Deltana SS44058TTNRP 4" x 4" x 5/8" Radius x Square Corners Hinges, Riveted NRP / TT, Stainless Steel (Pair)

Yes. The SS44058TTNRP measures 4 inches by 4 inches, which is the common size for residential entry and interior doors already prepped for a 4 inch hinge. The corner style is 5/8 inch radius on one leaf and square on the other, so it drops into a router-cut 5/8 radius jamb pocket and a square-cut door edge, or vice versa depending on how your opening was machined. If both your existing hinge leaves have square corners or both have radius corners, this combination will not match your existing cutouts.

NRP stands for non-removable pin. The SS44058TTNRP carries a set screw arrangement that keeps the pin from being driven out while the door is closed. It matters on any out-swinging exterior door, where the hinge barrels are on the outside of the building and an intruder could otherwise pull the pin and lift the door off. On an in-swinging door the barrels are protected anyway, so NRP is optional there.

That is exactly what they are made for. The SS44058TTNRP is stainless steel through the body, not plated steel, so it holds up against salt air and moisture far better than a standard steel hinge that will bloom rust at the barrel and screw heads. Property managers with waterfront or poolside units use stainless for that reason. The finish supplied is brushed stainless.

Residential. The SS44058TTNRP is a plain bearing hinge, which means the knuckles ride metal on metal rather than on ball or concealed bearings. That is fine for a house or an apartment door that cycles a few dozen times a day. For a commercial entrance, a stairwell, or anything with a closer on it, step up to a bearing hinge such as the Orca Hardware 4014 Series 4 inch plain bearing commercial hinge or a ball bearing unit like the Delaney CH401X 4 inch commercial ball bearing hinge.

Not for a commercial opening. The Deltana SS44 is a residential duty plain bearing hinge, even though it does have the non-removable pin. For a commercial out-swing door, the Hager BB1168 is a non-removable pin full mortise ball bearing hinge rated heavy duty and is the closer match.

The Delaney RH40xx is a 4 inch by 4 inch residential hinge pair with a 5/8 inch radius by square corner pattern, the same corner combination the Deltana SS44058TTNRP uses, so it drops into the same mortise without re-routing. The Deltana is stainless steel with a non-removable pin, while the Delaney RH40xx is part of the Castlegate hinge line. If the door is exterior, Delaney also lists the RH45xx as a 4 inch by 4 inch exterior residential hinge pair with 5/8 inch radius corners.

The Deltana SS44058TTNRP is classified for residential use. For a commercial 4 inch by 4 inch opening, Orca Hardware lists the COM4040 as a 4 inch by 4 inch square corner plain bearing commercial hinge rated medium duty, and the COM4014 as a 4 inch by 4 inch plain bearing commercial hinge with a 1/4 inch radius corner, also medium duty. Both carry the same plain bearing type as the Deltana, so pick by corner pattern: COM4040 for a square-cornered mortise, COM4014 if the frame prep has a 1/4 inch radius.

The Deltana SS44058TTNRP is a 4 inch by 4 inch hinge with a non-removable pin. For a larger or heavier outswing leaf, the Hager BB1168 is a non-removable pin full mortise ball bearing hinge rated heavy duty. The Hager uses ball bearings rather than the Deltana's plain bearing, which is the usual choice when the door weight or cycle count goes up.

The SS44058TTNRP is sold by the pair, two hinges. Most 4 inch residential doors use three hinges, so plan on ordering two pairs per door and keeping the spare, or order in volume, the case runs 50 pairs. Taller or heavier doors may take four.

A plain bearing hinge like the Deltana SS44 has knuckles that bear directly on one another. It is quieter to install, costs less, and is the right pick for a normal-weight door with no closer. A ball bearing hinge puts hardened bearings between the knuckles so the door can carry more weight and swing thousands more cycles without wear or sag. If you are hanging a heavy solid core or a door with a closer, look at a ball bearing option such as the Don-Jo HWBB74545 heavy weight full mortise ball bearing hinge or the Orca 3535 Series ball bearing commercial hinge.

Yes, it is a full mortise hinge. Both leaves get recessed, one into the door edge and one into the jamb, so the leaves sit flush and the door closes tight. It is not a surface-applied or half mortise hinge, so if your frame is a hollow metal one prepped only on the jamb face you would need a half mortise type instead, such as the Hager 1129 half mortise plain bearing hinge.

