Emtek 5109.OR.US19 – Frequently Asked Questions
1) Will the Emtek Orb passage knob fit a 1-3/4 inch door with a standard 2-1/8 inch bore?
Yes. The Orb knob passage set works on doors 1-3/8 to 2-1/4 inches thick with the standard 2-1/8 inch cross bore prep, so a typical 1-3/4 inch interior door takes it with no new boring. The one exception is the STRETTO rosette, which needs a 1-1/4 inch diameter bore and a 2-hole door prep.
2) What backset do I need to specify for an Emtek Orb knobset, 2-3/8 or 2-3/4?
Measure from the door edge to the center of the bore hole. The standard latch ships for a 2-3/8 inch backset, which is what most residential doors are prepped for; if your door measures 2-3/4 inches you have to specify that at order, since backset is a required selection on the Orb knobset.
3) Does a passage knob lock? What is the difference between passage and privacy on an Emtek Orb knob?
Passage means no lock at all. The Orb knob passage set is non-keyed with no thumbturn, so both knobs always turn and the latch just holds the door shut. That is what you want on a hall, closet, or pantry door. For a bedroom or bathroom you need the privacy version with a thumbturn, and for a door that needs a key you need a keyed entry set instead.
4) What comes in the box with the Emtek Orb passage knobset, and do I need to buy anything else?
It ships as a complete set: both knobs, the rosettes, the latch, and the strike plate. Nothing else is required for a standard bored door. You do choose the latch faceplate style, round corner or square corner, to match the existing mortise in your door edge, and if you pick the Concealed Fastener mechanism the 28 degree rotation latch is included with it.
5) Is the Emtek Orb knobset rated for a commercial building or an office corridor?
It is a residential product, solid brass tubular construction in a contemporary style. For a commercial opening, a leasing office, or anything with real traffic, go to a cylindrical Grade 1 or Grade 2 passage knob instead: the Schlage D10S is a Grade 1 heavy duty passage knob, the Falcon X101 is Grade 1 heavy duty with an interchangeable core, and the Corbin Russwin CK4410 is a Grade 2 passage knob for 1-3/8 to 1-3/4 inch doors.
6) Will an Emtek Orb knobset drop into the holes left by an old Kwikset or Schlage knob?
If the door has the standard bored prep, a 2-1/8 inch cross bore with a 2-3/8 or 2-3/4 inch backset and a 1 inch edge bore mortise, the Orb set replaces a builder knob without new boring. Check the door thickness too, since the set covers 1-3/8 up to 2-1/4 inches. Match the latch faceplate to the existing edge mortise, round corner or square corner, and the strike plate is included so you can swap that at the same time.
7) What is the closest equivalent to an Emtek Orb passage knobset from a commercial-grade manufacturer?
The Emtek Orb knobset is a tubular passage set in brass for residential use, non-keyed, fitting doors 1-3/8" to 1-3/4" thick with an adjustable 2-3/8" or 2-3/4" backset. For the same passage function in a graded commercial line, the Schlage D10S is a Grade 1 heavy duty cylindrical passage latch with an Orbit knob, and the Corbin Russwin CK4310 is a Grade 1 passage/closet cylindrical lock with a Global knob covering doors 1-3/8" to 2" thick. Both operate the same way at the door - knob turns freely from both sides, no lock - but they are cylindrical commercial chassis rather than a decorative brass tubular set.
8) What should I use instead of an Emtek Orb passage knob on a bedroom or bathroom door?
A passage set has no locking function at all, so it is wrong for a bed or bath door. For privacy - a push-button or turn lock on the inside - the Deltana 6112 St. Thomas knob is a privacy set for doors 1-3/8" to 2" thick, the Baldwin Estate 5000 Baltimore knob comes preconfigured as a privacy lock with a 2-3/8" backset and full lip strike, and the Dexter C2000 privacy ball knob is a Grade 2 non-keyed privacy lock for doors 1-3/8" to 1-3/4". Use the passage set for halls, closets, and pantry doors where nothing needs to lock.
