Installation & Operation

  1. Review manufacturer specifications and verify door preparation requirements including door thickness, weight capacity (45-70 lbs), and mortise dimensions for proper hinge installation.
  2. Use manufacturer-provided templates to mark mortise locations accurately on both door and frame, ensuring proper alignment for 3.5" x 3.5" or 4" x 4" hinge size.
  3. Prepare door and frame by routing mortise pockets to accommodate full mortise installation with 5/8" radius corners.
  4. Install hinges using appropriate wood fasteners (3-1/2" doors use 3/4 X 9 screws, 4" doors use 1 X 9 screws) and secure per manufacturer torque specifications.
  5. Adjust spring tension as needed - full spring tension may not be required on all hinges depending on door weight and environmental conditions.
  6. Test door operation to verify proper self-closing function and smooth operation throughout full range of motion. Consider wind conditions, drafts, and carpeting drag when making final adjustments. Refer to manufacturer documentation for complete installation details.

Hager 1752426D – Frequently Asked Questions

1) How heavy a door will the Hager 1752 spring hinge close?
The 1752 is rated for doors of 45 to 70 lbs, which puts it in medium-duty territory. That covers most hollow core and light solid core interior doors on apartments, offices and stairwells. A heavier solid core or a mineral core fire door past 70 lbs needs a closer or a heavier hinge instead. Note also that a spring hinge is not a fire door closer substitute unless the assembly calls for it.
2) How many spring hinges do I need per door, and can I mix them with regular hinges?
Hager's guidance on the 1752 is to use all spring hinges, or a combination of spring hinges and ball bearing hinges. Do not pair them with plain bearing hinges. Full spring tension is not required on every hinge either, so on a light door you can tension one and leave a second closer to neutral. Tension is what you adjust when the door drags on carpet, fights a draft, or sits in a twisted frame.
3) Is the Hager 1752 spring hinge ANSI Grade 1?
Yes, BHMA certified Grade 1 to ANSI 4156.17, carrying ANSI K81071F. For a facilities or MRO spec that calls out a Grade 1 self-closing hinge on commercial openings, the 1752 meets it. The catalogued ANSI/BHMA designation on the product record is K81071F.
4) The frames on my building are prepped for square corner hinges, not radius. What spring hinge should I use instead of the Hager 1752?
The Hager 1752 is built with a 5/8 inch radius corner and will not sit correctly in a square corner mortise. For square corner prep, the Orca Hardware SPR4040 is a 4 inch by 4 inch square corner spring hinge in medium duty, and the BEST 2060R is a square corner standard weight spring hinge with a removable pin, also medium duty. In a 3-1/2 inch by 3-1/2 inch size, the Emtek 95013 is a square corner spring hinge pair in plated steel and is UL listed. Confirm the corner style of the existing prep before ordering, since radius and square leaves are not interchangeable in a routed pocket.
5) My existing hinge prep has a 1/4 inch radius corner. Will the Hager 1752 fit, or do I need a different spring hinge?
The Hager 1752 uses a 5/8 inch radius corner, which is a larger radius than a 1/4 inch corner prep and will leave a gap at the corners of the mortise. For 1/4 inch radius prep, the Orca Hardware SPR4014 is a 4 inch by 4 inch 1/4 inch radius corner spring hinge in medium duty. In the 3-1/2 inch by 3-1/2 inch size, the Deltana DSH35R4 is a single action steel spring hinge with a 1/4 inch radius. Radius size is the detail to verify off the door, since the leaf corner has to match the routed pocket.
6) Can I use Pemko Markar FM400 or FS402 spring hinges in place of the Hager 1752 on a commercial entry door?
No. The Pemko Markar FM400 and the Pemko FS402 are spring loaded continuous hinges built for toilet partitions with an 80 lb load capacity, and the Pemko Markar FS902 is the same type in 304 stainless steel. A continuous hinge runs the full height of the door leaf and needs a different prep entirely. The Hager 1752 is a full mortise leaf hinge in 3-1/2 inch by 3-1/2 inch and 4 inch by 4 inch sizes that mounts in individual routed pockets, so the two are not swaps for one another regardless of the door.
7) Which spring hinge should I use if the door has to swing both directions?
The Hager 1752 is a full mortise single-swing spring hinge and closes a door in one direction. For a door that swings both ways, the Deltana DASH95 is a double action spring hinge with solid brass cover plates, and the Deltana DASHS is a double action saloon hinge sold each in 4 inch, 5 inch and 6 inch heights. Those are the parts for a cafe or pass-through opening; the 1752 is the part for a conventional self-closing door in a rabbeted frame.
8) My openings are prepped for 4-1/2 inch hinges. Is there a spring hinge that size instead of the Hager 1752?
The Hager 1752 comes in 3-1/2 inch by 3-1/2 inch and 4 inch by 4 inch sizes only. For a 4-1/2 inch by 4-1/2 inch prep, the McKinney 1502 is a square corner full mortise standard weight spring hinge in 4-1/2 inch by 4-1/2 inch, rated medium duty. Note it is a square corner leaf, so it suits frames routed square rather than radiused.
9) What screws does a 1752 spring hinge take on a wood door?
Wood fasteners, sized to the leaf: 3-1/2 inch hinges take 3/4 x 9 screws, and 4 inch hinges take 1 x 9 screws. Worth confirming your fastener count before the crew is on site, since a spring hinge pulls harder on the screws than a plain butt does.
10) Should I use a spring hinge or a door closer for a self-closing door?
