Cal-Royal DV90-US26 – Frequently Asked Questions

1) What size hole do I need to drill for a Cal-Royal DV90 or DV180 door viewer?
Two different bores here, and they aren't interchangeable. The DV90 and DV91 use a 1/2 inch bore. The DV180 needs a 9/16 inch bore. Drill the 1/2 inch hole and you cannot later drop a DV180 into it without opening the hole up, so pick the model before the door gets prepped.
2) I already drilled a 9/16 inch hole for a peephole. Which Cal-Royal viewer goes in it?
That's the DV180, the 180 degree Cal-Royal viewer bored at 9/16 inch. It works in doors 1-3/8 to 1-3/4 inches thick and comes packed with its screws. The DV90 and DV91 are 1/2 inch bore, so they'd sit loose in a 9/16 hole.
3) Are Cal-Royal DV90 door viewers ANSI/BHMA rated for commercial buildings?
Yes. The DV90 and DV91 conform to ANSI/BHMA A156.16, L23172. The DV180 conforms to A156.16 under L23151. That's the auxiliary hardware standard a spec writer or facilities buyer will be looking for on a viewer, and the whole line is built as commercial hardware rather than residential.
4) What is a direct substitute for a Cal-Royal DV90 door viewer on a 1-3/4 inch commercial door?
The Cal-Royal DV90 is a 160 degree viewer for doors 1-3/8 inch to 2 inch thick, and the Rockwood 620 is a 160 degree door viewer listed for the same 1-3/8 inch to 2 inch door thickness range. That matches both the viewing angle and the door thickness window, so a 1-3/4 inch door prepped for one takes the other. The Trimco 975 is also a 160 degree viewer, with a wider stated range of 1-17/64 inch to 2-1/8 inch, which covers a 1-3/4 inch door as well.
5) I need a fire rated door viewer for a rated opening. Can I use a Cal-Royal DV90 or DV91?
The Cal-Royal DV90 and DV91 conform to ANSI/BHMA A156.16 L23172 and the DV180 to A156.16 L23151. When the opening carries a fire label and the specification calls for a fire rated viewer by name, the Ives U696 is a 150 degree one way viewer carrying a fire rating, the Ives U698 is a 190 degree wide angle viewer that is UL fire rated, the Ives U700 is a one way brass viewer with a UL fire rating, and the Hager 1756 is a 185 degree one way viewer with a fire rating. Those are the ones to quote when the drawing calls out a fire rated viewer.
6) What door viewer should I use instead of a Cal-Royal DV180 on a door thicker than 2 inches?
The Cal-Royal DV180 fits doors 1-3/8 inch to 1-3/4 inch thick, so a door over 2 inches is outside its range. The Rockwood 621 is a UL listed 160 degree viewer for doors 2 inch to 2-1/2 inch thick. The Hager 1756 is a 185 degree one way viewer listed at 2-1/8 inch door thickness, and the Trimco 976 is a 200 degree viewer covering 1-17/64 inch to 2-1/8 inch. Measure the leaf and pick the one whose range brackets it.
7) Which door viewer has a privacy cover or flap instead of an open lens like the Cal-Royal DV90?
The Cal-Royal DV90 and DV91 use a plastic lens with no cover. If the tenant wants the eyepiece closed off from the inside, the Hager 1759 is a 185 degree one way viewer with a privacy flap for doors 1-3/8 inch to 2-1/8 inch thick, the Rockwood 624 is a 160 degree viewer with a cover for 1-3/8 inch to 2 inch doors, and the Trimco 977 is a 200 degree viewer with a heavy duty cover for 1-17/64 inch to 2-1/8 inch doors. The Rockwood 624 covers the same door thickness range as the DV90.
8) Will a Rockwood 619 door viewer work in place of a Cal-Royal DV90?
No. The Rockwood 619 is a 160 degree viewer for doors 11/16 inch to 1-1/16 inch thick, which is a thin door application. The Cal-Royal DV90 fits doors 1-3/8 inch to 2 inch thick, so the two do not overlap at any thickness. For a standard 1-3/4 inch commercial leaf the matching Rockwood is the 620, listed at 1-3/8 inch to 2 inch.
9) Can I drop an Emtek 2610 into a hole bored for a Cal-Royal DV90 or DV180?
Check the bore before you order. The Emtek 2610 is a solid brass door viewer for a 5/8 inch diameter hole. The Cal-Royal DV90 and DV91 use a 1/2 inch bore and the DV180 a 9/16 inch bore, so all three Cal-Royal models go into a hole smaller than the Emtek needs. An existing 5/8 inch hole can be dressed up to accept the Emtek, but a Cal-Royal viewer will not fill a 5/8 inch bore, and a hole drilled at 1/2 inch or 9/16 inch has to be enlarged for the Emtek.
