Emtek 7108.BU.FB – Frequently Asked Questions
1) Will the Emtek Butte passage knob fit my existing door prep?
If your door has the standard 2-1/8 inch cross bore, yes. The Butte passage knobset is built for a 2-1/8 inch bore standard prep and fits doors 1-3/8 to 1-3/4 inch thick. One exception: the STRETTO rosette needs a 1-1/4 inch diameter bore and a 2-hole prep, so it is not a drop-in on a plain single-bore door.
2) Do I need to specify a backset when ordering the Butte knobset?
Yes, backset is a required choice. The latch is adjustable for 2-3/8 or 2-3/4 inch backset, and the standard latch ships set for 2-3/8 inch, so call out 2-3/4 inch if that is what your door is bored for. Measure from the door edge to the center of the bore to confirm which you have.
3) Does a passage knob lock? I need this for a bedroom.
No. Passage function means latching only, no locking at all, and the Butte set is non-keyed with no thumbturn. For a bedroom or bath you want a privacy set instead. Halls, closets, and pantries are what passage is for.
4) My door is 2 inches thick. Can I still use this knobset?
Not from the published thickness range. The Butte passage set covers 1-3/8 to 1-3/4 inch doors. For a 2 inch door, the Deltana 6171 Round Knob and Deltana 3381 Egg Knob are listed to 2 inches, and the Falcon X101 passage knobset goes to 2-1/4 inches.
5) For a commercial corridor or classroom door, what passage knob should be used instead of the Emtek Butte?
The Emtek Butte passage knobset is designated residential. For a commercial opening, graded cylindrical passage knobs include the Schlage D10S, a Grade 1 heavy duty non-keyed passage latch with Orbit knob; the Falcon X101, a Grade 1 heavy duty passage knobset that carries a fire rating; and the Corbin Russwin CK4310, a Grade 1 passage/closet knob lock for doors 1-3/8 inch to 2 inch thick.
6) What is a comparable solid brass passage knob if the Emtek Butte sandcast bronze look is not wanted?
The Emtek Butte passage knobset is a non-keyed tubular passage set in a sandcast bronze style, offered in Flat Black Bronze, Medium Bronze and Tumbled White Bronze. For a traditional solid brass alternative in the same passage function, the Omnia 434/PA is an egg-shaped knob latchset with solid brass construction and a 3 inch projection, and the Baldwin Estate 5011 Colonial passage knob comes with the 5058 rose. Both are passage function, so neither locks.
7) The Emtek Butte passage set will not lock a bedroom or bath door - what should be ordered instead?
Correct, the Butte passage set is non-keyed with a passage function, so the knobs always turn. For a bed or bath door needing a thumbturn, the Deltana 6112 St. Thomas privacy knob covers doors 1-3/8 inch to 2 inch, the Baldwin Estate 5077 Bethpage privacy knob uses the R027 rose, and the Cal-Royal BER20 is a Grade 3 privacy knob lock with brass trim. For a keyed exterior door, the Deltana 6901 Portland is an entry knob for 1-3/8 inch to 1-3/4 inch doors.
8) Is there a passage knob for a door thicker than the Emtek Butte range covers?
The Emtek Butte passage set fits doors 1-3/8 inch to 1-3/4 inch in its specifications. For thicker leaves, the Falcon X101 passage knobset covers 1-3/8 inch to 2-1/4 inch, the Corbin Russwin CK4310 passage/closet knob covers 1-3/8 inch to 2 inch, and the Lockey 3830 keyless combination knob with auto-locking passage function covers 1 3/16 inch to 2 inch.
9) What comes in the box with the Emtek Butte passage set?
It ships as a complete set: both knobs, the rosettes you select, the latch, and the strike plate. You choose the latch faceplate corner style, round or square, to match the mortise already cut in your door edge.
10) What is the CF mechanism option on Emtek knobsets and should I pick it?
CF gives you rosettes with no exposed screws, a cleaner face on the door, and it includes the 28 degree rotation latch. The other two choices are the standard latch or the 28 degree latch on its own. The 28 degree latch rotates less to retract, which suits the shorter turn of a sandcast knob.
11) What finishes and rosette shapes can I get the Butte knob in?
Three sandcast bronze finishes: Flat Black Bronze (FB), Medium Bronze (MB), and Tumbled White Bronze (TWB). Rosettes are offered as #1, #2, #3, #4, and #6, and the Butte knob can be ordered with any Sandcast Bronze rosette, so you can match rosette profiles already on other doors in the house.
12) What is a simpler, lower-cost passage knob alternative to the Emtek Butte for closet and hall doors?
The Emtek Butte is a sandcast bronze passage set with five rosette choices and three latch options. If the door only needs a basic hall or closet latch, the Pamex FTF Baron is a Grade 3 passage knob lockset for doors 1-3/8 inch to 1-3/4 inch, the Kwikset 200P Polo passage knob ships with a 6AL latch and round corner strike, and the Dexter C2000 passage is a Grade 2 non-keyed ball knob for the same door thickness range.
13) What passage knob comes ready for a 2-3/4 inch backset without specifying it?
The Emtek Butte passage set is ordered with a 2-3/8 inch or 2-3/4 inch backset selection, with the standard latch supplied for 2-3/8 inch unless 2-3/4 inch is specified. The Falcon W101 is a Grade 2 cylindrical passage/closet knob lock supplied with a 2-3/4 inch backset, and it carries a fire rating. Adjustable-backset alternatives include the Schlage Residential F500 Plymouth with Georgian knob combo pack and the Sure-Loc Bergen round knob 6-pack.
14) If a project needs keyed storeroom or entrance knobs to match passage doors, what pairs with the Emtek Butte function-wise?
The Butte is passage only and non-keyed. Keyed knob functions in the same cylindrical knob format include the Sargent 8XG04 Grade 1 storeroom/closet knob with single cylinder and 2-3/4 inch backset, the Sargent 6G04 Grade 2 storeroom/closet knob, the BEST 8K Grade 1 heavy duty entrance knob with single cylinder, and the Corbin Russwin CK4851 entrance/office knob with a conventional cylinder.
15) What decorative passage knob is closest to the Emtek Butte for a rustic interior?
The Emtek Butte passage knobset is a bronze sandcast design in a rustic style, orderable with any sandcast bronze rosette. Other decorative passage knobs in the same interior-door role are the Baldwin Estate 5000 Baltimore passage knob with 5048 rose, 2-3/8 inch backset and full lip strike, the Bravura Albany and Lynchburg Grade 2 passage knobsets with round trim, and the Bravura Dallas Grade 2 passage knobset with rectangle trim in a US4 satin brass finish.
16) Can I order the Butte knob with different finishes on each side of the door?
Yes, a split finish can be requested when ordering, so an interior face can differ from the hall side. Spell out which finish goes on which side in the comments when you place the order.
