Emtek STUDIO Brass Knobsets - The Ace Knurled Knob

Yes. The Ace Knurled Knob set works on doors from 1-3/8 inches up to 2-1/4 inches thick with the standard 2-1/8 inch cross bore prep, so a 1-3/4 inch door (the usual commercial thickness) drops straight in. There is a text field for door thickness on the order so you can call out what you have. One exception on prep: the STRETTO rosette needs a 1-1/4 inch diameter bore and a 2-hole door preparation for the thumbturn privacy function.

The standard latch ships for a 2-3/8 inch backset. If your existing bore is 2-3/4 inches from the door edge to the center of the hole, you have to specify 2-3/4 inch backset when you order, it is a required selection. Measure from the edge of the door to the center of the 2-1/8 inch cross bore before you pick. Those are the two backsets used on residential and light commercial doors, so one of them will match.

It is sold as a complete set: both knobs, the latch, the strike plate, and the dust box. Nothing else is needed for a standard bored door. Two things are extras: the 28 degree latch is an added charge, and if you want a pair of knobs on a door with no latch at all you order the Dummy, Pair function instead.

Bathroom and bedroom doors take the Privacy Set, which locks from the inside. Hall, closet, and pantry doors take the Passage Set, which just latches and never locks. Both come in a Standard version and a CF Mechanism version. For a closet with double doors or a door that only needs a pull, order Dummy, Pair, which has no latch at all. There is no keyed entry function in the Ace knurled knob range, so a front door needs a different lock.

Handing is a required selection, right hand or left hand. Stand outside the door: if the hinges are on your right it is right hand, hinges on the left is left hand. Get it wrong and the knurl pattern and rosette orientation sit the wrong way relative to the door swing. Backset is also required, and door thickness is an optional note you can add to the order.

It is a residential tubular knob set in solid brass, so it belongs on interior doors in homes, condos, and apartment units. For corridor, classroom, office, or other commercial openings that need a graded cylindrical lock, look at something like the Schlage D10S Grade 1 passage knob or the Corbin Russwin CK4310 Grade 1 passage lock instead. A property manager doing unit interiors can use the Ace; the same manager doing common-area doors should not.

No. The Ace Knurled Knob is offered in passage, privacy, and dummy only, with no keyed cylinder function, so it will not secure an exterior or storeroom door. For keyed entry in a knob, the Kwikset 400P-CP Polo keyed entry (Grade 3, 1-3/8 to 1-3/4 inch doors) suits residential, and the BEST 8K Series Grade 1 entrance knob or the Sargent 8XG04 Grade 1 storeroom knob with 2-3/4 inch backset suit commercial openings.

In most cases yes. It uses the standard bored door prep, a 2-1/8 inch cross bore with a 2-3/8 or 2-3/4 inch backset, which is the same prep under a Kwikset Polo or a Schlage F Series residential knob. As long as the existing bore is 2-1/8 inches and the door is between 1-3/8 and 2-1/4 inches thick, the Ace goes in the same holes. The one prep change to watch is a privacy set with the STRETTO rosette, which needs a 1-1/4 inch bore and a second hole for the thumbturn.

The Ace Knurled Knob is a brass knobset sold as a complete set with latch, strike plate, and dust box, in passage, privacy, and dummy functions. The nearest solid brass decorative peers are the Omnia 434/PA egg-shaped knob latchset in passage function with a 3 inch projection, the Omnia 434/0 egg-shaped single dummy lockset, and the Baldwin Estate 5011 Colonial passage knob with 5058 rose. The difference is the knob face and rose: the Ace is a knurled knob that can be ordered on Disk, Modern Rectangular, Quincy, Square, Urban Modern, Watford, or Wilshire rosettes, while the Omnia and Baldwin knobs are smooth traditional shapes on their own fixed roses.

The Ace Knurled Knob is a residential brass knobset in passage, privacy, and dummy functions. For an opening that needs a commercial cylindrical knob lock, the Schlage D10S is a Grade 1 heavy duty passage knob lock with an Orbit knob, and the Falcon X101 is a Grade 1 heavy duty cylindrical passage knobset with an interchangeable core that fits doors 1-3/8 inch to 2-1/4 inch thick. Both are plain commercial knob designs rather than a knurled decorative knob on a choice of brass rosette.

The Ace Knurled Knob is offered in dummy, passage, and privacy functions only, so a keyed opening needs a different lock. For a residential keyed entry knob, the Kwikset 400P-CP is a Grade 3 keyed entry Polo knob for doors 1-3/8 inch to 1-3/4 inch thick with a round corner adjustable latch and round corner strike, and the Master Lock BC01 is a Grade 3 keyed entry Biscuit knob. On the decorative brass side, the Deltana 6901 Portland Knob is an entry function knob for doors 1-3/8 inch to 1-3/4 inch, and the Deltana 3381 Egg Knob entry covers 1-3/8 inch to 2 inch.

Several knob products in the same family are trim only, not complete bored locksets. The Sargent 28C-KNOB is exit device trim with knob and rose 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 from the ED-500 Series. Those mount to an exit device, not into a 2-1/8 inch cross bore. The Ace Knurled Knob is a complete set including latch, strike plate, and dust box that fits a 2-1/8 inch bore standard door prep.

