Ives 3CB1WT 4.5x5 652 – Frequently Asked Questions

1) What is a wide throw hinge like the Ives 3CB1WT for, and when do I actually need one?
Wide throw is what you order when the door has to swing clear of something the frame is in the way of: deep trim or casing, a return wall, or a wheelchair opening where you need the full clear width. A standard hinge only lets the door back off the frame by so much. The 3CB1WT is the wide throw version of the steel 3 knuckle concealed bearing full mortise hinge, so the leaves are wider than tall in several of the offerings (6 inch by 5 inch, for example) to push the door further off the jamb. If the door swings free and you don't need extra clearance, a standard width hinge in the same weight class is the simpler order.
2) How much door weight can the Ives 3CB1WT hinge carry, and how much traffic?
Rated for medium weight doors up to 150 lbs at medium frequency, up to 400 cycles per day. That covers most commercial office, classroom, and tenant corridor openings. A heavy solid core or lead lined door, or a high traffic entry running well past 400 cycles a day, wants a heavy weight hinge instead: the Don-Jo HWBB84545 or the Hager BB1168 are heavy duty full mortise ball bearing options.
3) Will the Ives 3CB1WT hinge work on both hollow metal and wood doors?
Both. It ships with wood and machine screws in the box, 12-24 x 1/2 inch undercut flat head machine screws for the hollow metal frame or metal door, and 12 x 1-1/4 inch flat head wood screws for a wood door. You don't have to source fasteners separately for either substrate.
4) Does the Ives 3CB1WT fit a standard hollow metal frame hinge prep?
It's certified to ANSI/BHMA A156.7 template hinge dimensions, which is the standard commercial frames and doors are prepped to. It's furnished square corner, so it drops into a square corner prep. If your existing doors are cut with radius corners you would need the rounded corner option (RC-1/4 or RC-5/8) rather than the standard square corner version.
5) How do I keep an outswing exterior door hinge from being pulled apart, on the Ives 3CB1WT?
Order it with NRP, the non-removable pin option, or with the SH security stud. NRP stops the pin being driven out from the hall side of an outswing door; the security stud keeps the leaves interlocked even if the pin is removed. SEC security fasteners are also available if the screw heads are exposed. On any outswing exterior or corridor door in a building with public access, one of those is worth specifying.
6) Can I run power through the Ives 3CB1WT hinge for an electric lock?
Yes. It's available in electrified versions, TW4, TW8, and TW12 (four, eight, and twelve wire transfer), plus monitor options for door position sensing. Wire count is driven by what the lock and any monitoring need: a simple electric strike or electrified lock is usually satisfied by TW4, while a lock with request-to-exit and latch monitoring pushes you to TW8 or TW12. If you'd rather have a purpose-built energy transfer hinge, the Command Access ETH-CB70 is a medium duty 3 knuckle steel option, and the ETM-CB70 adds an integrated door position switch.
7) Is the Ives 3CB1WT hinge approved for a windstorm rated door assembly?
It's UL Classified for windstorm rated assemblies under R37965. It also exceeds ANSI/BHMA A156.1 performance requirements. For a windstorm opening, verify the full assembly listing covers your door, frame, and hardware set as a unit, since the classification applies to the assembly.
8) Can I use a plain bearing commercial hinge instead of the Ives 3CB1WT on a door with a closer?
The Ives 3CB1WT carries two concealed nylon bearings and is specifically recommended for use with door closers. Plain bearing commercial hinges such as the Orca Hardware 4040 Series 4 inch by 4 inch square corner hinge or the Orca 4014 Series 4 inch by 4 inch quarter-inch radius hinge are both rated medium duty, but they are plain bearing rather than bearing-equipped. If the opening has a closer, match the bearing type to what the closer load calls for rather than treating the duty rating alone as the equivalence.
9) What is the closest concealed bearing full mortise hinge to the Ives 3CB1WT if I need a wire transfer through the hinge?
The Ives 3CB1WT is a steel full mortise hinge with concealed bearings, rated medium duty, and it is offered with TW4, TW8 and TW12 electrification options. If you would rather buy the wire transfer as a catalog hinge rather than an option, the BEST CECB179-12C is a steel full mortise concealed bearing electrified hinge with a 12-wire quick connect and is also rated medium duty. Both land in the same duty class, so the choice is whether you want the conductor built into the base hinge or specified as an Ives option.
10) I want the non-removable pin security feature. Do I order the Ives 3CB1WT with NRP or a different hinge?
The Ives 3CB1WT is available with a non-removable pin (NRP) option, along with hospital tip (HT), security stud (SH) and security fasteners (SEC). If you prefer a hinge that carries NRP as its catalog identity, the Hager BB1168 is a non-removable pin full mortise ball bearing hinge rated heavy duty, and the Deltana CSB45N is a 4-1/2 inch by 4-1/2 inch square hinge pair supplied with a non-removable pin. The Hager moves you to ball bearing and heavy duty; the 3CB1WT keeps concealed bearings at medium duty with NRP specified as an option.
