Orca Hardware 4" x 4" x 5/8" Radius Corner Spring Hinge

It is a medium duty steel hinge, which covers apartment unit doors, office interiors, and light traffic commercial openings. Steel is the base material, so it is not a wet or coastal exterior hinge. For a high traffic entrance or a heavy solid core door, step up to a heavy duty product; the SOSS 216IC and 218IC invisible spring closer hinges are the heavy duty spring options we carry.

No. The 4058 is not ADA compliant, so it should not be specified where the opening has to meet accessibility requirements for opening force and closing speed. On those doors, use a closer that can be adjusted and verified against the required force, and keep the spring hinge for back of house, storage, and utility openings.

The 4058 will not sit right in a square corner mortise, since it is cut with 5/8 inch radius corners. For square corner prep we carry the BEST 2060R plain bearing spring hinge with removable pin in square corners, and the McKinney 1502 square corner full mortise spring hinge in 4-1/2 by 4-1/2. If your prep is a smaller 1/4 inch radius, the Hager 1251 is the 1/4 inch round corner spring hinge and the Deltana DSH35R4 is a 3-1/2 by 3-1/2 with a 1/4 inch radius.

The Hager 1252 is the direct counterpart, a full mortise spring hinge with 5/8 inch round corners in standard weight steel, same medium duty class. The BEST RD2060R is another radius corner spring hinge in that duty range and adds a removable pin, which matters if you want to lift the door off without unscrewing leaves. If you are matching an existing building standard, pick on corner radius and leaf size first, then finish.

The Orca 4058 is cut with 5/8 inch radius corners, so it will not sit flush in a square corner mortise. For a square corner prep, the Hager 1250 is a full mortise standard weight steel spring hinge with square corners at the same medium duty level. The McKinney 1502 is also a square corner full mortise standard weight spring hinge, sized 4-1/2 by 4-1/2 inches, which suits a prep cut for the larger leaf. The BEST 2060R is a square corner standard weight spring hinge with a removable pin, useful when the door has to come off the frame without disturbing the hinge leaves.

The Orca 4058 is a medium duty spring hinge, matching the Hager 1150, Hager 1250 and McKinney 1502 class. Where the leaf is heavier or the opening cycles harder, the SOSS 216IC, 218IC and 220IC invisible spring closer hinges are heavy duty. Those three mortise fully into the door and frame edge rather than mounting as a visible butt, so the swap is not leaf-for-leaf: the 218IC is 7 inches and needs a minimum door thickness of 1-3/4 inches, and the 220IC is 7 inches with a 2 inch minimum door thickness.

The Orca 4058 is a single action spring hinge, closing the door in one direction. The Deltana DASH95 and DASHS are double action hinges, meaning the door swings and self-centers both ways, and the DASHS is sold each in 4, 5 and 6 inch heights as a saloon hinge. Those belong on a two-way opening, not on a jamb prepped for a conventional single-swing butt. For a single action steel spring hinge in a smaller size, the Deltana DSH35R4 and DSH35R4-A are 3-1/2 by 3-1/2 inches with a 1/4 inch radius, which is a different mortise footprint and corner radius from the 4 by 4 inch, 5/8 inch radius Orca 4058.

A spring hinge is a self-closing hinge, so the closing force lives inside the hinge barrel instead of on an arm mounted across the top of the door. The Orca 4058 replaces a standard butt hinge in the same mortise, which keeps the opening clean with nothing visible on the face of the door or the frame. That is why they get used on apartment unit doors, stairwell doors, and utility rooms where a surface closer would be in the way or would look wrong. A surface closer is the better choice when you need controlled sweep and latch speed, backcheck, or a hold-open, because a spring hinge gives you closing force and nothing else.

No. The 4058 is a full mortise butt style spring hinge, and spring hinges of this type are non-handed; the spring tension is adjusted after the hinge is mounted, so the same part works on a left hand or right hand door. The only thing you choose is the finish, which comes in Satin Nickel, Matte Black, or Oil-Rubbed Bronze.

A single action spring hinge like the Orca 4058 swings one way and pulls the door closed, which is what you want on a unit door, stairwell, or utility room. A double action hinge swings both directions, and that is a different job: kitchen pass-throughs, stockroom doors, saloon style openings. We carry the Deltana DASH95 double action spring hinge with solid brass cover plates and the Deltana DASHS double action saloon hinge in 4, 5, and 6 inch heights for those. Do not substitute one for the other; the door frame stop alone decides whether a double action hinge can work.

Yes. The BEST RD2060R is a spring hinge with a removable pin in a plain bearing radius corner standard weight configuration, and it shares the medium duty level of the Orca 4058. The removable pin lets the door leaf be lifted off without unscrewing the hinge from the jamb, which matters on turnovers where the same opening gets pulled repeatedly. The Orca 4058 is a steel spring hinge in satin nickel, matte black, and oil-rubbed bronze, so the choice between them is a decision about pin removability and finish rather than about corner style.

The Orca 4058 is a steel spring hinge. Where the substrate needs to be stainless, the Hager 1150 is a full mortise spring hinge in standard weight stainless steel at the same medium duty level, and the Pemko Markar FS902 series is a spring loaded continuous hinge in 304 stainless steel. Stainless is the usual call on exterior openings, coastal sites, and wash-down or high-humidity areas such as locker rooms and kitchens.

The Orca 4058 is a conventional butt-style spring hinge, so the barrel and leaves show on the door edge when it is open. For a concealed look, the SOSS 216IC, 218IC and 220IC are invisible spring closer hinges: they mortise into the door and frame edges and disappear when the door is shut. All three are heavy duty, the 216IC and 220IC series carry a 20 minute fire rating, and the 218IC and 220IC are 7 inch hinges requiring minimum door thicknesses of 1-3/4 inches and 2 inches. That thickness requirement is the first thing to check, since a thinner door rules them out.

The Orca 4058 covers the 4 by 4 inch preps with 5/8 inch radius corners. For the 3-1/2 inch openings, the Deltana DSH35R4 and DSH35R4-A are 3-1/2 by 3-1/2 inch single action steel spring hinges with a 1/4 inch radius, and the Emtek 95013 is a 3-1/2 by 3-1/2 inch UL listed plated steel spring hinge with square corners sold in pairs. Match the corner style to what is already cut in each jamb, since radius and square preps are not interchangeable without rework.

Three: Satin Nickel, Matte Black, and Oil-Rubbed Bronze. That set matches the finishes most commonly running on residential and light commercial lever trim, so if you are standardizing a building on matte black hardware the hinge will follow. There is no plain brass or chrome option in the 4058.
