Yale Residential YR80DM-605 – Frequently Asked Questions

1) Does the Yale YH Collection Dartmouth single dummy knob have a latch, or is it just a pull?
No latch and no lock. The Dartmouth single dummy is a surface-mounted knob for interior doors that only need a push/pull, like a closet door or one leaf of a French pair that is held shut by a catch or a ball catch you supply separately. It is non-keyed and it does not operate anything inside the door.
2) Will a Yale Dartmouth dummy knob cover the 2-1/8 inch bore left by the knob I am taking off?
Yes. The Dartmouth dummy is specified to a 2-1/8 inch cross bore and a 1 inch edge bore, the standard cylindrical prep, so it lands over an existing knob hole without patching the door. It mounts to the face of the door rather than through a latch case, so the edge bore stays empty once the old latch comes out.
3) What door thickness does the Yale YH Dartmouth knob fit?
1-3/8 to 1-3/4 inches, which covers both the common older interior door and the standard commercial 1-3/4 inch leaf. Anything thicker than 1-3/4 is outside the range.
4) I need both sides of a closet door to have knobs. Is one Dartmouth dummy enough?
One is not enough. The Dartmouth single dummy ships with one knob, one rose, a strike plate and two screws, so it dresses a single face. For a pair of doors or a two-sided closet, order two. If you would rather buy the pair in one box, the Emtek Arts and Crafts Hammered Egg dummy and the Emtek Classic Brass Crystal Georgetown and Providence dummies are all sold as dummy pairs.
5) I have a bedroom door that needs to lock. Can I use a dummy knob there?
No, and this is the most common wrong order on dummy trim. A dummy has no latch, so it will not hold a door closed or give any privacy. For a bedroom or bath you want a privacy knob such as the Dexter C2000 Grade 2 privacy knob (1-3/8 to 1-3/4 inch doors) or the Cal-Royal BER20 Grade 3 privacy knob. For a hall or closet door that has to latch but not lock, a passage knob like the Corbin Russwin CK4410 Grade 2 or the Arrow MK01 is the right part.
6) Which knob products look like a substitute for a Dartmouth dummy but are not?
Trim-only parts are the trap. 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 for the ED-500 exit device series. Those mount to an exit device or a lock chassis, not to a bare door face. The Dartmouth YR80DM is a surface mounted knob with round rose that fits a standard 2-1/8 inch cross bore and 1 inch edge bore.
7) What is the closest equivalent to the Yale YH Collection Dartmouth single dummy knob from another brand?
The Schlage A170 is the nearest match: it is a single dummy trim in a Grade 2 cylindrical non-keyed knob, the same function class as the Dartmouth YR80DM, which is a Grade 2 non-keyed dummy knob. The Schlage A170 covers doors 1-3/8 inch to 1-7/8 inch, while the Dartmouth covers 1-3/8 inch to 1-3/4 inch, so on a 1-7/8 inch door the A170 is the one that fits. BEST 6K Series single dummy trim is also a Grade 2 non-keyed dummy knob if you are standardizing on BEST.
8) The door needs a working latch, not a dummy knob - what should I order instead?
A dummy knob like the Dartmouth YR80DM has no latch, so it will not hold a door closed. For a latching interior door in the same Grade 2 non-keyed class, the Corbin Russwin CK4410 is a Grade 2 passage/closet cylindrical knob for 1-3/8 inch to 1-3/4 inch doors, the Dexter C2000 passage ball knob is Grade 2 for the same thickness range, and the Falcon W101 is a Grade 2 medium duty passage/closet knob that carries a fire rating. Arrow MK01 and RK01 are also Grade 2 non-keyed passage knobs for 1-3/8 inch to 1-3/4 inch doors.
9) The door is thicker than 1-3/4 inches - what knob should I use instead of the Dartmouth?
The Dartmouth YR80DM is built for doors 1-3/8 inch to 1-3/4 inch. On a thicker door, Deltana lists the 3381 Egg Knob entry, 6171 Round Knob entry and 6112 St. Thomas privacy knob at 1-3/8 inch to 2 inch, Corbin Russwin CK4851 entrance/office covers 1-3/8 inch to 2 inch, and Falcon X101 reaches 1-3/8 inch to 2-1/4 inch.
