Orca Hardware 4" x 4" x 1/4" Radius Corner Spring Hinge

Corner radius is the curve on the corner of the hinge leaf, and it has to match the router bit used to cut the mortise. The Orca 4014 is a 1/4 inch radius hinge. If your doors were prepped with the larger 5/8 inch radius, a 1/4 inch leaf leaves a visible gap at each corner, and you'd want a 5/8 inch corner hinge like the Hager 1252 instead. Hager's 1251 is the 1/4 inch round corner equivalent.

The 4014 is sized for an 84 inch (7 foot) door height. Standard practice on a self-closing door that tall is three hinges, and with spring hinges at least two of the three need to be spring loaded so there's enough force to pull the door shut and latch it. Hinges are sold individually by finish, so order the count you need per opening.

The 4014 is a medium duty steel hinge, which covers a normal interior wood door on a residential or light commercial opening. It is not the part for a heavy solid core or exterior door on a high traffic entrance, and not for a door where the closing force has to overcome weatherstripping and a heavy panel. For heavier work, a heavy duty spring closer such as the SOSS 218IC is the different class of product.

The 4014 is not ADA compliant, so it should not be specified where an accessible opening force has to be met. On an ADA path of travel you want an adjustable closer you can dial down, not a spring hinge.

No. The Orca 4014 is a single-swing mortise spring hinge with 1/4 inch radius corners. For a door that swings both ways, 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 hinges mount differently from a full mortise butt, so the door and jamb prep is not interchangeable with the 4014.

The Orca 4014 spring hinge is 4 by 4 inch, which is too tall for a 3-1/2 inch prep. The Deltana DSH35R4 is a single action spring hinge at 3-1/2 by 3-1/2 inch with a 1/4 inch radius in steel, which keeps the same 1/4 inch radius corner profile the Orca 4014 uses in the smaller size. The Deltana DSH35R4-A is the same 3-1/2 by 3-1/2 inch 1/4 inch radius steel single action hinge. The Emtek 95013 also comes 3-1/2 by 3-1/2 inch but with square corners.

The Hager 1251 full mortise spring hinge is the nearest match on corner style and duty. The Orca 4014 spring hinge has 1/4 inch radius corners and is rated medium duty, and the Hager 1251 is a full mortise spring hinge with 1/4 inch round corners at medium duty. If the existing mortises in the frame and door were cut for a radius-corner hinge, either one drops into the same prep without routing the corners square.

Go to a square corner spring hinge rather than trying to fit a radius corner leaf into a square mortise. The Hager 1250 is a full mortise spring hinge in steel construction at medium duty, and the McKinney 1502 is a square corner full mortise standard weight spring hinge in 4-1/2 by 4-1/2 inch. The Orca 4014 is a 4 by 4 inch hinge with 1/4 inch radius corners, so on a square-cut mortise the corners leave a visible gap at each end of the leaf.

An invisible spring closer hinge conceals the hardware in the door edge. The SOSS 216IC series is an invisible spring closer hinge with a 20 minute fire rating at heavy duty, the SOSS 220IC series is an invisible spring closer hinge with a 20 minute fire rating in a 7 inch size requiring a 2 inch minimum door thickness, and the SOSS 218IC is a 7 inch heavy duty invisible spring closer hinge with a 1-3/4 inch minimum door thickness. All three are heavy duty, where the Orca 4014 is medium duty, and all require a routed pocket rather than the surface-visible mortise the 4014 uses.

Spring hinges like the 4014 put the closing force inside the hinge, so there's no arm or body on the face of the door and no extra prep beyond the hinge mortise. That's why they get used on apartment unit doors, closets, and stairwell-style residential openings where a surface closer would look wrong. The trade-off: the spring is preloaded with a tension pin, not tuned like a closer, so you get no separate sweep and latch speed control and no backcheck. If you need controlled closing speed or a specific opening force, use a closer.

No. The 4014 is a single action full mortise spring hinge, so the door swings one direction only. For a door that has to push both ways, like a kitchen or bar pass door, you need a double action hinge, such as the Deltana DASHS saloon hinge or the Deltana DASH95 double action spring hinge with brass cover plates.

No. A full mortise spring hinge of this type is non-handed, so the same 4014 goes on a left hand or right hand door. The spring direction is set by which leaf you fasten to the door versus the frame and by how you wind the tension when you install it, so handing is decided on the job, not on the order.

Yes, and it's the normal way these get installed. Because the 4014 is a 4 x 4 full mortise hinge with 1/4 inch radius corners, it shares the same prep as a standard 4 x 4 radius corner butt hinge, so you can swap one or two positions on an existing door to spring and leave the rest as plain butts. Keep the finishes matched and put the spring hinges at the top and bottom positions for the best closing action.

For a removable pin, the BEST RD2060R is a spring hinge with removable pin, plain bearing, radius corner, standard weight at medium duty, and the BEST 2060R is a spring hinge with removable pin, plain bearing, square corners, standard weight at medium duty. Match RD2060R to a radius corner mortise like the 1/4 inch radius prep the Orca 4014 uses, and 2060R to a square corner mortise.

Toilet partition doors are usually hung on spring loaded continuous hinges rather than 4 by 4 inch butt spring hinges like the Orca 4014. The Pemko Markar FM900 series is a spring loaded continuous hinge with 80 lb capacity for toilet partitions, and the Pemko Markar FS902 series is a spring loaded continuous hinge for toilet partitions in 304 stainless steel with 80 lb capacity. The stainless FS902 is the one to specify where the stall is exposed to moisture and cleaning chemicals.

They solve the same self-closing problem in different hardware. The Orca 4014 is a 4 by 4 inch mortise spring hinge that installs in individual leaf mortises. The Pemko Markar FM400 series is a full mortise spring loaded continuous hinge with 80 lb load capacity for toilet partitions, and the Pemko FS402 series is a spring loaded continuous hinge for toilet partitions, also 80 lb. A continuous hinge runs the height of the door edge, so swapping to one means preparing the full edge rather than three or four discrete mortises.

The Hager 1150 is a full mortise spring hinge in standard weight stainless steel at medium duty. The Orca 4014 spring hinge is steel. Where the opening sees exterior exposure or frequent washdown, the stainless 1150 is the material to specify at the same medium duty level.
