SOSS 220IC Invisible Spring Closer Hinge

The SOSS 220IC Invisible Hinge is a 7" spring closer hinge engineered for doors with a 2" minimum material thickness. Constructed of zinc and steel with nylon links for added strength and durability, this Underwriters Laboratories labeled hinge carries a 20 minute fire rating for use on hollow metal, sheet metal, tin clad, steel composite, or wood core swinging fire doors and frames. Totally invisible from either side when the door is closed, the 220IC combines the function of a hinge and self-closing device in a single, concealed unit suited for full sized entry applications on metal or wood doors.

Key Features

  • Door Thickness Compatibility: Designed for doors with a 2" minimum material thickness, ideal for full sized entry, metal, and wood door applications.

SOSS 220ICUS26D – Frequently Asked Questions

1) Will a SOSS 220IC invisible spring hinge work on a standard 1-3/4 inch commercial door?
No. The 220IC needs a door with 2 inches minimum material thickness, and a 1-3/4 inch door does not have the material to bury the hinge body in. For a 1-3/4 inch opening, go to a conventional full mortise spring hinge instead, such as the Hager 1250 or the McKinney 1502 in 4-1/2 by 4-1/2 inch. Those cut into the door edge and the frame rebate rather than hiding inside the door's thickness, so door thickness is not the limiting factor.
2) What is the difference between a SOSS 220IC invisible spring closer hinge and a full mortise spring hinge like the Hager 1250?
The SOSS 220IC is a 7 inch invisible spring closer hinge that is concealed inside the door or the jamb and is not visible from either side when the door is closed, so it carries the door and closes it in one hidden unit. The Hager 1250 is a full mortise spring hinge in steel construction, mortised into the door edge and frame with its barrel visible in the gap. The 220IC is rated heavy duty and is built from zinc and steel with nylon links; the Hager 1250 is rated medium duty. The choice usually comes down to whether the opening needs the closer hidden for sightlines and whether the door has the material depth to bury the 220IC body.
3) The SOSS 220IC needs a 2 inch minimum door thickness. What self closing hinge works on a thinner door?
The SOSS 220IC is engineered for doors with a 2 inch minimum material thickness because the spring closer body is buried inside the door or the jamb. When the door does not have that depth, a full mortise spring hinge keeps the self closing function without needing concealed material: the Hager 1250 in steel construction, the Hager 1150 in stainless steel, and the McKinney 1502 square corner full mortise at 4-1/2 by 4-1/2 inches are all full mortise spring hinges in medium duty. These mount into a standard hinge mortise in the door edge and frame rather than into the body of the door.
4) Can the SOSS 220IC invisible hinge be mortised into the jamb instead of the door?
Either one. The 220IC installs inside the door itself or inside the door jamb, whichever suits the prep you can cut, and it swings a full 180 degrees as a single action hinge. Closed, nothing shows on the push side or the pull side. The door still has to carry 2 inches minimum material thickness, and the hinge is a 7 inch size, so confirm you have that much depth and length of solid material to route into before you commit to the location.
5) Do SOSS 220IC hinges come with screws, and are they sold as a pair or singly?
One hinge per box, not a pair, and both wood and machine screws are included so the same box covers a wood door or a metal one. Work out the quantity before you order rather than assuming two or three: one closer per 55 lbs of door weight or portion thereof, and on a fire rated door one hinge per 20 inches of door height or fraction thereof, with the larger of the two figures being the number of pieces you buy.
6) Can you adjust the closing speed on a SOSS 220IC after the door is already hung?
Yes, and the closer stays in the door while you do it. The closure rate on the 220IC is fully adjustable with an allen wrench once the hinge is installed, so you can set the swing with the door hanging and come back and re-tune it later without pulling the unit out of the mortise.
7) Will a SOSS 220IC invisible spring hinge work on toilet partition doors?
No. The 220IC wants 2 inches minimum material thickness and is built for full sized entry doors in metal or wood, which is not what a partition door gives you. For restroom partitions, the Pemko Markar FM400 and the Pemko FS402 series spring loaded continuous hinges are the ones made for that application, both carrying an 80 lb load capacity.
8) I need a spring hinge with radius corners to drop into an existing door prep. Which ones come in radius corner?
The SOSS 220IC is a radius corner spring hinge, but it is a concealed unit rather than a surface mortise leaf. If the prep in the door and frame calls for a mortise leaf with a specific corner radius, the corner size has to be matched exactly. The Hager 1251 has 1/4 inch round corners and the Hager 1252 has 5/8 inch round corners, both full mortise spring hinges in steel; the Hager 1250 is the square corner version of the same full mortise spring hinge. Orca Hardware splits the same way at 4 by 4 inches: SPR4014 with a 1/4 inch radius corner, SPR4058 with a 5/8 inch radius corner, and SPR4040 with a square corner. The BEST RD2060R is a radius corner spring hinge with a removable pin, and the Deltana DSH35R4 is a 3-1/2 by 3-1/2 inch steel single action spring hinge with a 1/4 inch radius.
9) Can a Deltana DASH95 or DASHS double action hinge replace a SOSS 220IC?
No, they swing differently. The SOSS 220IC is a single action hinge that opens a full 180 degrees in one direction and returns the door closed. 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 directions and centers itself, which is the behavior wanted on a cafe or pass through opening rather than on a full sized entry door that must latch on one side. If the opening is an entry door that has to close against a stop and a frame, the double action hinges are not an equivalent.
