Deltana DSH35R4-A Single Action Spring Hinge, 3-1/2" x 3-1/2" x 1/4" Radius, Steel

The DSH35R4-A is not a non-removable pin hinge. On an outswing door where the barrel is on the exterior side, that leaves the pin accessible from outside, so for exterior outswing security openings you want an NRP hinge or a security stud. On interior doors and inswing doors it is a non-issue.

Do not assume it. Where a labeled opening requires a listed self-closing hinge, specify one that carries the listing outright, such as the Design Hardware UL Spring Hinge or the Emtek 95013, which is a UL Listed spring hinge. Match the hinge size and corner radius of your existing prep when you make the switch.

The Deltana DSH35R4-A has 1/4 inch radius corners and will not seat correctly in a square corner mortise. For square corner prep, the Emtek 95013 is a 3-1/2 inch by 3-1/2 inch square corner spring hinge in plated steel and is UL listed, which is the same leaf size as the DSH35R4-A. The BEST 2060R is a square corner plain bearing spring hinge in standard weight, and the Orca Hardware SPR4040 is a square corner spring hinge in a 4 inch by 4 inch size if the pocket is larger.

The Deltana DSH35R4-A is a steel single action spring hinge rated for commercial use. Where the submittal calls for a UL listed spring hinge, the Design Hardware UL Spring Hinge is built as a UL spring hinge in medium duty, and the Emtek 95013 is a UL listed 3-1/2 inch by 3-1/2 inch plated steel spring hinge that matches the DSH35R4-A leaf size. For a concealed application, the SOSS 216IC and 220IC invisible spring closer hinges carry a 20 minute fire rating.

The Deltana DSH35R4-A is a butt style spring hinge with 3-1/2 inch by 3-1/2 inch leaves that drops into conventional hinge prep. The Pemko Markar FM400 and FM900 and the Pemko FS402 and FS902 are spring loaded continuous hinges built for toilet partitions with an 80 pound load capacity, so they run the full height of the door edge rather than seating in individual pockets. The SOSS 216IC, 218IC and 220IC are invisible spring closer hinges that require a routed concealed pocket, with the 218IC needing a 1-3/4 inch minimum door thickness and the 220IC a 2 inch minimum. None of those retrofit into an existing 3-1/2 inch butt mortise.

No. The Deltana DSH35R4-A is cut with 1/4 inch radius corners, which will leave a gap in a 5/8 inch radius pocket. For 5/8 inch radius prep, the Hager 1252 is a full mortise spring hinge with 5/8 inch round corners in standard weight steel, and the Orca Hardware SPR4058 is a 4 inch by 4 inch 5/8 inch radius corner spring hinge. Orca also offers the SPR4058Z in the same 5/8 inch radius with a Z hole pattern if the frame screw layout calls for it.

The spring is built into the hinge barrel, so the hinge self-closes the door without a separate surface closer. That is the reason people specify a spring hinge on stair doors, apartment corridor doors and utility rooms where a closer body on the face of the door is unwanted. It gives you closing, not controlled latching speed the way a full closer does.

Deltana lists the DSH35R4-A as commercial. It is a steel hinge with a plain bearing barrel, which is the normal construction for standard weight, moderate traffic commercial openings rather than high frequency entry doors that call for ball bearing hinges.

The Deltana DSH35R4-A is single action, meaning the door swings one direction only and the spring returns it to the closed position against a stop. Choose a double action hinge only for a door that has to swing both ways, like a kitchen pass door. For any door in a rabbeted frame with a stop, single action is what you want.

Full mortise spring hinges of this type are non-handed. The spring tension is adjustable at the barrel after mounting, so the same DSH35R4-A pair works on a left hand or right hand opening. Just be sure the barrel ends up on the swing side of the door.

The Deltana DSH35R4-A is a 3-1/2 inch by 3-1/2 inch hinge. For a 4 inch by 4 inch leaf with the same 1/4 inch radius corner, the Orca Hardware SPR4014 is a 4 inch by 4 inch 1/4 inch radius corner spring hinge in the 4014 series. Orca also builds the SPR4058 in a 5/8 inch radius corner and the SPR4040 in a square corner at the same 4 inch size. In a larger leaf still, the McKinney 1502 is a 4-1/2 inch by 4-1/2 inch square corner full mortise spring hinge.

The Deltana DSH35R4-A is not supplied as a non-removable pin hinge. If you specifically want a spring hinge documented with a removable pin, the BEST RD2060R is a radius corner plain bearing standard weight spring hinge with a removable pin, and the BEST 2060R is the square corner version of the same plain bearing standard weight hinge with a removable pin. Both are medium duty.

The Deltana DSH35R4-A is a plain bearing steel spring hinge designated for commercial use. Among spring hinge alternatives, the Hager 1250 and 1251 and the Orca Hardware SPR4014 are standard weight medium duty hinges in the same class. For a heavy duty rating, the SOSS 216IC, 218IC and 220IC invisible spring closer hinges are classed heavy duty, though they mount concealed in a routed pocket rather than a butt mortise, so the door and frame have to be machined for them.

Oil Rubbed Bronze is the finish offered on the DSH35R4-A. If you are matching levers, pulls and strike plates across a building, that dark bronze tone will read against brass or satin chrome trim, so confirm the rest of the opening is in the same family before standardizing on it.
