Deltana DSH4R5BM Single Action Spring Hinge Benchmark, 4" x 4" x 5/8" Radius Corner, Steel, UL Listed

It fits a 4 x 4 inch mortise cut with 5/8 inch radius corners. That's the common commercial radius, but it is not the only one, so check what's already routed in the door and frame. If your existing pockets are square-cornered or cut to a 1/4 inch radius, this one leaves a visible gap at the corners and you want a square corner or 1/4 radius hinge instead.

The DSH4R5BM is UL Listed and it is a self-closing spring hinge, which is the reason most people put it on a labeled opening in the first place. Whether the whole assembly stays compliant depends on the door and frame label and how many hinges the label calls for, so match it to the door's listing before you install.

It's a self-closing hinge, so it pulls the door shut without a surface closer, and the spring tension is adjustable so you can dial in how hard it pulls. What it does not do is control the speed of the swing, so on a heavy or high-traffic entrance where you need latching control and a soft close, a closer is still the right tool. On stairwell doors, apartment entry doors, and interior openings that just need to shut behind people, the spring hinge on its own is the usual answer.

No, the DSH4R5BM does not have an NRP feature. On an outswing exterior door where the barrel is exposed on the outside, that matters, and you want a hinge with a non-removable pin or a security stud instead. On an inswing door or any interior opening it isn't an issue.

The DSH4R5BM uses the Benchmark hole pattern, which is a specific screw hole layout rather than a universal one. Coming off another brand's hinge, the holes will not necessarily land on your existing pilot holes, so on a retrofit expect to drill fresh. Spring hinges are also sold in other patterns, for example the Orca Hardware SPR4058Z, which is the same 4 x 4 with 5/8 inch radius corners but in a Z hole pattern.

Go to a square corner spring hinge so the leaf matches the existing prep. The Orca Hardware SPR4040 is a 4 inch by 4 inch square corner spring hinge, medium duty, in the same size class. The BEST 2060R is also a square corner spring hinge, plain bearing, standard weight and medium duty, and it uses a removable pin. The Deltana DSH4R5BM is cut with 5/8 inch radius corners, which will leave a gap at the corners of a square mortise.

They are not the same category of prep. The Deltana DSH4R5BM is a full-leaf butt-style spring hinge, 4 inch by 4 inch, that mounts in a surface mortise on the door edge and frame. The SOSS 216IC, 218IC and 220IC are invisible spring closer hinges that require a routed pocket in the door edge and jamb and disappear when the door is closed; all three are heavy duty, the 216IC and 220IC carry a 20 minute fire rating, the 218IC is a 7 inch hinge needing 1-3/4 inch minimum door thickness and the 220IC is 7 inch needing 2 inch minimum door thickness. Swapping in either direction means recutting the door.

The Orca Hardware SPR4058 is the nearest match in geometry: it is a 4 inch by 4 inch spring hinge with 5/8 inch radius corners, the same size and corner style the DSH4R5BM carries. Orca rates the SPR4058 medium duty. If the door already has 5/8 inch radius corner mortises cut, either part drops into that prep without recutting.

The radius refers to how the leaf corners are rounded, and it has to match the corner the router or template cut in the door and frame. The Deltana DSH4R5BM carries 5/8 inch radius corners. The Orca Hardware SPR4014 is a 4 inch by 4 inch spring hinge with 1/4 inch radius corners, and Hager offers both radii in its steel spring hinge line: the 1251 with 1/4 inch round corners and the 1252 with 5/8 inch round corners, both full mortise standard weight steel. Confirm which radius is in the opening before ordering, because the two are not interchangeable in an existing mortise.

The Hager 1150 is a full mortise spring hinge in stainless steel, standard weight and medium duty. The Deltana DSH4R5BM is a steel hinge, and the Hager 1250 is the steel construction counterpart to the 1150 in the same standard weight full mortise line. On exterior openings, pool and coastal doors, and washdown areas, buyers usually specify the stainless body.

Single action. It swings one way, like a normal butt hinge, and springs the door back to closed. If you need a door that pushes open from both sides and returns to center, such as a kitchen or service pass-through, a single action hinge won't do it and you need a double action model.

Four: Brushed Nickel, Brushed Brass, Zinc Dichromate, and Prime Coat White. Zinc dichromate is the plain utility finish for openings nobody looks at, and prime coat white is meant to be painted to match the door or trim, which is what most property managers use on apartment corridor doors. Brushed nickel and brushed brass are the ones to pick when the hinge is visible alongside the rest of the door hardware.

Commercial. It's steel, 0.097 inch gauge, with plain bearings, which is standard weight commercial construction rather than a light residential hinge. Plain bearing is the right choice for medium duty openings; on a very heavy door or an entrance cycling constantly all day, ball bearing hinges with a separate closer hold up better.

Partition doors are usually served by a spring loaded continuous hinge rather than a pair of butts. The Pemko Markar FM400 and FM900 series are full mortise style spring loaded continuous hinges rated to an 80 lb load for toilet partitions, and the Pemko FS402 and FS902 series cover the same 80 lb partition application, with the FS902 in 304 stainless steel. The Deltana DSH4R5BM is a 4 inch by 4 inch commercial butt spring hinge for a standard mortised door opening.

The Orca Hardware SPR4058Z is the same 4 inch by 4 inch 5/8 inch radius corner spring hinge geometry but drilled in the Z hole pattern, while the Orca SPR4058 is the standard hole pattern in that size. The Deltana DSH4R5BM is drilled Benchmark and takes #10 x 1 inch wood screws and #10 x 1/2 inch machine screws. Match the hole pattern to the existing frame prep so the screw holes land in fresh material.

For a heavy duty self-closing hinge the SOSS 216IC, 218IC and 220IC invisible spring closers are all rated heavy duty, with the 218IC and 220IC in the 7 inch size. Among the mortise butt spring hinges, the Hager 1250, McKinney 1502, Orca SPR4058 and BEST RD2060R are all medium duty standard weight. The Deltana DSH4R5BM is a commercial steel spring hinge at 0.097 thickness with plain bearings.

No handing to specify. The DSH4R5BM is ordered by size, corner radius, hole pattern, and finish, and the same hinge works on a left hand or right hand door. The only choices you make are the 4 x 4 size with 5/8 inch radius corners and which of the four finishes you want.

Yes, and that's normal practice. A common setup is one or two spring hinges plus a standard butt hinge on the same leaf, with the springs providing the close. What has to match for it to look right is the size, the corner radius, and the finish, so pair the 4 x 4 with 5/8 inch radius corners against hinges cut to the same mortise. Steel construction at 0.097 thickness keeps it in line with standard weight commercial butts.
