Delaney Hardware D12322 – Frequently Asked Questions
1) What door prep does the Belton knobset need, and will it drop into an existing bore?
It uses the standard residential prep: 2-1/8 inch cross bore and a 1 inch edge bore. If the door already has that prep from a previous knob, the Belton goes straight in. The latch faceplate is 1 x 2.25 inch with round corners, so an existing round-corner mortise in the door edge should match up.
2) Will the Belton privacy knob latch into the strike plate already in my door frame?
The latch has a 1/2 inch throw and ships with a 2-1/4 inch T-strike. If your frame currently has a full-lip or square-corner strike, the T-strike prep won't line up and you'll want to swap the strike rather than reuse the old one.
3) Is a Grade 3 privacy knob enough for apartment bedrooms and bathrooms?
Grade 3 is the residential duty level, and Delaney lists the Belton as a residential product. For bedroom and bath doors in apartments or single-family rentals it is the normal choice. For a commercial corridor, a school, or anything seeing heavy public traffic, step up to a Grade 2 or Grade 1 cylindrical lock such as the Dexter C2000 privacy knob (Grade 2) instead.
4) How does the Belton privacy lock get opened from the outside in an emergency?
It locks from the inside by pressing the button in the knob. From the hallway side there is an emergency release that unlocks it, which is what you need for a bathroom or a child's bedroom. From inside, simply turning the knob releases the button, so nobody can be trapped behind it.
5) What backset does the Belton privacy knobset use?
It is set up for a 2-3/4 inch backset, the deeper of the two standard bored-lock backsets. Measure from the door edge to the center of the 2-1/8 inch bore before ordering; if your doors are bored at 2-3/8 inches, this one will not line up.
6) What is the closest Grade 3 privacy knob equivalent to the Delaney Belton privacy knobset?
The Delaney Belton privacy knobset is a Grade 3 cylindrical privacy/bed/bath knob. Two Grade 3 privacy knobs match that same function and grade: the Cal-Royal BER20 privacy knob lock with brass trim, rated for 1-3/8 inch to 1-3/4 inch doors, and the Pamex FTF Baron privacy knob lockset, also Grade 3 and rated 1-3/8 inch to 1-3/4 inch. The Belton itself covers a standard door thickness of 1-3/8 inch to 2 inch, so on doors thicker than 1-3/4 inch the Belton is the one that still fits.
7) I need a privacy knob for a commercial bathroom with heavy traffic - is the Delaney Belton the right choice or should I step up?
The Delaney Belton privacy knobset is a Grade 3 knob listed for residential use. For a higher-duty privacy knob, the Dexter C2000 Series privacy cylindrical ball knob is Grade 2, non-clutching and non-keyed, fitting doors 1-3/8 inch to 1-3/4 inch. Grade 2 is the higher ANSI/BHMA cycle and strength tier, so on a high-traffic restroom the C2000 privacy knob is the heavier option, while the Belton covers residential bed and bath openings and doors up to 2 inch thick.
8) I am standardizing a whole building on one knob family - can I match the Delaney Belton privacy across every function?
The Belton privacy knobset covers the bed and bath openings only. If a single family across privacy, passage and keyed openings matters, the Pamex FTF Baron line runs Grade 3 in privacy, passage and entrance/office, all for 1-3/8 inch to 1-3/4 inch doors. The Dexter C2000 Series does the same one grade up at Grade 2, with privacy, passage, entry/office and classroom knobs for the same thickness range. The Belton is the choice where doors run up to 2 inch and a round commercial-appearance knob with concealed mounting screws is wanted.
9) What finishes does the Delaney Belton privacy knob come in for matching other doors in a building?
Three finishes: US32D stainless steel, US12P Tuscany bronze, and US19 black. US32D is the usual match for satin stainless or satin chrome hardware already in a building; US19 black suits matte black packages. Pick one finish and standardize the whole floor on it, since the Belton round knob has a plain commercial look that blends with most existing trim.
10) I need passage and entry knobs to match these privacy knobs. What are my options?
The Belton privacy knob is the bed and bath function only, with no key. For matching hall and closet doors you need a passage set, and for exterior or office doors a keyed entrance set. Grade 3 options in the same class include the Pamex FTF Baron series, which comes in privacy, passage, and entrance/office functions, and the Cal-Royal BER series with entrance/office (BER00) and privacy (BER20) knobs. Those families let you keep one knob style across every function in the unit.
