Hager 1756-26D – Frequently Asked Questions

1) What size hole do I need to drill for a Hager 1756 peephole?
Bore a 9/16 inch (14 mm) hole through the door. Mount height is typically around 58 inches off the floor. If you are replacing an existing viewer, measure the old bore first: a smaller existing hole can be opened up to 9/16, but a hole already drilled larger than 9/16 will leave the trim ring of the 1756 with nothing to seat against.
2) Can I use the Emtek 2610 in place of the Hager 1756?
They are not interchangeable at the door prep. The Emtek 2610 is a solid brass door viewer that takes a 5/8 inch diameter hole, while the Hager 1756 requires a 9/16 inch hole. If a 9/16 inch bore is already drilled, the Emtek will not tighten in it, and if a 5/8 inch bore exists the Hager will sit loose. The Hager 1756 is also UL10B 90 minute fire rated, which matters if the opening is a fire-rated assembly.
3) My door is thicker than 2-1/8 inches - what door viewer should I order instead of the Hager 1756?
The Hager 1756 is set up for a 2-1/8 inch door thickness, so a heavier slab needs a different viewer. The Rockwood 621 is a UL listed 160 degree viewer built for 2 inch to 2-1/2 inch doors and covers that range. For thicker doors in the Ives line, the Ives 701 is a one-way brass viewer described for thicker doors with a 120 degree viewing angle, and it is fire rated. Measure the finished slab including any applied panel before you pick.
4) What door viewer do I use on a thin door where the Hager 1756 will not work?
The Hager 1756 is specified at 2-1/8 inch door thickness and will not close up on a thin slab. The Rockwood 619 is a 160 degree viewer built for 11/16 inch to 1-1/16 inch doors, which is the range for thin panels and light interior doors. Between the two extremes, the Rockwood 620 is a 160 degree viewer for 1-3/8 inch to 2 inch doors, the common range for a standard entry slab.
5) How wide is the view on the Hager 1756 compared to other door viewers?
185 degrees, which is near the top of what viewers offer and wide enough to pick up someone standing flat against the door frame. For reference against other viewers we carry: the Ives U698 is 190 degrees and UL fire rated, the Trimco 976 is 200 degrees, and the Rockwood 620 and Ives U696 sit lower at 160 and 150 degrees. If the tenant complaint is blind spots at the edge of the frame, anything in the 185 to 200 range solves it.
6) Can someone outside see into the apartment through a Hager 1756 viewer?
No. The 1756 is a one way viewer, so the optics pass image from the corridor side inward only and an outside observer gets no useful view of the unit. If you want a physical barrier as well, the Cal-Royal PRIULDV200 adds a privacy cover over the lens, and the Rockwood 624 is a 160 degree viewer supplied with a cover.
7) I need to standardize door viewers across an apartment building. Is the Hager 1756 the right one to spec?
For a multi-family fit-out it works well because one part number covers 1-3/8 through 2-1/8 inch doors, so units with different slab thicknesses all take the same viewer and the same 9/16 inch bore. The 90 minute UL10B rating also lets the same part go into the rated corridor doors, so you are not carrying a separate fire-rated SKU. Where a door is thicker than 2-1/8 inches you will need a different viewer, such as the Rockwood 621 for 2 to 2-1/2 inch doors.
8) I need a fire rated door viewer but a narrower field is fine - what else works?
The Ives line covers the narrower angles with the same fire rating. The Ives U696 is a one-way viewer with a 150 degree viewing angle and is fire rated, and the Ives 701 is a one-way brass viewer with a 120 degree viewing angle for thicker doors, also fire rated. The Ives U700 is a one-way brass viewer carrying a UL fire rating as well. All of these are one-way like the Hager 1756, so the privacy behavior is the same; the difference is how much of the corridor or landing you see.
9) I need a viewer with a cover over the eyepiece - what should I order?
The Hager 1756 is a one-way viewer without a cover, so if the tenant or facility wants the eyepiece blocked, look at the covered models. The Rockwood 624 is a 160 degree viewer with a cover for 1-3/8 inch to 2 inch doors. The Trimco 977 is a 200 degree viewer with a heavy duty cover for 1-17/64 inch to 2-1/8 inch doors, which suits higher-traffic openings. The Cal-Royal PRIULDV200 is a UL listed privacy viewer with a 200 degree glass lens and a privacy cover, and it is a privacy, bed and bath function part.
10) Which finishes does the Hager 1756 door viewer come in?
Three orderable finishes on the 1756: 605 bright brass, 619 satin nickel, and 626 satin chrome. Match to the lockset on the same door rather than to the hinges, since 626 satin chrome and 619 satin nickel read very differently in daylight and a mismatched viewer is the first thing a tenant notices at eye level.
11) What is the Hager 1756 viewer made of, and will it hold up in an exterior corridor?
Solid brass body. Brass resists corrosion, which matters on exterior-facing entry doors and open breezeway corridors where a plated pot metal viewer chalks up. The Emtek 2610 and Ives U700 are the other brass viewers we stock if you want a brass body in a different bore or angle.
