Deltana DSH4R5T Single Action Spring Hinge, 4" x 4" x 5/8" Radius Corner, Steel, TT, UL Listed

Yes. The DSH4R5T is a 4 x 4 inch spring hinge with 5/8 inch radius corners, which is the standard corner profile on most hollow metal frames and prepped metal doors. The corner style is listed as 5/8 inch radius by square corners, so it also works where one leaf sits in a square-corner wood door prep. Match the 5/8 inch radius leaf to the frame side and you are in the existing mortise with no filing.

The DSH4R5T carries a UL Listed certification, and it is a self-closing spring hinge, which is the function a fire door needs to latch on its own. It is a steel hinge rated by Deltana for commercial use. Confirm the door and frame assembly's own label covers self-closing spring hinges as the closing device for your rating.

Pricing on the DSH4R5T is per unit, each. The unit of measure is stated as each, so if you need two spring hinges on an opening you order two. Common practice on a standard 3-hinge door is two spring hinges plus one plain bearing hinge, so count what the opening actually calls for before you set quantity.

Both sets ship with the hinge. The DSH4R5T includes #10 x 1 wood screws for the door or wood jamb side and #10 x 1/2 machine screws for a metal frame with tapped holes, so one part covers a wood door hung in a hollow metal frame without a separate fastener order.

Spring hinges like the DSH4R5T close the door from the hinge itself, so there is no arm or body on the face of the door and nothing to prep for on the header. That suits apartment entry doors, stairwell doors, and anywhere the look matters or the header has no room. A surface closer gives you controlled sweep and latch speed, backcheck, and hold-open, which spring hinges do not offer. If the opening needs speed control or hold-open, use a closer; if it just needs to shut and latch on its own, spring hinges do it with no extra hardware on the door.

The Orca Hardware SPR4058 is the direct match: a 4 x 4 inch spring hinge with 5/8 inch radius corners, same size and corner profile as the DSH4R5T, so it goes into the same mortise. Orca also lists a 5/8 inch radius version with a Z hole pattern, SPR4058Z, if your existing prep uses staggered holes. If the frame is a square-corner prep instead, the Orca SPR4040 is 4 x 4 with square corners, and if it is a 1/4 inch radius prep, the SPR4014 covers that.

The DSH4R5T is cut with 5/8 inch radius corners, which will not sit correctly in a square corner pocket. For a square prep in the same 4 inch by 4 inch size, the Orca Hardware SPR4040 is a 4 inch by 4 inch square corner spring hinge. The BEST 2060R is a square corner plain bearing spring hinge in standard weight, and the McKinney 1502 is a square corner full mortise spring hinge in standard weight at 4-1/2 inch by 4-1/2 inch, so confirm your pocket size before ordering that one. Measure the existing hinge corner before you order either way, since a radius hinge in a square pocket leaves a visible gap at each corner.

The Orca Hardware SPR4058 spring hinge matches the same 4 inch by 4 inch size with a 5/8 inch radius corner that the DSH4R5T carries, so it drops into the same mortise prep without recutting the door or frame. The Orca SPR4058 is rated medium duty. The Hager 1252 is another 5/8 inch round corner full mortise spring hinge in standard weight steel construction, which is the same steel material the DSH4R5T uses. If the corner radius is what has to match, those two are where to look first.

No. The DSH4R5T is a 5/8 inch radius corner hinge, and a 1/4 inch pocket is a tighter curve, so the leaf will not seat. The Orca Hardware SPR4014 is a 4 inch by 4 inch spring hinge cut with a 1/4 inch radius corner, and the Hager 1251 is a full mortise spring hinge with 1/4 inch round corners in standard weight steel construction. Both hold the same self-closing spring function in the smaller radius.

Yes, the spring tension is adjustable. Deltana's self-closing spring hinges are built to be tensioned in the field, which is how you get the door to latch reliably without slamming. On a multi-hinge opening, tension the spring hinges evenly rather than loading all the closing force onto one.

Leaf thickness is 0.097 inches in steel, and Deltana rates the DSH4R5T for commercial use. That is a standard-weight gauge, so it suits normal-traffic commercial and multi-family openings on standard doors. For a heavy or high-abuse door leaf, step up rather than relying on spring hinges alone to control it.

The DSH4R5T is not a non-removable-pin hinge. On an outswing door where the barrel is exposed to the outside, that leaves the pin reachable, so pair it with a set screw, a hinge pin stud, or a security stud plate on the opening. On inswing doors, where the barrel sits on the secure side, it is a non-issue.

Nine finishes: oil rubbed bronze, antique nickel, brushed nickel, brushed chrome, polished chrome, polished brass, brushed brass, antique brass, and zinc dichromate. That covers a decorative match to lever and lockset finishes across a building, and the zinc dichromate option is the utility choice where the hinge is behind a door bottom or in a back-of-house opening and appearance does not matter.

