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

1) Will the Ives 5PB1 hinge hold up on a busy commercial entrance or classroom door?
The 5PB1 is a plain bearing hinge built for standard weight doors in low frequency openings, and it is rated Grade 2 medium duty at 1,500,000 cycles. That suits offices, storerooms, and interior doors that see moderate traffic. For a main entrance, a heavy stairwell door, or anything with a closer pulling on it all day, step up to a heavy weight ball bearing hinge such as the Don-Jo HWBB84545 in 4-1/2 x 4-1/2 or the Hager BB1168. Plain bearing hinges wear faster under a closer than ball bearing hinges do.
2) What sizes does the Ives 5PB1 full mortise hinge come in?
Five sizes: 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. The 4-1/2 x 4-1/2 is the usual pick for a 1-3/4 inch commercial door; 3-1/2 x 3-1/2 matches lighter 1-3/8 inch interior doors. The 4-1/2 x 4 and 5 x 4-1/2 sizes exist because leaf width has to match the door thickness plus any trim clearance, so measure the existing hinge before you order rather than guessing from door height.
3) Will the Ives 5PB1 drop into the hinge pockets already cut in my frame?
It meets ANSI/BHMA A156.7 template dimensions, so the leaf pattern and screw hole layout match any other hinge cut to that same template in the same size. If the existing hinges are square corner and the same size, the 5PB1 goes back in without re-routing. Check corner style first: the 5PB1 is square corner as standard, and a 1/4 inch or 5/8 inch radius pocket needs the RC-1/4 or RC-5/8 option instead.
4) How do I keep someone from pulling the hinge pin on an out-swinging door?
Specify the 5PB1 with the NRP non-removable pin option, or with the SH security stud, on any door that swings out into a public corridor or to the exterior. The pin side is exposed on an out-swing, and NRP sets a set screw that captures the pin while SH adds an interlocking stud so the leaves stay engaged even if the pin comes out. SEC security fasteners are also available if the screw heads are reachable.
5) Can the Ives 5PB1 be used on a door that needs power transferred to the lock?
The Ives 5PB1 is a mechanical plain bearing hinge with no electrical provision, so an opening that carries power to an electrified lock or an exit device needs an energy transfer hinge in one of the hinge positions. The Command Access ETH-CB70 is a 3 knuckle standard weight steel base energy transfer hinge at medium duty, matching the 5PB1's medium duty rating, and the ETH-BB68 is the 5 knuckle heavy duty version. If the opening also needs door position monitoring, the Command Access ETM-CB70 adds door position sensing in a 3 knuckle steel base at medium duty, and the ETM-BB68 does the same in a heavy duty 5 knuckle. The BEST CECB179-12C is a steel full mortise concealed bearing electrified hinge with a 12-wire quick connect at medium duty. Typically only one hinge per opening is the transfer hinge; the rest can remain 5PB1.
6) What is the closest equivalent to the Ives 5PB1 hinge from another brand?
The Ives 5PB1 is a plain bearing full mortise hinge with a 5 knuckle barrel, square corners, and medium duty commercial rating in brass or stainless steel. The closest peers are the Orca Hardware 4040 Series 4 inch by 4 inch square corner plain bearing commercial hinge and the Schlage Residential S3P1010 3-1/2 inch by 3-1/2 inch square corner plain bearing mortise hinge, both medium duty plain bearing hinges with square corners. The Orca 4040 matches the 4 inch by 4 inch size the 5PB1 offers, and the Schlage S3P1010 matches the 3-1/2 inch by 3-1/2 inch size and ships as a pack of 3. Where the 5PB1 differs is substrate: it is brass or stainless steel across 10 finishes from 605 bright brass through 630 satin stainless steel.
7) The exterior door needs a hinge with a non-removable pin. What matches the Ives 5PB1 prep?
The Ives 5PB1 can be ordered with the non-removable pin (NRP) option, along with a security stud (SH) and security fasteners (SEC), so an out-swinging exterior door can stay on the 5PB1 with the correct suffix. If a different construction is wanted, the Deltana CSB45N is a 4-1/2 inch by 4-1/2 inch square hinge with a non-removable pin sold in pairs, matching the square corner prep the 5PB1 uses. The Hager BB1168 is a heavy duty full mortise ball bearing hinge with a non-removable pin, and the Deltana DE44R5TA is a 4 inch by 4 inch security steel hinge in 5/8 inch radius, which requires a radius corner prep rather than a square one.
8) The door is heavy and gets constant traffic. What should be used instead of the Ives 5PB1?
