Don-Jo RPB7353558-652 – Frequently Asked Questions

1) Will a Don-Jo RPB7353558 hinge drop into an existing 3-1/2 inch residential door mortise?
If the existing mortise is a standard 3-1/2 x 3-1/2 inch residential prep with 5/8 inch radius corners, yes. The RPB7353558 is a full mortise hinge at that exact size with a pre-formed 5/8 inch radius corner, which is the common factory prep on prehung residential doors. If the door and jamb are routed with square corners instead, the radius leaf will leave a visible gap at the corners, and Don-Jo offers the same hinge in a square corner style by special order.
2) Is the Don-Jo RPB7353558 heavy enough for apartment entry doors or commercial use?
It's built as a residential hinge, 0.085 gauge steel, and Don-Jo rates its use for residential doors and light commercial interior doors. For a solid-core unit entry door in a multifamily building, or any opening on a closer, go to a commercial ball bearing or concealed bearing hinge instead: the Ives 3CB1 is a medium duty concealed bearing full mortise hinge, and the Ives 3CB1HW is the heavy weight version. A plain residential hinge on a closer-equipped door wears at the knuckle and starts to sag.
3) My existing hinges are 4 inch, not 3-1/2 inch. Will the Don-Jo RPB7353558 work?
No. Leaf size has to match the mortise. A 3-1/2 x 3-1/2 inch hinge in a 4 inch recess leaves a half inch of open rout top and bottom and puts the screws in the wrong holes. Measure the height of the existing leaf with the door closed and match it. At 4 x 4 with a 5/8 inch radius, Delaney's 4 x 4 residential exterior hinge is the matching size and corner; the Orca Hardware 4 x 4 square corner plain bearing commercial hinge covers a square 4 inch prep.
4) Will the Don-Jo RPB7353558 work for an access control door that needs power to the lock?
No. The Don-Jo RPB7353558 is a plain residential full mortise hinge with no wire path through it. To carry power through the door, you need an electrified or energy transfer hinge: the BEST CECB179-12C is a steel full mortise concealed bearing electrified hinge with a 12-wire quick connect rated medium duty, the Command Access ETH-CB70 is a 3-knuckle standard weight energy transfer hinge on a steel base rated medium duty, and the Command Access ETH-BB68 is the 5-knuckle heavy duty version. If you also need to monitor door position, the Command Access ETM-CB70 adds door position sensing on a 3-knuckle steel base and the ETM-BB68 adds an integrated door position switch on the heavy duty body.
5) What is the closest equivalent to the Don-Jo RPB7353558 3-1/2 inch residential hinge from another brand?
The Delaney RH35xx is the nearest match: a 3-1/2 inch by 3-1/2 inch bulk steel residential interior hinge with 5/8 inch radius corners, the same size and same corner profile as the Don-Jo RPB7353558. Both drop into a standard residential door prep cut for a 3-1/2 inch hinge with a 5/8 inch radius, so a swap needs no rework of the mortise. The main ordering difference is how they come: the Delaney RH35xx is sold as a pair, while the Don-Jo RPB7353558 comes in a shelf pack of 50.
6) My door prep has square corners, not radius. What 3-1/2 inch hinge should I use instead of the Don-Jo RPB7353558?
The Don-Jo RPB7353558 is cut with a 5/8 inch radius corner, so it will not sit flush in a square-corner mortise. For a square-corner prep at the same 3-1/2 inch by 3-1/2 inch size, the Emtek 91013 residential plain bearing hinge, the Deltana DSB35 residential square hinge, and the Schlage Residential S3P1010 square corner plain bearing hinge all come with square corners in that size. The Emtek 91013 and the Deltana DSB35 are sold as pairs and the Schlage S3P1010 comes in a pack of three, which matches a standard three-hinge interior door. Don-Jo also builds the RPB7353558 in a square corner style as a special order if you want to stay with one brand across the building.
7) Is the Don-Jo RPB7353558 heavy enough for a high-traffic commercial corridor door?
