Ives 3CB1HW 4.5x4.5 626 – Frequently Asked Questions

1) Will the Ives 3CB1HW hinge hold a heavy solid core or hollow metal door over 150 pounds?
That is exactly what the 3CB1HW is built for. It's a heavy weight full mortise hinge rated for doors over 150 pounds at up to 400 cycles per day, with two concealed nylon bearings carrying the load. If your door is under that weight and sees ordinary office traffic, a standard weight hinge does the job; heavy weight is what you specify when the door is thick solid core, lead lined, or a wide hollow metal leaf.
2) What size Ives 3CB1HW hinge do I need for my door?
Four sizes are made: 4.5 x 4, 4.5 x 4.5, 5 x 4.5, and 5 x 5 inches. The first number is hinge height, the second the open width. Pick height off door thickness and weight, and width off how far the door has to clear the trim or a return wall. A 1-3/4 inch commercial door normally takes a 4-1/2 inch hinge; go to 5 inch height on thicker or heavier leaves, and to the wider open width when the door needs to swing clear of deep casing.
3) Can I use the Ives 3CB1HW with a door closer on the opening?
Yes, and it's the recommended pairing. Ives calls out the 3CB1HW for use with door closers. A closer adds constant load and pull on the top hinge, which is why a concealed bearing heavy weight hinge is specified rather than a plain bearing one. Plain bearing hinges, like the Hager 920 concealed plain bearing or the Orca 4040 Series, are not the ones you want under a closer on a heavy leaf.
4) What do I need to order to keep the pin from being pulled on an out-swinging exterior door?
Specify the NRP option, non-removable pin, on the 3CB1HW. On any out-swing door the hinge barrel is on the unsecured side, so a standard pin can be driven out. NRP adds a set screw in the barrel that locks the pin in place once the door is closed. The SH security stud option is the other half of that problem: a stud on one leaf that engages the opposite leaf so the door can't be lifted out even if the pin is defeated.
5) I need to run power through the hinge to an electrified lock. Can the Ives 3CB1HW do it or do I need a different hinge?
The 3CB1HW offers electrification through its TW4, TW8, TW12 and MON options, so the electrified version is the same hinge with wires added. If you would rather use a purpose-built energy transfer hinge, the Command Access ETH-BB68 is a heavy duty 5-knuckle energy transfer hinge on a steel base in the ETH 5 series, and the Command Access ETM-BB68 is a heavy duty energy transfer monitor hinge with an integrated door position switch. For a factory-wired concealed bearing hinge, the Stanley CECB1900R54L is a three knuckle concealed bearing concealed conductor architectural hinge, steel full mortise, 4-1/2 x 4-1/2 square corner, left-handed, 4-wire, so it is handed and must be ordered to match the door swing.
6) What is the closest heavy weight full mortise hinge to the Ives 3CB1HW if I need square corners in a 4-1/2 x 4-1/2 size?
The Ives 3CB1HW is a heavy duty full mortise hinge with square corners and a concealed bearing, offered in 4.5 x 4.5 among its sizes. The closest heavy duty alternatives in full mortise form are the Don-Jo HWBB74545 heavy weight full mortise ball bearing hinge at 4-1/2 x 4-1/2 and the Don-Jo HWBB84545 heavy weight full mortise ball bearing hinge at the same 4-1/2 x 4-1/2 size. The difference is the bearing type: the 3CB1HW runs concealed bearings, while both Don-Jo models are ball bearing hinges with the bearings visible between the knuckles.
7) I need a heavy weight hinge in 5 x 4-1/2 for a closer-equipped door. What else covers that size besides the Ives 3CB1HW?
The Ives 3CB1HW covers 5 x 4.5 and is recommended for use with door closers. In the same size, the Don-Jo HWBB75045 is a heavy weight full mortise ball bearing hinge in 5 x 4-1/2 steel, and the Don-Jo HWBB85045 is a heavy weight full mortise ball bearing hinge in 5 x 4-1/2 brass. The 3CB1HW is offered in brass and stainless steel substrates, so if the job calls for a stainless base in that size the Ives is the one that carries it.
