Ives 1021RP F 626E – Frequently Asked Questions

1) Will the Ives 1021RP 4 x 4 hinges work on a heavy solid-core entry door?
No. The Ives 1021 plain bearing hinge is sized for doors under 70 lbs that don't exceed 3'0" x 7'0". A heavy solid core slab, a fire door, or anything wider than 3 feet needs a ball bearing or heavy weight hinge instead. From what ZenSupply carries, the Don-Jo HWBB74545 is a heavy weight full mortise ball bearing hinge at 4-1/2" x 4-1/2", and the Orca 3535 Series is a 4-1/2" x 4-1/2" square corner ball bearing commercial hinge. Both step up from plain bearing to bearing-equipped for the extra weight and traffic.
2) Will Ives 1021RP hinges drop into my existing 4 inch hinge pockets with 5/8 radius corners?
If the existing pocket is a 4" x 4" mortise with 5/8" radius corners, yes. The 1021 is a 4" x 4" full mortise hinge with 5/8" radius corners and meets ANSI/BHMA 156.7 template hinge dimensions, so the leaf and screw hole pattern match a standard template prep. Square corner pockets are the one to watch: a radius corner leaf in a square routed pocket leaves a visible gap at each corner. Measure the corner radius on the old hinge before you order.
3) What is the difference between a plain bearing hinge and a ball bearing hinge, and which do I need?
Plain bearing means the knuckles ride directly on each other with no bearing race between them. The Ives 1021 is plain bearing, Grade 3, rated 350,000 cycles, which suits doors that open a few dozen times a day: apartment interiors, offices, bedrooms, closets. Ball bearing hinges put a bearing between the knuckles so they carry more weight and take far more cycles without binding, which is what you want on a main entry, a stairwell, or anything with a closer on it. If the door has a door closer, go ball bearing. ZenSupply carries the Orca 3535 Series 4-1/2" ball bearing commercial hinge and the Delaney CH401X 4" x 4" commercial ball bearing square corner hinge for that duty.
4) Can I take the door off without unscrewing the Ives 1021RP hinges?
Yes. The 1021RP uses button non-rising pins with caps, so you pull the pin and lift the leaf off without touching a single screw. That is what property managers want for unit turns, painting, and moving appliances through a doorway. It also means the pin is removable from the hinge, so on an out-swinging exterior door where the barrel is on the outside, this is the wrong choice. Use a non-removable pin hinge there, such as the Deltana CSB45N 4-1/2" square NRP hinge or the Hager BB1168 NRP full mortise hinge.
5) The opening needs power to an electric lock through the hinge - can the Ives 1021RP be used?
No. The Ives 1021RP is a plain bearing hinge with a button non-rising pin and no wire path through the barrel. For transferring power from frame to door you need an electrified hinge: the Command Access ETH-CB70 is a 3 knuckle standard weight steel base energy transfer hinge in medium duty, the Command Access ETH-BB68 is the heavy duty 5 knuckle version, and the BEST CECB179-12C is a steel full mortise concealed bearing electrified hinge with a 12 wire quick connect for higher wire counts. If the opening also has to report whether the door is closed, the Command Access ETM-CB70 adds door position sensing on a 3 knuckle steel base and the ETM-BB68 pairs an integrated door position switch with a heavy duty body. Wire count has to match what the lock and access control panel need.
6) What is the closest 4 inch by 4 inch plain bearing commercial hinge to the Ives 1021RP if a square corner door prep is already routed?
The Ives 1021RP is a 4" x 4" steel plain bearing full mortise hinge with 5/8" radius corners, so it drops into a radius-routed prep. For a square corner prep at the same size and bearing type, the Orca Hardware 4" x 4" Square Corner Plain Bearing Commercial Hinge covers the same 4 inch by 4 inch footprint with square corners instead. Corner style has to match the mortise the router cut - a radius corner hinge in a square prep leaves a gap at each corner, and a square corner hinge in a radius prep will not seat without chiseling.
7) The frame prep is 4 inch by 4 inch with a 1/4 inch radius, not 5/8 inch - what plain bearing hinge fits that?
The Orca Hardware 4" x 4" x 1/4" Radius Corner Plain Bearing Commercial Hinge is the 1/4 inch radius version at the same 4 inch by 4 inch size and the same plain bearing action as the Ives 1021RP, which is cut for 5/8" radius corners. Radius size is not interchangeable: 5/8 inch and 1/4 inch corners are different arcs, and mixing them across doors in the same building means two different frame preps.
8) Door openings are 3-1/2 inch hinges, not 4 inch - what plain bearing hinge matches the Ives 1021RP at the smaller size?
