Don-Jo RPB7404014-652 – Frequently Asked Questions

1) What is the difference between a 1/4 inch radius and a 5/8 inch radius hinge, and how do I tell which one I need?
It is the curve on the two outer corners of each leaf, and it has to match the mortise the router or template cut. The Don-Jo RPB7404014 has 1/4 inch radius corners, a tighter curve than the 5/8 inch radius used on a lot of residential prehung doors. Pull one existing hinge and hold it against the new one: if the corner arc is visibly larger, you want a 5/8 inch radius hinge instead, such as the Delaney 4 x 4 bulk residential hinges in 5/8 inch radius. Square-cut pockets, common on site-built and commercial frames, need a square corner hinge.
2) Is the Don-Jo RPB7404014 heavy enough for apartment entry doors, or is it an interior-door hinge?
It is a residential-duty hinge in 0.097 gauge steel, which suits interior passage and bedroom doors and light-duty residential openings. For a solid-core apartment entry, a corridor door, or anything on a closer or seeing daily traffic, step up to a commercial ball bearing hinge: the Orca Hardware 4 x 4 x 1/4 inch radius corner is a medium duty plain bearing commercial hinge in the same size and corner style, and the Delaney 4 x 4 commercial ball bearing hinge is a bearing option if the door is heavy.
3) The door mortises are cut square, not radius - what 4 inch hinge fits that prep?
A square corner prep needs a square corner hinge. The Orca Hardware 4040 Series is a 4 inch by 4 inch square corner plain bearing hinge, medium duty, and the Delaney CH401X is a 4 inch by 4 inch commercial ball bearing hinge with square corners. The Don-Jo RPB7404014 is cut with 1/4 inch radius corners, which will leave a gap at the corners of a square pocket unless the pocket is squared off or the hinge corners are chiseled in.
4) Is the Don-Jo RPB7404014 the right hinge for a commercial opening with heavy traffic?
The RPB7404014 is classified residential and built from 0.097 gauge steel. For openings carrying commercial traffic, 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 steel hinge rated heavy duty, and the Hager BB1168 is a full mortise ball bearing heavy duty hinge with a non-removable pin. Bearing hinges carry the friction of frequent cycling in the bearing rather than the knuckle.
5) Which hinge should I use on an exterior residential door instead of the Don-Jo RPB7404014?
For an out-swinging or exterior residential opening, look at the Delaney RH45xx, a 4 inch by 4 inch bulk residential exterior hinge with 5/8 inch radius corners, or the Deltana DE44R5TA, a 4 inch by 4 inch hinge with 5/8 inch radius corners built as a security hinge in steel with a tamper-resistant configuration. Both are 4 inch by 4 inch like the Don-Jo RPB7404014, but their 5/8 inch radius corners will not seat in a mortise cut for the RPB7404014's 1/4 inch radius without recutting.
6) Does the Don-Jo RPB7404014 hinge come handed, or does one part number work on left and right doors?
One part number covers both swings. A full mortise butt hinge like the RPB7404014 is symmetrical, so the same hinge works on a left hand or right hand door. You only choose which leaf goes on the door and which on the jamb at install. Handing only becomes an ordering decision on hinges with an electrified conductor or a specific tip, not on a plain 4 x 4 residential butt.
7) How many Don-Jo RPB7404014 hinges do I get, and how many doors will that cover?
They ship in a shelf pack of 50. Standard practice is three hinges per door on a 4 x 4 opening, so a pack covers 16 doors with two left over, or 25 doors at two hinges each on lighter interior slabs. That quantity is aimed at builders and distributors stocking residential work rather than a single-door repair.
8) What finishes does the Don-Jo RPB7404014 residential hinge come in?
Seven, and they cover the usual residential trim families: 632 bright brass, 633 satin brass, 640 satin bronze dark, 646 satin nickel, 647 antique nickel, 651 bright chrome, and 652 satin chrome. All are plated over the steel base. If you are matching a fleet of doors, 652 satin chrome and 646 satin nickel are the two that read closest to the brushed lever finishes most builders spec.
