Emtek STUDIO Brass Knobsets - The Ace Knob

Yes. The Ace knobset drops into a standard 2-1/8 inch cross bore prep and covers doors from 1-3/8 inch up to 2-1/4 inch thick, so a typical 1-3/4 inch residential or interior door needs no extra prep. The one exception is the STRETTO rosette, which wants a 1-1/4 inch diameter bore and a 2-hole prep for the privacy thumbturn.

It ships as a complete set: both knobs with rosettes, the latch, the strike plate, and the dust box. Nothing else is needed for a standard bored door. A 28 degree latch is offered at additional cost if your door or frame calls for it.

Five functions are offered: Privacy Set in standard or CF mechanism for bedrooms and baths, Passage Set in standard or CF mechanism for halls, closets and other doors that need no lock, and Dummy Pair for a non-operating door such as a closet or a pantry with a ball catch. There is no keyed entry function on the Ace, so an exterior entry door needs a different lock.

Handing is a required choice, right hand or left hand. Stand outside the door (the side it swings away from): if the hinges are on your right, it's right hand. Getting it wrong on a privacy set puts the thumbturn on the wrong face of the door.

No. Emtek classes the Studio Brass line as residential, and the Ace is a tubular knobset in solid brass with no ANSI grade behind it. For a corridor, office or any opening with real traffic, use a graded cylindrical lock instead: the Schlage D Series D10S passage knob and the Corbin Russwin CK4310 are Grade 1 heavy duty options, and the Falcon W101 is Grade 2 medium duty. The Ace belongs on interior residential doors, custom homes and high end multi-family unit interiors.

In most cases yes on the prep. The Ace uses the same 2-1/8 inch cross bore and 2-3/8 or 2-3/4 inch backset as standard residential knobs like the Kwikset 200P Polo passage and the Schlage Residential F500 Plymouth with Georgian knob, which covers 1-3/8 to 1-3/4 inch doors. What will not carry over is keying: the Ace is offered in passage, privacy and dummy only, so it cannot replace a keyed entry knob such as the Kwikset 400P.

The Emtek STUDIO Brass Ace knob is a residential tubular knobset in brass, so when a spec calls for a graded cylindrical knob the substitution moves to a commercial line. The Schlage D10S is a Grade 1 passage cylindrical non-keyed knob lock with an Orbit knob in the D Series, and the Corbin Russwin CK4310 is a Grade 1 passage/closet cylindrical lock with a Global knob covering 1-3/8 inch to 2 inch doors. Both carry a stated grade the Ace does not, and both use a plain functional knob design rather than a decorative brass rosette.

The Ace knob is offered in dummy, passage and privacy functions only, so a keyed opening needs a different lockset. For residential work the Kwikset 400P Polo is an entry knob lock supplied with a 6AL latch and RCS strike, and the Kwikset 400P-CP is a Grade 3 keyed entry knob for 1-3/8 to 1-3/4 inch doors with a round corner adjustable latch. On the decorative side, the Deltana 6171 Round Knob and Deltana 3381 Egg Knob are entry-function knobs covering 1-3/8 inch to 2 inch doors.

The Emtek Ace knobset is specified for doors 1-3/8 inch to 1-3/4 inch thick with a 2-1/8 inch cross bore. For thicker stock, the Corbin Russwin CK4310 Grade 1 passage lock and the CK4851 Grade 1 entrance/office lock both cover 1-3/8 inch to 2 inch, the Deltana 6112 St. Thomas privacy knob covers 1-3/8 inch to 2 inch, and the Falcon X101 Grade 1 passage knobset with interchangeable core reaches 1-3/8 inch to 2-1/4 inch.

The Ace is a residential brass knobset. Where a fire rating is called for, the Falcon W101 is a Grade 2 medium duty cylindrical knob lock in passage/closet function with a 2-3/4 inch backset and a stated fire rating, and the Falcon X101 is a heavy duty Grade 1 passage knobset with interchangeable core, also fire rated, for doors 1-3/8 inch to 2-1/4 inch.

The Ace knob can be ordered with any brass rosette, and seven shapes are offered: Disk, Modern Rectangular, Quincy, Square, Urban Modern, Watford and Wilshire. Ten finishes are available, from Flat Black (US19) and Pewter (US15A) through Polished Chrome (US26), Polished Nickel Lifetime (US14), Satin Brass (US4), Satin Nickel (US15), Satin Rose Gold (SRG), French Antique (US7), Matte White (MW) and Unlacquered Brass (US3NL). A split finish option is available at order time if you want the inside face different from the outside, which is a common ask when a hallway and a bedroom are painted differently.

For the same decorative solid brass interior category, the Baldwin Estate 5077 Bethpage privacy knob with the R027 rose and the Deltana 6112 St. Thomas privacy knob are the closest peers, and the Deltana covers 1-3/8 to 2 inch doors. If you want traditional egg shaped rather than the Ace's contemporary look, the Omnia 434/PA passage latchset is solid brass as well. All of these are decorative residential lines, not graded commercial hardware.