10) Are the Pemko spring loaded continuous hinges an alternative to a SOSS 220IC on an entry door?
They are built for a different opening. The SOSS 220IC is a 7 inch concealed spring closer hinge for full sized entry, metal, and wood door applications, applied in the quantity the door weight calls for at one closer per 55 pounds of door weight or portion thereof. The Pemko Markar FM400 and FM900 and the Pemko FS402 and FS902 are spring loaded continuous hinges for toilet partitions with an 80 pound load capacity, the FS902 in 304 stainless steel and the FM400 in a full mortise pattern. A continuous hinge runs the height of the leaf and is specified against that 80 pound partition door capacity, so it does not stand in for the 220IC on a full sized entry door.
11) Which self closing hinge lets me lift the door off without unscrewing the hinge, unlike the SOSS 220IC?
The SOSS 220IC is a concealed unit fastened inside the door or the jamb with the supplied wood and machine screws, and its closure rate is adjusted in place with an allen wrench rather than by pulling the closer. For a spring hinge with a removable pin, the BEST 2060R is a plain bearing spring hinge with a removable pin in square corners, standard weight, and the BEST RD2060R is the radius corner version of the same plain bearing removable pin spring hinge. Both are medium duty. The removable pin lets the door leaf come off the frame leaf without disturbing the screws, which matters where doors are pulled repeatedly for painting or unit turns.
12) How many hinges do I have to buy compared with spring hinges that ship as a pair?
Quantities are counted differently across brands, so it is worth checking before the order goes in. The SOSS 220IC is packaged one per box, one each, and the quantity is driven by the door: one closer for every 55 pounds of door weight or portion thereof, and on fire rated assemblies one fire rated hinge for every 20 inches of door height or fraction thereof, with the larger of the two calculations governing. The Emtek 95013 is sold as a pair of 3-1/2 by 3-1/2 inch spring hinges, so one order line covers two hinges. The Deltana DASHS saloon hinge is sold each. Counting a pair as one hinge, or one hinge as a pair, is the most common way these orders come up short on site.
13) Is a Design Hardware UL spring hinge the same thing as a SOSS 220IC for a fire door?
They are different hinge types serving the same self closing requirement. The SOSS 220IC is an Underwriters Laboratories labeled invisible spring closer hinge carrying a 20 minute fire rating for hollow metal, sheet metal, tin clad, steel composite, and wood core swinging fire doors and frames, and it is rated heavy duty. The Design Hardware UL Spring Hinge is a medium duty spring hinge, and the Emtek 95013 is a UL listed spring hinge in plated steel sold as a pair at 3-1/2 by 3-1/2 inches with square corners. Where the assembly is being built to a labeled fire door specification, confirm the hinge label matches the rating on the door before substituting.
14) Is the SOSS 220IC heavy duty enough for a high traffic commercial entrance?
It is rated heavy duty and built for commercial service, zinc and steel construction with nylon links in the linkage for added strength. That is a tier above the medium duty full mortise spring hinges in the same category, such as the BEST 2060R or the Orca Hardware 4058 series radius corner hinge. If the opening is a main entry that cycles all day, the heavy duty rating plus the per-55 lb closer count is what keeps the door closing properly.
15) Does the SOSS 220IC need power, and can I run access control wiring through it?
Purely mechanical. There is no electronic version of the 220IC and no power transfer through the hinge, so the door keeps closing itself whether or not the building has power. If you need wire into the door leaf for an electric lock, a request-to-exit device or a monitored contact, that has to come through a separate electric hinge or a door loop on the opening.
16) What finishes does the SOSS 220IC come in, and does the finish even show?
Five: 613L oil rubbed bronze lacquered, 619 satin nickel, 625 bright chrome, 626 satin chrome and 606 satin brass. Because the hinge is hidden completely when the door is closed, the finish only reads on the edge of the door while it stands open, so matching the rest of the trim on the opening carries less weight here than it would on an exposed butt hinge. Pick the closest match to the lever and stop there.
17) The SOSS 220IC is zinc and steel. What spring hinge comes in stainless steel?
The SOSS 220IC is built from zinc and steel with nylon links. Among full mortise spring hinges, the Hager 1150 is a standard weight stainless steel full mortise spring hinge, while the Hager 1250 is the same full mortise spring hinge in steel construction, and both are medium duty. In continuous hinge form, the Pemko Markar FS902 is 304 stainless steel. Material is usually the deciding factor on exterior openings, wash down areas, and coastal work where the specification calls out stainless.
18) What is the difference between the Orca SPR4058 and the SPR4058Z spring hinges when cross referencing a SOSS 220IC job?
Both are 4 by 4 inch spring hinges with a 5/8 inch radius corner in medium duty, and the difference is the fastener layout: the SPR4058Z carries a Z hole pattern while the SPR4058 does not. That distinction decides whether the hinge lines up with the screw holes already drilled in the door and frame. It has no bearing on the SOSS 220IC itself, which is a concealed 7 inch spring closer fitted inside the door or jamb rather than into a surface hinge prep, so a job that switches between the two is redrilling either way.