9) Should I use a plain bearing hinge like the Don-Jo RPB7404014 or spend up for ball bearing?
Weight and traffic decide it. A residential butt hinge like the RPB7404014 handles hollow-core and light solid-core doors on normal household use. Once you hang a heavy solid-core slab, add a door closer, or put the door in a corridor that cycles all day, a bearing hinge carries the load without wearing the knuckles: the Delaney 4 x 4 commercial ball bearing hinge and the Orca 4-1/2 x 4-1/2 square corner ball bearing commercial hinge are both bearing options. Bearing hinges are also what most commercial specs call for outright.
10) Do the electrified hinges look like a substitute for a standard 4 inch residential hinge?
They mount in the same full mortise pocket but they are not interchangeable. The BEST CECB179-12C is a steel full mortise concealed bearing electrified hinge with a 12-wire quick connect, and the Command Access ETH-CB70 is a 3-knuckle standard weight energy transfer hinge on a steel base, both rated medium duty. Those carry power through the hinge to an electrified lock or exit device and require a raceway and prepped frame. The Don-Jo RPB7404014 is a plain steel residential hinge with no wire path - if the opening has no electrified hardware, the transfer hinge adds prep you do not need.
11) I need the door to self-close - is there a hinge alternative to adding a closer?
The Stanley Security 2060R is a full mortise spring hinge, square corner, 4.5 inch by 4.5 inch on a ferrous steel base, rated heavy duty - the spring in the barrel returns the door without a surface closer. The Don-Jo RPB7404014 is a standard 4 inch by 4 inch full mortise hinge with no closing mechanism, so a door hung on it stays where it is left. Note the size difference: the Stanley is 4.5 by 4.5 with square corners against the Don-Jo's 4 by 4 with 1/4 inch radius corners, so the mortise prep is not shared.
12) What is the difference between a plain bearing hinge and a ball bearing hinge when picking a 4 inch replacement?
In a plain bearing hinge the knuckles bear directly on each other; a ball or concealed bearing hinge puts bearings between the knuckles to carry the load as the door swings. Among 4 inch options, the Orca 4014 Series and Orca 4040 Series are plain bearing, and the Delaney CH401X is a ball bearing hinge with square corners. Bearing hinges are typically specified for heavier door leaves and higher cycle counts; plain bearing suits lighter residential leaves like the ones the Don-Jo RPB7404014 in 0.097 gauge steel is built for.
13) Is a half mortise or full surface hinge an option in place of a full mortise hinge?
Only if the frame cannot take a mortise. The Hager 1129 is a half mortise plain bearing commercial hinge, 4-1/2 inch standard weight steel - one leaf mortises into the door, the other surface-applies to the frame. The Hager 990 STEEL is a full surface hinge, 3 inch by 4 inch, with a welded tip. Both are for openings where channel iron frames or existing conditions rule out cutting a pocket. The Don-Jo RPB7404014 is a full mortise hinge, so both leaves seat flush into routed pockets in the door and jamb.
14) What 4-1/2 inch hinge should I order if the doors are heavier than standard residential leaves?
Move up in leaf size. The Stanley Security FBB191 is a 5-knuckle full mortise standard weight hinge in 4.5 inch by 4.5 inch rated heavy duty, and the Orca 3535 Series is a 4-1/2 inch by 4-1/2 inch square corner ball bearing commercial hinge rated medium duty. The wider leaf spreads the load across more of the door edge than the 4 inch by 4 inch the Don-Jo RPB7404014 provides, but the mortise has to be widened and deepened to suit.
15) Which alternatives ship in bulk quantities for a multi-unit residential job?
The Don-Jo RPB7404014 is packed 50 to a shelf pack. Among the alternatives, the Delaney RH35xx and RH45xx are bulk residential hinges sold by the pair, and the Schlage Residential S3P1010 comes as a pack of 3 - a set per door for a three-hinge opening. For a unit turn where every door takes the same hinge, the difference is whether you are counting pairs or counting doors.