The Don-Jo RPB7353558 is built as a residential hinge in 0.085 gauge steel, sized for standard residential door preparations and light commercial interior doors. For a door cycling all day in a corridor, the commercial bearing hinges in the same general size class are the better fit: the Ives 3CB1 is a 3-knuckle concealed bearing full mortise hinge rated medium duty, the Ives 3CB1HW is a heavy weight concealed bearing full mortise hinge with 3 knuckles, and the Orca Hardware 3514 Series is a 3.5 inch by 3.5 inch plain bearing commercial hinge rated medium duty. Note the Orca 3514 uses a 1/4 inch radius corner rather than 5/8 inch, so confirm the corner profile of the existing prep before ordering.
8) I need 4 inch hinges with 5/8 inch radius corners instead of 3-1/2 inch. What are my options?
The Don-Jo RPB7353558 is made only at 3-1/2 inch by 3-1/2 inch, so a 4 inch prep needs a different part. In the 4 inch by 4 inch size with the same 5/8 inch radius corner, the Delaney RH45xx is a bulk residential exterior hinge sold in pairs, and the Delaney RH40xx is a residential hinge for Castlegate doors offered 5/8 inch radius by square, also in pairs. If the 4 inch opening is a security application, the Deltana DE44R5TA is a 4 inch by 4 inch 5/8 inch radius steel security hinge with TT, sold as a pair.
9) Can I use the Don-Jo RPB7353558 on an exterior entry door?
The Don-Jo RPB7353558 is specified as a residential hinge for standard residential door applications and light commercial interior doors. For an exterior leaf, the Delaney RH45xx is built specifically as a bulk residential exterior hinge in 4 inch by 4 inch with a 5/8 inch radius corner, sold in pairs, which is the more common size for an entry slab anyway. If the exterior door is an out-swinging one where the pin is reachable from outside, look at a non-removable pin hinge such as the Deltana CSB45N 4-1/2 inch by 4-1/2 inch square hinge with NRP, or the Hager BB1168 non-removable pin full mortise ball bearing heavy duty hinge.
10) Do I need to order left hand or right hand Don-Jo RPB7353558 hinges?
No handing to specify. A full mortise butt hinge at 3-1/2 x 3-1/2 inches is symmetrical and non-handed, so the same hinge works on a left or right swing door. The only choice you make is the finish.
11) What finishes does the Don-Jo RPB7353558 residential hinge come in, and which matches brushed nickel lever sets?
Seven finishes: 632 bright brass, 633 satin brass, 640 dark satin bronze, 646 satin nickel, 647 antique nickel, 651 bright chrome, and 652 satin chrome. For brushed or satin nickel levers, 646 is the match. Polished brass trim takes 632, and 652 satin chrome pairs with brushed chrome or satin stainless-look hardware.
12) How many hinges do I need per door, and how is the Don-Jo RPB7353558 packed?
Standard residential interior doors take three hinges per leaf, hollow-core slabs sometimes two. The RPB7353558 ships in a shelf pack of 50 pieces, so one pack covers roughly 16 three-hinge doors. That bulk pack is aimed at builders, property maintenance shops and distributors doing whole buildings, not at a single door repair. If you only need a pair, a pair-packed residential hinge like the Delaney 3-1/2 x 3-1/2 bulk steel interior hinge in 5/8 inch radius is the same size and corner profile.
13) Can I standardize every interior door in a rental building on one hinge?
That's what a 50 piece shelf pack of the RPB7353558 is for. Pick one finish, and every 3-1/2 inch radius-corner interior opening in the building takes the same part, so turns and repairs pull from one bin instead of chasing matches. Two things break the standard: exterior or unit entry doors, which are usually 4 x 4 inches and want a heavier hinge, and any square corner prep. For 4 inch exterior openings, Delaney's 4 x 4 exterior residential hinge in 5/8 inch radius keeps the same corner profile a size up.
14) Should I use a plain residential hinge or a ball bearing hinge on interior doors?
