Don-Jo CP74545-600 – Frequently Asked Questions

1) Is the Don-Jo CP74545 combo pack enough hinges to hang one door, or do I need to order more?
One box of the CP74545 hangs one standard single door. It contains three hinges: two spring hinges and one ball bearing hinge, with screws included. The usual arrangement is the ball bearing hinge in the center position for smooth swing and the two spring hinges at top and bottom doing the closing. For a taller or heavier opening that calls for four hinges, you would need a second box or a fourth hinge ordered separately.
2) Will 4-1/2 x 4-1/2 spring hinges fit the doors I already have in my building?
4-1/2 by 4-1/2 inches is the standard commercial mortise hinge size, so the CP74545 drops into the existing hinge prep on most 1-3/4 inch commercial doors and hollow metal frames without re-mortising. Measure one of the hinges you are pulling: if it reads 4-1/2 by 4-1/2 with the same corner type, the swap is direct. Doors prepped for 3-1/2 or 4 inch hinges are a different mortise and this set will not fill it.
3) Do spring hinges like the Don-Jo CP74545 replace a door closer?
On a light interior commercial door, yes, that is exactly what spring hinges are for: the two spring hinges in the CP74545 pull the door shut on their own, with no overhead closer, no arm, and nothing projecting into the opening. What they do not give you is controlled closing speed, latching force adjustment, backcheck, or hold-open. For an exterior door, a heavy door, or an opening where people need a slow, controlled close for accessibility, you want an overhead closer instead. Spring hinges are the right call for apartment unit doors, stairwell and corridor doors, storage and utility rooms, and anywhere a closer is overkill or would get abused.
4) I need 4-1/2 inch spring hinges but not the combo pack. What else is there?
If you want spring hinges only, the McKinney 1502 is a square corner full mortise standard weight spring hinge in the same 4-1/2 by 4-1/2 size, medium duty. The Hager 1250 is a full mortise standard weight steel spring hinge, with the 1251 being the same hinge in a 1/4 inch round corner and the 1252 in a 5/8 inch round corner, so you can match whatever corner radius your existing mortise has. The Hager 1150 is the stainless steel version of that full mortise spring hinge. All of those are sold as hinges rather than as a three-hinge set, so you order the quantity your opening needs.
5) My door is prepped for 4 inch or 3-1/2 inch hinges, not 4-1/2. What spring hinge do I use instead?
A 4-1/2 inch set like the Don-Jo CP74545 will not fill a smaller mortise, so go to a hinge that matches the prep. In 4 by 4, Orca Hardware makes the SPR4040 in square corner, the SPR4014 with a 1/4 inch radius corner, and the SPR4058 with a 5/8 inch radius corner, all medium duty. In 3-1/2 by 3-1/2, Deltana offers the DSH35R4 single action steel spring hinge with a 1/4 inch radius, and Emtek sells the 95013 as a square corner plated steel pair. Match the corner radius as well as the size, or the mortise will not line up.
6) Can I use the Don-Jo CP74545 on toilet partition doors?
Partition doors are a different product family. Pemko Markar builds spring loaded continuous hinges specifically for toilet partitions with an 80 lb load capacity: the FM400 and FM900 series, the FS402 series, and the FS902 series, which is 304 stainless steel. Those run the full height of the partition door. The Don-Jo CP74545 is a set of individual 4.5 inch by 4.5 inch steel hinges, two spring and one ball bearing, sized for a commercial door frame and slab, so for a partition stall specify one of the Pemko Markar continuous hinges instead.
7) The architect wants the closer hidden. What replaces the Don-Jo CP74545 when no hardware can show on the door edge?
SOSS invisible spring closer hinges mortise fully into the door and frame so nothing is visible when the door is shut. The 216IC series carries a 20 minute fire rating, the 218IC is a 7 inch heavy duty hinge requiring a 1-3/4 inch minimum door thickness, and the 220IC is a 7 inch version with a 20 minute fire rating and a 2 inch minimum door thickness; all three are heavy duty. Confirm your slab meets the thickness minimum before specifying. The Don-Jo CP74545 is a conventional full-size set at 4.5 inch by 4.5 inch whose leaves are visible on the door edge.
8) My frames are prepped for radius corner hinges, not square. What spring hinge should I use instead of the Don-Jo CP74545?
Match the corner radius your frame is prepped for. Hager offers full mortise standard weight steel spring hinges in both radii: the 1251 has 1/4 inch round corners and the 1252 has 5/8 inch round corners, both medium duty. Orca Hardware covers 4 inch by 4 inch openings with the SPR4014 at 1/4 inch radius and the SPR4058 at 5/8 inch radius, also medium duty. The Don-Jo CP74545 is a 4.5 inch by 4.5 inch steel set, so a frame cut for radius corners wants one of the radius hinges above rather than the CP74545.
9) Is there a stainless steel alternative to the Don-Jo CP74545 for a wet or coastal opening?
The Hager 1150 is a full mortise spring hinge in standard weight stainless steel, medium duty, where the Don-Jo CP74545 is a steel set. Hager also lists the 1250 as the full mortise standard weight steel construction version, so the 1150 and 1250 are the stainless and steel members of the same pattern. If the substrate is what is driving the decision, the 1150 is the stainless option.
10) The fire door inspection calls for a UL listed spring hinge. Does the Don-Jo CP74545 cover that, or should I specify something else?