11) What's an alternative to the Belton if my doors are thicker than 2 inches?
The Belton tops out at 2 inch doors. For anything thicker, the Falcon X101 cylindrical knobset covers 1-3/8 inch to 2-1/4 inch doors. Bear in mind that one is a passage function, not privacy, so it has no locking button.
12) The door does not need to lock - what do I order instead of the Delaney Belton privacy knobset?
The Belton is a privacy knob, locked by an inside button with an emergency release outside. For a hall or closet door that only needs a latch, the passage equivalents include the Pamex FTF Baron Grade 3 passage knob lockset for 1-3/8 inch to 1-3/4 inch doors, the Arrow MK01 Grade 2 non-keyed passage knob, and the Kwikset 200P Polo passage knob supplied with a 6AL latch and round corner strike. For a door with no latch at all - a closet or an inactive leaf - the Bravura Biloxi round trim dummy knobset is Grade 2 dummy trim.
13) The opening needs a key, not a privacy button - what replaces the Delaney Belton?
The Belton is non-keyed privacy only. For a keyed opening at the same Grade 3 level, the Cal-Royal BER00 is a Grade 3 entrance/office knob lock with a Kwikset keyway for 1-3/8 inch to 1-3/4 inch doors, and the Pamex FTF Baron entrance/office knob lockset is Grade 3 for the same thickness range. The Kwikset 400P-CP Polo keyed entry knob is also Grade 3 and ships with a round corner adjustable latch and round corner strike.
14) Which privacy knobs look like substitutes for the Delaney Belton but are a different style of product?
Several privacy knobs will show up alongside the Delaney Belton but are decorative rather than commercial-appearance round knobs. The Baldwin Estate 5077 Bethpage privacy knob uses an R027 rose, the Baldwin Estate 5000 Baltimore privacy knob is preconfigured with a 5148 rose, a 2-3/8 inch backset and a full lip strike, and the Deltana 6112 St. Thomas privacy knob fits 1-3/8 inch to 2 inch doors. The Belton uses a 2-1/4 inch T-strike and fits a 2-3/4 inch backset prep, so the Baldwin 5000 privacy set at 2-3/8 inch backset with a full lip strike is not a drop-in for the same door prep.
15) Does the Delaney Belton privacy knobset fit a thicker door than the usual Grade 3 knobs?
Yes. The Delaney Belton privacy knobset is listed for standard door thickness from 1-3/8 inch to 2 inch. Most of the comparable Grade 3 knobs stop at 1-3/4 inch - the Cal-Royal BER20 privacy, the Pamex FTF Baron privacy, and the Pamex FT3 Saturn knob lockset are all 1-3/8 inch to 1-3/4 inch. Among the wider-range options, the Corbin Russwin CK4310 Grade 1 passage knob and the Deltana 6171 round knob entry both cover 1-3/8 inch to 2 inch, though neither is a privacy function.
16) The opening is a fire-rated door - is the Delaney Belton privacy knobset the right pick?
The Delaney Belton is a Grade 3 residential privacy knobset. Where a fire rating is called for on the drawing, the Falcon W101 Grade 2 cylindrical knob lock is a medium duty passage/closet function with a fire rating and a 2-3/4 inch backset, and the Falcon X101 is a heavy duty Grade 1 passage knobset with an interchangeable core, fire rated, for doors 1-3/8 inch to 2-1/4 inch. Both are passage rather than privacy function, so confirm the opening does not need the inside locking button before substituting.
17) Are the mounting screws visible on the Belton knob rose?
No. The Belton uses concealed mounting screws, so the rose faces the room with no exposed fasteners. That is the difference between it and cheaper knobsets that show two screw heads on the inside rose.
18) Is the Sure-Loc Bergen 6-pack an alternative to buying multiple Delaney Belton privacy knobsets?
Not for the same openings. The Sure-Loc Bergen is a round knob sold as a 6-pack with an adjustable backset, which suits builder-quantity buying, but the Delaney Belton is specifically a privacy function with an inside push button and an outside emergency release for bed and bath doors. Match the function first: for privacy openings the Belton, or another privacy-function knob such as the Cal-Royal BER20 Grade 3 privacy knob lock, is what the door needs.