10) Do I have to buy Cal-Royal door viewers by the box?
Yes, the Cal-Royal brass viewers ship as a box of 24 pieces, one finish and one model per box. Each viewer inside is individually poly-bagged, so you can hand them out door by door to a crew without them rattling loose. For a property manager fitting out a floor of units or a contractor on a multi-tenant job, 24 is the working unit. It is not set up for buying a single viewer.
11) What finishes do the Cal-Royal brass door viewers come in?
Seven finishes across the range: US3 polished brass, US5 antique brass, US10B antique bronze oiled, US15 satin nickel, US19 flat black, US26 polished chrome and US26D satin chrome. All three models, DV90, DV91 and DV180, are offered in each of those, so you can hold one finish across a building even if the door thicknesses force you between models.
12) Is there a straight substitute for the Cal-Royal DV90 with the same door thickness range?
The Rockwood 620 is the closest match: 160 degree viewing angle for 1-3/8 inch to 2 inch doors, the same angle and the same thickness range as the DV90. Rockwood also lists the 624, same 1-3/8 to 2 inch range at 160 degrees but with a cover over the eyepiece if the tenant wants the view blocked from the corridor side.
13) Can I use a Cal-Royal DV90 viewer on a thin interior or cabinet-thickness door?
No. The DV90 and DV91 bottom out at 1-3/8 inches, and so does the DV180, so anything thinner than that leaves the two halves unable to thread up tight. For a thin door the Rockwood 619 is the one to look at, a 160 degree viewer built for 11/16 inch to 1-1/16 inch stock.
14) What is the difference between the Cal-Royal DV91 and a Trimco 976 door viewer?
The Cal-Royal DV91 gives a 180 degree viewing angle through a 1/2 inch bore and fits doors 1-3/8 inch to 2 inch thick. The Trimco 976 is a 200 degree viewer in the 976 Series with a door thickness range of 1-17/64 inch to 2-1/8 inch. The Trimco sweeps a wider field and reaches further at both ends of the thickness range; the Cal-Royal is bored at 1/2 inch and comes in seven architectural finishes including US3 polished brass, US15 satin nickel, US19 flat black and US26D satin chrome.
15) I need a narrower field of view than 180 degrees for a viewer on a thicker door. What are my options?
The Cal-Royal DV91 and DV180 both give 180 degrees and the DV90 gives 160 degrees. For a narrower field on a heavier leaf, the Ives 701 is a one way brass door viewer for thicker doors with a 120 degree viewing angle and carries a fire rating. The Ives U696 sits between at 150 degrees, also fire rated. Both are one way viewers, so the occupant sees out and the corridor side does not see in.
16) I am standardizing viewers across a 24 unit building. Which viewer covers the widest range of door thicknesses in one part number?
For a mixed set of leaves, the Trimco 975 at 160 degrees and the Trimco 976 at 200 degrees both list a door thickness range of 1-17/64 inch to 2-1/8 inch, the widest single range in this class, and the Hager 1759 covers 1-3/8 inch to 2-1/8 inch. The Cal-Royal DV90 and DV91 cover 1-3/8 inch to 2 inch and ship as a box of 24 pcs, which lines up with a 24 unit rollout on one part number and one finish.
17) What is the closest match to a Cal-Royal DV180 in a 180 degree viewer from another brand?
The Cal-Royal DV180 is a 180 degree viewer with a 9/16 inch bore for doors 1-3/8 inch to 1-3/4 inch thick, offered in finishes including US3 polished brass and US26 polished chrome. In a comparable wide field, the Hager 1759 is a 185 degree one way viewer for 1-3/8 inch to 2-1/8 inch doors, the Hager 1756 is a 185 degree one way viewer with a fire rating at 2-1/8 inch, and the Ives U698 is a 190 degree wide angle viewer that is UL fire rated. Confirm the bore diameter each requires against the hole you have.
18) Do Cal-Royal door viewers come with screws, or do I need to order fasteners separately?
The DV180 is packed with its screws. The DV90 and DV91 are individually poly-bagged and boxed. All three are the two-piece thread-together type that tightens through the bore, so no separate mounting kit is called out for them.
19) Is the lens on the Cal-Royal DV90 glass or plastic?
Plastic. The DV90 and DV91 are built with a plastic lens in a brass body. That matters if you are specifying for an opening where a glass optic is called out, but for standard commercial entry and multi-tenant use the plastic lens is what these carry.
20) What size hole in the door face does the Cal-Royal DV180 cover?
The DV180 measures 3-1/2 x 6-7/8 inches. Worth knowing before you lay out the door, since the trim footprint is larger than the 9/16 inch bore itself and needs clear face on the stile at your chosen eye height.
