Deltana DSH35R5 Single Action Spring Hinge, 3-1/2" x 3-1/2" x 5/8" Radius, Steel

That's what they're for. The DSH35R5 is a self-closing spring hinge, so the spring is inside the hinge barrel and there's no overhead closer on the frame. Closing force is adjustable at the hinge, so you can tension it to the weight of the door and how hard it needs to pull the latch. It's a single action hinge, meaning the door swings one direction only, not both ways like a cafe door hinge.

No, the DSH35R5 is not an NRP hinge. On an outswing door where the hinge barrel is on the exterior side, that leaves the pin reachable from outside. Security integrators and property managers on exterior outswing openings usually specify a non-removable pin or a security stud hinge instead. For interior openings, or any door that swings in, the standard pin is not an issue.

The DSH35R5 is only made at 3-1/2 by 3-1/2 inches, so it won't fill a 4 inch mortise. Orca Hardware makes a 4 by 4 spring hinge with the same 5/8 inch radius corner (SPR4058), which is the direct size step up with matching corner geometry. Orca also does a 4 by 4 square corner version (SPR4040) and a 4 by 4 with 1/4 inch radius (SPR4014) if your existing mortise is cut differently. For 4-1/2 inch openings, the McKinney 1502 is a square corner full mortise spring hinge at 4-1/2 by 4-1/2.

For an opening that needs a listed self-closing hinge, the Emtek 95013 is a UL listed spring hinge in 3-1/2" x 3-1/2" with square corners, and the Design Hardware UL Spring Hinge is a medium duty UL spring hinge. Among concealed options, the SOSS 216IC and SOSS 220IC invisible spring closer hinges carry a 20 minute fire rating in heavy duty. The Deltana DSH35R5 is a steel single action spring hinge specified for commercial use.

The Deltana DSH35R5 is a 3-1/2" x 3-1/2" steel spring hinge with 5/8" radius corners. The closest match by corner profile is the Hager 1252 full mortise spring hinge, which also carries 5/8" round corners in standard weight steel. If the opening takes a 4" leaf instead, the Orca Hardware SPR4058 is a 4" x 4" spring hinge with the same 5/8" radius corner. Match the corner radius to the existing mortise: a 5/8" radius hinge will not drop into a pocket routed for square corners without rework.

The Deltana DSH35R5 has 5/8" radius corners, so it suits a radiused mortise. For a square corner prep, the Emtek 95013 is a 3-1/2" x 3-1/2" square corner spring hinge in plated steel, sold as a pair and UL listed. In larger leaf sizes, the Orca Hardware SPR4040 is a 4" x 4" square corner spring hinge and the McKinney 1502 is a 4-1/2" by 4-1/2" square corner full mortise spring hinge in standard weight. The BEST 2060R is a square corner standard weight spring hinge with a removable pin.

The Deltana DSH35R5 is a conventional mortise spring hinge with visible knuckles at the door edge, offered in finishes including oil rubbed bronze, polished nickel and polished chrome so it reads as part of the trim. If the design calls for no visible hardware, the SOSS invisible spring closer hinges conceal entirely in the door and frame: the 216IC series and the 220IC series are heavy duty with a 20 minute fire rating, and the 218IC is a 7" heavy duty unit. Door thickness governs the choice, since the 218IC requires a 1-3/4" minimum door thickness and the 220IC requires 2".

Screws come with it, in both patterns. Wood screws are #9 x 3/4 for a wood jamb or wood door, and machine screws are #9 x 1/2 for a hollow metal frame that's already drilled and tapped. So a wood door in a wood frame needs nothing else; a hollow metal frame needs the tap to already be there, since the hinge doesn't come with anchors or clips.

Deltana rates the DSH35R5 for commercial use. It's steel, with a leaf thickness of 0.097 inch, running on a plain bearing rather than ball bearings. Plain bearing is the standard construction for medium duty openings; on very high traffic or heavy doors, a ball bearing hinge is the usual step up. The steel body also means finish is a plated or painted coating, so exterior or wet locations wear it faster than a stainless leaf would.

A spring hinge hides the closing mechanism inside the hinge, so nothing hangs off the top of the door. That's why it wins on apartment unit doors, stairwell doors, and any opening where an overhead arm looks wrong or gets vandalized, and it's why the DSH35R5 is offered in eleven decorative finishes rather than just painted steel. What you give up is controlled closing: a spring hinge pulls the door shut, but it doesn't give you the sweep speed, latch speed, backcheck, and hold open adjustments a closer does. Heavy doors, high traffic, and ADA opening force requirements are closer territory.

Yes. The DSH35R5 mortises into the door and jamb edge the normal way, so the barrel and knuckles show when the door is closed. If you want nothing visible at all, the SOSS invisible spring closer hinges do the same self closing job fully concealed in the door edge: the 218IC is a 7 inch heavy duty unit needing a 1-3/4 inch minimum door thickness, and the 220IC is 7 inch with a 2 inch minimum door thickness. Both are heavy duty, and both need a routed pocket in the door edge rather than a standard hinge mortise.

The BEST RD2060R is the closest peer on that point, a plain bearing spring hinge with a radius corner and a removable pin, rated medium duty. BEST also lists the 2060R in a square corner with a removable pin. For steel full mortise radius corner spring hinges from Hager, the 1252 has 5/8 inch round corners and the 1251 has 1/4 inch round corners, both standard weight steel; the Hager 1150 is the stainless steel version if the opening is exterior or washdown.

No handing to specify. The DSH35R5 is ordered by size, corner radius, and finish only, so the same hinge works on a left hand or right hand door. Closing direction comes from how you tension the spring during install, not from a factory hand. That also means one part number covers a whole building of mixed swings, which is what a property manager stocking spares wants.

They are not interchangeable. The Deltana DSH35R5 is a single action full leaf spring hinge, 3-1/2" x 3-1/2" in steel, mortised into discrete pockets and sold in a pair for one door. The Pemko Markar FM400 and FM900 series and the Pemko FS402 and FS902 series are spring loaded continuous hinges built for toilet partitions with an 80 lb load capacity; the FS902 is 304 stainless steel. A continuous hinge runs the height of the door edge and needs the partition or door prepped for that, so it is not a drop in for a butt hinge mortise.

The Deltana DSH35R5 is steel. Where the substrate needs to be stainless, the Hager 1150 is a full mortise spring hinge in standard weight stainless steel, medium duty. The Hager 1250 is the same full mortise standard weight spring hinge in steel construction if steel is acceptable. On a continuous hinge opening, the Pemko FS902 is 304 stainless steel.

The Orca Hardware SPR4058Z is a 4" x 4" x 5/8" radius corner spring hinge with a Z hole pattern. Its standard hole pattern counterpart is the Orca SPR4058, same 4" x 4" leaf and 5/8" radius corner. The Deltana DSH35R5 shares that 5/8" radius corner profile in a 3-1/2" x 3-1/2" leaf, so if the frame prep is a Z pattern the Orca SPR4058Z is the one to line up against the existing holes.

Eleven finishes, which is what usually decides this hinge over a plain painted commercial one: Polished Brass, Brushed Brass, Antique Brass, US3/4, Polished Nickel, Brushed Nickel, Antique Nickel, Polished Chrome, Brushed Chrome, Oil Rubbed Bronze, and Paint Black. For a property manager matching existing openings, that range covers most decorative lever and knob finishes, so the spring hinge doesn't have to look like an afterthought next to the trim.
