Callan 374004 – Frequently Asked Questions
1) Will the Callan Visconti handleset fit a 1-3/8 inch door, or is it only for 1-3/4?
Both. The Visconti single cylinder handleset covers 1-3/8 inch to 1-3/4 inch doors, so it works on an older interior-weight slab as well as a standard 1-3/4 inch entry door. Backset is adjustable between 2-3/8 and 2-3/4 inches, so it drops onto either of the two common bore layouts without ordering a specific version.
2) Do I have to order a left hand or right hand Callan Visconti handleset?
The handleset itself is fully reversible and works on a left or right hand door either way. Where handing does matter is the interior trim: the order form asks for Left Hand or Right Hand on the inside knob or lever, so stand outside the door and note which side the hinges are on before you order.
3) What do I have to specify when ordering a Callan Visconti handleset?
Five things. Exterior finish (US15 Satin Nickel, US19 Black, or US10BE Edged Bronze), the interior trim (Santo, Canova, or Sorado knob, or the Artino), the handing of that interior trim, the keyway (SC1 5-pin or KW1 5-pin), and the keying (keyed different, keyed alike, or a key charge option). All five are required, so none of them defaults for you.
4) Can I get Callan Visconti handlesets keyed alike so one key runs the whole unit?
Yes. Keyed alike is a selectable option at order time, which is the setup a landlord or property manager wants when the front and side entries on the same unit should take one key. Keyed different is also available if each opening needs its own key. Cylinders are 5 pin, offered in either the SC1 or the KW1 keyway, so pick whichever keyway your building already runs and the new sets can be brought into that system.
5) Is the Callan Visconti handleset strong enough for an apartment or office entry?
It meets BHMA Grade 3 and is built as a residential handleset, with all-metal zinc construction. Grade 3 is the light-duty residential tier, fine for a single-family front door or a low-traffic unit entry. For a commercial entry taking constant daily use, step up: the Bravura 913-Savannah, 915-Jacksonville, and 971-Austin handlesets are Grade 2, as is the Delaney Katana handleset.
6) Will the Callan Visconti latch catch in the strike plate that is already in my frame?
The Visconti ships with a 1/2 inch throw latch and a round corner faceplate. A 1/2 inch throw is the normal residential latch projection, so it will engage a standard strike. The thing to check is the faceplate: if your existing latch has a square corner faceplate, the mortise in the door edge will not match the round corner one, and you will need to square the pocket or swap the strike prep to suit.
7) I only need to add a deadbolt to an entry door, not replace the whole handle. What do I order instead of a handleset?
A handleset like the Callan Visconti is a single cylinder unit that combines the exterior grip and interior trim in one assembly. If the door already has a working knob or lever and the job is only the deadbolt, order a standalone single cylinder deadbolt instead: the Delaney Traditional is a Grade 3 deadbolt with a cylinder x thumbturn function, and the Delaney Contemporary round deadbolt is the same Grade 3 cylinder x thumbturn in a round rose. Both give you the key outside, thumbturn inside arrangement without touching the existing handle.
8) What is the closest equivalent to the Callan Visconti handleset from another brand?
The Delaney Avino is the closest match: it is a Grade 3 single cylinder handleset with interior trim, the same configuration and the same BHMA grade as the Callan Visconti single cylinder handleset with interior trim. Both are exterior entry handlesets keyed on the outside with an interior trim piece, so the Avino drops into the same opening role. If you want the same handleset form in a higher grade, the Delaney Katana is a Grade 2 single cylinder handleset with interior trim.
9) Which handleset should I use if a multi-family entry door needs a higher BHMA grade than Grade 3?
The Callan Visconti handleset meets BHMA Grade 3. When the spec calls for Grade 2 in a handleset of the same single cylinder form, the Delaney Katana single cylinder handleset with interior trim is Grade 2. Bravura also builds Grade 2 handlesets with interior plate and knob: the 913-Savannah with 615 interior plate and 906-Macon knob, the 915-Jacksonville, and the 971-Austin in the same configuration. All four keep the exterior grip plus interior trim arrangement, so the opening prep concept stays the same while the grade rises.
10) Can I use a Schlage F10 Accent or J10 knob in place of the Callan Visconti handleset?
No, those are different functions. The Callan Visconti is a single cylinder keyed entry handleset, keyed on the exterior with a thumbturn inside. The Schlage Residential F10 Accent lever is a passage, hall and closet function lock, and the Schlage Residential J10 Builders Basics knob is a hall and closet passage function. Passage sets have no key and no lock, so neither will secure an entry door. They are the right call for the interior doors on the same job, and both fit 1-3/8 inch to 1-3/4 inch doors, the same door thickness range the Visconti covers.
