Cal-Royal SSBDK234-US3 – Frequently Asked Questions

1) Will the Cal-Royal SSBDK234 knocker cover the holes left by an IVES 3102 I'm replacing?
The SSBDK234 is similar in profile to the IVES #3102, so it is sold as a direct replacement or upgrade for that knocker. It measures 2-1/8 x 3-3/4 inches with screw holes on 3-1/2 inch centers. Measure the existing hole spacing on the door before you pull the old one off; if the centers match at 3-1/2 inches, the new screws land in the same holes.
2) Is this door knocker rated for a commercial building or is it residential grade?
Cal-Royal classifies the SSBDK234 as commercial, and it conforms to ANSI/BHMA A156.16 L23151, the auxiliary hardware standard that covers this class of door trim. That is the citation a spec writer or institutional buyer needs for office, school, healthcare, retail, government, and multi-tenant residential openings.
3) What is a comparable door knocker to the Cal-Royal SSBDK234 if I need a viewer built into the same plate?
The Cal-Royal SSBDK234 is a solid brass knocker measuring 2-1/8" x 3-3/4" with 3-1/2" CTC screw holes, and it is a knocker only. If the opening needs a knocker and a door viewer in one piece of trim, the Trimco 620 is a contemporary style knocker offered with an optional viewer and optional engraving. That combination lets a single bore serve both the viewer and the knocker on a tenant entry door.
4) Is the Sure-Loc DK180 a direct replacement for the Cal-Royal SSBDK234?
No. The Sure-Loc DK180 is a 5" door knocker intended for residential doors, while the Cal-Royal SSBDK234 is a 2-1/8" x 3-3/4" solid brass knocker classified as commercial and built to ANSI/BHMA A156.16 L23151. The size difference alone means the mounting holes will not line up, and specifications calling for an A156.16 listed knocker will not accept the residential unit.
5) Do I need to buy screws for the Cal-Royal SSBDK234 door knocker, or does it come with them?
Mounting screws are packed with each knocker. Every unit ships individually poly-bagged with the screws included, so there is nothing else to order to hang it. You will still need to drill the door for the 3-1/2 inch center-to-center hole spacing if it isn't already prepped.
6) What finishes does the Cal-Royal SSBDK234 brass door knocker come in?
Three architectural finishes: US3 polished brass, US10B antique bronze oiled, and US15 satin nickel. Those are standard BHMA finish designations, so if your existing entry hardware is already specified in US3, US10B, or US15, the knocker will key into the same finish schedule.
7) Is the Cal-Royal SSBDK234 solid brass all the way through or just brass plated?
Solid brass, not plated over a pot metal core. The substrate is brass and the finish is applied over it, which matters on an exterior entry door where a plated knocker wears through at the strike point. Cal-Royal publishes a finish maintenance and care guide for keeping the finish up in weather-exposed use.
8) What are my other options if the Cal-Royal SSBDK234 is too small for the door?
At 2-1/8 x 3-3/4 inches the SSBDK234 is a compact plate, which reads small on a wide or tall entry slab. For a larger footprint, the Sure-Loc DK180 is a 5 inch knocker for residential doors, and the Emtek 86060 is a 4 inch sandcast bronze knocker with a ring pull. The Emtek 2620 is a solid brass urn-style knocker if you want a more traditional profile in brass.
9) I'm standardizing knockers across a multi-tenant building. Is the Cal-Royal SSBDK234 a good fleet choice?
It works for that. One model number, SSBDK234, three finishes, a fixed 3-1/2 inch CTC hole pattern, and an ANSI/BHMA A156.16 L23151 rating means every door gets the same prep and the same spec line. Because the profile matches the IVES #3102, doors already carrying that knocker convert without redrilling. Screws come in every bag, so your maintenance crew isn't chasing fasteners.
10) I need a traditional colonial look instead of the Cal-Royal SSBDK234 profile - what else should I look at?
The Cal-Royal SSBDK234 is a compact solid brass knocker at 2-1/8" x 3-3/4" with a profile similar to the IVES #3102. For a period entry, the Trimco 621 is a colonial style knocker, and the Emtek 2620 is a solid brass knocker in an urn style. Both are styling alternatives rather than dimensional matches, so confirm screw hole layout before reusing existing holes.
11) I want a knocker that also works as a door pull - what should I use instead of the Cal-Royal SSBDK234?
The SSBDK234 is a knocker on its own, packed with mounting screws for a straight two-screw install at 3-1/2" CTC. If the door also needs something to grab, the Emtek 86060 is a 4" bronze knocker with a ring pull, so the ring serves double duty on a courtyard or gate-style entry.
12) How does the Emtek 86060 sandcast bronze knocker differ from the Cal-Royal SSBDK234 for finish matching?
The Cal-Royal SSBDK234 is solid brass and comes in US3 polished brass, US15 satin nickel, and US10B antique bronze oiled, so it matches standard architectural finish schedules across a building. The Emtek 86060 is from the Sandcast Bronze series, a cast bronze product whose surface character reads differently from a plated brass finish. If the other trim on the opening is specified by US finish number, the Cal-Royal is the easier match.
13) Which door knocker should I standardize on across a multi-tenant building where units get numbered?
Two workable paths: the Cal-Royal SSBDK234 is a solid brass knocker meeting ANSI/BHMA A156.16 L23151 in a compact 2-1/8" x 3-3/4" footprint with 3-1/2" CTC holes and screws included, so every door gets the same drill pattern. If you want unit numbers on the knocker plate itself, the Trimco 620 is offered with optional engraving, which puts the identification on the hardware rather than on separate numerals.
14) Can a door knocker like the Cal-Royal SSBDK234 go on a fire rated door?
Anything that puts fasteners through a labeled fire door leaf changes the assembly, and the SSBDK234 mounts with through-screws on 3-1/2 inch centers. Treat a rated opening as off the table unless the door manufacturer's listing permits the prep. On non-rated entry doors in offices, schools, healthcare, retail, and government buildings, it is the intended application.