10) Which dummy knob has a fire rating for a rated interior opening?
A dummy knob has no latch and does not latch a rated door. Among knob locks in the set, the Falcon W101 Grade 2 passage/closet knob with a 2-3/4 inch backset and the Falcon X101 Grade 1 heavy duty passage knobset both carry a fire rating. If the opening is rated, one of those latching knobs is the correct part rather than the Dartmouth YR80DM dummy.
11) Is a Yale YH Dartmouth dummy knob durable enough for an apartment building or office corridor?
It carries an ANSI/BHMA A156.2 Grade 2 rating, the light commercial tier, and the catalogue classes it as residential. On a dummy there is no latch to wear out, so the duty question comes down to the finish and the rose staying tight on a door people push all day. If you are standardizing a corridor on heavier trim, the Schlage A170 single dummy is a Grade 2 heavy duty option and the BEST 6K single dummy trim is Grade 2 medium duty.
12) Is there a heavier grade dummy or knob lock than the Yale Dartmouth for a high traffic commercial opening?
The Dartmouth YR80DM is ANSI/BHMA A156.2 Grade 2. For a heavier duty knob on the same style of opening, the BEST 8K Series is a Grade 1 heavy duty entrance knob lock, the Sargent 8XG04 is a Grade 1 heavy duty storeroom/closet knob with a 2-3/4 inch backset, and the Falcon X101 is a Grade 1 heavy duty passage knobset with an interchangeable core covering doors 1-3/8 inch to 2-1/4 inch. Corbin Russwin CK4310 is a Grade 1 passage/closet knob for 1-3/8 inch to 2 inch doors.
13) What is a lower cost dummy knob alternative to the Yale Dartmouth for rental interior doors?
The Bravura Biloxi round trim dummy knobset is a Grade 2 dummy knob, the same grade and function class as the Dartmouth YR80DM, and the Cal-Royal BA40 Barrington is a dummy knob cylindrical lock covering the same 1-3/8 inch to 1-3/4 inch door thickness range the Dartmouth covers. Both give you the push/pull knob without a latch.
14) If a bedroom or bath door needs privacy rather than a dummy knob, what matches the Dartmouth style?
The Dartmouth YR80DM is non-keyed with no lock or latch, so it cannot secure a bathroom. Dexter C2000 privacy ball knob is Grade 2 for 1-3/8 inch to 1-3/4 inch doors, Cal-Royal BER20 is a Grade 3 privacy knob with brass trim for the same range, Pamex FTF Baron is a Grade 3 privacy knob lockset, and Baldwin offers the Estate 5077 Bethpage privacy knob with R027 rose and the Estate 5000 Baltimore privacy knob with a 2-3/8 inch backset and full lip strike.
15) For a keyed entry knob in place of the Dartmouth dummy, what are the options?
The Dartmouth YR80DM is non-keyed, so it takes no cylinder. Keyed knobs in the set include the Cal-Royal BER00 entrance/office Grade 3 with a Kwikset keyway for 1-3/8 inch to 1-3/4 inch doors, the Kwikset 400P-CP Polo keyed entry Grade 3 for the same range, the Dexter C2000 entry/office Grade 2 keyed ball knob, the Master Lock BC01 Grade 3 biscuit knob keyed entry, and the Corbin Russwin CK4851 entrance/office with a conventional cylinder.
16) Are the mounting screws on the Yale Dartmouth dummy visible on the face of the knob?
They are concealed. The rose hides the fasteners, and the screws come pre-installed, so the finished face is clean with no exposed hardware. Installation is a two-screw job through the round rose.
17) How does the Yale Dartmouth dummy compare to the BEST 6K single dummy trim?
Both are Grade 2 non-keyed dummy knobs. The BEST 6K Series single dummy trim is rated medium duty in the 6K Series line. The Yale Dartmouth YR80DM is a round rose design with concealed mounting screws and pre-installed mounting screws, and comes in six finishes including 619 satin nickel, 605 polished brass, 10BP oil rubbed bronze permanent, 613E dark oxidized satin bronze, BSP black suede powder coat and GM gun metal.