A spring hinge like the 1752 puts the closing force in the hinge itself, so nothing hangs on the door face and nothing projects into the opening. That is what you want on apartment entry doors, stairwell doors and back-of-house openings where a surface closer would be vandalised or would look wrong. What it does not give you is controlled sweep and latch speed, backcheck, or delayed action. If the opening needs a measured closing cycle or ADA-tuned opening force, a closer is the correct product. The 1752 also tops out at a 70 lb door.
11) What finishes and sizes can I get the Hager 1752 in?
Nine finishes, each available in both 3-1/2 x 3-1/2 and 4 x 4 inch: 605 Bright Brass, 609 Antique Brass, 619 Satin Nickel, 625 Bright Chrome, 626 Satin Chrome, 10R Antique Bronze, AN Antique Nickel, Dull Black, and 600 Primed for Painting. For a property manager standardising a building, 626 Satin Chrome and 600 Primed are the two that disappear into most existing hardware schedules, and the primed option lets you match a painted frame exactly.
12) Is the Hager 1752 spring hinge handed? Do I order left or right?
No handing to specify on the 1752. It is a single-acting full mortise butt hinge with three knuckles, so the same hinge goes on a left hand or right hand door, and the spring is adjusted after it is hung. What you do specify is size (3-1/2 x 3-1/2 or 4 x 4) and finish.
13) My spring hinge door will not latch. Is that the hinge or something else?
Usually it is tension against a load the hinge is fighting. Hager flags strong wind, drafts, carpet drag, and twisted or misaligned doors as the conditions that defeat a spring hinge. Before adding tension, check that the door is not binding in the frame and that the carpet pile is not catching the bottom rail. Then bring the tension up a notch at a time. If the door is over the 70 lb rating, no amount of tension fixes it and you want a closer.
14) Can I get a spring hinge that stays hidden when the door is closed?
The 1752 is a visible butt hinge, so both leaves and the barrel show on the edge of the door. If the design calls for nothing visible, SOSS builds invisible spring closer hinges: the 216IC Series and 220IC Series both carry a 20 minute fire rating, and the 218IC is a 7 inch heavy duty unit needing a minimum 1-3/4 inch door thickness. The 220IC is 7 inch and needs a 2 inch minimum door thickness, so check your door before specifying.
15) What is the difference between the Hager 1752 and a SOSS invisible spring closer hinge?
The SOSS 216IC and SOSS 220IC are invisible spring closer hinges carrying a 20 minute fire rating, both heavy duty, and the SOSS 218IC is a 7 inch heavy duty invisible spring closer requiring a minimum door thickness of 1-3/4 inches. Invisible hinges mortise into the edge of the door and frame and are not visible when the door is closed. The Hager 1752 is a conventional full mortise leaf spring hinge in medium duty with a 5/8 inch radius corner and a 3 knuckle barrel that shows on the door edge. Choose by whether the hinge is meant to be seen and by the duty level the opening calls for.
16) Is there a 5/8 inch radius spring hinge that matches a Z hole pattern instead of standard hole spacing?
The Orca Hardware SPR4058Z is a 4 inch by 4 inch 5/8 inch radius corner spring hinge with a Z hole pattern, medium duty, while the Orca Hardware SPR4058 is the same size and radius with the standard pattern. The Hager 1752 shares the 5/8 inch radius corner and medium duty rating in its 4 inch by 4 inch size. Check the existing screw hole layout in the frame before ordering, since the hole pattern determines whether the leaf lands on the existing holes.
17) I need a UL listed spring hinge for a fire rated opening. Which options work?
For UL listed spring hinges, the Design Hardware UL Spring Hinge is a medium duty UL spring hinge, and the Emtek 95013 is a UL listed plated steel spring hinge pair in 3-1/2 inch by 3-1/2 inch with square corners. The SOSS 216IC and SOSS 220IC are invisible spring closer hinges carrying a 20 minute fire rating in heavy duty. The Hager 1752 is a BHMA Grade 1 certified commercial spring hinge under ANSI K81071F in medium duty. Confirm the listing requirement on the door label before selecting, since corner style and size still have to match the frame prep.
18) Can I mix plain bearing spring hinges like the BEST 2060R with the Hager 1752 on the same door?
Hager advises using all spring hinges or a combination of spring hinges and ball bearing hinges, and specifically not to use plain bearing hinges alongside the 1752. The BEST 2060R and BEST RD2060R are both plain bearing spring hinges, so they are better treated as a full replacement set for an opening rather than mixed in with the 1752 on the same door. If a door needs one spring hinge and one non-spring hinge, pair the 1752 with a ball bearing hinge.
19) What material is the Hager 1752 and how thick is the leaf?
Steel, 0.097 gauge, standard weight. That is the medium-duty class of leaf, which is what you want on interior commercial doors in the 45 to 70 lb range. Where the opening is exterior or exposed to moisture, steel with a plated finish will need watching; a stainless product is the safer choice for wet locations.
20) Where do the hinges go on the door? Is there a template?
Hager publishes standard hinge location guidance and installation documentation with the 1752, and the hinge is installed to manufacturer templates with the mortise pockets routed to accept the 5/8 inch radius corners on both door and frame. Mark from the template rather than the old holes if you are changing hinge size, since 3-1/2 and 4 inch leaves do not share a screw pattern.