The Ives 5PB1 is a Grade 2 medium duty plain bearing hinge intended for standard weight doors in low frequency use. A heavy door on a high traffic opening calls for a heavy weight ball bearing hinge instead. The Don-Jo HWBB74545 is a heavy duty heavy weight full mortise ball bearing hinge in 4-1/2 inch by 4-1/2 inch, and the Don-Jo HWBB75045 is the same construction in 5 inch by 4-1/2 inch. The Hager BB1168 is a heavy duty full mortise ball bearing hinge furnished with a non-removable pin. In square corner medium duty ball bearing, the Orca 3535 Series is 4-1/2 inch by 4-1/2 inch.
9) The frame is prepped for a half mortise hinge. Will the Ives 5PB1 work?
No. The Ives 5PB1 is a full mortise hinge, meaning both leaves mortise into the door and the frame. A frame prepped for half mortise needs the Hager 1129, a half mortise plain bearing commercial hinge in 4-1/2 inch standard weight steel at heavy duty. If the opening is prepped for full surface instead, the Hager 990 STEEL is a full surface prison hinge in 3 inch by 4 inch with a welded tip at heavy duty. Both keep plain bearing operation; only the mounting method changes.
10) Which hinge should be used on a door that has to self-close without a closer?
The Ives 5PB1 is a plain bearing hinge with no spring, so it will not return a door on its own. A self-closing opening needs a spring hinge: the Stanley 2060R is a full mortise spring hinge with square corners in 4-1/2 inch by 4-1/2 inch on a ferrous steel base at heavy duty. The square corner and 4-1/2 inch by 4-1/2 inch size line up with the square corner prep and the 4.5 inch by 4.5 inch size the 5PB1 covers, so the frame prep carries over. For a door that must swing both directions, the BEST DAP-3 is a heavy duty double acting pivot for commercial interior doors, which replaces hinges entirely rather than substituting for them.
11) Is the Ives 5PB1 suitable for a detention or behavioral health opening?
No. The Ives 5PB1 is a Grade 2 medium duty commercial hinge for standard weight doors, which is below what a detention opening demands, though it can be ordered with a non-removable pin (NRP), security stud (SH), hospital tip (HT), and security fasteners (SEC) for openings that need tamper resistance short of detention grade. For true detention work, the BEST BB855 is a heavy-duty steel double weight concealed ball bearing prison hinge, and the Stanley BB855 is a double weight prison hinge in 5 inch by 6 inch furnished with no holes and not swaged. The Hager 990 STEEL is a heavy duty full surface prison hinge in 3 inch by 4 inch with a welded tip.
12) Which Ives 5PB1 finishes are stainless steel and which are brass?
Finish decides the base metal. 629 bright stainless and 630 satin stainless are stainless steel substrate; every other finish, 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil-rubbed satin bronze, 614 oxidized bronze, 619 satin nickel, 625 bright chrome, and 626 satin chrome, is brass substrate. That matters on exterior or wash-down openings, where 630 stainless is the one to specify.
13) Can I use the Ives 5PB1 hinge on a psychiatric or behavioral health unit door?
Order it with the HT hospital tip. The hospital tip slopes the top of the barrel so there is no flat ledge to loop a ligature or a strap over, which is what behavioral health and detention-adjacent openings call for. If the door itself is a detention opening, the 5PB1 is the wrong weight class entirely, and a purpose-built prison hinge such as the BEST BB855 or the Stanley 5 x 6 double weight prison hinge is what belongs there.
14) Is the Ives 5PB1 a commercial hinge or a residential one?
Commercial. It is certified to exceed ANSI/BHMA A156.1 and carries a Grade 2 rating, which is the standard architects write into a hardware schedule for offices, schools, healthcare, retail, and multi-tenant buildings. Residential-grade hinges like the Delaney bulk interior hinges or the Emtek 91013 residential plain bearing pair are not written to that standard and will not satisfy a commercial spec.
15) Can I standardize a whole building on the Ives 5PB1 hinge?
For standard weight interior openings, yes, and that is what the five knuckle full mortise pattern and the ANSI/BHMA A156.7 template make possible: one hinge, one prep, ten finishes to match whatever lever and closer trim is already on the doors. What it will not cover is the exceptions. Entrances and closer-equipped doors need a heavier ball bearing hinge, access-controlled doors need an electric through-wire hinge, and out-swinging exterior doors need the NRP or SH option on the same 5PB1.
16) Is the Ives 5PB1 a full mortise hinge that mortises into both the door and the frame?
