Delaney Belton - Grade 3 SIngle Dummy Knob

No latch, no turning action. The Belton single dummy is a knob and rose that screw to the face of the door as a fixed pull. Nothing retracts, so it will not hold a door closed on its own. Use it on a closet or French door leaf that is held by a ball catch or roller catch, or as the trim on an inactive leaf of a pair. Single means one knob, one side of the door. If you need both sides dressed, you are buying two.

Yes. The Belton is built to the standard 2-1/8 inch cross bore, so it mounts over the existing bore from a cylindrical knob and the rose covers it. That is the usual swap when a closet or pantry knob stopped working and nobody wants it to latch anymore. The 2-3/8 or 2-3/4 inch edge bore for the latch just goes unused, since a dummy has no latch in it.

Grade 3 is the residential duty tier, and Delaney lists the Belton as residential. For an apartment interior, a leasing office closet, or a French door leaf, that is fine, because a dummy has no latch or cylinder to wear out and the grade is really describing the rose and knob hardware. For a heavy-traffic commercial corridor where you want a heavier dummy trim, the Schlage A170 single dummy is Grade 2 and rated heavy duty, and the BEST 6K single dummy trim is Grade 2 medium duty.

The Belton knob you are looking at is the single dummy, so it is trim only. If you are standardizing a run of doors where some have to latch, other Grade 3 knobsets that pair sensibly include the Pamex FTF Baron in passage, privacy, and entrance/office, and the Cal-Royal Barrington BER00 entrance/office and BER20 privacy, all of which take the same 1-3/8 to 1-3/4 inch doors. Cal-Royal also makes the BA40 dummy in that Barrington family, so you can get a matched dummy and functioning set from one series.

Single, not a pair. The Belton single dummy is one knob for one face, so a set of French doors where both leaves need a knob takes 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 a pair. Those are decorative brass and crystal rather than the plain round commercial look of the Belton.

A dummy has no latch, so it will not hold anything closed. For a hall or closet door that needs to latch but not lock, you want a passage function: the Pamex FTF Baron passage is the Grade 3 equivalent, and the Dexter C2000 passage ball knob is Grade 2 for 1-3/8 to 1-3/4 inch doors. For a bedroom or bathroom that needs a push-button, that is privacy function, such as the Cal-Royal BER20 or the Pamex FTF privacy, both Grade 3 on the same door thickness range. Keep the dummy for the inactive leaf.

The Schlage A170 is a single dummy trim cylindrical non-keyed knob lock, so it fills the same role as the Belton single dummy - a knob that mounts to the face of a door with no latch behind it. The Schlage A170 is A Series, listed at Grade 2 and heavy duty, with a door thickness range of 1-3/8 inch to 1-7/8 inch, where the Belton is Grade 3 and covers 1-3/8 inch to 1-3/4 inch. Both are dummy function, so either will pair with an active knob on an inactive leaf or a closet door.

The Delaney Belton dummy is a single dummy, meaning one knob for one face of the door. Several peers are sold the other way: the Emtek Arts and Crafts Hammered Egg dummy and the Emtek Classic Brass Crystal Georgetown and Providence dummy knobs are each supplied as a pair, two knobs for both faces. If a closet or inactive leaf needs a knob on each side, a pair covers it in one order; if only the pull side needs trim, the single dummy is the match.

Both. The Belton covers the standard 1-3/8 inch to 1-3/4 inch range, which takes in older interior doors at 1-3/8 and commercial or exterior-weight doors at 1-3/4. Worth noting for a dummy specifically: it fastens to one face rather than through the door, so thickness matters less than it would on a functioning lockset.

Either. The Belton ships with combination screws that take wood or metal door mounting, so the same box works on a wood closet door in an apartment and a hollow metal door in a corridor. No separate fastener pack to specify.

Three: US32D stainless steel, US12P Tuscany bronze, and US19 black. US32D is the one that matches satin stainless levers and knobs already hung on most commercial and multi-family openings, so if you are dressing an inactive leaf next to existing hardware that is normally the match. US12P and US19 are the darker residential looks.

Both are dummy function cylindrical knobs for doors 1-3/8 inch to 1-3/4 inch thick. The Cal-Royal BA40 is the Barrington BA Series dummy knob cylindrical lock; the Delaney Belton is a Grade 3 single dummy with a round knob and a functional commercial appearance, offered in US32D Stainless Steel, US12P Tuscany Bronze and US19 Black. For a plain round knob dummy on a standard door, they answer the same requirement.

It will mount, but it is not the same part. A passage knob such as the Arrow MK01 or Arrow RK01, both Grade 2 non-keyed passage/hall/closet cylindrical knob locks for 1-3/8 inch to 1-3/4 inch doors, carries a working latch that has to be retracted by turning the knob. The Delaney Belton single dummy has no latch at all and is fixed, which is what suits a counterpart knob on an inactive leaf or a door where a latch is not needed.

The Delaney Belton is a round knob with a functional commercial appearance in a Grade 3 single dummy. The Bravura Biloxi with round trim is a Grade 2 dummy knobset, another round-trim dummy option. By contrast the Omnia 434/0 and the Emtek Arts and Crafts dummy are egg-shaped knobs, and the Emtek Georgetown and Providence dummies are crystal knobs - same dummy function, different profile in the hand.

No. The Sargent 78-2875 outside knob only with B design and the Sargent 28C-KNOB exit device trim with knob and rose for 1-3/4 inch doors are trim that mounts to an exit device, and the Imperial USA ED-BKL580 is ED-500 Series knob trim in storeroom function. Those attach to a rim or mortise exit device chassis. The Delaney Belton single dummy is a cylindrical knob that mounts through a 2-1/8 inch cross bore on a standard door with combination screws for wood or metal.

The Falcon W101 is a Grade 2 medium duty cylindrical knob lock in passage/closet latch function with a 2-3/4 inch backset and carries a fire rating, and the Falcon X101 is a Grade 1 heavy duty cylindrical passage knobset with an interchangeable core, also fire rated, for doors 1-3/8 inch to 2-1/4 inch. Both are passage function with a working latch, unlike the Delaney Belton single dummy, which has no latch.

The Belton single dummy is a counterpart to functioning door hardware, so the working doors need latching sets. The Kwikset 400P-CP Polo keyed entry knob is Grade 3 in entrance function for 1-3/8 inch to 1-3/4 inch doors and ships with a round corner adjustable latch and round corner strike; the Kwikset 200P-CP Polo passage knob comes with the same latch and strike. For privacy, the Dexter C2000 Series privacy ball knob is Grade 2 non-keyed for 1-3/8 inch to 1-3/4 inch doors.

The Delaney Belton is Grade 3 and designated residential. Heavy duty Grade 1 knob locks in the same cylindrical family include the Schlage D10S passage latch with an orbit knob, the Sargent 8XG04 storeroom/closet single cylinder knob lock with a 2-3/4 inch backset, and the BEST 8K Series entrance function single cylinder knob lock. Those are latching functions rather than dummy trim, so the dummy openings still need a dummy part.

No handing. A single dummy knob is a round symmetrical knob with nothing inside it, so it mounts on either leaf and either face with the same part. That is one reason dummies get used to standardize across a building, since there is nothing to get backwards on the order. Put it where the pull is wanted.