No. The DSH4R5T is a single action spring hinge, meaning the door swings one direction only and the spring returns it to the closed position. For a door that has to swing both ways, you need a double action spring hinge, which is a different part.

For standard 4 x 4 hinge preps, yes. The DSH4R5T is a commercial-rated, UL Listed steel spring hinge in nine finishes, so one model covers unit entry doors, corridor doors, and back-of-house openings with the finish varied to suit each. The limits to check before you commit a whole fleet: every opening needs a 4 x 4 prep, and openings that need hold-open or speed control need a closer instead.

The DSH4R5T is steel. Where you need stainless for a coastal, wet, or wash-down opening, the Hager 1150 is a full mortise standard weight spring hinge in stainless steel. The Hager 1250 is the steel-construction equivalent, and the 1252 is that same steel hinge with 5/8 inch round corners if you are matching a radius prep.

The DSH4R5T is 4 x 4 and will not fit a 3-1/2 inch prep. The Emtek 95013 is a 3-1/2 x 3-1/2 inch spring hinge pair with square corners in plated steel and is UL Listed, which is the common size on residential and light interior door preps.

The DSH4R5T is not a non-removable pin hinge. If a removable pin is what the job calls for, the BEST 2060R is a plain bearing spring hinge with a removable pin in square corners standard weight, and the BEST RD2060R is the radius corner version, also plain bearing standard weight with a removable pin. The DSH4R5T is a plain bearing hinge as well, so the bearing behavior is the same across all three; the RD2060R is the one to look at if you need to hold the radius corner prep.

They solve self-closing in two different ways. The DSH4R5T is a full-size 4 inch by 4 inch butt-style spring hinge in steel that mortises into a standard hinge pocket and remains visible on the edge of the door. The SOSS 216IC and 220IC are invisible spring closer hinges with a 20 minute fire rating, and the SOSS 218IC is a 7 inch invisible spring closer requiring a 1-3/4 inch minimum door thickness, with the 220IC calling for 2 inch minimum thickness. All three SOSS units are heavy duty. The SOSS hinges need a routed pocket in both the door edge and the jamb rather than a standard hinge mortise, so they are not a swap for the Deltana on an existing prep.

Not on a standard door opening. The Pemko Markar FM400 and FM900 series and the Pemko FS402 and FS902 series are spring loaded continuous hinges built for toilet partitions, each with an 80 lb load capacity, and the FS902 is 304 stainless steel. A continuous hinge runs the full height of the panel edge rather than dropping into individual 4 inch by 4 inch mortises the way the DSH4R5T does. If the job is a restroom partition door, the Pemko units are the right family; if it is a hinged door with existing butt hinge pockets, stay with a butt-style spring hinge.

The DSH4R5T is a steel hinge offered in finishes including polished chrome, brushed chrome and zinc dichromate. Where the substrate itself needs to be stainless, the Hager 1150 is a full mortise spring hinge in standard weight stainless steel, rated medium duty. The Hager 1250 is the same full mortise standard weight spring hinge in steel construction if stainless is not required. Both are full mortise like the Deltana, so the prep style carries over.

Two families cover all three corner preps. Orca Hardware runs the SPR4040 in 4 inch by 4 inch square corner, the SPR4014 in 4 inch by 4 inch with 1/4 inch radius corner, and the SPR4058 in 4 inch by 4 inch with 5/8 inch radius corner, all medium duty. Hager covers the same ground with the 1250 in standard weight steel construction, the 1251 with 1/4 inch round corners and the 1252 with 5/8 inch round corners, all full mortise medium duty. The Deltana DSH4R5T fills the 5/8 inch radius, 4 inch by 4 inch position in steel and is UL Listed for commercial use, so it can sit alongside either family where that corner is what the frames were cut for.

Plain bearing, which is standard on spring hinges of this class and appropriate for normal commercial traffic. Plain bearing hinges carry the load on the knuckle rather than a ball race, so on very high-frequency openings, a ball bearing hinge in the non-spring position of the door is the usual pairing to spread wear.

The DSH4R5T is a plain bearing steel spring hinge in a 4 inch by 4 inch leaf, listed for commercial use. Most of the butt-style spring hinges alongside it sit at medium duty, including the Orca SPR4058, the Hager 1252, the McKinney 1502 and the BEST RD2060R. The SOSS 216IC, 218IC and 220IC invisible spring closers are rated heavy duty, though they need a routed pocket in the door edge and jamb rather than a butt hinge mortise, and the 218IC requires a 1-3/4 inch minimum door thickness. On an opening already prepped for butt hinges, the medium duty butt-style options are the ones that install without rework.