11) What looks like a substitute for the Ives 3CB1WT but is not?
Residential hinges are the usual mix-up. The Emtek 91013 is a residential plain bearing hinge pair, 3-1/2 inch by 3-1/2 inch with square corners in plated steel, and the Delaney 3-1/2 inch by 3-1/2 inch bulk steel residential hinges are interior residential stock with a 5/8 inch radius. Both share the square-corner or steel look, but the Ives 3CB1WT is a commercial hinge built to exceed ANSI/BHMA A156.1 and meet A156.7 template dimensions. If the door has to hold a template prep or a code-driven spec, the residential pairs will not carry it.
12) I need door position monitoring at the hinge. Is the Ives 3CB1WT the right hinge for that?
The Ives 3CB1WT is offered with monitor capability alongside its TW4, TW8 and TW12 electrification options. If you want the monitoring built into the hinge as its own model, the Command Access ETM-CB70 is an energy transfer monitor hinge with door position sensing on a 3 knuckle steel base, rated medium duty in the ETM 3 Series - the same knuckle count and duty class as the 3CB1WT. For a heavier leaf, the Command Access ETM-BB68 is an energy transfer monitor hinge with an integrated door position switch, rated heavy duty.
13) What hinge should I use instead of the Ives 3CB1WT on a detention or high-security opening?
The Ives 3CB1WT is a medium duty commercial hinge for doors up to 150 lbs; a detention opening is outside that. The BEST BB855 is a heavy-duty steel double weight concealed ball bearing prison hinge in the Detention Hardware series, and the Stanley Security BB855 is a double weight prison hinge, 5 inch by 6 inch, furnished with no holes and not swaged. The Hager 990 STEEL is a full surface prison hinge, 3 inch by 4 inch with a welded tip, rated heavy duty - note that is full surface rather than full mortise, so the frame and door prep is different from the 3CB1WT.
14) The frame will not take a full mortise hinge. What are my options against the Ives 3CB1WT?
The Ives 3CB1WT is a full mortise hinge, mortised into both the door and the frame. Where the frame cannot be mortised, the Hager 1129 is a half mortise plain bearing commercial hinge, 4-1/2 inch standard weight steel, rated heavy duty, which mortises into the door and applies to the frame face. For a door that must swing both ways, the BEST DAP-3 is a heavy duty double acting pivot for commercial interior doors and changes the hanging method entirely rather than substituting hinge for hinge.
15) Is there a concealed bearing concealed conductor hinge in 4-1/2 by 4-1/2 that I can spec instead of the Ives 3CB1WT?
The Ives 3CB1WT comes in 4.5 inch by 6 inch, 5 inch by 4.5 inch, 5 inch by 7 inch, 5 inch by 8 inch and 6 inch by 5 inch - the wide throw widths. For a 4-1/2 by 4-1/2 in the same three knuckle concealed bearing arrangement with a conductor, the Stanley Security CECB1900R54L is a three knuckle concealed bearing concealed conductor architectural hinge, steel full mortise, standard weight, 4-1/2 by 4-1/2, square corner, left-handed, 4-wire, rated heavy duty. It is handed, so confirm the swing before ordering; the 3CB1WT sizes are all wider throw than a 4-1/2 square.
16) I need the door to close itself without a closer. Does the Ives 3CB1WT do that?
No. The Ives 3CB1WT is a concealed bearing hinge recommended for use with door closers, meaning it is built to take the load a closer puts on the door, not to supply the closing force itself. If you need the hinge to do the closing, the Stanley Security 2060R is a spring hinge, full mortise, square corner, 4.5 inch by 4.5 inch on a ferrous steel base, rated heavy duty. Spring hinges and closer-rated hinges solve different halves of the same problem, so confirm which one your opening requires.
17) What sizes does the Ives 3CB1WT wide throw hinge come in?
Five: 4-1/2 x 6 inch, 5 x 4-1/2 inch, 5 x 7 inch, 5 x 8 inch, and 6 x 5 inch. Pick by how far you need the door to clear the frame and by the door leaf height, taller leaves for heavier or taller doors. The 5 x 7 and 5 x 8 give the most throw off the jamb.
18) What's the difference between a concealed bearing hinge and a ball bearing hinge?
On a concealed bearing hinge the bearings sit inside the knuckle where you can't see them, so the barrel reads as a clean 3 knuckle with no visible bearing rings. A ball bearing hinge shows the bearing races stacked between the knuckles. The 3CB1WT uses two concealed nylon bearings; the performance job is the same, carrying the load a closer puts on the door, but the look is cleaner and there's nothing exposed to collect grime. If the aesthetic doesn't matter, an exposed ball bearing hinge such as the Orca 3535 or Don-Jo HWBB75045 does the same duty.
