Hager EC1105 4.5X4.5 US26D – Frequently Asked Questions

1) How many Hager EC1105 spring hinges do I need per door?
Count depends on door weight and whether the opening is labeled. On a labeled opening, use three EC1105 spring hinges plus one ball bearing hinge. For doors between 150 and 180 lbs, use four spring hinges. Strong wind, drafts, carpet drag, a twisted or misaligned frame, or weatherstripping all add closing resistance, so those openings may need an additional spring hinge beyond the base count.
2) Will the Hager EC1105 spring hinge work on a 1-3/8 inch door?
No. The EC1105 is specified for 1-3/4 inch doors, which is the standard commercial door thickness. A 1-3/8 inch door is the common older interior thickness and is outside what this hinge is set up for, so you would be looking at a different spring hinge for that opening.
3) What size and finishes does the Hager EC1105 spring hinge come in?
One size, 4-1/2 by 4-1/2 inches with square corners, in three finishes: 605 bright brass, 613 satin bronze oil-rubbed, and 626 satin chrome. If the other hinges in your building are 4-1/2 inch square corner, this drops into the same prep. Doors prepped for radius corner hinges need a radius corner hinge instead, or the mortise corners re-cut.
4) What is the closest equivalent to a Hager EC1105 spring hinge in a 4-1/2 inch square corner size?
The McKinney 1502 spring hinge is the nearest match: it is a square corner, full mortise, standard weight spring hinge in 4-1/2 by 4-1/2 inches, the same size and corner style the EC1105 is offered in, and it carries the same medium duty rating. The EC1105 differs in bearing arrangement, running on ball bearings, and is built with a 5-knuckle steel barrel. If the existing openings are prepped for a 4-1/2 inch square corner mortise, both drop into the same pocket without reworking the door or frame.
5) What is the difference between a ball bearing spring hinge and a plain bearing spring hinge like the BEST 2060R?
The BEST 2060R is a plain bearing spring hinge with a removable pin, square corners, standard weight, and a medium duty rating. The Hager EC1105 is a ball bearing spring hinge, also medium duty, with a 5-knuckle steel barrel. The bearing type is the operating difference: ball bearings sit between the knuckles to carry the load, while a plain bearing runs metal on metal. The removable pin on the 2060R also means the leaves separate at the pin, which matters when doors get pulled for painting or turnover work. For a radius corner frame prep, BEST offers the RD2060R, the same plain bearing standard weight hinge with radius corners.
6) The frames have radius corner hinge pockets, not square. What spring hinge fits instead?
The EC1105 is a square corner hinge, so it will not seat cleanly in a radius corner mortise. For radius prep, Orca Hardware makes a 4 by 4 inch spring hinge in both 1/4 inch radius corner (SPR4014) and 5/8 inch radius corner (SPR4058), and BEST makes the RD2060R, a radius corner standard weight spring hinge with a removable pin. Match the radius to what is already routed in the frame - 1/4 inch and 5/8 inch pockets are not interchangeable. All three carry the same medium duty rating the EC1105 does, except the RD2060R which is also medium duty.
7) For a labeled fire door opening, what spring hinges can be used besides the EC1105?
The Hager EC1105 is ANSI K81071F certified and calls for three spring hinges plus one ball bearing hinge on labeled openings. Alternatives carrying their own listings include the Design Hardware UL spring hinge, a medium duty spring hinge, and the Emtek 95013, a UL listed plated steel spring hinge in 3-1/2 by 3-1/2 inch square corner sold in pairs. SOSS also offers the 216IC and 220IC invisible spring closer hinges with a 20 minute fire rating, though those mortise into the door edge rather than the face. Confirm the hinge listing matches the door label duration before ordering.
8) Can I use a spring hinge instead of a door closer to self-close a fire door?
A spring hinge is a self-closing device built into the hinge itself, so it closes the door without a surface closer, arm, or header hardware in the way. That is why it gets used where a closer would be visually intrusive or where there is no room for one. The EC1105 carries ANSI K81071F and on a labeled opening the required set is three spring hinges plus one ball bearing hinge. What it does not give you is the control a closer does, no backcheck, no delayed action, no adjustable sweep and latch speed. If the opening needs controlled closing on a high traffic door, a closer is the better tool; if you need self-closing with nothing showing on the door face, spring hinges do it.
9) Do Hager EC1105 spring hinges come with screws, or do I need to order fasteners separately?
Screws are in the box. Each EC1105 ships with 1-1/4 inch by 12 fasteners, both all machine and all wood, so you are covered for a hollow metal frame and a wood door without a separate fastener order. Both leaves mortise in, so the door and frame need routed pockets before the hinges go on.
10) Is the Hager EC1105 a ball bearing spring hinge or a plain bearing one?
Ball bearing, with a 5-knuckle steel barrel. That matters on a spring hinge because the spring is loading the knuckle every cycle; ball bearings carry that load with less friction and less wear than a plain bearing. Several spring hinges in the same class run plain bearing, including the BEST 2060R and the radius corner BEST RD2060R, both medium duty like the EC1105. If your opening sees heavy daily traffic, the bearing type is the difference worth paying attention to.
