Rockwood 627 UL Rated 190 Degree Door Viewer with Heavy Duty Privacy Cover for 1-3/8" x 2-1/4" Doors

It is UL fire rated for 1-1/2 hours, which is a 90 minute opening. That covers the rated corridor and stair doors you find in apartment buildings, hotels and dorms. Cutting a 9/16 inch through-bore is what the rating is based on, so drill it to that size and no larger.

The Rockwood 627 is the one that goes that deep. Its range runs to 2-1/4 inches. Most of the comparable viewers stop short of that: the Trimco 975, 976 and 977 are all listed at 1-17/64 to 2-1/8 inches, and the Hager 1759 with privacy flap tops out at 2-1/8 as well. On a full 2-1/4 inch slab those will not thread through.

Yes. The Ives U698 is a one-way wide angle door viewer, UL fire rated, with a 190 degree view - the same viewing angle as the Rockwood 627, without a cover over the eyepiece. The Rockwood 627 is UL fire rated for 1-1/2 hours and adds a heavy duty privacy cover so the occupant can block the view in from outside the room. Where the opening only needs the lens, the U698 covers it; where the room also has to be shielded from the corridor side, the 627 is the one that does both.

The Rockwood 627 pairs a 190 degree lens with a heavy duty privacy cover that stops anyone seeing into the room from the corridor side. Built around the same idea: the Trimco 977 is a door viewer with a heavy duty cover at 200 degrees, and the Cal-Royal PRIULDV200 is a UL listed privacy door viewer with a 200 degree glass lens and privacy cover. The Hager 1759 handles it with a privacy flap over a 185 degree one way lens. All of these are covered viewers rather than open-lens viewers, so any of them will satisfy a spec that calls for the occupant to be able to block the eyepiece.

The Rockwood 627 is rated for door thicknesses of 1-3/8 inch through 2-1/4 inch, so it reaches the full 2-1/4 inch. The Trimco 975, 976 and 977 viewers are each rated 1-17/64 inch to 2-1/8 inch, and the Hager 1759 runs 1-3/8 inch to 2-1/8 inch, so those stop short of a 2-1/4 inch door. The Hager 1756 is built for a 2-1/8 inch door. The Ives 701 is a one-way brass viewer made for thicker doors, with a 120 degree viewing angle. On a heavy 2-1/4 inch door, the Rockwood 627 and the Ives 701 are the two to look at.

No. The Emtek 2610 is a solid brass door viewer for a 5/8 inch diameter hole, while the Rockwood 627 installs in a 9/16 inch hole. A door bored 5/8 inch is oversize for the 627, and the barrel will not grip in it. If the door is already drilled at 5/8 inch, stay with a viewer sized for that bore; specify the Rockwood 627 when the door is being drilled fresh at 9/16 inch, or on a door bored 9/16 inch for a previous viewer.

The cover sits on the room side of the viewer and closes over the eyepiece, which stops anyone in the corridor from seeing in through the lens when the viewer is not in use. It is the heavy duty version of that cover rather than a light flap. On a guest room, dorm room or apartment entry door this is the difference between a plain peephole and one that cannot be reversed on the occupant, and it is why the 627 is set up as a privacy, bed and bath function part.

Yes. The Rockwood 627 sees 190 degrees, and if you want more the Trimco 976 and the Cal-Royal PRIULDV200 are both 200 degree viewers, the Cal-Royal with a glass lens and a privacy cover. Going the other way, narrower options include the Trimco 975 at 160 degrees, the Ives U696 at 150 degrees and the Ives 701 at 120 degrees. Angle is what decides how much of the landing you can see without opening the door, so on a wide corridor or a recessed entry the 190 and 200 degree units are the ones worth paying attention to.

The Rockwood 627 is UL fire rated for 1-1/2 hours. Several alternatives carry a fire rating as well: the Ives U696 at 150 degrees, the Ives U698 at 190 degrees, the Ives U700 one-way brass viewer, and the Ives 701 at 120 degrees are all fire rated, and the Hager 1756 is a 185 degree one way viewer with a fire rating. The Cal-Royal PRIULDV200 is a UL listed privacy viewer with a 200 degree glass lens. Sort the group by viewing angle and whether the opening needs a cover, since fire rating alone does not separate them.

They are close but not identical. Both give the occupant a cover over the eyepiece - the Rockwood 627 with a heavy duty privacy cover, the Hager 1759 with a privacy flap on a 185 degree one way lens against the 627's 190 degrees. The difference that decides most jobs is door thickness: the Hager 1759 is rated 1-3/8 inch to 2-1/8 inch, and the Rockwood 627 is rated 1-3/8 inch to 2-1/4 inch. On doors up through 2-1/8 inch either one fits the opening; above that, the 627 is the one still in range.

Both are wide angle viewers with a heavy duty cover over the eyepiece. The Trimco 977 views at 200 degrees and is rated for doors 1-17/64 inch to 2-1/8 inch; the Rockwood 627 views at 190 degrees, is rated for doors 1-3/8 inch to 2-1/4 inch, is brass, and is UL fire rated for 1-1/2 hours. The Trimco 977 reaches down to thinner doors at 1-17/64 inch, the Rockwood 627 reaches up to thicker ones at 2-1/4 inch, so the door being drilled usually picks the winner.

Two finishes: bright chrome (CRM) and black (BLK). Chrome reads as the bright nickel and chrome hardware most apartment entries are trimmed with, black suits dark bronze and matte black packages. The body is brass underneath either finish, so it holds up on a door that gets used every day. Ordering the same finish across a floor keeps the viewers consistent even where the locksets came from different jobs.

Nothing beyond the hole. There is no mortise, no strike and no faceplate prep, just a 9/16 inch bore straight through the door at eye height. The two halves of the viewer thread into each other through that bore and clamp the door between them, which is why the 1-3/8 to 2-1/4 inch thickness range matters more than anything else on the order. One viewer per door, and it goes into a wood or hollow metal door the same way.

The Rockwood 627 views at 190 degrees. For a tighter cone, the Ives 701 is a one-way brass viewer at 120 degrees, the Ives U696 is a one-way fire rated viewer at 150 degrees, and the Trimco 975 views at 160 degrees. The Hager 1756 and 1759 both sit at 185 degrees. A narrower lens shows less of the wall on either side of the opening; a wider one shows more of the approach to the door.

The Rockwood 627 is brass. Among the alternatives, the Emtek 2610 is a solid brass door viewer, the Ives U700 is a one-way brass viewer with a UL fire rating, and the Ives 701 is a one-way brass viewer for thicker doors. Brass matters where the eyepiece is exposed to weather at an entry door or where the finish has to hold up to constant handling in a corridor.
