Orca Hardware 4" x 4" x 5/8" Radius Corner Spring Hinge, Z Hole Pattern

That is what these are for. The spring lives in the hinge barrel, so the door self closes with no closer body or arm on the face of the door, which is why property managers use them on unit and stairwell doors where a surface closer would get abused or removed. The tradeoff: closing force is fixed by the spring tension you set at install, and there is no separate latching or backcheck adjustment the way a closer gives you. The SPR4058 is not ADA compliant, so on an opening that has to meet accessible opening force requirements, a closer is the right call instead.

Use a UL listed spring hinge on a labeled opening. The Design Hardware UL spring hinge and the Emtek 95013 pair (3-1/2 x 3-1/2, square corners, UL listed, plated steel) are the listed options to look at, and the SOSS 216IC and 220IC invisible spring closer hinges carry a 20 minute fire rating for concealed applications.

The Orca SPR4058 is a 4 x 4 hinge, so it will not fit a 3-1/2 inch prep. In that size, Deltana's DSH35R4 and DSH35R4-A are single action steel spring hinges at 3-1/2 x 3-1/2 with a 1/4 inch radius, and the Emtek 95013 is a 3-1/2 x 3-1/2 square corner pair in plated steel. Match the corner radius of your existing prep when you pick between them.

Yes. The Hager 1251 is a full mortise spring hinge with 1/4 inch round corners in standard weight steel, and the Deltana DSH35R4 is a single action spring hinge with a 1/4 inch radius in steel at 3-1/2 by 3-1/2 inches. The Orca SPR4058 is cut at a 5/8 inch radius, so on a 1/4 inch prep the 1251 keeps the same steel standard weight construction while matching the corner cut, and the Deltana DSH35R4 suits a smaller 3-1/2 inch mortise.

The Hager 1252 full mortise spring hinge is built with 5/8 inch round corners in standard weight steel, matching both the corner profile and the steel construction of the Orca SPR4058, which is a steel spring hinge with 5/8 inch radius corners. Corner radius has to match the mortise already routed in the door and frame, so a 5/8 inch radius hinge is the direct answer when the existing prep is cut that way. Both are rated medium duty.

Single acting spring hinges of this kind mount to either hand, since the leaf is symmetrical and the spring tension is set with a pin and tension key after the hinge is hung. What you do have to get right is orientation of the barrel and setting equal tension on every spring hinge in the opening. The Z hole pattern on the SPR4058 is the screw layout in the leaf, not a handing designation.

Medium duty is the rating, and steel is the material. That suits interior commercial and multi family openings, unit entries, stairwell and corridor doors within the 3 ft by 7 ft and 110 lb envelope. For a high traffic or heavier opening, the SOSS 218IC and 220IC invisible spring closers are the heavy duty options, and the Pemko continuous spring hinges spread load over the full height of the door.

Order by hinge count, because the weight rating is per opening based on how many springs you hang: one spring for up to 60 lb, two for up to 85 lb, three for up to 110 lb. Most doors also carry non spring hinges alongside the spring units, so count the total hinge openings on the frame and decide how many of those get a spring. If you want a pair packaged together in a smaller size, the Emtek 95013 is a 3-1/2 x 3-1/2 pair.

Single action, which is what the Orca SPR4058 is, swings the door one direction and springs it back to the closed position against a stop. Double action lets the door swing both ways and centers it, which is what you want on a kitchen, stockroom, or saloon style opening with no rabbeted stop. If both ways is what you need, Deltana's DASH95 double action spring hinge with solid brass cover plates and the DASHS double action saloon hinge in 4, 5, and 6 inch heights are the ones to look at.

Yes. The BEST RD2060R is a spring hinge with a removable pin in a plain bearing radius corner standard weight build, and the BEST 2060R is the same removable pin plain bearing spring hinge in square corners. Both are medium duty, the same duty rating as the Orca SPR4058. For unit turns where doors come off repeatedly, the removable pin versions save pulling the hinge from the frame; pick the RD2060R for radius corner prep and the 2060R for square.

Not as a drop-in. The Pemko Markar FM400 and FM900 series are full mortise spring loaded continuous hinges rated to 80 lb built for toilet partitions, and the Pemko FS402 and FS902 series are spring loaded continuous hinges for the same application, with the FS902 in 304 stainless steel. A continuous hinge runs the full height of the leaf and needs edge prep along that whole length, where the Orca SPR4058 drops into two or three individual 4 by 4 inch mortises. Choose by prep, not by capacity alone.

Both are full mortise spring hinges in standard weight and both are medium duty. The Hager 1150 is stainless steel and the Hager 1250 is steel construction, which is the same substrate as the Orca SPR4058. On exterior or wet locations the stainless 1150 is the one commonly specified; where the rest of the openings are already steel spring hinges, the 1250 keeps the material consistent across the fleet.

The SOSS 216IC, 218IC and 220IC are invisible spring closer hinges, concealed in the edge of the door and frame so nothing shows on the face when the door is shut. All three are heavy duty. The Orca SPR4058 is a surface visible butt hinge and is finished to suit, offered in oil-rubbed bronze, satin nickel, matte black and polished chrome. For millwork and flush panel doors where no hardware should read, the invisible SOSS hinges are the pattern; the 218IC needs a 1-3/4 inch minimum door thickness and the 220IC a 2 inch minimum.

Four finishes: oil rubbed bronze, satin nickel, matte black, and polished chrome. That is the full range, so if you are matching existing lever and deadbolt hardware across a building, one of those four is what you standardize on. The hinge itself is steel.

Plan on removing the door by unscrewing the leaves rather than dropping a pin. If pulling the leaf without unscrewing matters on your job, the BEST 2060R and BEST RD2060R are spring hinges built with a removable pin, the RD2060R being the radius corner version.
