Deltana SS44058TT 4" x 4" x 5/8" Radius x Square Corners Hinges, Steel, Residential / Security Stud (Pair)

If the door and jamb are already routed for a 4 x 4 hinge with 5/8 inch radius corners, the SS44058TT drops straight in with no chisel work. That corner profile is what a router with a hinge template cuts, and it's the standard residential prep on most pre-hung wood doors. One thing to check: the SS44058TT is radius on one leaf and square on the other, so it suits a door mortised with radius corners hung in a jamb with square corners. If both your door and frame are square-cornered, or both radius, you want a matched hinge instead.

Yes, handing has to be specified. Every finish on the SS44058TT is sold as a left hand or a right hand pair, because the security stud sits on one leaf and has to line up with the hole on the other for the swing you have. Stand outside the door on the side it swings away from: hinges on your left is left hand, hinges on your right is right hand. Ordinary plain hinges are handless, but this one is not.

Residential duty, plain bearing. That means interior and exterior doors on houses, apartments, and light-traffic multi-family units, not a corridor or entry that cycles all day. Plain bearing hinges wear under continuous traffic. For a commercial opening, step up to a ball bearing or concealed bearing hinge like the Orca Hardware 4040 Series 4 x 4 square corner commercial hinge, the Delaney CH401X 4 x 4 commercial ball bearing hinge, or an Ives 3CB1 concealed bearing full mortise hinge.

Not without recutting. A 4 x 4 hinge needs a mortise a half inch longer on each door and jamb than a 3-1/2 inch hinge, and the screw holes won't line up. If your doors are prepped for 3-1/2 inch, stay at that size, with something like the Emtek 91013 residential plain bearing pair or the Schlage Residential S3P1010, both 3-1/2 x 3-1/2. The Deltana SS44058TT is 4 x 4 and belongs on a door already cut for 4 inch hinges.

The SS44058TT is not an NRP hinge. It uses the security stud instead, which interlocks the two leaves whenever the door is closed and blocks the door from being lifted out even if the pin is pulled. For most residential outswing doors that solves the same problem. If your spec sheet or insurer specifically calls for a set-screw NRP hinge, the Hager BB1168 NRP is a non-removable pin full mortise ball bearing hinge.

The Delaney RH40xx is the nearest match on mortise profile: it is a 4" x 4" residential hinge pair with a 5/8" radius x square corner, the same corner geometry the Deltana SS44058TT carries. Both drop into an existing 4 x 4 mortise routed with a 5/8 inch radius on one pair of corners and square on the other, so no jamb or door rework is needed. The Deltana SS44058TT is steel with a plain bearing and adds a security stud option; the Delaney RH40xx is part of the Castlegate hinge line. For an exterior residential opening in the same size and corner profile, the Delaney RH45xx is a 4" x 4" pair with a 5/8" radius as well.

The Deltana SS44058TT is rated residential. For a 4 x 4 commercial opening, the Orca Hardware 4040 Series is a 4" x 4" square corner plain bearing commercial hinge rated medium duty, and the Orca Hardware 4014 Series is the same 4" x 4" size in a 1/4" radius corner, also medium duty plain bearing. Both share the plain bearing type the Deltana SS44058TT uses, in a commercial duty rating. Where a bearing upgrade is wanted at 4 x 4, the Delaney CH401X is a 4" x 4" commercial ball bearing hinge with a square corner. Note the corner profile: the Deltana SS44058TT is 5/8" radius x square, so an existing mortise cut for it will not match a 1/4" radius or full square corner without rework.

Wood screws are included: #10 x 3/4 inch. That length is sized for a wood door and wood jamb. If you're hanging a heavier slab or a solid-core exterior door, a common trick is to swap the two center jamb-leaf screws for 3 inch screws that reach the stud behind the frame, which does far more for sag than the hinge itself. The included screws do not suit a steel frame.

The SS44058TT is sold by the pair, so a standard three-hinge door needs two pairs and leaves you one spare hinge. Most interior and exterior residential doors up to 7 feet use three hinges. If you're doing a run of doors in a building, order in even pairs and plan the spare into the count.

Leaf gauge is 0.085 inches of steel. That's a residential-weight leaf, fine for hollow core and typical solid core wood doors in a house or apartment, but it's the number to check against your mortise depth if you're replacing a heavier hinge, since a thicker outgoing hinge leaves a deeper pocket. For heavy wood or metal doors on a commercial opening, a heavy weight hinge such as the Don-Jo HWBB84545 is the class you want, not a residential plain bearing.

Full mortise: both leaves recess into pockets cut in the door edge and the jamb, so nothing sits proud when the door is shut. It is not a surface-applied hinge and it will not work on a door with no mortise cut unless you rout for it. The screw holes follow an arc pattern on the leaf, which is the usual residential layout.

