Ives 3PB1 4.5x4.5 626 – Frequently Asked Questions

1) Is the Ives 3PB1 hinge heavy enough for a high-traffic commercial door?
The 3PB1 is a plain bearing hinge built for standard weight doors in low frequency openings, and it is rated Grade 2 to 1,500,000 cycles. That covers offices, classrooms, storerooms, and tenant entries that see moderate use. For an exterior entry, a heavily used restroom, or any door with a closer on it, step up to a ball bearing hinge instead. A plain bearing knuckle carries the load metal on metal, so a door that swings all day will wear it faster than a bearing hinge.
2) What sizes does the Ives 3PB1 full mortise hinge come in?
Five sizes cover the range: 3-1/2 x 3-1/2, 4 x 4, 4-1/2 x 4, 4-1/2 x 4-1/2, and 5 x 4-1/2 inches. Match the leaf height to the door you are hanging (3-1/2 and 4 inch for lighter interior doors, 4-1/2 and 5 inch for standard commercial openings), and match the width to your existing mortise so you are not re-routing the jamb. The 4-1/2 x 4 is the one to look at when the frame is prepped for a 4-1/2 inch leaf but the door is thinner than standard.
3) Will the Ives 3PB1 drop into my existing hinge mortise without re-routing?
It meets ANSI/BHMA A156.7 template hinge dimensions, so the screw hole pattern and leaf geometry match any other template hinge of the same size. If the door and frame are already prepped for a template hinge, pick the matching size and it lands on the existing holes. The corners are square, so if your current mortise has a radiused corner (1/4 or 5/8 inch), you either need the rounded corner option (RC-1/4 or RC-5/8) or you will be chiseling the corners out square.
4) Which Ives 3PB1 finishes are brass and which are stainless steel?
The substrate follows the finish. Finishes 629 (bright stainless steel) and 630 (satin stainless steel) are stainless steel; every other finish is brass. So if you need stainless for a coastal, wash-down, or corrosive environment, you have to order 629 or 630, not a plated brass finish. The full finish list is 605 bright brass, 606 satin brass, 612 satin bronze, 613 satin bronze oil-rubbed, 614 oxidized bronze, 619 satin nickel, 622 matte black, 625 bright chrome, 626 satin chrome, 629, 630, 643E aged bronze, and 695 dark bronze.
5) How do I stop someone pulling the hinge pin on an outswing door with these hinges?
Order the 3PB1 with the non-removable pin option (NRP) or the security stud option (SH). NRP sets a screw into the barrel so the pin cannot be driven out, and the security stud puts an interlocking pin on one leaf that engages the other, so the door stays in the frame even if the pin is defeated. Security fasteners (SEC) are also available if you want the screw heads tamper resistant on the same order. This matters on any door that swings out, since the barrel is on the exterior side.
6) The door is a high traffic entrance with a closer. What should be specified instead of the Ives 3PB1?
The 3PB1 is a plain bearing hinge rated medium duty and built for standard weight doors in low frequency usage. An opening that cycles constantly or carries a closer is better served by a ball bearing hinge. The Orca Hardware 3535 Series is a 4-1/2 inch by 4-1/2 inch square corner ball bearing commercial hinge at medium duty, keeping the square corner prep. For a heavier door, the Don-Jo HWBB74545 and HWBB84545 are heavy duty full mortise ball bearing hinges at 4-1/2 inch by 4-1/2 inch, and the HWBB75045 and HWBB85045 cover 5 inch by 4-1/2 inch.
7) The door needs to carry power to an electrified lock. Which hinge takes the place of the Ives 3PB1?
The Ives 3PB1 is a plain bearing mechanical hinge with no wire path through the leaf, so a powered opening needs a transfer hinge. The Command Access ETH-CB70 is a 3 knuckle standard weight steel base energy transfer hinge at medium duty, matching the 3PB1 3 knuckle configuration. If the opening also needs door position monitoring, the Command Access ETM-CB70 adds door position sensing on the same 3 knuckle steel base at medium duty. The BEST CECB179-12C is a steel full mortise concealed bearing electrified hinge with a 12-wire quick connect at medium duty, for openings that need more conductors.
