Ives IVE-U701-B26D – Frequently Asked Questions

1) What size hole do I drill for an Ives U701 peephole?
One 1/2 inch hole, drilled straight through the door. The trim itself is 5/8 inch diameter, so it covers the bore with a little margin on each side. Ives suggests mounting at 60 inches from the floor. The body goes in from the inside and the exterior lens threads onto it.
2) Can I put a door viewer in a fire rated door without voiding the rating?
With the Ives U701, yes on doors rated up to 90 minutes. It is UL listed for 90 minute fire doors, which is what lets you bore a fire door for it. Not every viewer carries that listing, so on a rated opening this is the spec to check before you drill. Among the alternatives, the Rockwood 621 and the Hager 1756 are also UL listed viewers.
3) Can someone unscrew an Ives U701 viewer from outside the door?
No. The U701 uses one-way threads, so it goes together from the interior side and cannot be backed out from the exterior. That is the security case for it on apartment and condo entry doors, where the outside face is in a public corridor.
4) What door viewer works on a 2-3/8 inch door if the Ives U701 is not available?
The Rockwood 621 covers 2 inch to 2-1/2 inch door thickness, so it spans the same thick-door territory as the U701 range of 2-1/8 inch to 2-5/8 inch and is UL listed. The Rockwood 621 offers a 160 degree field of view against the 120 degree view of the U701. Both take a through-bored hole in the door face; the U701 uses a 1/2 inch hole with a 5/8 inch diameter trim footprint.
5) I need a wider field of view than 120 degrees on an apartment entry door - what are my options?
The U701 gives a 120 degree angle of view. For a wider cone, the Trimco 976 and the Trimco 977 with heavy duty cover are both 200 degree viewers covering 1-17/64 inch to 2-1/8 inch door thickness, and the Cal-Royal PRIULDV200 is a UL listed privacy viewer with a 200 degree glass lens. Note the thickness ranges: the Trimco 976 and 977 top out at 2-1/8 inch, which is where the U701 range begins, so confirm the leaf thickness before switching.
6) I need a peephole with a privacy cover for tenant units - what should I order?
The U701 is a plain-lens viewer and takes an optional cover accessory for privacy. If you want the cover built into the part, 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, the Rockwood 624 is a 160 degree viewer with a cover for doors 1-3/8 inch to 2 inch, 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. All three sit below the 2-1/8 inch to 2-5/8 inch range the U701 serves, so match the cover choice to the actual leaf thickness.
7) How wide is the field of view on the Ives U701 brass viewer?
120 degrees. That shows you the landing directly in front of the door but not much to either side of the frame. If a resident needs to see someone standing tight against the wall beside the opening, a wider lens is the better call, the Trimco 976 and 977 are 200 degree and the Cal-Royal PRIULDV200 uses a 200 degree glass lens. Wider angle viewers usually need a larger bore, so decide before you drill.
8) Does the Ives U701 come with a privacy cover over the lens?
No cover ships with the U701 itself, covers are an optional accessory. If a privacy flap matters to your residents, the Hager 1759 and the Rockwood 624 include one, and the Cal-Royal PRIULDV200 comes with a privacy cover. On a rated opening, keep the fire listing in mind when you pick.
9) Does the Ives U701 meet ANSI/BHMA standards for a spec job?
It meets ANSI/BHMA A156.16 under function number L23223, the auxiliary hardware standard that covers door viewers. Pair that with the UL listing for 90 minute fire doors and it will satisfy most submittal reviews on rated residential openings. Note that Ives classes the U701 as residential grade, so check that against your spec if the drawing calls for commercial.
10) My door is thicker than 2-5/8 inches, can I still use an Ives viewer?
Yes, with an extension. Ives offers viewer extensions in 3/8 inch increments to push the U701 past its native 2-1/8 to 2-5/8 inch range. Measure the actual door slab, including any applied panel or cladding, then add extensions to cover the difference. The 1/2 inch bore does not change.
11) Does the Emtek 2610 door viewer fit the same hole as the Ives U701?
Yes on the hole size in the sense that matters for the door prep: the Emtek 2610 is a solid brass viewer for a 5/8 inch diameter hole, and the U701 is a brass viewer with a 5/8 inch diameter trim, drilled with a 1/2 inch hole and installed on one-way threads. Where they part company is the leaf: the U701 is built for doors 2-1/8 inch to 2-5/8 inch thick and is UL listed for 90 minute fire doors, so on a fire-rated opening confirm the listing before swapping in the Emtek.
12) What is the difference between the Rockwood 619, 620 and 621 door viewers and the Ives U701?
The three Rockwood viewers are all 160 degree units separated by door thickness: the 619 for 11/16 inch to 1-1/16 inch, the 620 for 1-3/8 inch to 2 inch, and the 621 for 2 inch to 2-1/2 inch, with the 621 UL listed. The Ives U701 is the thick-door end of the same idea, covering 2-1/8 inch to 2-5/8 inch at 120 degrees with a brass body, one-way tamper-resistant threads, and UL listing for 90 minute fire doors. Pick by measuring the leaf first; the viewing angle follows from that choice.
13) Is the Cal-Royal PRIULDV200 the same thing as the Ives U701?
They are both UL listed door viewers but they are not the same part. The Cal-Royal PRIULDV200 is a privacy viewer with a 200 degree glass lens and a privacy cover, catalogued for a privacy, bed and bath function. The Ives U701 is a 120 degree brass viewer with one-way tamper-resistant threads, UL listed for 90 minute fire doors, sized for doors 2-1/8 inch to 2-5/8 inch thick. If the requirement is a resident-controlled privacy shutter, the Cal-Royal is the closer fit; if it is a thick rated leaf with a tamper-resistant exterior, the U701 is.
14) What is the Ives U701 door viewer made of, and will it hold up on an exterior entry door?
Solid brass body with a glass lens, not plastic. Brass resists corrosion on an exterior face, and a glass lens will not haze or scratch the way an acrylic one does over years of wiping. It is built for entry door duty on houses, townhomes, apartments, and assisted living resident doors.
15) Which part number do I order for an oil-rubbed bronze Ives U701?
U701-B10B is the 613 satin bronze oil-rubbed version. The base model is U701 and the finish suffix identifies the rest: B4 for 606 satin brass, B15 for 619 satin nickel, B26 for 625 bright chrome, B26D for 626 satin chrome, 643E for aged bronze, and BLK for 622 matte black. Order by the full suffixed number so the finish comes right.
16) Which door viewer matches a satin chrome or matte black finish package across a building?
The Ives U701 is offered in 626 satin chrome, 625 bright chrome, 619 satin nickel, 606 satin brass, 613 satin bronze oil-rubbed, 643E aged bronze, and 622 matte black, so one part number covers most standard finish schedules across a fleet of units. Among the comparable viewers, the Rockwood 621 is a UL listed 160 degree unit for 2 inch to 2-1/2 inch doors if the thickness pushes past what the U701 serves.
