Emtek 8070 Belmont 3-5/8" C-to-C Keyed Sideplate Lockset, Passage/Single Keyed - Brass Tubular

Yes. The 8070 Belmont uses one standard 2-1/8 inch cross bore and fits doors 1-3/8 to 1-3/4 inches thick, so it drops onto a door already prepped for a normal bored lockset. Because it is a sideplate design, the plate covers a taller area of the face than a round rosette, so check that the existing prep on the stile is clean above and below the bore.

Both work. The latch is adjustable for 2-3/8 or 2-3/4 inch backset, and backset is a required choice when you order. The standard latch ships for 2-3/8 inch, so if your existing bore is 2-3/4 inches off the edge you have to specify that. Those are the two common residential backsets, and measuring center of the bore to the door edge tells you which you have.

Handing is required on the order, right hand or left hand. Emtek calls for handing on any leverset, and since this is a keyed entry set with a sideplate you specify it regardless. Stand outside the door on the side you key from: if the hinges are on your right it is right hand, hinges on the left is left hand.

It ships as a complete set: knob or lever, latch and strike plate. It is a single cylinder entry function, meaning key outside and thumbturn or button inside, so the lockset itself locks the door. It is not a deadbolt, so if the opening needs a second point of security you order a deadbolt separately.

Yes. Keying is a required selection, keyed different or keyed alike, and you can also supply a key code to have them cut to an existing key. That is how you get a front, back and side door on one key without rekeying after install.

The 8070 Belmont is a single cylinder entry set, keyed from the outside only. For an opening that must be keyed from both sides, such as a door with glass beside the lock, the Omnia D12036AC Double Cylinder Deadbolt Lever Lockset is the sideplate option with a cylinder on each face, in solid brass with a sideplate design. Double cylinder hardware is restricted on some egress doors, so verify the local code for the opening before specifying it.

The Omnia D12036A Single Cylinder Deadbolt Lever Lockset is the nearest cross-brand match. Like the 8070 Belmont, it is a solid brass single cylinder lockset, so one side takes a key and the other operates without one. The 8070 Belmont carries a 3-5/8 inch center-to-center dimension between the sideplate bore centers and is a tubular lock in brass; the Omnia is described as a deadbolt lever lockset in solid brass construction. Confirm the center-to-center spacing on the door being retrofitted before choosing between them, because the two do not share a bore spacing.

3-5/8 inches is the distance between the two mounting points on the sideplate, which fixes how tall the plate footprint is on the door face. It matters when you are replacing an older sideplate set or matching an adjacent opening, because a plate with a different center-to-center will leave holes exposed or land on fresh wood.

Any Emtek brass knob or lever style pairs with it, and the inside trim choice is a required selection covering the full brass range, from levers like Stuttgart, Athena, Luzern and Milano to knobs like Ace, Orb, Round, Belmont and the crystal knobs such as Bristol and Windsor. Pick the trim to match the rest of the openings in the house; the lock body and prep do not change with the style.

No. The 8070 Belmont is a residential tubular lockset in brass, aimed at houses and residential units. For a commercial entrance with traffic and code requirements, you want a cylindrical or mortise lockset built for that duty rather than this set.

The Omnia D12036PD is a solid brass dummy deadbolt lever lockset with plates at 5-1/2 inch center to center, a double dummy function, meaning both levers are fixed trim with no latch and no cylinder. That suits an inactive leaf of a pair or a closet door pulled shut against a stop. The Emtek 8070 Belmont is a keyed entry lockset with a latch and strike plate included, so it is the choice only where the door has to latch and lock.

No. The D12036PD carries a 5-1/2 inch center to center between plate bores, while the 8070 Belmont is a 3-5/8 inch center-to-center set, so the sideplate holes do not line up. Beyond the spacing, the Omnia is a double dummy with no latch to fill the cross bore, and the Belmont set is a keyed entry lock working a latch through a 2-1/8 inch cross bore. Measure the existing bore spacing on the door before ordering either one.

Both are solid brass single cylinder sideplate lever locksets. The 8070 Belmont is ordered as a complete set with knob or lever, latch and strike plate, and the buyer specifies handing, backset at 2-3/8 or 2-3/4 inch, finish, and the inside knob or lever style, with the set fitting doors 1-3/8 to 1-3/4 inch thick and marked for residential use. The Omnia D12036A is catalogued as a single cylinder solid brass deadbolt lever lockset. Match the choice to the bore spacing already in the door and to the trim style the rest of the openings carry.