The Ace Knurled Knob fits doors from 1-3/8 inch to 2-1/4 inch thick with a 2-1/8 inch bore. If you want a peer that also reaches past 1-3/4 inch, the Falcon X101 Grade 1 passage knobset covers 1-3/8 inch to 2-1/4 inch, the Corbin Russwin CK4310 Grade 1 passage/closet lock covers 1-3/8 inch to 2 inch, and the Deltana 6171 Round Knob entry covers 1-3/8 inch to 2 inch. The Corbin Russwin CK4410 Grade 2 passage lock stops at 1-3/4 inch, so it is not a fit for the thicker leaf.

The Ace Knurled Knob does not cover keyed institutional functions; it is offered in dummy, passage, and privacy. For storeroom, the Sargent 8XG04 is a Grade 1 heavy duty single cylinder storeroom/closet knob lock with a 2-3/4 inch backset, and the Sargent 6G04 is a Grade 2 standard duty storeroom/closet knob lock with a single cylinder. For classroom, the Dexter C2000 Series offers a Grade 2 classroom ball knob lock, keyed and non-clutching, for doors 1-3/8 inch to 1-3/4 inch.

Yes, the Ace Knurled Knob can be ordered with any brass rosette. The choices are Disk, Modern Rectangular, Quincy, Square, Urban Modern, Watford, and Wilshire, so you can run a round Disk rose in one part of a house and a Modern Rectangular in another with the same knob on both. If you go with the STRETTO rosette for a privacy set, note the different bore: 1-1/4 inch diameter with a 2-hole prep.

Yes. There is an optional split finish field on the order where you specify the two finishes. Ten finishes are offered: Flat Black (US19), French Antique (US7), Matte White (MW), Pewter (US15A), Polished Chrome (US26), Polished Nickel Lifetime (US14), Satin Brass (US4), Satin Nickel (US15), Satin Rose Gold (SRG), and Unlacquered Brass (US3NL). Unlacquered brass is the one that will patina over time rather than hold its as-shipped look.

For the same decorative, solid-brass residential look, the Baldwin Estate 5011 Colonial passage knob with 5058 rose and the Omnia 434/PA egg-shaped knob latchset are the close cousins. If you want a plainer, lower-cost interior knob, the Pamex FTF Baron Grade 3 passage and the Cal-Royal BA40 dummy cover the basics on 1-3/8 to 1-3/4 inch doors. What none of those give you is the knurled grip texture and the seven-rosette mix-and-match the Ace has.

For interior passage and privacy doors, several graded knob locks cover the same functions at plainer trim. The Dexter C2000 Series offers Grade 2 passage and Grade 2 privacy ball knob locks for doors 1-3/8 inch to 1-3/4 inch. The Pamex FTF Baron is Grade 3 in passage and privacy for the same thickness range. The Ace Knurled Knob differs in that it is a brass residential set with a knurled knob face and a choice of finishes including Flat Black (US19), Matte White (MW), Satin Rose Gold (SRG), and Unlacquered Brass (US3NL), where the Dexter and Pamex sets are plain ball and Baron knob designs.

The Ace Knurled Knob is sold as a complete set including latch, strike plate, and dust box, with a standard latch for 2-3/8 inch backset and 2-3/4 inch available. Comparable complete-set peers include the Baldwin Estate 5000 Baltimore passage knob with 5048 rose, supplied with a 2-3/8 inch backset and full lip strike, the Baldwin Estate 5000 Baltimore privacy knob with 5148 rose and full lip strike, the Kwikset 200P Polo passage knob with a 6AL latch and RCS round corner strike, and the Schlage Residential F500 Plymouth with Georgian knob combo pack with adjustable backsets and dual strikes.

They solve different problems. The Lockey 3830 is a mechanical keyless combination knob lock with an auto-locking passage function for doors 1 3/16 inch to 2 inch thick, so entry is by code. The Ace Knurled Knob is a non-electronic brass knobset in passage, privacy, and dummy functions with no code or key credential. If access control is the requirement, the Lockey covers it; if the requirement is a knurled brass knob on a matching rosette, it does not.

For a straightforward Grade 2 passage knob, the Arrow MK01 and Arrow RK01 are non-keyed Grade 2 passage cylindrical knob locks for doors 1-3/8 inch to 1-3/4 inch, the RK01 with a ball knob. The Bravura Albany and Bravura Lynchburg are Grade 2 passage knobsets with round trim, and the Bravura Dallas is a Grade 2 passage knobset with rectangle trim in US4 Satin Brass. The Ace Knurled Knob also offers Satin Brass (US4) among its finishes, so it is the matching option if the knurled brass look is what the job wants.

The 28 degree latch is an alternate latch available at additional charge on the Ace Knurled Knob set. The standard latch is included in the set along with the strike plate and dust box, so you only add the 28 degree latch when your opening calls for it. It is an order-line option, not something you retrofit later, so specify it up front.