8) What is the closest commercial equivalent to the Ives 3PB1 plain bearing full mortise hinge in a 4 inch by 4 inch square corner size?
The Orca Hardware 4040 Series is a 4 inch by 4 inch square corner plain bearing commercial hinge at medium duty, which matches the 3PB1 on bearing type, corner style, and duty level. The 3PB1 is a plain bearing full mortise hinge with square corners, medium duty, and it lists 4 inch by 4 inch among its sizes. The main difference is substrate: the 3PB1 is offered in brass and stainless steel, so if the opening calls for a 626 satin chrome or 630 satin stainless finish to match adjacent hardware, the 3PB1 finish range is the reason to stay with it.
9) Does the Ives 3PB1 close the door on its own like a spring hinge?
No. The 3PB1 is a plain bearing full mortise hinge with no self-closing mechanism. For an opening that has to self-close without a surface closer, the Stanley Security 2060R is a full mortise spring hinge with square corners at 4.5 inch by 4.5 inch on a ferrous steel base, rated heavy duty. That square corner and 4.5 inch by 4.5 inch size matches a prep the 3PB1 also covers, so a door already hung on 3PB1 hinges at that size can take spring hinges without new routing.
10) Is the Ives 3PB1 suitable for a detention or behavioral health opening?
No. The 3PB1 is a medium duty plain bearing hinge for standard weight doors in low frequency usage. Detention openings call for purpose-built hardware: the BEST BB855 is a heavy-duty steel double weight concealed ball bearing prison hinge, the Stanley BB855 is a double weight prison hinge at 5 inch by 6 inch furnished with no holes and not swaged, and the Hager 990 STEEL is a full surface prison hinge at 3 inch by 4 inch with a welded tip, heavy duty. Note the Hager 990 is full surface, not full mortise like the 3PB1, so it applies to the face of door and frame rather than into a mortise.
11) The door has to swing both directions. Will the Ives 3PB1 work?
No. The 3PB1 is a full mortise hinge for a single direction swing. A door that swings both ways needs a double acting pivot such as the BEST DAP-3, a heavy duty double acting pivot for commercial interior doors. That is a pivot set, not a mortise hinge, so the door and floor prep are different from a hinge prep entirely.
12) Which plain bearing hinges are certified to ANSI/BHMA A156.1 for a facility standardization spec?
The Ives 3PB1 is certified to exceed ANSI/BHMA A156.1 and meets ANSI/BHMA 156.7 template hinge dimensions, at Grade 2 with a 1,500,000 cycle rating, and is UL Classified for windstorm rated assemblies under R37965. It is offered in 13 finishes from 605 bright brass through 630 satin stainless steel and 695 dark bronze, across sizes from 3-1/2 inch by 3-1/2 inch to 5 inch by 4-1/2 inch, which is what lets one part number cover a mixed door schedule. Among plain bearing peers, the Orca 4040 and 4014 Series and the Schlage S3P1010 are commercial and residential plain bearing hinges respectively, and the Emtek 91013 is a residential duty plain bearing hinge.
13) Do I need to order screws separately for the Ives 3PB1 hinge?
No. Each 3PB1 ships with both machine and wood screws, so it covers a hollow metal frame and a wood door out of the same box: 12-24 x 1/2 inch and 10-24 x 1/2 inch undercut flat head machine screws, plus 12 x 1-1/4 inch and 10 x 1 inch flat head wood screws. Nothing else is required to hang it on a standard prepped opening.
14) Is the Ives 3PB1 hinge OK for a behavioral health or psychiatric patient room door?
Specify the hospital tip option (HT) on the 3PB1. The hospital tip replaces the flat button tip with an angled one so there is no ledge to tie a ligature to or catch clothing on, which is what healthcare and behavioral health specs call for. It is a factory option, so it has to be on the order; a standard tip hinge cannot be converted in the field.
15) Can I use the Ives 3PB1 on a windstorm rated door assembly?
Yes, the 3PB1 is UL Classified for windstorm rated assemblies under file R37965. That covers storm shelter and hurricane opening work where the hinge has to be part of a listed assembly, which is the usual sticking point on school and municipal projects in coastal jurisdictions.
