish takes weather and on a rental where the lever takes traffic, and it is why the unlacquered version can be left to patina instead of flaking. The styling is contemporary, with a rectangular sideplate behind the lever.

No power, no wiring, no batteries. It is a mechanical tubular lock operated by key outside and lever inside, so nothing to network and nothing to fail when the power drops.

All four are solid brass lever sets on plates, so they read as one family across a run of doors. The Emtek Helios sideplate lockset covers the keyed entry openings as a single cylinder tubular set and comes in seven finishes including Satin Nickel (US15), Flat Black (US19), Polished Chrome (US26) and Satin Brass (US4). The Omnia D12036A handles single cylinder deadbolt openings, the D12036AC handles double cylinder openings, and the D12036PD covers dummy applications at 5-1/2 inch center to center. Match the finish call on each line item, since finish coding differs between manufacturers even when the name is similar.