19) I need to match hinges on the rest of my building. What finishes does the Ives 3CB1WT come in?
Twelve, and they cover the usual commercial standards plus the decorative ones: 600 primed for painting, 631 matte black, 632 bright brass, 633 satin brass, 639 satin bronze, 640 satin bronze dark, 641 oxidized bronze, 643E aged bronze, 646 satin nickel, 651 bright chrome, 652 satin chrome, and 695 dark bronze. If your other openings are on 652 satin chrome or 626 style hardware, 652 is the match. 600 primed lets you paint the hinge to the frame color.
20) Do I need a hospital tip hinge, and can I get one on the Ives 3CB1WT?
HT hospital tip is an option on it. The tip is angled instead of flat so gowns, IV lines, bedding, and mop strings can't catch on the top of the barrel. Specify it for patient room and corridor doors in healthcare, and it's common in senior living too. Everywhere else the standard tip is fine.
21) What's the residential equivalent, or is the Ives 3CB1WT overkill for an apartment interior door?
It's a commercial rated hinge, built for closer-equipped openings at 400 cycles a day. For an interior apartment door with no closer that's more hinge than the opening needs. Lighter options we carry include the Schlage Residential S3P1010 3.5 x 3.5 inch square corner plain bearing hinges in a pack of three, the Delaney RH35 3-1/2 x 3-1/2 inch bulk steel interior hinges sold in pairs, or Emtek 91013 residential plain bearing hinges. Keep the 3CB1WT for the corridor, stair, and entry doors where the closer is.
22) I do not need a wide throw hinge. What is the simpler concealed bearing option?
Wide throw on the Ives 3CB1WT buys extra clearance so the door can swing clear of trim or a deep jamb; if the opening does not need that clearance you are paying for width you will not use. The Hager 920 is a full mortise concealed plain bearing hinge in steel with 2-knuckle construction, rated medium duty, which is the same duty class in a standard throw. Note the knuckle count differs - the 3CB1WT is a 3 knuckle hinge - so the barrel appearance will not match if the two are hung on adjacent openings.
23) What is the difference between the Ives 3CB1WT and a 5 knuckle standard weight hinge like the McKinney MP79?
The Ives 3CB1WT is a 3 knuckle steel full mortise hinge with concealed bearings, rated medium duty. The McKinney MP79 MacPro is a full mortise hinge with 5 knuckles at standard weight, and the McKinney MPB79 is the same 5 knuckle standard weight MacPro configuration. The visible difference at the door is the barrel: three knuckles against five. Knuckle count is the thing to match if the hinge has to look like the others already hung in the corridor.
24) Is a ball bearing commercial hinge an equivalent to the Ives 3CB1WT for a medium duty opening?
They sit in the same duty class but the bearing is exposed differently. The Ives 3CB1WT uses two concealed nylon bearings, which keeps the bearing hidden inside the barrel. The Orca Hardware 3535 Series is a 4-1/2 inch by 4-1/2 inch square corner ball bearing commercial hinge rated medium duty, and the Delaney CH401X is a 4 inch by 4 inch commercial ball bearing hinge with square corners. All three are square corner commercial hinges; the concealed bearing on the Ives is the reason its barrel reads as a plain three-knuckle profile rather than showing bearing races between the knuckles.
25) For a non-ferrous or corrosion-prone opening, what replaces the steel Ives 3CB1WT?
The Ives 3CB1WT is built on a steel substrate. Where a ferrous base is not wanted, the McKinney T2314 is a non-ferrous hinge, standard weight, 5 knuckle, rated medium duty - the same duty class as the 3CB1WT but a different base material and a five knuckle barrel instead of three. Match the finish separately: the 3CB1WT is offered in finishes including 632 Bright Brass, 646 Satin Nickel and 652 Satin Chrome, and finish code alone does not tell you the base metal.
26) How many Ives 3CB1WT hinges do I need per door, and are they sold individually?
The 3CB1WT is a full mortise hinge sold per hinge, not in pairs, so order by the count of hinges the opening takes. Commercial doors up to 7 feet 6 inches normally take three hinges, and taller doors add one per additional 30 inches. Some of the comparable residential hinges we carry, like the Deltana DSB35 and the Delaney RH40, are sold as pairs instead, so watch the pack when you're comparing counts.
27) Where do I get the hinge template to lay out the door and frame prep?
Ives publishes a templates index covering its architectural hinges, and the full line catalog carries the model detail for the 3CB1WT. Pull the template before you rout, since the leaf sizes on this hinge run wide and the frame prep has to match the leaf you actually ordered, not a standard 4-1/2 x 4-1/2.