Yes, up to 2-1/4 inches. Thick doors are common on custom interiors and on solid core slabs, and the Ace covers 1-3/8 inch through 2-1/4 inch. Door Thickness is a text field at order time, so state the actual measured thickness of your slab when you place the order rather than assuming standard. Among comparable knobs, the Deltana 3381 and 6171 go to 2 inches and the Falcon X101 to 2-1/4 inches.

The Emtek Ace is a brass knobset built around a choice of seven rosettes including Disk, Square, Quincy and Wilshire. If a single fixed trim is acceptable, the Omnia 434/PA is a traditional egg-shaped knob latchset in solid brass with a 3 inch projection in passage/hall/closet function, and the Baldwin Estate 5011 Colonial passage knob comes with the 5058 rose. Both arrive as one configured design rather than a knob-plus-rosette selection.

The Ace is available in privacy function in standard and CF mechanism versions. Where a plainer privacy knob suits the unit, the Dexter C2000 is a Grade 2 privacy cylindrical ball knob for 1-3/8 to 1-3/4 inch doors, the Cal-Royal BER20 is a Grade 3 privacy knob lock with brass trim over the same thickness range, and the Pamex FTF is a Grade 3 Baron knob privacy lockset also for 1-3/8 to 1-3/4 inch doors. For a decorative privacy knob, the Baldwin Estate 5077 Bethpage uses the R027 rose.

The Ace dummy is sold as a pair, which covers both faces of a single door or one leaf of a set. Single dummy trims cover one face only: the BEST 6K Series is a Grade 2 medium duty single dummy trim, the Schlage A170 is a Grade 2 heavy duty single dummy trim for 1-3/8 to 1-7/8 inch doors, the Omnia 458/0 is a single dummy knob latchset with a 2-3/8 inch backset in solid brass, and the Omnia 442/00 is a single dummy latchset with a 2-5/8 inch rose. Ordering a single dummy where a pair is needed leaves one face bare.

Several knob products in the same family are exit device trim rather than a complete bored lockset for a door prep. The Sargent 28C-KNOB is exit device trim with knob and rose in entrance function for 1-3/4 inch doors, the Sargent 78-2875 is an outside knob only with B design, and the Imperial USA ED-BKL580 is knob trim in storeroom function for the ED-500 Series. None of them replace a complete knobset that ships with latch, strike plate and dust box the way the Emtek Ace does.

The Ace covers dummy, passage and privacy on a brass knob with a choice of rosette, and needs the handing and backset called out per opening. A builder-grade line handles the same interior functions from one part family: the Pamex FTF Baron is a Grade 3 knob lockset in entrance/office, privacy and passage versions all for 1-3/8 to 1-3/4 inch doors, and the Dexter C2000 Series covers passage, privacy, entry/office and classroom in Grade 2 over the same thickness range. Mixing means the units carry two different knob profiles and rose diameters.

The Ace does not include a storeroom function. For that opening the Sargent 6G04 is a Grade 2 standard duty storeroom/closet knob lock with a single cylinder, and the Sargent 8XG04 is a Grade 1 heavy duty storeroom/closet single cylinder knob lock with a 2-3/4 inch backset, which matches the wider of the two backsets the Ace latch is offered in.

The Ace knobset is a mechanical, non-electronic tubular lock offered in dummy, passage and privacy. Where the door needs coded access without a key, the Lockey 3830 is a mechanical keyless combination knob lock with auto-locking passage function for doors 1 3/16 inch to 2 inch thick. It is a functional knob rather than a decorative brass set on a selectable rosette.

CF is Emtek's crystal and finish mechanism variant offered alongside the standard on both passage and privacy Ace sets. Both are non-keyed tubular mechanisms in the same 2-1/8 inch bore, so the prep does not change between them. Pick the one that matches the rest of the Emtek hardware already hung in the house so the feel and the trim stack are consistent across openings.

The 28 degree latch is an add on at extra cost and is used where the standard latch face angle does not sit right against the frame, typically on doors with a beveled edge. It is not included by default, so call it out on the order if the door edge is beveled. Everything else in the set, latch, strike plate and dust box, ships standard.

The Ace is a contemporary knob design offered in ten finishes including Flat Black, Satin Brass and Unlacquered Brass. For a plain profile, the Arrow RK01 is a Grade 2 non-keyed passage cylindrical lock with a ball knob for 1-3/8 to 1-3/4 inch doors, the Arrow MK01 is the Grade 2 passage knob lock in the MK Series over the same range, and the Bravura Albany and Lynchburg are Grade 2 passage knobsets with round trim.

The Ace latch ships standard for a 2-3/8 inch backset, with 2-3/4 inch specified at order. Where a single part covering both is easier, the Schlage Residential F500 Plymouth with Georgian knob is a combo pack with adjustable backsets and dual strikes for 1-3/8 to 1-3/4 inch doors, and the Kwikset 200P-CP Polo passage knob ships with a round corner adjustable latch and round corner strike.

Alternatives in dummy function include the Bravura Biloxi, a Grade 2 dummy knobset with round trim, the Cal-Royal BA40 dummy knob cylindrical lock from the Barrington BA Series for 1-3/8 to 1-3/4 inch doors, and the Omnia 434/0 traditional egg-shaped single dummy interior lockset in solid brass. The Emtek Ace dummy is supplied as a pair on a selectable brass rosette.