For hollow-core and light solid-core interior doors with no closer, a plain residential butt like the 0.085 gauge steel RPB7353558 is what the opening was built for, and it's the cheaper way to do volume work. Ball bearing makes sense where the door is heavy, gets constant traffic, or is pulled by a closer, because the bearings carry the load instead of the knuckle. Stepping up in the same 3-1/2 inch size, the Emtek 94013 is a heavy duty ball bearing pair and the Emtek 92013 a heavy duty plain bearing pair, both square corner.
15) Is the Don-Jo RPB7353558 a security hinge with a non-removable pin?
No. It's a standard residential full mortise butt, so the pin comes out and the leaves separate, which is how you pull a door without unscrewing anything. On an outswing exterior door where the barrel is exposed outside, that's a vulnerability and you want a non-removable pin or a security stud hinge instead: the Deltana CSB45N is a 4-1/2 inch square hinge with NRP, and the Deltana DE44R5TA is a 4 x 4 security hinge with 5/8 inch radius corners.
16) What is the closest match to a builder-grade 3-1/2 inch radius corner hinge from another brand?
Staying at 3-1/2 x 3-1/2 inches with a 5/8 inch radius corner, the direct equivalent is Delaney's bulk steel residential interior hinge, which carries the same size and the same 5/8 inch radius and ships as a pair. If the prep is square rather than radius, the same-size options are the Schlage Residential S3P1010 plain bearing mortise hinge in packs of three, the Ives 1010RP steel plain bearing residential hinge in sets of three, and the Emtek 91013 residential plain bearing pair. Size and corner style are what have to match; brand does not.
17) What is the difference between the Don-Jo RPB7353558 and the Emtek 92013 or 94013 heavy duty hinges?
All three are 3-1/2 inch by 3-1/2 inch steel hinges. The Don-Jo RPB7353558 is a residential full mortise hinge in 0.085 gauge steel with 5/8 inch radius corners. The Emtek 92013 is a heavy duty plain bearing hinge and the Emtek 94013 is a heavy duty ball bearing hinge, both in plated steel with square corners and both sold as pairs. The bearing distinction is the one that matters on a door with a closer or a heavy slab: the 94013 carries ball bearings, while the 92013 and the Emtek 91013 residential hinge run plain bearing. Corner profile decides the swap regardless of bearing type, since the Emtek hinges are square and the Don-Jo is radius.
18) I need the door to self-close. Is there a hinge alternative to the Don-Jo RPB7353558 that does that?
The Don-Jo RPB7353558 is a standard full mortise hinge with no closing mechanism, so the door swings free. For a hinge that closes the door itself, the Stanley Security 2060R is a spring hinge, full mortise, square corner, 4-1/2 inch by 4-1/2 inch on a ferrous steel base and rated heavy duty. It is a larger size and a square corner, so the existing 3-1/2 inch radius prep on a door using the RPB7353558 would need to be recut on both the door and the frame.
19) Is the Ives 1010RP the same thing as the Don-Jo RPB7353558?
They are close in role but not interchangeable in a prep. Both are steel residential full mortise hinges. The Ives 1010RP is a plain bearing residential hinge in the Ives 1000 series rated medium duty, and it has square corners, sold as a set of three. The Don-Jo RPB7353558 has 5/8 inch radius corners and comes in a shelf pack of 50. If the existing mortise is radiused, the square-corner 1010RP will leave a gap at each corner unless the pocket is squared off first.
20) For a multi-family property, should I standardize on the Don-Jo RPB7353558 or a commercial hinge?
For interior unit doors, the Don-Jo RPB7353558 covers the case directly: it is a residential full mortise hinge in 0.085 gauge steel at 3-1/2 inch by 3-1/2 inch, comes in seven finishes including 646 satin nickel and 652 satin chrome, and ships in a shelf pack of 50, which is the quantity a portfolio actually consumes. Where the same property has corridor or stair doors carrying closers, those typically take a commercial bearing hinge instead, such as the Ives 3CB1 3-knuckle concealed bearing full mortise medium duty hinge or the Orca Hardware 4040 Series 4 inch by 4 inch square corner plain bearing commercial hinge. Standardizing on the Don-Jo for unit doors and one commercial bearing line for the traffic doors keeps the stock list to two items.
