Deltana DSH4R5 Single Action Spring Hinge 4" x 4" x 5/8" Radius Corner, Steel, UL Listed

Yes. The DSH4R5 is a 4 x 4 inch full mortise spring hinge with 5/8 inch radius corners, which is the corner profile used on most hollow metal frames and factory-prepped metal doors. If your existing hinge pockets are square-cornered (wood doors, older frames), the radius leaf will leave a gap at the corners and you want a square corner spring hinge instead, such as the Orca Hardware 4040 Series 4 x 4 square corner. For a tighter 1/4 inch radius prep, the Orca 4014 Series matches that profile.

The DSH4R5 is UL Listed, which is what lets a self-closing spring hinge be used on a rated opening in place of a surface closer. It is rated commercial, not residential-only. Two things to know before you commit: UL Listed hinges are used in sets (typically all hinges on the leaf, with the spring hinges providing the closing force), and the listing on the door assembly itself governs how many self-closing hinges that particular door requires. The DSH4R5 is a single action hinge, so it closes a door swinging one direction only.

No. The DSH4R5 is not an NRP hinge, so on an out-swinging exterior door the pin side is exposed and you would want either a hinge with a non-removable pin or a set of security studs. For interior corridor, stairwell, and apartment doors where the barrel is on the secure side, it is not an issue.

They are different animals. The DSH4R5 is a full mortise butt hinge in a 4 inch by 4 inch size, installed as a pair or set in individual mortises. 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 in 304 stainless steel. A continuous hinge runs the full leaf height and needs continuous prep, so it does not substitute into 4 by 4 hinge pockets on a swinging door.

The DSH4R5 has 5/8 inch radius corners and will not sit correctly in a square corner mortise. For square prep at the same 4 inch by 4 inch size, use the Orca Hardware SPR4040, a 4 by 4 square corner spring hinge in medium duty. Other square corner options are the BEST 2060R plain bearing spring hinge with removable pin in standard weight, and the McKinney 1502 square corner full mortise spring hinge, which is 4-1/2 inch by 4-1/2 inch and needs a mortise cut to that larger size.

No. Corner radius has to match the mortise. The DSH4R5 is cut with 5/8 inch radius corners, so for a 1/4 inch radius pocket at 4 inch by 4 inch use the Orca Hardware SPR4014, a 4 by 4 by 1/4 inch radius corner spring hinge in medium duty. Hager also splits its full mortise spring hinges by corner: the 1251 has 1/4 inch round corners and the 1252 has 5/8 inch round corners, both standard weight steel. Measure the radius on the hinge coming out of the door before ordering.

The DSH4R5 is steel. Where a stainless base metal is specified, such as a washdown area, pool room, or coastal exterior, the Hager 1150 full mortise spring hinge is standard weight stainless steel in medium duty. The Hager 1250 is the steel construction counterpart in the same standard weight full mortise pattern if stainless is not required.

The DSH4R5 is a 4 inch by 4 inch hinge and will overhang a 3-1/2 inch prep. For the smaller size, the Emtek 95013 is a 3-1/2 inch by 3-1/2 inch UL listed spring hinge pair in plated steel with square corners. Note the corner difference: the Emtek is square corner while the DSH4R5 is 5/8 inch radius, so match the corner to the existing mortise as well as the size.

Priced and sold each, not by the pair. The Deltana spring hinge data lists the unit of measure as each, so a standard 3-hinge commercial door needs three units ordered, and if you are mixing (common practice is spring hinges at top and bottom with a standard butt in the middle) count only the spring hinges you actually need. Order the same finish across the leaf so the exposed knuckles match.

Both are supplied. The DSH4R5 ships with #10 x 1 inch wood screws for wood doors and jambs, plus #10 x 1/2 inch machine screws for hollow metal doors and frames that are tapped for hinge attachment. Nothing else is needed to hang it, though a hex wrench or tension pin tool is used to adjust the spring tension after mounting.

Yes, the spring tension on the DSH4R5 is adjustable, so you can dial the closing force up on a door that is not latching or back off on one that slams. That matters on multifamily and light commercial openings where the same hinge has to handle doors of different weights, and it is the practical advantage of a spring hinge over a fixed-tension butt.

