Trimco 976 Door Viewer - 200 degree

Yes. The 976 covers doors from 1-17/64 inches up to 2-1/8 inches thick, so a standard 1-3/4 inch commercial door sits comfortably in the middle of that range. That same range also takes 1-3/8 inch older interior doors and thicker fire door assemblies up to 2-1/8 inches, so one part number works across a mixed building instead of stocking a short-barrel and a long-barrel viewer.

Three build levels of the same viewer. The 976 is the base viewer. The 976U is the UL certified version, which is what you specify when the viewer goes into a labeled fire door. The 976U-CAP is the UL viewer with a cap, a hinged cover on the inside that blocks the lens so nobody can see in from the corridor side. For apartment, hotel and assisted living entry doors the CAP version is usually what residents want; for a back-of-house fire door with no privacy concern the plain 976U is enough.

Trimco's 976U-CAP is the UL viewer with a cap over the lens. If you want alternatives, the Cal-Royal PRIULDV200 is a UL listed privacy door viewer with a 200 degree glass lens and privacy cover, the Hager 1759 is a 185 degree one way viewer with a privacy flap that fits 1-3/8 to 2-1/8 inch doors, and the Rockwood 624 is a 160 degree viewer with a cover for 1-3/8 to 2 inch doors. The choice usually comes down to the viewing angle and the door thickness you are working with.

Not the Trimco 976. Its range stops at 2-1/8 inches, so on anything thicker the barrel will not draw up tight and you will not get a clean image. The Rockwood 621 is a UL listed 160 degree viewer built for 2 inch to 2-1/2 inch doors and is the one to specify for thick lead-lined, acoustic or heavy fire door assemblies.

The Ives U698 is the nearest wide angle one way viewer, at a 190 degree field and UL fire rated. The Trimco 976 covers doors from 1-17/64 inch to 2-1/8 inch and is offered in 605 bright brass, 613 oil rubbed bronze, 622 matte black, 625 bright chrome and 626 satin chrome, with 976U and 976U-CAP UL versions. If the opening needs a wide field and a fire label, either one answers it; the 976 gives you the broader finish range and a capped cover version.

For a thin leaf, the Rockwood 619 is a 160 degree viewer for 11/16 inch to 1-1/16 inch door thickness. The Trimco 976 starts at 1-17/64 inch, so anything under that goes to the 619.

The Trimco 976 is recorded as ADA compliant and is a commercial grade viewer, which is what an accessibility reviewer looks for on multifamily and hospitality entries. It also carries an ANSI/BHMA designation of L03172. Mounting height is the part ADA actually governs on a viewer, so set the barrel where your accessibility drawing calls for it.

Viewing angle decides how much of the corridor you see without opening the door. A standard 160 degree viewer, which is what the Trimco 976 carries, shows you who is directly outside and a good arc to either side. Wide angle optics at 190 to 200 degrees pull in someone standing flat against the wall beside the frame, which is why security-conscious multifamily and hospitality specs call for them. Trimco offers the series in both 160 and 200 degree optics; among other brands the Cal-Royal PRIULDV200 runs a 200 degree lens and the Ives U698 runs 190 degrees, while the Ives 701 is a narrower 120 degree viewer.

Only if you order the plain 976 or 976U. The cap comes as part of the 976U-CAP model, so pick that model number and the cover is on the part, nothing extra to add to the order. Trimco lists covers as an available option across the 975/976/977 door viewer family.

The Emtek 2610 is a solid brass door viewer bored for a 5/8 inch diameter hole. The Trimco 976 is a commercial viewer that is ADA compliant and carries ANSI/BHMA L03172, with UL versions in 976U and 976U-CAP. If the job is spec driven and needs the UL and BHMA reference, the 976 is the one that carries it; the 2610 is the solid brass viewer where those are not called out.

For a fleet of standard 1-3/8 inch to 2 inch leaves, the Rockwood 620 is a 160 degree viewer in that exact range, and the Rockwood 624 is the same range with a cover. The Trimco 976 spans 1-17/64 inch to 2-1/8 inch, so one part number covers those doors plus slightly thicker ones, and it is a commercial rated viewer that is ADA compliant.

The Hager 1756 is a 185 degree one way fire rated viewer listed for 2-1/8 inch doors. Where the leaves are mixed, the Trimco 976 runs 1-17/64 inch to 2-1/8 inch, so a single part number reaches across thinner doors and still lands on 2-1/8 inch, with 976U and 976U-CAP for the UL requirement.

Five finishes across every model in the series: 605 bright brass, 613 oil rubbed bronze, 622 matte black, 625 bright chrome and 626 satin chrome. All five are offered on the plain 976, the UL rated 976U and the 976U-CAP, so a property manager standardizing on 626 satin chrome across a building can match the non-rated and the fire door openings without a finish break.

It is built for exactly that kind of work. The 976 is a commercial grade viewer and Trimco lists the series for assisted living, hospitals and health care facilities, hospitality, multifamily and mixed-use, and commercial, industrial and manufacturing buildings. For patient room and resident room doors the 976U-CAP with the cover is the usual call, since it lets the occupant close off the lens from the inside.