8) Is the Hager 920 concealed bearing hinge a substitute for the Ives 3CB1HW?
Both are full mortise concealed bearing hinges, but they are built for different openings. The Ives 3CB1HW is a heavy duty 3-knuckle hinge with two concealed nylon bearings, rated for doors over 150 pounds at 400 cycles per day. The Hager 920 is a medium duty full mortise concealed plain bearing hinge with 2-knuckle steel construction. If the door is heavy or runs a closer, the 920 is not an equal swap.
9) For a detention or high-security opening, is the Ives 3CB1HW with security studs enough or should I be looking at a prison hinge?
The 3CB1HW can be ordered with a security stud (SH), security fasteners (SEC) and a non-removable pin (NRP), which covers most commercial security openings. For a true detention application, the BEST BB855 is a heavy-duty steel double weight concealed ball bearing prison hinge in the detention hardware series, and the Stanley BB855 is a double weight prison hinge at 5 by 6 inches furnished with no holes and not swaged, meaning the frame and door prep is done in the field.
10) The door has no closer and needs to self-close. Does the Ives 3CB1HW handle that?
No. The Ives 3CB1HW is a concealed bearing hinge recommended for use with door closers, not a self-closing hinge. For a self-closing opening, the Stanley 2060R is a heavy duty spring hinge, full mortise, square corner, 4.5 x 4.5 on a ferrous steel base, which matches the 4.5 x 4.5 square corner prep the 3CB1HW also covers.
11) The frame is only prepped on one leaf, half mortise. Will the Ives 3CB1HW work?
No. The Ives 3CB1HW is a full mortise hinge, so both the door and the frame must be mortised. For a half mortise opening, the Hager 1129 is a half mortise plain bearing commercial hinge at 4-1/2 in standard weight steel and is rated heavy duty. Confirm which leaf is surface applied before ordering, since half mortise and full mortise preps are not interchangeable.
12) The opening is a double acting door that swings both ways. What do I use instead of the Ives 3CB1HW?
A full mortise hinge like the Ives 3CB1HW swings one direction only. For a door that swings both ways, the BEST DAP-3 is a heavy duty double acting pivot for commercial interior doors in the emergency rescue hardware series. Pivots carry the door on the top and bottom rather than on hinge leaves, so the door and frame prep is entirely different from a mortise hinge prep.
13) Do I get screws with the Ives 3CB1HW, and will they work on both wood and hollow metal doors?
Both sets ship with the hinge: 12-24 x 1/2 inch undercut flat head machine screws for hollow metal, and 12 x 1-1/4 inch flat head wood screws for wood doors and wood frames. So one part number covers a wood door in a hollow metal frame without a separate fastener order. If you're specifying tamper resistance, the SEC option supplies security fasteners instead.
14) Which finish of the Ives 3CB1HW should I use on an exterior or wet location door?
Go with 629 bright stainless or 630 satin stainless. Those two are the stainless steel substrate; every other finish (605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 614 oxidized bronze, 619 satin nickel, 625 bright chrome, 626 satin chrome) is a brass substrate. For a coastal, pool, kitchen, or exterior opening the stainless base is the one that resists corrosion, and 630 is the standard commercial match to most lever and exit hardware.
15) Is a 3 knuckle concealed bearing hinge better than a 5 knuckle ball bearing hinge for a heavy commercial door?
They solve the same problem differently. The 3CB1HW uses 3 knuckles with the nylon bearings hidden inside the barrel, so the hinge reads as a clean cylinder with no visible bearing rings, and grit stays out of the bearing. A 5 knuckle ball bearing hinge such as the Don-Jo HWBB84545 heavy weight full mortise puts exposed bearing races between the knuckles. Both carry heavy doors; concealed bearing is what gets specified when the appearance of the barrel matters or the opening is dirty, and ball bearing is the more common stock item.
16) Is the Ives 3CB1HW ANSI certified for commercial use?
It's certified to exceed ANSI/BHMA A156.1 and it meets A156.7 template hinge dimensions. A156.1 is the butt hinge performance standard, so that's the line a spec writer or facility standard is usually looking for on a commercial opening. It's a commercial duty product, not a residential one.
