Pamex DD01-180UL 180 Degree UL Door Viewer with 9/16" Bore for 1-3/8" to 2-1/4" Door

A 9/16 inch bore. If a previous viewer left a smaller hole, you'll need to open it up to 9/16; if the existing hole is larger, the 1-1/16 inch outside diameter of the trim ring is what covers it, so anything much over 9/16 risks the viewer body not gripping even though the ring hides the gap.

The DD01-180UL carries a UL fire rating of 20 minutes under UL File No. R25341, so it is the viewer to use in a 20 minute rated opening such as a typical apartment entry door. Drilling a non-rated viewer into a rated door voids the door's listing. If your opening needs a viewer with a different rating basis, other UL fire rated viewers we carry include the Ives U698 wide angle and the Ives U700.

The Pamex DD01-180UL tops out at 2-1/4 inches, so it won't reach through a thicker slab. For 2 to 2-1/2 inch doors, the Rockwood 621 is the UL listed 160 degree option. The Ives 701 is a one way brass viewer built for thicker doors. Measure the actual slab, not the frame, before ordering.

The Pamex DD01-180UL is a plain 180 degree viewer with no cover over the lens. If the tenant or occupant wants the inside eyepiece closed off, the Cal-Royal PRIULDV200 is a UL listed 200 degree viewer with a privacy cover, the Hager 1759 is a 185 degree 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 cover for 1-3/8 inch to 2 inch doors. The Trimco 977 adds a 200 degree lens with a heavy duty cover for 1-17/64 inch to 2-1/8 inch doors.

The Pamex DD01-180UL adjusts from 1-3/8 inches to 2-1/4 inches, so an opening past that range needs a viewer built for it. The Rockwood 621 covers 2 inches to 2-1/2 inches and is UL listed, which picks up the thickness the DD01-180UL stops at. Bore size differs between the two, so confirm the hole you are drilling or reusing before ordering.

The Pamex DD01-180UL starts at 1-3/8 inches, which leaves out thin slabs and cabinet-weight doors. The Rockwood 619 is a 160 degree viewer built for 11/16 inch to 1-1/16 inch door thickness, which is the range below where the Pamex begins. The viewing angle drops from 180 degrees to 160 degrees in that swap.

The Pamex DD01-180UL uses a glass lens with a 180 degree field of vision. For a wider cone, the Trimco 976 is a 200 degree viewer and the Cal-Royal PRIULDV200 is a UL listed 200 degree glass lens viewer. The Trimco 976 covers 1-17/64 inch to 2-1/8 inch door thickness, which is a slightly narrower range at the thick end than the Pamex.

No - the bore does not match. The Pamex DD01-180UL fits a 9/16 inch hole, while the Emtek 2610 solid brass door viewer is drilled for a 5/8 inch diameter hole. Going from the Emtek to the Pamex leaves the Pamex barrel loose in an oversized hole; going the other way means enlarging the existing bore. Check the hole already in the door before treating these two as interchangeable.

The Pamex DD01-180UL carries a UL fire rating of 20 minutes under UL file number R25341. Among the alternatives, the Ives U698 is a UL fire rated wide angle viewer at 190 degrees, the Ives U700 is a brass viewer with UL fire rating, the Ives U696 is a 150 degree fire rated viewer, the Ives 701 is a fire rated brass viewer for thicker doors at 120 degrees, and the Hager 1756 is a 185 degree viewer with fire rating for 2-1/8 inch doors. Match the rating on the door label to what the viewer carries before you drill a labeled door.

180 degrees through a glass lens, not plastic. That gets you the full width of a corridor or landing including someone standing flat against the wall beside the frame, which a narrower viewer misses. If you want more, the Trimco 976 and 977 are 200 degree viewers and the Cal-Royal PRIULDV200 uses a 200 degree glass lens. Narrower options run down to 160 degrees on the Rockwood 619, 620, 621 and 624.

The viewer itself is brass with a glass lens. Pamex builds this as a zinc die cast knocker with a brass viewer, so on the knocker-and-viewer combination the knocker body is zinc die cast. For a resident-facing entry door that gets handled daily, that's a metal barrel rather than a molded one, which matters because plastic viewer barrels crack when someone overtightens them on install.

Five finishes, all called out by BHMA number so they match against the rest of the door hardware: 605 bright brass, 613 oil rubbed bronze, 619 satin nickel, 622 matte black and 625 polished chrome. If your locksets and hinges are specified by those same codes, order the viewer in the matching number and it lines up across the opening.

Across a 1-3/8 to 2-1/4 inch spread, yes, one part number covers it. That range is wider than most competing viewers we stock, which is what makes it useful for a property manager standardizing across a portfolio: the Rockwood 620 stops at 2 inches, the Hager 1759 stops at 2-1/8, and the Trimco 975 and 976 run 1-17/64 to 2-1/8. Order in a single finish code and the whole property matches.

Both cover the common residential slab: the Pamex DD01-180UL adjusts from 1-3/8 inches to 2-1/4 inches, and the Rockwood 620 is rated for 1-3/8 inches to 2 inches. The lens differs - the Pamex is 180 degrees, the Rockwood 620 is 160 degrees. The Pamex viewer is brass and measures 1-1/16 inches in overall diameter on the face.

The Pamex DD01-180UL adjusts across 1-3/8 inches to 2-1/4 inches on a 9/16 inch bore, which takes in standard interior and most entry slabs in one part number. The Trimco 975 and 976 run 1-17/64 inches to 2-1/8 inches, and the Rockwood 620 runs 1-3/8 inches to 2 inches. For any door at 2 inches to 2-1/2 inches, the Rockwood 621 is the one that reaches, so a mixed-stock building with heavy entry doors may need a second part number alongside whichever viewer covers the rest.

The Pamex DD01-180UL is classified for residential use. On the commercial side, the Trimco 975 and 976 series and the Rockwood 619, 620 and 621 viewers are the ranges to work from, with Rockwood covering door thickness in three discrete bands - 11/16 inch to 1-1/16 inch, 1-3/8 inch to 2 inch, and 2 inch to 2-1/2 inch - so you pick by slab rather than adjusting one part.

The Pamex DD01-180UL is built with a zinc die cast knocker and a brass viewer, so the knocker and peephole come as one piece at the door face. If you want the viewer alone with no knocker plate, the Emtek 2610 solid brass door viewer and the Ives U700 brass viewer are viewer-only parts. Note the Emtek 2610 takes a 5/8 inch hole rather than the 9/16 inch bore the Pamex uses.

No - the Ives one-way viewers span a range of angles and none of them matches 180 degrees exactly. The Ives U698 is 190 degrees, the U696 is 150 degrees, and the 701 is 120 degrees and built for thicker doors. The Pamex DD01-180UL is 180 degrees on a glass lens. If the spec on the drawing calls a minimum viewing angle, read it against the specific Ives number rather than treating the series as one value.

Yes. The Pamex DD01-180UL is made in 613 oil rubbed bronze, along with 622 matte black, 625 polished chrome, 605 bright brass, and 619 satin nickel, so a fleet already standardized on a BHMA finish code can stay on the same number across the building.