16) What is the closest alternative to the Ives 3PB1 if I need the same plain bearing hinge in a radius corner?
The 3PB1 is square corner only in its standard form. For a radiused mortise, the Orca Hardware 4014 Series is a 4 x 4 with a 1/4 inch radius corner plain bearing commercial hinge, and the Orca 3514 Series is the same thing in 3-1/2 x 3-1/2. Both are medium duty plain bearing like the 3PB1. If you want to stay with Ives, the 3PB1 can be ordered with the RC-1/4 or RC-5/8 rounded corner option instead.
17) Will the Ives 3PB1 match the other hinges already hung in my building?
Match on three things and it will: size, finish, and corner style. The 3PB1 comes in 3-1/2 x 3-1/2 through 5 x 4-1/2 and in 21 ANSI/BHMA listed finishes, with 13 finish choices offered here including 626 satin chrome and 630 satin stainless, the two most common on commercial openings. It is a 3-knuckle barrel, so alongside a 5-knuckle hinge on an adjacent door the barrel will read slightly different up close even in the same finish. Same door, mixed hinges, is where you would notice it.
18) Is the Hager 920 concealed bearing hinge the same as the Ives 3PB1 plain bearing hinge?
They are different bearing designs and different knuckle counts. The Hager 920 is a full mortise concealed bearing hinge with 2 knuckle steel construction at medium duty. The Ives 3PB1 is a plain bearing full mortise hinge with 3 knuckles in brass or stainless steel substrate. Both are full mortise and both are medium duty, but the visible barrel differs: a 2 knuckle barrel and a 3 knuckle barrel will not look alike side by side on adjacent doors, which matters when matching a fleet.
19) What non-ferrous or 5 knuckle alternatives exist to the Ives 3PB1 for a full mortise standard weight opening?
The Ives 3PB1 is a 3 knuckle hinge. If the specification calls for a 5 knuckle barrel, the McKinney T2314 is a non ferrous 5 knuckle standard weight hinge at medium duty, which is the closest match on weight class. The McKinney MP79 and MPB79 MacPro hinges are also 5 knuckle standard weight at standard duty. Non ferrous matters on exterior or coastal openings where a steel base hinge is a corrosion concern; the 3PB1 answers that with a brass or stainless steel substrate, with 629 and 630 being the stainless finishes.
20) The Ives 3PB1 is available with a non-removable pin. What other hinges offer NRP for an out-swinging exterior door?
The 3PB1 can be ordered with a non-removable pin (NRP), along with hospital tip, security stud, and security fasteners. Among comparable hinges, the Hager BB1168 is a non-removable pin full mortise ball bearing heavy duty hinge, and the Deltana CSB45N is a 4-1/2 inch by 4-1/2 inch square hinge pair with a non-removable pin. The Deltana DE44R5TA is a 4 inch by 4 inch security hinge in steel with a 5/8 inch radius. Where the opening is an out-swing and the pin is reachable from the exterior, any of these blocks pin removal; the 3PB1 does it while keeping plain bearing construction and the brass or stainless substrate.
21) What is the difference between the Ives 3PB1 and the Delaney CH401X commercial ball bearing hinge?
The Delaney CH401X is a 4 inch by 4 inch commercial ball bearing hinge with square corners. The Ives 3PB1 at 4 inch by 4 inch shares the square corner and the leaf size, but uses plain bearing construction rather than ball bearing, and is rated medium duty with ANSI/BHMA A156.1 Grade 2 certification. Ball bearing construction is the usual choice where door weight or cycle frequency is higher; plain bearing suits standard weight doors in low frequency usage.
22) Which hinge should be used instead of the Ives 3PB1 on a heavy or pivot-reinforced door leaf?
The 3PB1 is built for standard weight doors and is rated medium duty, so a heavy leaf calls for a different hinge. The BEST CB1969R is a concealed bearing heavy weight pivot-reinforced hinge at heavy duty. The Stanley FBB191 is a 5-knuckle full mortise standard weight hinge at 4.5 inch by 4.5 inch rated heavy duty, which keeps the full mortise prep at a size the 3PB1 also covers. Confirm the door weight against the hinge weight class before ordering.
