Sure-Loc DV180 11P – Frequently Asked Questions
1) Tenants want a viewer they can block from the inside - does the Sure-Loc 180 degree viewer have a privacy cover?
The Sure-Loc 180 degree viewer is described as a simple non-electronic viewer without a cover feature. If a closable cover is required, the Hager 1759 is a 185 degree one-way viewer with a privacy flap, the Cal-Royal PRIULDV200 is a UL listed privacy viewer with a 200 degree glass lens and privacy cover, the Rockwood 624 is a 160 degree viewer with cover, and the Trimco 977 is a 200 degree viewer with a heavy duty cover.
2) The door is 2-1/4 inches thick - will the Sure-Loc 180 degree door viewer suit it?
The Sure-Loc 180 degree viewer is built for standard residential entry doors. When the door is unusually thick, pick a viewer whose thickness range is stated: the Rockwood 621 covers 2 inch to 2-1/2 inch doors, the Hager 1756 is listed at 2-1/8 inches, and the Ives 701 is a one-way brass viewer for thicker doors with a 120 degree viewing angle. For thinner doors, the Rockwood 619 covers 11/16 inch to 1-1/16 inch.
3) What is the closest equivalent to the Sure-Loc 180 degree door viewer in viewing angle?
The Sure-Loc viewer offers a 180 degree field of view. The nearest angles in other lines are the Hager 1756 and Hager 1759 at 185 degrees and the Ives U698 at 190 degrees; going wider, the Trimco 976 and Cal-Royal PRIULDV200 are 200 degree viewers. Narrower options include the Ives U696 at 150 degrees, the Rockwood 619, 620, 621 and 624 at 160 degrees, the Trimco 975 at 160 degrees, and the Ives 701 at 120 degrees.
4) Does the Sure-Loc door viewer need batteries or wiring?
No power of any kind. It is a fully mechanical viewer, no wiring, batteries, or transformer, so it keeps working through an outage and there is nothing to service on a rental turn.
5) I manage apartments. Is a 180 degree viewer wide enough, or should I go wider?
At 180 degrees the Sure-Loc viewer shows the full face of the doorway, including someone standing flat against the wall beside it, which is the main reason to go past the older 120 to 160 degree viewers. If you want more, the Trimco 976 and Trimco 977 are 200 degree viewers, and the Cal-Royal PRIULDV200 is a 200 degree glass lens viewer. For less, the Ives 701 is 120 degrees and the Rockwood 619, 620 and 624 are 160 degrees.
6) What size hole do I drill for a door viewer, and is the Sure-Loc a simple retrofit?
The Sure-Loc viewer is a two-piece screw-together residential viewer that goes into an existing entry door with no other hardware changes. Bore size varies by model, so match the viewer to the hole you have: the Emtek 2610 solid brass viewer, for example, is specified for a 5/8 inch diameter hole, which is a common existing peephole bore. If a previous viewer is coming out, measure the hole before choosing the replacement.
7) Can I use this viewer on a thin door, like a 1 inch interior or screen door?
Thin slabs are outside what a standard residential entry viewer is set up for. The Rockwood 619 is the one to use there, rated for 11/16 inch to 1-1/16 inch door thickness. The Trimco 975 also starts low at 1-17/64 inch and runs to 2-1/8 inch if the door is somewhere in between.
8) Is the Cal-Royal PRIULDV200 a drop-in substitute for the Sure-Loc 180 degree door viewer?
Not in function. The Sure-Loc unit is a plain residential 180 degree viewer with no power or wiring. The Cal-Royal PRIULDV200 is UL listed, uses a 200 degree glass lens, adds a privacy cover, and is catalogued with a Privacy/Bed/Bath product function, so it brings a different feature set and a wider lens to the same 5/8 inch class of bore.
9) Standardizing viewers across a multi-family property - how do the Sure-Loc 180 degree viewer and the Trimco 975 series differ?
The Sure-Loc 180 degree viewer is a residential accessory with a 180 degree field of view and four finishes: vintage bronze, satin nickel, polished chrome, and flat black. The Trimco 975 is a 160 degree viewer covering 1-17/64 inch to 2-1/8 inch door thickness, with the 976 at 200 degrees and the 977 adding a heavy duty cover over the same thickness range, so one Trimco series can cover several viewing angles and cover options across a building.
10) What finishes does the Sure-Loc 180 degree door viewer come in?
Four finishes, and that is the full set: 11P Vintage Bronze, 15 Satin Nickel, 26 Polished Chrome, and FBL Flat Black. If you are standardizing a building, Satin Nickel and Flat Black are the two that most commonly match current residential entry sets.
