Deltana 55211-UL Door Viewer, UL Listed

The Deltana 55211-UL is a UL Listed solid brass viewer with a 200 degree view range and no cover in its description. When a resident wants the interior eyepiece blocked, the Cal-Royal PRIULDV200 is a UL Listed privacy door viewer with a 200 degree glass lens and a privacy cover, the Hager 1759 is a 185 degree one way viewer with a privacy flap for 1-3/8 inch to 2-1/8 inch doors, and the Rockwood 624 is a 160 degree viewer with a cover for 1-3/8 inch to 2 inch doors. The Trimco 977 pairs a 200 degree view with a heavy duty cover for higher traffic openings.

The Deltana 55211-UL is UL Listed with a 200 degree view range in solid brass. If the opening needs a fire rated viewer at a comparable wide angle, the Ives U698 is a one-way wide angle door viewer, UL fire rated, with a 190 degree view. The Trimco 976 is also a 200 degree viewer and fits doors from 1-17/64 inch to 2-1/8 inch. Match the view angle you need first, then confirm the door thickness at the bore.

The Deltana 55211-UL door viewer is specified for 1-3/8 inch door thickness. For thicker doors, the Rockwood 621 is a UL Listed 160 degree viewer for 2 inch to 2-1/2 inch doors, and the Hager 1756 is a 185 degree one way viewer with a fire rating for 2-1/8 inch doors. The Trimco 975 covers 1-17/64 inch through 2-1/8 inch in a single part. Measure the leaf at the bore location before ordering, since a viewer sized short of the thickness will not draw the two halves together.

The Deltana 55211-UL carries a UL Listed certification and is classed for residential use. That is not interchangeable with a viewer specified for a fire rated opening. The Ives U700 is a one-way brass door viewer with a UL fire rating, the Ives U696 is a fire rated one-way viewer with a 150 degree viewing angle, and the Ives 701 is a fire rated one-way brass viewer for thicker doors with a 120 degree angle. On a labeled door, order against the fire rating on the part.

They are not the same specification. The Deltana 55211-UL is a solid brass UL Listed viewer with a 200 degree view range. Viewers described as one-way include the Ives U700, the Ives U696 at 150 degrees, the Ives U698 at 190 degrees, the Ives 701 at 120 degrees for thicker doors, and the Hager 1756 and 1759 at 185 degrees. If a spec calls out one-way construction, order one of those rather than substituting on view angle alone.

The Deltana 55211-UL is specified for 1-3/8 inch doors and comes in nine finishes including Oil Rubbed Bronze, Polished Chrome, Brushed Nickel and Antique Brass, so it will match trim across a floor as long as the leaves are 1-3/8 inch. Where thicknesses vary, single parts that span a range are easier to standardize on: the Trimco 975 and Trimco 976 both fit 1-17/64 inch to 2-1/8 inch, the Hager 1759 fits 1-3/8 inch to 2-1/8 inch, and Rockwood splits the range across 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.

The Deltana 55211-UL has a 200 degree view range. Rockwood viewers in the 619, 620, 621 and 624 are 160 degree, the Hager 1756 and 1759 are 185 degree, the Ives U698 is 190 degree, and the Ives U696 is 150 degree. A wider angle shows more of the landing directly against the door face, which matters at a recessed entry; a narrower angle covers less of that near field. The Trimco 976 and Trimco 977 also give 200 degrees if the door is thicker than 1-3/8 inch.

The Deltana 55211-UL is built for 1-3/8 inch doors, which is the standard interior and many residential entry leaves. On a thinner leaf, the Rockwood 619 is a 160 degree viewer for 11/16 inch to 1-1/16 inch door thickness, and the Trimco 975 starts at 1-17/64 inch. Both barrels are cut for those ranges, so the eyepiece seats flush instead of standing proud of the interior face.

Both suit a 1-3/8 inch leaf. The Deltana 55211-UL is solid brass, UL Listed, with a 200 degree view range and nine finishes including PVD Polished Brass, Antique Nickel, Brushed Chrome and Paint Black. The Rockwood 620 is a 160 degree viewer covering 1-3/8 inch to 2 inch door thickness, so one part number spans a building with mixed leaves. Choose on view angle and finish match if every door is 1-3/8 inch; choose on thickness coverage if they are not.

Each. The price shown is per viewer, so if you are outfitting a corridor of apartment doors, order one per door and pick the finish per door to match existing trim.
