Hager 1754426D – Frequently Asked Questions

1) Will a Hager 1754 spring hinge close the door by itself, or do I still need a door closer?
The 1754 is a self-closing full mortise spring hinge, so on a door in its range it pulls the door shut without a separate closer. It is rated for door weights of 45 to 75 lbs at a medium duty level. Spring tension is set during installation, and a few site conditions eat into it: wind, drafts through the opening, and carpet drag at the bottom of the door all slow the swing. If the opening sees any of those, or the door is heavier than 75 lbs, a closer is the right call instead.
2) My door and frame are prepped with 5/8 inch radius corners - will the Hager 1754 drop into that mortise?
Corner style on the 1754 is 5/8 inch radius by square corners, so it pairs one square corner leaf with one 5/8 inch radius leaf. That covers an opening where the machine-routed side takes the 5/8 inch radius and the other side is a square-corner mortise. If both your door and frame are cut with 5/8 inch radius on both leaves, the Orca Hardware 4058 Series 4 x 4 inch 5/8 inch radius corner spring hinge matches that prep, and the Orca 4040 Series is the square corner version for a prep that is square on both sides. For a 1/4 inch radius prep, the Orca 4014 Series is the 4 x 4 inch 1/4 inch radius spring hinge.
3) My door is heavier than 75 lbs - can I still use these spring hinges?
No. The 1754 is built for doors between 45 and 75 lbs at a medium duty rating, and past that the spring will not pull the door closed reliably or hold up over time. Heavy duty spring closer options in our line are the SOSS 218IC (7 inch, 1-3/4 inch minimum door thickness) and the SOSS 220IC (7 inch, 2 inch minimum door thickness), both invisible spring closer hinges. Those are a completely different prep, mortised into the door edge and frame rather than a butt hinge cutout, so confirm the door edge can take them before you spec one.
4) The doors are prepped for square corner hinges with no radius - what spring hinge fits that mortise?
The Hager 1754 is cut with 5/8 inch radius by square corners, so a pocket routed with true square corners leaves a gap at the corners. For that prep, the Orca Hardware SPR4040 is a 4 inch by 4 inch square corner spring hinge in medium duty, the same 4 inch by 4 inch leaf size. The BEST 2060R is another square corner standard weight spring hinge rated medium duty, and it comes with a removable pin. On new work where the router is not yet set, either corner style can be specified, but on a replacement the corner radius has to match what is already cut.
5) What is a direct replacement for a Hager 1754 4 inch by 4 inch spring hinge with 5/8 inch radius corners?
The Hager 1754 is a steel full mortise spring hinge with 5/8 inch radius by square corners in a 4 inch by 4 inch size, rated medium duty. The Orca Hardware SPR4058 matches that geometry directly - it is a 4 inch by 4 inch by 5/8 inch radius corner spring hinge, also medium duty, so it seats in a pocket already routed for the 5/8 inch radius without recutting the door or frame. Orca also builds the SPR4058Z, the same 4 inch by 4 inch 5/8 inch radius corner spring hinge with a Z hole pattern, which is the one to pull when the screw holes in the existing prep follow that layout instead of the standard one.
6) The door schedule calls out a UL listed spring hinge - which ones carry that listing?
The Hager 1754 is certified ANSI K81071F for commercial use. Where the specification names UL listing on the spring hinge itself, the Emtek 95013 is a UL listed spring hinge in plated steel, 3-1/2 inch by 3-1/2 inch with square corners, supplied as a pair, and Design Hardware builds a UL spring hinge rated medium duty. On concealed applications, the SOSS 216IC and 220IC invisible spring closer hinges carry a 20 minute fire rating. Verify the size and corner cut against the door prep before substituting, since the Emtek is a 3-1/2 inch leaf.
7) Can a SOSS invisible spring closer hinge be used in place of a 4 inch full mortise spring hinge?
They both self-close, but they are not interchangeable hardware. The Hager 1754 is a 3 knuckle full mortise spring hinge with visible leaves that seat in a 4 inch by 4 inch mortise. The SOSS 216IC, 218IC and 220IC are invisible spring closer hinges rated heavy duty, and they carry door thickness minimums - 1-3/4 inch on the 218IC and 2 inch on the 220IC, which is a 7 inch hinge. The SOSS units also have fire ratings on the 216IC and 220IC at 20 minutes. Choose the invisible closer when nothing may show on the closed door and the door is thick enough; choose a 4 inch by 4 inch leaf hinge when the opening is already routed for one.