Delaney's 4 x 4 residential hinges with 5/8 inch radius corners cover the same opening in the same corner profile: the RH45xx exterior residential pair or the RH40xx Castlegate pair. Both are 4 x 4 radius hinges sold by the pair, so the mortise prep matches. What you give up is the security tab, so if you're hanging an out-swinging exterior door where the pins are accessible from outside, stay with the SS44058TT.

No, they defeat different attacks. The Deltana SS44058TT is a plain bearing steel hinge with a security stud option and is not a non-removable pin hinge; the stud interlocks the two leaves so the door cannot be lifted out of the frame even if the pin is driven, while the pin itself remains removable. A non-removable pin hinge instead fixes the pin in place with a set screw. The Hager BB1168 is a non-removable pin full mortise ball bearing hinge rated heavy duty, which is the part to specify when the spec calls for NRP explicitly on an outswing exterior door.

Only if the mortise matches. The Deltana SS44058TT is a full mortise 4" x 4" hinge with 5/8" radius x square corners. The Don-Jo HWBB74545 and HWBB84545 are heavy weight full mortise ball bearing hinges at 4-1/2" x 4-1/2", and the Don-Jo HWBB75045 is 5" x 4-1/2" steel; all three are larger than the 4 x 4 cutout and require the door and jamb to be re-routed. The Orca Hardware 4040 Series stays at 4" x 4" but is a square corner, so it also does not sit in a 5/8 inch radius mortise without filling. When the existing cutout has to be reused as-is, stay with the 4 x 4 x 5/8 inch radius x square profile.

The Deltana SS44058TT is a plain bearing steel hinge with no wire path through the barrel, so power has to come from an electric power transfer or a different hinge entirely. Command Access ETH-CB70 is an energy transfer hinge with a 3 knuckle standard weight steel base rated medium duty, and the ETH-BB68 is the 5 knuckle heavy duty version of the same idea. Where the opening also has to report whether the door is closed, the Command Access ETM-CB70 adds door position sensing on a 3 knuckle steel base, and the ETM-BB68 is an energy transfer monitor hinge with an integrated door position switch at heavy duty. The Stanley CECB1900R54L is a 3 knuckle concealed bearing concealed conductor hinge, steel full mortise, 4-1/2" x 4-1/2" square corner, left-handed, 4-wire.

Two families read as close matches on paper and are not. The Hager 1129 is a half mortise plain bearing commercial hinge at 4-1/2" standard weight steel - it shares the plain bearing type but half mortise means one leaf surface-mounts to the frame rather than sitting in a routed pocket, unlike the full mortise Deltana SS44058TT. The BEST DAP-3 is a heavy duty double acting pivot for commercial interior doors, which hangs the door on the floor and head instead of the jamb edge entirely. Neither drops into a 4 x 4 hinge mortise.

Nine finishes across the SS44058TT: Oil Rubbed Bronze, Brushed Nickel, Antique Nickel, Polished Chrome, Brushed Chrome, Zinc Dichromate, US3/4, and Prime Coat White. For a paint-grade job where the hinge disappears into the trim, Prime Coat White takes paint directly. Zinc Dichromate is the utility finish for a door nobody looks at, like a garage or basement. The rest are the decorative options for matching visible hardware on the same door.

Steel, both substrate and finish base. Steel hinges are standard on residential exterior doors, and the plated and coated finishes here are what carry the corrosion protection, so the finish choice matters more than the base metal outdoors. In a coastal or heavy-salt environment, a non-ferrous hinge such as the McKinney T2314 is the material change to make.

The Deltana SS44058TT ships as a pair, so a three-hinge door takes two orders per opening plus a spare leaf. Where the count matters, the Ives 1010RP is a steel plain bearing residential hinge with square corners supplied as a set of three and rated medium duty, and the Schlage Residential S3P1010 is a 3.5" x 3.5" square corner plain bearing mortise hinge in packs of three. Both are 3-1/2 inch square corner parts, so they suit doors mortised that way rather than the 4" x 4" x 5/8" radius x square profile the Deltana SS44058TT is cut for. For a 4 x 4 radius mortise standard across the property, the Delaney RH40xx and RH45xx are the pair-packed 4" x 4" 5/8" radius options for interior and exterior openings.

No. The Deltana SS44058TT is a residential plain bearing steel hinge, and the security stud addresses door lifting on a normal residential opening. Detention and high-abuse openings use purpose-built hardware: the BEST BB855 is a heavy-duty steel double weight concealed ball bearing prison hinge, the Stanley BB855 is a double weight prison hinge at 5" by 6" furnished with no holes and not swaged, and the Hager 990 STEEL is a full surface prison hinge at 3" x 4" with a welded tip, rated heavy duty. These mount and prep differently from a 4 x 4 full mortise residential hinge.