No. The Emtek 91013 is a 3-1/2 inch by 3-1/2 inch plain bearing residential hinge pair in plated steel with square corners, so the leaf is half an inch shorter and narrower than the Deltana SS44058TTNRP's 4 inch by 4 inch size and it will not fill an existing 4 inch mortise. The Emtek also has square corners throughout, while the Deltana is 5/8 inch radius by square. Other 3-1/2 inch options in the same size class include the Schlage Residential S3P1010 square corner plain bearing hinge and the Delaney RH35xx with 5/8 inch radius corners.

The Deltana SS44058TTNRP uses a plain bearing, so it does not meet a ball bearing callout. In a 4 inch by 4 inch footprint, the Delaney CH401X is a 4 inch by 4 inch commercial ball bearing hinge with a square corner. At 4-1/2 inch by 4-1/2 inch, the Orca COM3535 is a square corner ball bearing commercial hinge rated medium duty, and Don-Jo lists the HWBB74545 and HWBB84545 as 4-1/2 inch by 4-1/2 inch heavy weight full mortise ball bearing hinges in satin chrome.

No, the Deltana SS44058TTNRP is a mechanical full mortise hinge with no wire path. For power transfer through the hinge, Command Access lists the ETH-CB70 as a 3 knuckle standard weight steel base energy transfer hinge rated medium duty and the ETH-BB68 as a 5 knuckle heavy duty version. If the opening also needs door position monitoring, the ETM-CB70 adds door position sensing on the 3 knuckle steel base and the ETM-BB68 includes an integrated door position switch. BEST also offers the CECB179-12C, a steel full mortise concealed bearing electrified hinge with a 12 wire quick connect.

The Deltana SS44058TTNRP is a standard full mortise hinge with no spring, so it will not return the door. The Stanley Security 2060R is a full mortise spring hinge with square corners at 4-1/2 inch by 4-1/2 inch on a ferrous steel base, rated heavy duty. Note the size step up from the Deltana's 4 inch by 4 inch leaf, so the mortise will need to be enlarged on a retrofit.

No. The Deltana SS44058TTNRP is a full mortise hinge, meaning both leaves recess into the door and the frame. Where the frame cannot be mortised, the Hager 1129 is a half mortise plain bearing commercial hinge in 4-1/2 inch standard weight steel, and the Hager 990 STEEL is a full surface hinge at 3 inch by 4 inch with a welded tip, both rated heavy duty. Half mortise mortises the door leaf only; full surface applies to the face of both door and frame.

The Deltana SS44058TTNRP is stainless steel throughout, which is why it is specified for waterside and outdoor openings where corrosion resistance matters. Plated steel peers such as the Emtek 91013 and 92013 plain bearing hinge pairs and the Emtek 94013 ball bearing pair are described as plated steel, a base metal with a surface coating rather than a corrosion-resistant substrate. If you want a non-ferrous alternative rather than stainless, the McKinney T2314 is a non-ferrous standard weight 5 knuckle hinge rated medium duty.

TT identifies the riveted tip and pin construction on this Deltana stainless hinge, supplied together with the NRP non-removable pin feature. It is part of the model designation, so ordering SS44058TTNRP gets you both the riveted TT build and the NRP set screw.

The Deltana SS44058TTNRP uses a plain bearing, where the knuckles ride directly on one another, and is a 4 inch by 4 inch stainless steel pair with a non-removable pin. The Ives 3CB1 is a 3 knuckle concealed bearing steel full mortise hinge rated medium duty, with the bearing hidden inside the knuckle so the barrel reads as a smooth cylinder. Ives also lists the 3CB1HW as a heavy weight concealed bearing full mortise version, and Hager offers the 920, a 2 knuckle full mortise concealed plain bearing hinge rated medium duty.

The Deltana SS44058TTNRP already has a non-removable pin, which addresses pin-pulling on an outswing door. It does not address forced-entry or detention-level abuse. For those openings, the BEST BB855 is a heavy-duty steel double weight concealed ball bearing prison hinge and the Stanley BB855 is a double weight prison hinge at 5 inch by 6 inch furnished with no holes and not swaged. Both are considerably larger and heavier than the Deltana's 4 inch by 4 inch leaf.
