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

That's what they're for. The DSH35R4 is a self-closing spring hinge with adjustable spring tension, so the closing force is built into the hinge barrel instead of hanging off a surface closer. You set the tension at install and adjust it later if the door isn't latching or is slamming. Note the unit of measure: these are sold each, not by the pair, so a door that needs two spring hinges takes two units.

It depends which radius you have. The DSH35R4 is cut with 1/4 inch radius corners, which is the common radius on residential and light commercial prehung jambs. If your existing mortise is square-cornered or a 5/8 inch radius, the leaf won't seat cleanly. For 5/8 inch radius openings, Hager's 1252 is a full mortise spring hinge with 5/8 inch round corners; for square corners, look at the Hager 1250 or Emtek 95013.

The Deltana DSH35R4 is built at 3-1/2 inch by 3-1/2 inch and will leave gaps in a 4 inch mortise. For 4 inch prep 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, medium duty. If the frame uses a 5/8 inch radius instead, the Orca SPR4058 is the 4 inch by 4 inch 5/8 inch radius version. For a 4-1/2 inch by 4-1/2 inch opening, the McKinney 1502 is a square corner full mortise standard weight spring hinge at that size.

If the opening requires a listed self-closing hinge, the Design Hardware UL Spring Hinge is a medium duty UL spring hinge, and the Emtek 95013 is a UL listed 3-1/2 inch by 3-1/2 inch plated steel spring hinge pair with square corners. For a rated concealed application, the SOSS 216IC invisible spring closer hinge carries a 20 minute fire rating in heavy duty, as does the SOSS 220IC in a 7 inch size for doors 2 inch minimum thickness. The Deltana DSH35R4 is a steel single action spring hinge intended for commercial openings.

The Deltana DSH35R4 is a 3-1/2 inch by 3-1/2 inch steel spring hinge with 1/4 inch radius corners and a plain bearing. The closest match by corner profile is the BEST RD2060R, a medium duty plain bearing spring hinge with a removable pin and radius corners. The Hager 1251 is a full mortise spring hinge with 1/4 inch round corners in standard weight steel, which matches both the corner radius and the steel construction. Confirm the leaf size you need before ordering either, since corner profile and material are what these share with the DSH35R4.

The Deltana DSH35R4 is a surface visible full mortise spring hinge with steel leaves in finishes such as oil rubbed bronze, polished nickel and polished brass. If the door needs to close itself with no visible hinge, the SOSS invisible spring closer hinges conceal in the door and frame edge: the 216IC is a heavy duty invisible spring closer with a 20 minute fire rating, the 218IC is a 7 inch heavy duty unit requiring a 1-3/4 inch minimum door thickness, and the 220IC is a 7 inch unit for a 2 inch minimum door thickness. Check your door thickness before specifying a SOSS, since the concealed body sets the minimum.

Both screw types ship with it: #9 x 3/4 wood screws for the door and timber jamb, and #9 x 1/2 machine screws for a drilled and tapped hollow metal frame. That machine screw is the one that matters on a steel frame, and it's included, so there's nothing extra to order for a standard mortise install.

No handing to specify. The DSH35R4 is a single action spring hinge, symmetrical in the mortise, so the same part hangs a left hand or right hand door. The only thing you pick on the order is the finish.

The DSH35R4 is not a non-removable-pin hinge. On an out-swinging exterior or entry door where the barrel is exposed, that's worth thinking about, since NRP or a security stud is what keeps the leaf from being lifted off. Inside the building, on a stairwell, corridor, or apartment interior door, it's a non-issue. The BEST 2060R and RD2060R spring hinges are also removable pin, so if pin security is the driver you want an NRP hinge rather than any of these.

Deltana rates the DSH35R4 for commercial use. It's steel through the leaf and pin, 0.097 inch thick, on a plain bearing, which is standard weight construction rather than heavy duty. For a light-traffic commercial opening, an office door, a closet, a corridor door, that's the right class of hinge. For a high-cycle or heavy leaf, the SOSS 218IC and 220IC invisible spring closers are heavy duty rated.

A spring hinge like the DSH35R4 hides the closing mechanism in the mortise, so nothing shows on the face of the door and there's no arm to catch. What it doesn't give you is controlled sweep and latch speed, which is why it suits interior doors, closets, and light corridor doors rather than an entrance you need to close slowly. If you want the mechanism completely invisible with the door shut, SOSS invisible spring closer hinges are the concealed alternative; the 218IC needs a 1-3/4 inch minimum door thickness and the 220IC needs 2 inches.

No. The Deltana DSH35R4 is a 3-1/2 inch by 3-1/2 inch full leaf spring hinge installed in individual mortises. The Pemko Markar FM400 and FM900 series are spring loaded continuous hinges rated to an 80 lb load capacity for toilet partitions, and the Pemko FS402 and FS902 series are the same style of spring loaded continuous hinge for partitions, with the FS902 in 304 stainless steel. Those run the height of the partition door and need a continuous hinge prep, so they are the answer for a stall door, not a drop-in for a 3-1/2 inch mortise.

The Deltana DSH35R4 is built in steel. Where the opening calls for 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 design in steel construction if steel is acceptable, and the Pemko Markar FS902 continuous spring loaded hinge is 304 stainless for partition work. Stainless is the usual pick for exterior, coastal, or wash down areas.

The Deltana DSH35R4 is not a non-removable pin hinge. If you specifically want a documented removable pin so the door can be lifted off without unscrewing the leaves, the BEST 2060R is a plain bearing spring hinge with removable pin in square corners standard weight, and the BEST RD2060R is the same removable pin plain bearing spring hinge in a radius corner, both medium duty. The radius corner RD2060R is the one that follows the same corner style family as the DSH35R4.

The Deltana DSH35R4 is a plain bearing steel spring hinge for commercial openings. Most of the full mortise spring hinge alternatives sit at medium duty, including the Hager 1250 and 1251 in standard weight steel and the McKinney 1502 in 4-1/2 inch by 4-1/2 inch. The SOSS invisible spring closer hinges are the heavy duty option: the 216IC and the 218IC are both heavy duty, with the 218IC at 7 inch and a 1-3/4 inch minimum door thickness. Those install concealed in the door edge, so plan the routing rather than a standard mortise.

Eleven finishes: oil rubbed bronze, polished nickel, brushed nickel, antique nickel, paint black, polished chrome, brushed chrome, polished brass, brushed brass, antique brass, and US3/4. That covers the usual matches to lever and knob trim across a building, so a property manager standardizing a floor can hold one finish across every opening.

Both are 1/4 inch radius corner spring hinges in steel, so the corner prep and material line up: the Deltana DSH35R4 is a steel spring hinge with 1/4 inch radius corners, and the Hager 1251 is a full mortise spring hinge with 1/4 inch round corners in standard weight steel construction. The difference to check is leaf size, since the DSH35R4 is 3-1/2 inch by 3-1/2 inch, and finish, since the DSH35R4 runs finishes like brushed nickel, antique brass and polished chrome. For a fleet of doors where appearance matters, keeping all hinges on one opening from the same model is the cleaner result.