9) Is an Emtek Orb passage knobset acceptable for a commercial corridor or a school?
The Emtek Orb knobset is classified for residential use and is a decorative brass tubular set. For a facility that specifies ANSI/BHMA grade or fire rating, the Falcon W101 is a Grade 2 medium duty cylindrical passage/closet knob lock with a fire rating and a 2-3/4" backset, and the Falcon X101 is a Grade 1 heavy duty cylindrical passage knobset, also fire rated, covering doors 1-3/8" to 2-1/4". The Sargent 8XG04 Grade 1 storeroom knob lock is the heavy duty option where the opening also has to stay latched and keyed.
10) What looks like a substitute for an Emtek Orb passage knobset but will not work the same?
Dummy knobs are the common mix-up. The Omnia 434/0 egg-shaped knob, the Omnia 458/0 with 2-3/8" backset, the Bravura Biloxi round trim Grade 2 knobset, and the Schlage A170 Grade 2 heavy duty knob are all dummy trim - the knob is fixed and there is no latch to retract, so they are for inactive or closet-face leaves only. The Emtek Orb passage set turns and retracts a latch, and ships as a complete set with latch and strike plate.
11) What passage knob works on a door thicker than 1-3/4 inches?
The Emtek Orb knobset is specified for doors 1-3/8" to 1-3/4" thick with a 2-1/8" cross bore. For a thicker leaf, the Corbin Russwin CK4310 Grade 1 passage/closet knob covers 1-3/8" to 2", and the Falcon X101 Grade 1 heavy duty passage knobset covers 1-3/8" to 2-1/4". The Lockey 3830 keyless combination knob lock, an auto-locking passage function, fits 1 3/16" to 2" where the opening also needs code entry.
12) What is the Emtek concealed fastener (CF) option and should I pay for it?
With the CF mechanism the rosettes mount with no exposed screws on the face of the trim, which is the reason most people choose it on a visible interior door. Selecting CF also brings the 28 degree rotation latch. If you do not need the clean rosette face, choose the standard mounting instead. It is one of three choices on that axis: 28 Degree Rotation Latch, Add Concealed Fastener Mechanism, or No Thanks (Standard).
13) What rosette shapes and finishes can I get the Emtek Orb knob in?
Six rosettes: Disk, Modern, Modern Rectangular, Neos, Square, and Urban Modern. Eight finishes: Flat Black (US19), French Antique (US7), Oil Rubbed Bronze (US10B), Polished Chrome (US26), Polished Nickel Lifetime (US14), Satin Brass (US4), Satin Nickel (US15), and Unlacquered Brass (US3NL). The Orb knob can be ordered with any brass rosette, and a split finish can be specified if you want the two sides of the door different.
14) I need a decorative brass passage knob but not Emtek. What else is comparable?
Baldwin Estate is the closest in character: the 5011 Colonial passage knob with the 5058 rose, or the preconfigured 5000 Baltimore knob with 5048 rose, which ships with a 2-3/8 inch backset and a full lip strike. Omnia's 434/PA egg-shaped knob latchset is solid brass as well. The difference from the Orb set is styling and how much you configure: the Emtek is contemporary and built to order across rosette, finish, and backset, while the preconfigured Baldwin 5000 comes fixed.
15) Is the Emtek Orb passage knob handed? Can I use it on a left hand and a right hand door?
No handing to specify. The Orb passage set is a non-keyed tubular knob with the same knob both sides, so it goes on either swing. The two things that do have to match your opening are the backset, 2-3/8 or 2-3/4 inches, and the latch faceplate corner, round or square.
16) Can I match Emtek Orb passage knobs to the privacy and keyed doors in the same house?
Yes. The Orb knob is one design in Emtek's brass collection and the passage version shares the same rosette shapes and finishes as the other functions, so a hallway on passage, a bath on privacy, and an entry can all carry the same knob and rosette. Specify the same rosette and the same finish code across the order, and note the split finish field if any door needs different finishes inside and out.