11) I need a self-closing hinge but I do not want it visible on the door. What are my options?
A full mortise spring hinge like the Hager EC1105 shows a knuckle barrel on the edge of the door the same as any butt hinge. If you want nothing visible when the door is closed, look at the SOSS invisible spring closer hinges instead: the 216IC and 220IC series carry a 20 minute fire rating, and the 218IC is a 7 inch heavy duty unit for doors 1-3/4 inches thick minimum, while the 220IC needs a 2 inch minimum door thickness. They are heavy duty rather than the EC1105's medium duty class. For a bar or partition opening that swings both ways, neither applies; that is a double action hinge like the Deltana DASH95 or the DASHS saloon hinge.
12) Can I order Hager EC1105 spring hinges as singles, or only in a box?
Both. The EC1105 is ordered per hinge, with a box package of 3 pieces offered as an option at checkout. Since a labeled opening takes three spring hinges plus one ball bearing hinge, and a 150 to 180 lb door takes four spring hinges, work out your per-door count first and buy the ball bearing hinge separately, it is not part of this hinge.
13) Do I have to run every Hager EC1105 spring hinge at full tension?
No, and you usually should not. Spring tension is adjustable on each EC1105, and full tension on every hinge in the set is rarely what a door needs. Set enough tension to close and latch the door reliably, then stop; over-tensioning makes the door hard to pull open and beats up the frame. Doors fighting wind, drafts, carpet drag, weatherstripping, or a twisted frame are the ones that need more, and there the answer is often an additional spring hinge rather than cranking the ones you have.
14) Can I get the Hager EC1105 spring hinge with electric transfer for an access control door?
No. The EC1105 is a non-electronic hinge, so there is no concealed wire transfer through the knuckle. If your opening needs power carried from frame to door for an electric lock or a request-to-exit switch, you need an electric transfer hinge or a separate power transfer device on that opening; the spring hinges can still do the self-closing alongside it.
15) Is a SOSS invisible spring closer hinge a substitute for the Hager EC1105?
They both self-close, but they are not interchangeable in the same opening. The EC1105 is a full mortise butt hinge with both leaves mortised into the door and frame face, 5 steel knuckles on ball bearings, in 4-1/2 by 4-1/2 inch square corner. The SOSS 216IC and 218IC are invisible spring closer hinges, heavy duty, that mortise into the edge of the door and jamb and disappear when the door shuts; the 216IC carries a 20 minute fire rating and the 218IC is a 7 inch unit with a 1-3/4 inch minimum door thickness. Swapping between them means new machining, not a screw-for-screw change.
16) Is a double action saloon spring hinge the same thing as the EC1105?
No, and the swing direction is the reason. 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, 5 and 6 inch heights - double action means the door swings both ways and returns to center. The Hager EC1105 is a single direction full mortise spring hinge that closes a commercial door onto its stop. If the opening needs a door that pushes through in both directions, the EC1105 is the wrong device; if the opening is a latching commercial door, a double action hinge is.
17) What is a smaller 3-1/2 inch spring hinge option when a 4-1/2 inch hinge is oversized for the door?
The Hager EC1105 is offered in 4-1/2 by 4-1/2 inches. For a lighter door with a narrower stile, the Emtek 95013 is a 3-1/2 by 3-1/2 inch spring hinge with square corners in plated steel, UL listed and sold in pairs, so the square corner prep carries over at the smaller size. Deltana's DSH35R4 is a 3-1/2 by 3-1/2 inch single action steel spring hinge with a 1/4 inch radius corner, for frames routed with a radius rather than a square pocket. Check the stile width and backset before dropping hinge size - the leaf has to sit fully on the door edge.
18) What is the difference between the Orca SPR4058 and SPR4058Z spring hinges when replacing a Hager EC1105?
Both are Orca Hardware 4 by 4 inch spring hinges with a 5/8 inch radius corner and a medium duty rating. The SPR4058Z uses a Z hole pattern, meaning the screw holes are staggered rather than in line, so it will only land on a door and frame drilled for that pattern. The Orca SPR4040 is the square corner 4 by 4 inch version, which is the corner style that matches the EC1105, though the EC1105 is a 4-1/2 by 4-1/2 inch hinge, so the mortise height still differs. Verify existing screw hole layout and mortise size before ordering any of the three.
19) Is the Hager EC1105 spring hinge rated for commercial use or is it a residential hinge?
Commercial. The EC1105 is a medium duty commercial spring hinge in steel, meeting ANSI K81071F, which is the specification a facility group or an institutional buyer will be looking for on a self-closing opening. For light residential work at a smaller 3-1/2 inch size, the Deltana DSH35R4 single action steel spring hinge or the Emtek 95013 UL listed plated steel pair are the 3-1/2 by 3-1/2 options.