If the inspector wants the listing called out on the hinge itself, specify a hinge whose description carries it: the Design Hardware UL Spring Hinge is a medium duty UL spring hinge, and the Emtek 95013 is a UL listed spring hinge pair at 3-1/2 inch by 3-1/2 inch with square corners in plated steel. The SOSS 216IC and 220IC are invisible spring closer hinges with a 20 minute fire rating, both heavy duty. The Don-Jo CP74545 is a commercial 4.5 inch by 4.5 inch steel three-hinge set whose two spring hinges give the self-closing action; where a specific listing or rating has to appear on the submittal, order against one of the hinges above.
11) Why does the Don-Jo CP74545 mix a ball bearing hinge in with the spring hinges instead of using three springs?
The ball bearing hinge carries the swing. Spring hinges are plain-barrel, tension-loaded units, and running three of them on one door makes the swing stiff and noisy and wears the knuckles faster. Putting one ball bearing hinge in the set gives the door a smooth, quiet pivot while the two spring hinges supply the closing force. It also means you only have two hinges to tension when you set it up, instead of three fighting each other.
12) What finish should I order the Don-Jo CP74545 in to match my existing door hardware?
Six finishes are offered on the CP74545: 600 primed for painting, 632 bright brass, 633 satin brass, 639 satin bronze, 640 satin bronze dark, and 651 bright chrome. Match the BHMA number on your existing hardware and the hinges will line up with it. For hollow metal frames that get field-painted, 600 is the one to order, since it is primed and takes paint. For a satin chrome or brushed stainless look (652 or 630 territory) this steel set is not the match.
13) Is the Don-Jo CP74545 heavy enough for a high-traffic commercial door?
The CP74545 is steel at 0.134 gauge and rated by Don-Jo as a commercial product, which puts it in the range used on office, school, healthcare, retail, and multi-tenant residential openings. That gauge is standard weight, not heavy weight. For an unusually heavy door, a wide door with a long lever arm, or an entrance taking constant abuse, spec a heavy weight hinge and a separate closer rather than relying on spring hinges alone.
14) Will spring hinges work on a fire door, and does the Don-Jo CP74545 carry a UL listing?
Self-closing is only half of what a fire door assembly needs; the hinges themselves have to be listed for that use, and the listing has to be confirmed on the specific part you install. If UL listing is what your inspector needs on paper, the Design Hardware UL Spring Hinge is a medium duty spring hinge sold as UL, and the Emtek 95013 pair is listed as UL Listed plated steel. On fire openings, spec from the listed product and match the label on the door.
15) Is a double action saloon hinge a substitute for the Don-Jo CP74545 spring hinge set?
No. The Deltana DASHS is a double action saloon hinge sold each in 4 inch, 5 inch and 6 inch heights, and the Deltana DASH95 is a double action spring hinge with solid brass cover plates; double action means the leaf swings both directions and returns to center, which is a cafe or pass-through door. The Don-Jo CP74545 is a single-direction commercial door set, two spring hinges and one ball bearing hinge at 4.5 inch by 4.5 inch in steel, for a door that closes into a frame and latches. They are not interchangeable.
16) I need to be able to pull the door without unscrewing the hinges. What spring hinge alternative has a removable pin?
BEST lists two removable pin spring hinges: the 2060R, a plain bearing spring hinge with removable pin in square corners standard weight, and the RD2060R, the plain bearing radius corner standard weight version, both medium duty. Removable pin lets the slab come off the frame without backing out the leaf screws. The Don-Jo CP74545 set pairs its two spring hinges with a ball bearing hinge for smooth, quiet swing under continuous use, so the choice is between bearing type and the removable pin feature.
17) I only need the self-closing hinges, not a full three-hinge set. What is the simpler option next to the Don-Jo CP74545?
Buy the spring hinges on their own. The Hager 1250 is a full mortise standard weight steel spring hinge, and the Orca Hardware SPR4040 is a 4 inch by 4 inch square corner spring hinge, both medium duty and both sold as hinges rather than a packaged opening. The Don-Jo CP74545 bundles two spring hinges plus one ball bearing hinge and screws in one box at 4.5 inch by 4.5 inch, which is the right call when you are hanging a door from scratch and the wrong one when you are only swapping the closing hinges on a door that already has good bearing hinges.
18) My frame has a Z hole pattern. Which spring hinge matches that instead of the Don-Jo CP74545?
The Orca Hardware SPR4058Z is a 4 inch by 4 inch spring hinge with a 5/8 inch radius corner and a Z hole pattern, medium duty; the SPR4058 is the same 4 inch by 4 inch 5/8 inch radius corner hinge without the Z pattern. Hole pattern has to match the existing frame drilling or you are filling and re-drilling. The Don-Jo CP74545 comes as a 4.5 inch by 4.5 inch steel three-hinge set with screws included.
19) Do the Don-Jo CP74545 hinges come with screws, or do I need to buy fasteners separately?
Screws ship in the box. The CP74545 is put together as a ready-to-install package, so a service tech can pull one box off the truck and hang the door without a second trip to the counter for fasteners. Note that spring hinges also need a tension pin or hex wrench to set the closing force after mounting, which is the one step that catches people who have only hung plain butt hinges before.
20) I manage a large property and need to standardize self-closing hinges across a lot of unit doors. Does the Don-Jo CP74545 come in bulk?
The CP74545 is packed 24 per shelf pack, with each box being one complete three-hinge door set. That means one shelf pack covers 24 doors, which makes it workable for a turn crew or a stocking distributor doing repeat unit-door work. Standardizing on one finish across the property, and 600 primed is the usual pick when the frames get painted, keeps the replacement part identical every time.