Leaf thickness is 0.097 inches in steel, which is standard weight rather than heavy weight. That suits interior commercial and multifamily doors of typical weight and traffic. For a heavy or high-abuse opening, or where you cannot give up hinge appearance at all, the SOSS 218IC invisible spring closer hinge is a heavy duty alternative, and it requires a minimum door thickness of 1-3/4 inches.

Thirteen finishes on the DSH4R5, which is wider than most spring hinges offer: Oil Rubbed Bronze, Polished Nickel, Brushed Nickel, Antique Nickel, Polished Chrome, Brushed Chrome, Polished Brass, Brushed Brass, Antique Brass, US3/4, Paint Black, Zinc Dichromate, and Prime Coat White. Zinc Dichromate and Prime Coat White are the utility options for concealed or paint-to-match work; Prime Coat White takes finish paint so you can match a painted frame exactly. The decorative finishes matter when the hinge is on a visible residential-style opening in a commercial building and has to match the lever and the strike.

Both self-close a door without a surface closer, but they mount differently. The DSH4R5 is a full mortise spring hinge with 5/8 inch radius corner leaves that sit in a standard hinge prep and stay visible on the edge of the door. The SOSS 216IC is an invisible spring closer that conceals entirely when the door is shut, is heavy duty, and carries a 20 minute fire rating. Choose the Deltana when you are working with existing hinge preps and want a straightforward swap; choose the invisible unit when the door edge has to look clean and you can machine the pocket for it.

Spring hinges of this type are not handed the way a lockset is; the DSH4R5 is a single action hinge, meaning it closes a door that swings one direction, and it is installed with the spring oriented to close that swing. Order the same part regardless of whether the opening is left or right hand. What you do need to fix at install is the tension, which is adjustable on the hinge after mounting.

The DSH4R5 leaf is steel, so for a coastal, wet, or washdown opening look at the Hager 1150 full mortise spring hinge, which is standard weight stainless steel. The steel-bodied Hager 1250 is the direct construction equivalent to the Deltana, and the Hager 1252 is the version with 5/8 inch round corners, matching the same corner prep the DSH4R5 uses.

Three things decide whether a spring hinge swaps cleanly across a fleet of doors: leaf size, corner radius, and finish. The DSH4R5 covers 4 x 4 inch openings with a 5/8 inch radius corner prep in steel, and it comes in thirteen finishes so you can match whatever is already on the doors. Walk a sample of openings and confirm the existing hinge is 4 x 4 with radius corners, not square. If some doors are square cornered, the Orca 4040 Series is the 4 x 4 square corner spring hinge that keeps the rest of the spec consistent.

The DSH4R5 is a 4 inch by 4 inch plain bearing spring hinge for commercial use. Where a heavy duty self-closer is specified, the SOSS invisible spring closer hinges step up: the 216IC carries a 20 minute fire rating in heavy duty, the 218IC is a 7 inch heavy duty unit calling for a 1-3/4 inch minimum door thickness, and the 220IC is a 7 inch heavy duty with a 20 minute fire rating and a 2 inch minimum door thickness. These mount concealed in the door and frame edge rather than in a butt hinge mortise, so the prep is not interchangeable with a 4 by 4 pocket.

Both are 4 inch by 4 inch spring hinges with 5/8 inch radius corners in medium duty, the same size and corner style as the Deltana DSH4R5. The SPR4058Z is built with a Z hole pattern, so the screw holes fall in a different arrangement on the leaf. If you are replacing hinges into existing screw holes rather than a fresh mortise, the hole pattern is the detail that decides which one lands on the existing fasteners.

The DSH4R5 comes in thirteen finishes including Oil Rubbed Bronze, Polished Nickel, and Prime Coat White, which matters when the hinge has to match visible trim. On a back-of-house opening where appearance is not driving the choice, the Design Hardware UL Spring Hinge is a medium duty UL spring hinge, and the Hager 1250 is a standard weight steel construction full mortise spring hinge. Confirm size and corner style against the existing mortise before ordering either.

The DSH4R5 uses a plain bearing knuckle. Plain bearing is the norm on spring hinges and is fine for standard weight doors at moderate traffic; ball bearing construction is what you specify for heavy doors or very high cycle openings where knuckle wear becomes the issue. Among comparable spring hinges, the BEST RD2060R is also a plain bearing radius corner unit, so it is the same construction class.