Yes, both. Full mortise means each leaf sits in a routed pocket, one in the door edge and one in the frame rabbet, so the hinge is flush and only the barrel shows when the door is closed. If your frame is a channel or the door edge cannot be routed, a full mortise hinge is the wrong style, and a half mortise hinge like the Hager 1129 4-1/2 inch standard weight or a full surface hinge is what fits that condition.
17) What is the difference between the Ives 5PB1 and a concealed bearing hinge like the Hager 920?
The Ives 5PB1 carries its load on a plain bearing between five knuckles, and the barrel is visible on the door edge. The Hager 920 is a full mortise concealed plain bearing hinge with a 2 knuckle steel construction at medium duty, which puts the bearing out of sight and gives a different barrel appearance. Both are medium duty full mortise. Other concealed bearing options include the BEST CB1969R, a concealed bearing heavy weight pivot-reinforced hinge at heavy duty, and the Stanley CECB1900R54L, a three knuckle concealed bearing concealed conductor architectural hinge in steel full mortise, standard weight, 4-1/2 inch by 4-1/2 inch, square corner, left-handed with 4 wires. For a decorative 2 knuckle barrel with no bearing concealment, the McKinney SQ3331 is a square barrel 2-knuckle decorative hinge in 4-1/2 inch by 4-1/2 inch.
18) Is the Emtek 92013 hinge the same thing as an Ives 5PB1?
Both are plain bearing hinges with square corners, but they are built for different openings. The Emtek 92013 is a heavy duty plain bearing hinge sold as a pair in 3-1/2 inch by 3-1/2 inch with a plated steel base. The Ives 5PB1 is a commercial Grade 2 medium duty hinge with a brass or stainless steel substrate, a 5 knuckle barrel, and sizes from 3-1/2 inch by 3-1/2 inch up to 5 inch by 4-1/2 inch. Emtek also builds the 91013, a residential duty plain bearing hinge in the same 3-1/2 inch by 3-1/2 inch square corner plated steel format. If the specification calls for a non-ferrous or stainless barrel and ANSI/BHMA A156.1 certification, the 5PB1 is the one that carries it.
19) What is a lower cost hinge for interior residential doors where the Ives 5PB1 is more than the job needs?
The Ives 5PB1 is a commercial Grade 2 hinge certified to ANSI/BHMA A156.1, which is more hinge than an interior residential door usually calls for. For interior residential work, the Delaney RH35xx is a bulk steel residential interior hinge in 3-1/2 inch by 3-1/2 inch with a 5/8 inch radius, sold in pairs, and the Delaney RH45xx is a bulk residential exterior hinge in 4 inch by 4 inch with a 5/8 inch radius. In square corner, the Deltana DSB35 is a 3-1/2 inch by 3-1/2 inch residential square hinge sold in pairs and the DSB3 is the 3 inch by 3 inch. Note the Delaney units are radius corner, so they will not drop into a square corner prep the way the 5PB1 does.
20) What 5 knuckle full mortise standard weight hinges compare to the Ives 5PB1?
The Ives 5PB1 is a 5 knuckle full mortise hinge for standard weight doors, medium duty, square corner, in brass or stainless steel. Comparable 5 knuckle standard weight units include the McKinney MP79 MacPro full mortise hinge and the McKinney MPB79 MacPro, both 5 knuckle standard weight at standard duty, and the McKinney T2314 non-ferrous 5 knuckle standard weight hinge at medium duty, which is the nearest match on both knuckle count and non-ferrous substrate. The Stanley FBB191 is a 5 knuckle full mortise standard weight hinge in 4-1/2 inch by 4-1/2 inch at heavy duty. The Command Access ETH-BB68 is also a 5 knuckle unit, but it is an energy transfer hinge on a heavy duty steel base rather than a straight mechanical hinge.
21) Can a ball bearing hinge be mixed with the Ives 5PB1 on the same frame prep?
The Ives 5PB1 is a plain bearing hinge with square corners, so a ball bearing replacement has to match the corner style and size to reuse the existing prep. The Orca 3535 Series is a 4-1/2 inch by 4-1/2 inch square corner ball bearing commercial hinge at medium duty, matching the 5PB1's square corner and its 4.5 inch by 4.5 inch size. The Delaney CH401X is a 4 inch by 4 inch commercial ball bearing hinge with a square corner, matching the 4 inch by 4 inch size. The Emtek 94013 is a heavy duty ball bearing hinge sold in pairs, 3-1/2 inch by 3-1/2 inch with square corners in plated steel. Ball bearing units run at higher cycle duty than plain bearing, which is what changes when the hinge is swapped.