21) What should I use instead of the Don-Jo RPB7353558 on a detention or high-security door?
A residential hinge is the wrong class of part for a detention opening. 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 at 5 inch by 6 inch furnished with no holes and not swaged, rated heavy duty. For a surface-applied detention condition, the Hager 990 STEEL is a full surface prison hinge at 3 inch by 4 inch with a welded tip, heavy duty and plain bearing.
22) The frame is metal and cannot be mortised. What hinge do I use in place of the Don-Jo RPB7353558?
The Don-Jo RPB7353558 is a full mortise hinge, meaning both leaves recess into the door and the frame. If the frame cannot take a mortise, a half mortise hinge mortises into the door and surface-applies to the frame: the Hager 1129 is a half mortise plain bearing commercial hinge at 4-1/2 inch standard weight steel, rated heavy duty. For a fully surface-applied condition where neither side is cut, the Hager 990 STEEL is a full surface hinge at 3 inch by 4 inch. Both are larger and commercial in build compared with the 3-1/2 inch residential Don-Jo.
23) Does the Don-Jo RPB7353558 hinge come with screws?
Plan on screws separately. What's specified on the RPB7353558 is the hinge itself: 3-1/2 x 3-1/2 inch full mortise, 0.085 gauge steel, 5/8 inch radius corners, in one of seven finishes. If you're replacing sagging hinges on a jamb, longer screws into the stud do more for the door than the hinge does, so pick up 2-1/2 or 3 inch wood screws in the matching finish.
24) Will the Don-Jo RPB7353558 hold a solid core interior door?
On a solid core interior slab hung with three hinges and no closer, a 0.085 gauge steel residential butt is the normal spec and handles it. Where it stops being the right part is a heavy or oversized slab, a door on a closer, or a high-traffic opening like a corridor or stairwell door. Those want a bearing hinge; the Ives 3CB1HW is the heavy weight concealed bearing full mortise choice.
25) Is the Deltana DSB3 a substitute for the Don-Jo RPB7353558?
No, the sizes are different. The Deltana DSB3 is a 3 inch by 3 inch square hinge sold as a pair, while the Don-Jo RPB7353558 is 3-1/2 inch by 3-1/2 inch with 5/8 inch radius corners. A 3 inch hinge will not fill a 3-1/2 inch mortise and the square corners will not match a radiused pocket. Within Deltana, the DSB35 is the 3-1/2 inch by 3-1/2 inch residential square hinge, which at least matches the size.
26) What is a good architectural or decorative alternative to a plain residential hinge like the Don-Jo RPB7353558?
The Don-Jo RPB7353558 is a plain steel residential hinge finished in options such as 632 bright brass, 633 satin brass, 640 satin bronze dark, and 647 antique nickel. If the barrel itself needs to be a design element, the McKinney SQ3331 is a square barrel 2-knuckle decorative hinge at 4-1/2 inch by 4-1/2 inch, standard duty. For a concealed look on the barrel instead, the Hager 920 is a full mortise concealed plain bearing hinge with 2-knuckle steel construction, rated medium duty. Both are 2-knuckle designs and differ in size and prep from the 3-1/2 inch Don-Jo.
27) If I need a 5-knuckle full mortise hinge rather than the Don-Jo RPB7353558, what carries that?
The McKinney MP79 MacPro is a full mortise hinge with 5 knuckles at standard weight, and the McKinney MPB79 MacPro is the 5-knuckle standard weight hinge in the same MacPro family. The Stanley Security FBB191 is a 5-knuckle full mortise standard weight hinge at 4.5 inch by 4.5 inch, rated heavy duty. Where the door is aluminum, brass, or another non-ferrous condition, the McKinney T2314 is a non-ferrous 5-knuckle hinge at standard weight, rated medium duty. All are commercial builds rather than the residential 3-1/2 inch Don-Jo, so check the prep size before switching.