11) The opening needs credential-based access control rather than a key. What replaces a keyed handleset?
The Callan Visconti is a mechanical single cylinder handleset with a 5 pin KW1 or SC1 cylinder, so access is by cut key only. For card or phone credentials, the Paxton PaxLock Pro Galaxy lever latch lock is a battery powered lever lock with a dual frequency 13.56 MHz and 2.4 GHz reader, Bluetooth, AES128 encryption, UL listing, and a 1-3/4 inch door thickness. That covers openings where an institutional or MRO buyer needs to revoke a credential instead of rekeying a cylinder. Note it is a lever latch lock, not a grip handleset, so the exterior appearance changes.
12) Is a single cylinder handleset the right choice, or do I need a double cylinder for a door with glass?
The Visconti is single cylinder: keyed outside, thumbturn inside. That is the standard choice for a solid entry door and it lets anyone leave without a key. If your door has glass in it or a sidelite within reach of the inside turn, a single cylinder is the one someone can defeat by breaking the glass and reaching through, and many jurisdictions restrict double cylinder on egress doors anyway. Look at the opening before you decide the function.
13) What else does ZenSupply carry that is like the Callan Visconti handleset?
Closest match on grade is the Delaney Avino single cylinder handleset with interior trim, also Grade 3. If you want a heavier lockset in the same handleset format, the Delaney Katana is the Grade 2 version, and Bravura offers four: the 913-Savannah, 915-Jacksonville, and 971-Austin, all with the 906-Macon interior knob, plus the 973-Montgomery which comes with the 939-Charlotte interior lever instead of a knob. The Bravura sets are all Grade 2.
14) Does the Callan Visconti handleset come with the interior knob, or is that a separate part?
The interior trim is included, but you choose it: Santo, Canova, or Sorado knob, or the Artino. The exterior half has a thumb plate grip; the inside is the knob or trim you select. Nothing further is needed to complete the lock.
15) What is the difference between the Bravura handlesets that come with an interior knob versus an interior lever?
Within the Bravura Grade 2 handlesets, the 913-Savannah, 915-Jacksonville, and 971-Austin each pair a 615 interior plate with the 906-Macon interior knob, while the 973-Montgomery pairs a 672 interior plate with the 939-Charlotte interior lever. The Callan Visconti handles the same choice through its interior trim selection, offering the Santo, Canova, and Sorado knobs or the Artino trim, and the interior trim is specified left hand or right hand. Levers are the usual pick where an ADA-conscious facility wants a graspable interior trim; knobs are the traditional residential look.
16) Is an Emtek Select Conical Stem Dark Walnut knob an alternative to the Callan Visconti handleset?
It serves a different opening. The Emtek Select Brass Conical Stem Dark Walnut knob is a passage, hall and closet function, so it has no cylinder and does not lock. The Callan Visconti is a single cylinder keyed entry handleset built for securing an entrance to a residence or place of business. Use the Emtek knob where you want a decorative wood-and-brass interior knob on a non-locking door, and keep the Visconti on the keyed exterior opening.
17) I am standardizing entry hardware across a portfolio of rental units. Which handlesets can I mix and still keep one look and one grade?
The Callan Visconti is a Grade 3 residential single cylinder handleset offered in US15 Satin Nickel, US19 Black, and US10BE Edged Bronze, with keying available keyed different or keyed alike. To stay at Grade 3 across a portfolio while varying the exterior style, the Delaney Avino is also a Grade 3 single cylinder handleset with interior trim. If a subset of doors takes heavier traffic and you want to step those up, the Delaney Katana and the Bravura 973-Montgomery with 672 interior plate and 939-Charlotte interior lever are Grade 2 handlesets. Matching the grade first and the finish family second is how you keep a fleet consistent.
18) Is the Callan Visconti a one-person install or do I need help holding it?
One person. The Visconti is built for a single-installer fit, with the adjustable 2-3/8 to 2-3/4 inch backset latch meaning you are not driving back to the supply house because the door was bored to the other pattern. Standard bit sizes apply: 2-1/8 inch cross bore, 1 inch edge bore.
19) What finishes does the Callan Visconti handleset come in, and will they match my other door hardware?
Three: US15 Satin Nickel, US19 Black, and US10BE Edged Bronze. Those are the standard US finish codes, so US15 will sit alongside other satin nickel hardware and US10BE against oil rubbed and edged bronze trim on the same elevation. Match on the code, not on the marketing name, when you are pairing it to hardware already hung.