17) Is the Ives 3CB1HW overkill for a 3-1/2 inch residential interior door?
Yes, it's the wrong part for that. The 3CB1HW starts at 4-1/2 inch height and is a commercial heavy weight hinge for doors over 150 pounds. A standard 1-3/8 inch interior residential door takes a 3-1/2 inch hinge. For that opening look at the Deltana DSB35 3-1/2 x 3-1/2 square hinge or the Emtek 91013 residential plain bearing pair, both 3-1/2 inch square corner.
18) Does the Ives 3CB1HW come handed, or is one hinge good for either swing?
A full mortise butt hinge like the 3CB1HW is non-handed in its standard form: the same hinge works on a left or right hand door, you just flip it. Handing only enters the picture on the electrified versions, where the wire has to exit toward the correct side of the frame. If you're ordering TW4, TW8, TW12, or MON, confirm the door hand with the order.
19) The opening needs a non-removable pin hinge out of the box. Is there a heavy duty option other than ordering the Ives 3CB1HW with NRP?
The 3CB1HW is available with a non-removable pin as an NRP option. If you would rather order a part that is already configured that way, the Hager BB1168 is a non-removable pin full mortise ball bearing heavy duty hinge in the BB1168 series. It is a ball bearing hinge rather than a concealed bearing one, so the knuckle appearance differs from the Ives.
20) Do I need the Ives 3CB1HW for a standard interior office door, or is there a lighter hinge that fits?
The Ives 3CB1HW is a heavy duty commercial hinge built for doors over 150 pounds at 400 cycles per day. For an interior door that does not carry that weight or traffic, medium duty commercial hinges cover the same full mortise cutout family: the Orca Hardware 3535 series is a 4-1/2 x 4-1/2 square corner ball bearing commercial hinge, and the Orca Hardware 4040 series is a 4 x 4 square corner plain bearing commercial hinge. Match the size to the existing frame prep before switching.
21) What should I use instead of the Ives 3CB1HW when the door needs radius corners instead of square?
The 3CB1HW is a square corner hinge, and rounded corners are handled through its RC-1/4 and RC-5/8 options. If the frame prep already calls for a radiused hinge as the base part, the Orca Hardware 3514 series is a 3.5 x 3.5 x 1/4 inch radius corner plain bearing commercial hinge and the Orca Hardware 4014 series is a 4 x 4 x 1/4 inch radius corner plain bearing commercial hinge. Both are medium duty and plain bearing, so confirm the door weight and closer before substituting.
22) What is the difference between the Ives 3CB1HW and the Stanley FBB191 for a commercial door?
Knuckle count and bearing style separate them. The Ives 3CB1HW is a 3-knuckle concealed bearing hinge with heavy duty rating and square corners. The Stanley FBB191 is a 5-knuckle full mortise standard weight hinge at 4.5 x 4.5. The FBB191 shows a five-knuckle barrel, while the 3CB1HW shows three knuckles with the bearings hidden inside, which matters if you are matching the look of hinges already hung on adjacent doors.
23) Is the McKinney MacPro MP79 an equivalent to the Ives 3CB1HW?
They are not equivalent. The Ives 3CB1HW is a heavy duty 3-knuckle concealed bearing hinge for doors over 150 pounds. The McKinney MP79 MacPro is a full mortise 5-knuckle standard weight hinge, and the MPB79 MacPro is likewise a 5-knuckle standard weight hinge. Standard weight leaves are intended for lighter doors, so the MacPro pair suits a different opening than the 3CB1HW.
24) How many Ives 3CB1HW hinges do I need per door, and are they sold individually?
The 3CB1HW is ordered as a single hinge by size and finish, not as a pair. Standard practice on a commercial opening is three hinges for a door up to 7 feet 6 inches, and a fourth added for taller leaves; heavy doors with a closer are the case where you do not skimp to two. Note the difference from several residential lines, such as the Deltana DSB3 or Delaney exterior residential hinges, which are packaged as pairs.