The Ives 1021RP is a 4" x 4" hinge. At 3-1/2 inch, the Schlage Residential S3P1010 3.5" x 3.5" Square Corner Plain Bearing Mortise Hinge comes three to a pack like the Ives set of three and is also a 1000 Series plain bearing mortise hinge, though with square corners. The Emtek 91013 is a 3-1/2" x 3-1/2" plain bearing hinge with square corners in plated steel, sold as a pair. The Orca Hardware 3.5" x 3.5" x 1/4" Radius Corner Plain Bearing Commercial Hinge is the radius corner option at that size. Hinge size follows the door thickness and width the frame was prepped for, so measure the existing leaf before dropping from 4 inch to 3-1/2 inch.
9) The doors are heavier than 70 lbs and see constant traffic - what should be used instead of the Ives 1021RP?
The Ives 1021RP is a medium duty plain bearing hinge recommended for doors under 70 lbs and no larger than 3'0" x 7'0". For heavier leaves and higher cycle counts, ball bearing heavy duty hinges are the usual move: the Don-Jo HWBB74545 is a heavy weight full mortise ball bearing hinge at 4-1/2" x 4-1/2", the Don-Jo HWBB75045 is the same heavy weight ball bearing build at 5" x 4-1/2" for wider or heavier doors, and the Hager BB1168 is a heavy duty full mortise ball bearing hinge with a non-removable pin for outswing openings where the barrel is on the secure side. All three are larger than 4" x 4", so the door and frame have to be prepped for the bigger leaf.
10) The Ives 1021RP has a removable pin - what is the equivalent when the door swings out and the hinge pin is exposed?
The Ives 1021RP uses button non-rising pins with caps, which lift out so the door can be taken down for maintenance. On an outswing exterior door that pin sits on the unsecured side. The Hager BB1168 is a full mortise heavy duty ball bearing hinge with a non-removable pin, and the Deltana CSB45N is a 4-1/2" x 4-1/2" square hinge sold in pairs with a non-removable pin. For a steel hinge that keeps the 4" x 4" size and 5/8" radius corner, the Deltana DE44R5TA is a 4" x 4" x 5/8" radius security hinge in steel, sold as a pair.
11) What finishes do the Ives 1021RP hinges come in?
Five finishes across the 1021RP: 646 Satin Nickel, 631 Matte Black, 651 Bright Chrome, 652 Satin Chrome, and 643E Aged Bronze. For matching a building already in service, 652 Satin Chrome is the usual commercial pairing with 626 satin chrome lever trim, and 651 Bright Chrome pairs with polished trim. If your other openings run brass or oil rubbed bronze, 643E Aged Bronze is the closest of the five.
12) Do the Ives 1021RP hinges come with screws, and will they work on a metal frame?
Both wood and machine screws are covered. The set ships with #9 x 1 flat phillips head wood screws for the wood door leaf, and the fastener spec on the 1021 is wood and machine screws, the machine screws being what threads into a tapped hollow metal frame. No separate fastener pack to order.
13) I need 3-1/2 inch hinges, not 4 inch. What is the equivalent?
The 1021RP is only made at 4" x 4", so for a 3-1/2" pocket you need a different part. ZenSupply carries the Schlage Residential S3P1010 3-1/2" x 3-1/2" plain bearing mortise hinge in packs of three, the same bearing type and count, though it has square corners rather than radius. The Delaney RH35xx is a 3-1/2" x 3-1/2" steel residential hinge with the same 5/8" radius corner, sold in pairs, if matching the corner profile matters more than the pack size.
14) Do I have to specify handing when ordering Ives 1021RP hinges?
No handing to specify. The 1021 is a five knuckle full mortise butt hinge with a removable pin, so the same hinge hangs a left or a right hand door; you just flip it. Handing only comes into play on hinges with a built-in direction, such as electrified or concealed conductor models like the Stanley CECB1900R54L, which is ordered left-handed. Order the 1021RP by size and finish only.
15) Which ANSI standards do the Ives 1021 hinges meet?
Two matter here for a spec submittal. The 1021 is certified to exceed ANSI/BHMA A156.1 performance requirements, and it meets ANSI/BHMA 156.7 template hinge dimensions, which is the standard that keeps the hole pattern interchangeable with other template hinges of the same size. Its performance class is Grade 3 at 350,000 cycles. That template compliance is the practical part: it means a standard 4" x 4" machine-prepped frame takes it without new holes.
16) Can I standardize a whole apartment building on the Ives 1021RP?
For interior unit doors, yes, provided every leaf is under 70 lbs and no larger than 3'0" x 7'0". Buying one model in one finish across the units means one screw type, one spare on the shelf, and identical template prep on every opening. The doors that fall outside it are the ones to plan separately: unit entry doors, corridor and stair doors, and anything fire rated or with a closer, which want a ball bearing or heavy weight hinge instead. Order one 3-hinge set per interior leaf.
17) Is a ball bearing hinge the same thing as the Ives 1021RP plain bearing hinge?
No. The Ives 1021RP is a plain bearing hinge, rated Grade 3 for 350,000 cycles and intended for standard weight doors in low frequency use. A ball bearing hinge such as the Orca Hardware 4-1/2" x 4-1/2" Square Corner Ball Bearing Commercial Hinge or the Delaney 4" x 4" Commercial Ball Bearing Hinge with square corners carries bearing races between the knuckles instead. They can share a size but the bearing type is a different mechanism, and the Orca ball bearing model is 4-1/2" x 4-1/2" rather than 4" x 4". Match bearing type when you are standardizing hinges across a building so the doors swing the same way.