17) What is a simpler passage knob than the Emtek Orb for a rental turn or a spec-grade job?
The Emtek Orb is a configurable brass set - eight finishes from Flat Black (US19) to Unlacquered Brass (US3NL), six rosette shapes, and an optional concealed fastener mechanism so the rosettes carry no exposed screws. Where that configurability is not needed, the Kwikset 200P Polo passage knob ships as a hall/closet lock with a 6AL latch and RCS round corner strike, the Pamex FTF is a Grade 3 Baron knob passage lockset for doors 1-3/8" to 1-3/4", and the Bravura Albany round trim passage knobset is Grade 2. Each is a single fixed configuration rather than a built-to-order set.
18) I need a keyed knob to match Emtek Orb passage sets on the other doors - what pairs with it?
The Emtek Orb knobset is non-keyed, so a keyed opening on the same run needs a different set. Keyed knob options include the Corbin Russwin CK4851 entrance/office cylindrical lock with a conventional cylinder for doors 1-3/8" to 2", the Dexter C2000 Grade 2 entry/office ball knob for doors 1-3/8" to 1-3/4", and the Kwikset 400P-CP Polo keyed entry knob, Grade 3, with a round corner adjustable latch and round corner strike. These are separate product families, so plan the keyed doors on their own hardware rather than expecting a keyed version of the Orb.
19) Emtek Orb passage versus Arrow MK01 - what is the difference?
The Arrow MK01 is a Grade 2 cylindrical passage/hall/closet knob lock for doors 1-3/8" to 1-3/4", and the companion Arrow RK01 is the same Grade 2 passage function with a ball knob. The Emtek Orb covers the same 1-3/8" to 1-3/4" thickness and the same non-locking passage function, but is a brass set built to order across finish and rosette, with an adjustable 2-3/8" or 2-3/4" backset. The Arrow sets carry an ANSI/BHMA grade; the Emtek is the decorative residential route.
20) Can I use an Emtek Orb passage knob on a classroom or storeroom door?
A passage knob latches but never locks, so it does not cover a classroom or storeroom opening. For those, the Sargent 6G04 is a Grade 2 storeroom/closet knob lock with a single cylinder, the Sargent 8XG04 is the Grade 1 heavy duty storeroom version with a 2-3/4" backset, and the Dexter C2000 classroom ball knob is a Grade 2 keyed classroom lock for doors 1-3/8" to 1-3/4". Keep the Emtek Orb for the corridor and closet doors on the same job.
21) Is there a passage knob that comes packaged with both backsets and both strikes instead of specifying one?
The Emtek Orb requires the backset to be chosen at order - 2-3/8" or 2-3/4" - and the latch faceplate comes round or square corner. If the backset is not known at the counter, the Schlage Residential F500 Plymouth with Georgian knob is a combo pack with adjustable backsets and dual strikes for doors 1-3/8" to 1-3/4", and the Kwikset 200P-CP Polo passage knob ships with a round corner adjustable latch and round corner strike. Those settle the prep on site rather than in the order.
22) Is unlacquered brass going to tarnish, and how is it different from the satin brass Orb knob?
Unlacquered Brass (US3NL) is raw brass with no clear coat, so it darkens and patinas with handling, which is the point for many people. Satin Brass (US4) is a finished brass that stays as delivered. Both are on solid brass substrate. If you are outfitting a rental or want every door to look identical for years, pick US4 or a plated finish like Satin Nickel (US15) or Polished Chrome (US26) instead.
23) What is the difference between the Emtek Orb passage set and the Corbin Russwin CK4410?
The Corbin Russwin CK4410 is a Grade 2 passage/closet cylindrical lock with a Global knob for doors 1-3/8" to 1-3/4", while the CK4310 is the Grade 1 version of the same passage function covering 1-3/8" to 2". The Emtek Orb matches the CK4410 on door thickness range and on the non-keyed passage function, and differs in being a brass set offered in eight finishes and six rosette shapes with an optional concealed fastener mechanism.