8) How many Hager 1754 spring hinges do I need per door, and do screws come with them?
They come as a 2-pack with screws, which is the usual quantity for one door. Common practice is to hang the door on standard butt hinges and use spring hinges in place of one or two of them rather than all three. When you do run more than one spring hinge on the same door, they do not all need to be wound to full tension, so set them together until the door closes and latches at a controlled speed. No separate fastener order is needed for a standard wood or hollow metal prep.
9) I need self-closing hinges that match the satin chrome hardware already on my other doors - what does the Hager 1754 come in?
Seven finishes: 626 Satin Chrome, 625 Bright Chrome, 606 Satin Brass, 605 Bright Brass, 10R Antique Bronze, Dull Black, and 600 Primed for Painting. Satin chrome (626) is the one that matches most commercial lever and closer hardware. The primed option is worth knowing about if you are painting hinges to match frames across a building, since it takes paint without stripping a plated finish first. The hinge is a 3-knuckle steel butt, so it reads the same as the standard hinges on the rest of the openings.
10) Does the Hager 1754 spring hinge meet a BHMA standard for a commercial hardware spec?
It carries ANSI K81071F and is BHMA Grade 1 certified, and it is classified for commercial use rather than residential only. Construction is steel at 0.097 inch gauge, standard weight, full mortise, with 3 knuckles. That combination is what a specifier or facilities buyer needs on a submittal for interior openings: a certified self-closing hinge rather than an uncertified spring hinge, at a medium duty level.
11) What self-closing hinge should I use on a door that has to swing both directions?
A 4 inch by 4 inch full mortise spring hinge such as the Hager 1754 carries the door in one swing direction, the way the Deltana DSH35R4 is described as single action. For a door that swings both ways, Deltana makes the DASH95 double action spring hinge with solid brass cover plates and the DASHS double action saloon hinge, sold each in 4 inch, 5 inch and 6 inch heights. Those mount as double action hardware rather than dropping into a standard butt hinge mortise, so the door and jamb prep is different work.
12) Which spring hinge has a removable pin so the door can be taken off without unscrewing the leaves?
The Hager 1754 is a 3 knuckle standard weight full mortise spring hinge. Where crews need to lift doors off repeatedly - turnover work, moving equipment through rooms - the BEST RD2060R is a plain bearing spring hinge with a removable pin in a radius corner, standard weight and medium duty, which is the closer corner match to the 5/8 inch radius cut on the Hager 1754. The BEST 2060R is the square corner version of the same removable pin standard weight spring hinge, also medium duty.
13) What is the spring hinge equivalent for a 3-1/2 inch by 3-1/2 inch door prep?
The Hager 1754 covers the 4 inch by 4 inch opening and ships as a 2 pack with screws. Stepping down to a 3-1/2 inch prep, the Deltana DSH35R4 and DSH35R4-A are single action spring hinges measuring 3-1/2 inch by 3-1/2 inch with a 1/4 inch radius in steel, and the Emtek 95013 is a 3-1/2 inch by 3-1/2 inch square corner spring hinge in plated steel, UL listed and sold as a pair. Pick by the corner cut in the door: the Deltana pieces are radius corner, the Emtek is square.
14) Which spring hinges do you carry that have a fire rating or UL listing stated?
Two in our line publish that. The SOSS 216IC Series invisible spring closer hinge lists a 20 minute fire rating, and the SOSS 220IC Series does as well at 7 inches with a 2 inch minimum door thickness; both are heavy duty. Design Hardware also builds a UL spring hinge at a medium duty level. For a labeled opening, the hinge is only part of it, so match it to the rest of the listed assembly on that door.
15) Is a spring loaded continuous hinge an alternative to a pair of 4 inch spring hinges?
They serve different openings. The Hager 1754 is a 4 inch by 4 inch full mortise spring hinge supporting 45 to 75 lbs of door weight, set at the standard hinge locations on the door edge. The Pemko Markar FM400 and FM900 series and the Pemko FS402 and FS902 series are spring loaded continuous hinges built for toilet partitions with 80 lb load capacity, running the height of the panel rather than mounting as two or three separate leaves; the FM400 is a full mortise version and the FS902 is 304 stainless steel. Specify continuous where the application is a partition door or where stainless is required; specify a 4 inch by 4 inch leaf hinge where the door is already mortised for butt hinges.