18) What 4 inch by 4 inch hinge with 5/8 inch radius corners can be used on exterior residential doors instead of the Ives 1021RP?
The Ives 1021RP carries the same 5/8" radius corner and 4" x 4" size, and is recommended for doors under 70 lbs up to 3'0" x 7'0". The Delaney 4" x 4" Bulk Residential Hinges Exterior are sold as a pair with the same 5/8" radius corner for exterior residential openings, and the Delaney 4" x 4" Residential Hinges for Castlegate come in a 5/8" radius by square combination for doors prepped with one radius leaf and one square leaf. Confirm which corner the door and which corner the frame were cut for before ordering a radius-by-square pair.
19) Can a half mortise or full surface hinge replace the Ives 1021RP?
Not without changing the door and frame prep. The Ives 1021RP is a full mortise hinge, meaning both leaves mortise into the door edge and the frame rabbet. The Hager 1129 is a half mortise plain bearing commercial hinge in 4-1/2" standard weight steel, which mortises into the door but applies to the frame face - that suits a channel iron frame, not a routed wood or hollow metal jamb. The Hager 990 STEEL is a full surface plain bearing hinge at 3" x 4" that applies to both faces with no mortise at all. The mounting style has to match how the existing opening was built.
20) Will a spring hinge or a pivot work in place of the Ives 1021RP if the door needs to self-close?
The Ives 1021RP is a plain bearing full mortise hinge with no closing mechanism - the door stays where you leave it. The Stanley Security 2060R is a full mortise spring hinge at 4.5" x 4.5" with square corners on a ferrous steel base, heavy duty, which carries the closing spring inside the barrel. If the opening swings both directions rather than one, that is pivot territory: the BEST DAP-3 is a heavy duty double acting pivot for commercial interior doors, which is a different mounting system entirely and not a mortise hinge swap.
21) Is the Ives 1021RP suitable for a detention or correctional opening?
No. The Ives 1021RP is a medium duty steel plain bearing hinge for doors under 70 lbs and up to 3'0" x 7'0". Detention openings use a different class of hinge: the BEST BB855 is a heavy-duty steel double weight concealed ball bearing prison hinge, and the Stanley Security double weight prison hinge is a 5" by 6" heavy duty hinge furnished with no holes and not swaged, so it is welded or drilled to suit the frame on site.
22) The doors are 4-1/2 inch standard weight full mortise - what takes the place of the Ives 1021RP at that size?
The Ives 1021RP is 4" x 4" and does not cover a 4-1/2 inch prep. At 4-1/2 inch, the Stanley Security FBB191 is a 5-knuckle full mortise standard weight hinge at 4.5" x 4.5", and the McKinney MP79 MacPro is a 5-knuckle full mortise standard weight hinge in standard duty. The McKinney SQ3331 is a 4-1/2" by 4-1/2" square barrel 2-knuckle decorative hinge if the barrel appearance matters on the opening. Hinge width follows door thickness and trim clearance, so verify the existing leaf width before moving from 4 inch to 4-1/2 inch.
23) The Ives 1021RP is steel - what should be specified for a coastal or corrosive opening?
The Ives 1021RP has a steel substrate, which is what makes it appropriate for the dry interior and light commercial openings it is recommended for. Where the environment attacks a ferrous base, the McKinney T2314 is a non ferrous standard weight 5 knuckle hinge in medium duty, and the Don-Jo HWBB85045 is a heavy weight full mortise ball bearing hinge in brass at 5" x 4-1/2" with a satin chrome finish. Both change the base material rather than just the plating, which is the part that matters when salt air is the problem.
24) What is the actual model number I order, the 1021 or the 1021RP?
1021RP is the part number to order, and it's the MPN. The 1021 is the base model in the Ives 1000 Series; the RP suffix denotes the removable pin configuration, which is the button non-rising pin with caps. Variant part numbers carry the finish code, for example 1021RP F 626E in 652 Satin Chrome and 1021RP F 622E in 631 Matte Black.
25) Ordering hinges for a whole floor of doors - how do the pack quantities compare between the Ives 1021RP and other hinges?
The Ives 1021RP ships as a set of three hinges with #9 x 1 FPHWS fasteners for wood doors, which is the count a standard 7 foot door takes, so one set covers one opening. The Schlage Residential S3P1010 is also a pack of three at 3.5" x 3.5". Most of the alternatives are sold in pairs - the Delaney 3-1/2" x 3-1/2" bulk interior residential hinges, the Delaney 4" x 4" bulk exterior residential hinges, the Emtek 91013, and the Deltana DSB35 3-1/2" x 3-1/2" residential square hinge are all pair quantities, so a three hinge door needs two packs or a bulk count worked out against the door schedule.
