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

It fits a standard 3-1/2 by 3-1/2 inch mortise prep with 5/8 inch radius corners, which is the corner profile used on most hollow metal frames and doors. If your existing hinge pockets have square corners instead, this one won't seat correctly and you want a square corner spring hinge like the Emtek 95013 in the same 3-1/2 by 3-1/2 size.

The DSH35R5/A ships as a pair, so one order covers two hinge locations. Common practice on a self-closing door is to run spring hinges in every hinge location, or at minimum pair one spring hinge with standard hinges and adjust tension until the door closes and latches on its own. On a three-hinge door that means ordering a pair plus one more hinge, or two pairs if you want all three plus a spare.

No. The DSH35R5/A is not an NRP hinge. On an out-swing exterior door where the barrel is exposed, that leaves the pin reachable from outside, so spec a hinge with a non-removable pin or add a security stud setup for that opening. For in-swing interior doors it makes no difference.

Not this one. The Deltana DSH35R5/A is 3-1/2 by 3-1/2 inches and will leave a gap in a 4 inch prep. For a 4 by 4 inch pocket with the same 5/8 inch radius, the Orca Hardware SPR4058 is the matching size and corner profile. Orca also makes the SPR4014 for 1/4 inch radius corners and the SPR4040 for square corners in that 4 inch size.

If the opening requires a listed spring hinge, the Design Hardware UL Spring Hinge is a medium duty spring hinge carried specifically as a UL item, and the Emtek 95013 is a UL listed spring hinge pair in 3-1/2" x 3-1/2" plated steel, which matches the Deltana's 3-1/2" x 3-1/2" size. The SOSS 216IC and 220IC invisible spring closer hinges carry a 20 minute fire rating.

The DSH35R5/A has 5/8" radius corners, which suits a routed frame prep. For a square corner prep, the Emtek 95013 is a 3-1/2" x 3-1/2" square corner spring hinge pair in plated steel, and the Hager 1250 is a standard weight steel full mortise spring hinge with square corners. The Orca SPR4040 and BEST 2060R are square corner spring hinges as well.

Single action. The DSH35R5/A swings one direction only, which is what you want on a standard door that closes into a frame and latches. If you need a door to swing both ways, such as a service or kitchen pass door, a single action hinge is the wrong choice.

That is the typical use. A pair of steel spring hinges closes the door from the hinge side with no arm or body on the face of the door, so nothing projects into the opening and there is nothing for tenants to unhook. Where you need controlled closing speed, backcheck, or hold open, a surface closer does things a spring hinge cannot.

It is classified for commercial use and built in steel with a plain bearing barrel. Plain bearing is the standard-weight construction used on medium frequency openings; for high traffic doors, heavy doors, or openings that see constant cycling, a ball bearing or heavy duty hinge is the better call.

The BEST RD2060R is a plain bearing radius corner spring hinge with a removable pin, standard weight and rated medium duty, so it is the nearest match in construction to the Deltana DSH35R5/A. BEST also offers the 2060R in square corners if your prep is not radiused.

If you want nothing visible on the edge of the door, the SOSS invisible spring closer hinges are the alternative to a surface butt hinge like the DSH35R5/A. The 216IC and 220IC series are heavy duty with a 20 minute fire rating, and the 218IC is a 7 inch heavy duty model requiring a minimum 1-3/4 inch door thickness. The 220IC needs a 2 inch minimum thickness, so check your door before specifying it.

The DSH35R5/A is a butt-style single action spring hinge pair sized 3-1/2" x 3-1/2" for a mortised door and frame. Toilet partition doors are normally hung on continuous spring loaded hinges instead: the Pemko Markar FM400 and FM900 series are full mortise spring loaded continuous hinges rated for an 80 lb load for toilet partitions, and the FS402 and FS902 series cover surface partition applications, with the FS902 in 304 stainless steel.

Both are steel full mortise spring hinges. The difference is the corner radius: the DSH35R5/A has 5/8" radius corners, while the Hager 1251 has 1/4" round corners. The Hager 1252 is the 5/8" round corner version in the same standard weight steel family. Match the radius to the existing hinge pocket in the frame. The Orca line splits the same way, with the SPR4014 at 1/4" radius and the SPR4058 at 5/8" radius in 4" x 4".

The DSH35R5/A is not supplied with a non-removable pin. The BEST RD2060R is a radius corner plain bearing spring hinge specified with a removable pin, and the BEST 2060R is the square corner version of the same removable pin hinge. Both are medium duty. If the security concern is pin access on an outswing door, an invisible hinge such as the SOSS 218IC removes the exposed barrel entirely, though it is a heavy duty hinge requiring a 1-3/4" minimum door thickness.

The DSH35R5/A is a 3-1/2" x 3-1/2" plain bearing steel spring hinge. For a larger, heavier leaf the McKinney 1502 is a 4-1/2" x 4-1/2" square corner full mortise standard weight spring hinge, and the Orca SPR4058 covers 4" x 4" with the same 5/8" radius corner profile. Where the door is thick enough, the SOSS 218IC and 220IC invisible spring closers are heavy duty units, the 220IC calling for a 2" minimum door thickness.

The DSH35R5/A is steel with an Oil Rubbed Bronze finish, which suits interior and protected openings. Where corrosion resistance drives the spec, the Hager 1150 is a full mortise spring hinge in standard weight stainless steel, and the Pemko Markar FS902 continuous spring loaded hinge is 304 stainless steel.

The DSH35R5/A is a 3-1/2" x 3-1/2" spring hinge with 5/8" radius corners and uses its standard leaf hole pattern. If the frame and door are already drilled for a staggered Z pattern, the Orca Hardware SPR4058Z is a 5/8" radius corner spring hinge built specifically with a Z hole pattern, in 4" x 4".

They do a similar job of self-closing a door but they are not a drop-in swap. The DSH35R5/A is a surface-visible butt hinge pair mortised into a 3-1/2" x 3-1/2" pocket. SOSS invisible spring closers such as the 216IC, 218IC and 220IC are heavy duty units concealed in the door edge, and they carry minimum door thickness requirements, 1-3/4" for the 218IC and 2" for the 220IC. Converting from butt hinges to invisible hinges means new mortises in both the door and frame.

Oil Rubbed Bronze is the finish on the DSH35R5/A. It pairs with oil rubbed bronze levers, pulls, and stops on the same opening. If your building is standardized on satin chrome or brass, this hinge will not match and you should pick a hinge in that finish rather than trying to blend.
