Deltana DE44058TT 4" x 4" x 5/8" Radius x Square Hinge, Steel (Pair)

The DE44058TT is a 4 x 4 inch full mortise hinge with 5/8 inch radius corners on one leaf and square corners on the other. That corner combination is what lets it drop into a router-cut 5/8 radius jamb prep or a square-chiseled one, so it covers both of the common preps you find on a 4 inch interior opening. If your existing hinge pocket is 3-1/2 x 3-1/2, this one is too big and you would need to re-mortise.

Yes, handing is a required choice: Right Hand or Left Hand. Because one leaf has 5/8 inch radius corners and the other is square, the hinge is not symmetrical, so the wrong hand puts the radius leaf on the wrong side of the opening. Stand outside the door, on the side it swings away from, and note which side the hinges are on.

The DE44058TT is not an NRP hinge, so the pin can be driven out from the barrel. That is fine on an interior door where the hinges are on the secure side. For an out-swinging door where the barrel is exposed on the outside, use a non-removable pin hinge instead, such as the Hager BB1168 NRP full mortise ball bearing hinge.

The Delaney RH40xx is the nearest match in size and corner profile: a 4 inch by 4 inch residential hinge with 5/8 inch radius by square corners, sold in pairs, the same combination the DE44058TT carries. The Deltana is a plain bearing steel hinge in 4 inch by 4 inch with 5/8 inch radius by square corners, also sold as a pair, so on a standard residential interior door the two drop into the same mortise. Deltana offers finishes from Oil Rubbed Bronze and Polished Brass through Prime Coat White and Paint Black; the Delaney is set up for Castlegate doors.

No. The DE44058TT is a 5/8 inch radius by square corner hinge, meaning one leaf carries the 5/8 inch radius. For a mortise routed fully square at 4 inch by 4 inch, the Orca Hardware COM4040 is a 4 inch by 4 inch square corner plain bearing hinge and matches the same plain bearing action the Deltana uses. The Delaney CH401X is another 4 inch by 4 inch square corner option, built as a ball bearing hinge.

Step up. The DE44058TT is a residential plain bearing hinge. For a commercial 4 inch by 4 inch opening, the Orca Hardware COM4040 is a medium duty commercial hinge in the same 4 inch by 4 inch size, and the Delaney CH401X is a 4 inch by 4 inch commercial ball bearing hinge. If the leaf size can grow, the Ives 3CB1HW is a heavy duty concealed bearing full mortise hinge, and the Don-Jo HWBB84545 is a heavy weight full mortise ball bearing hinge in 4-1/2 inch by 4-1/2 inch.

No. The DE44058TT is not a non-removable pin hinge, so on an out-swing where the barrel is on the outside it leaves the pin reachable. The Hager BB1168 NRP is a non-removable pin full mortise ball bearing heavy duty hinge and is the part to specify for that opening. It is a different bearing type than the Deltana plain bearing, so expect a heavier hinge and a matching heavier frame prep.

Bearing type and the traffic it takes. The DE44058TT is plain bearing steel, meant for indoor residential doors that get opened a handful of times a day. A ball bearing hinge carries a heavier door and a higher cycle count without wearing at the knuckle. Comparable 4 inch ball bearing options are the Orca Hardware 4040 Series square corner and the Delaney CH401X. If you are just replacing worn hinges on a bedroom or closet door, plain bearing is the right match.

Wood screws are included, #10 x 3/4 inch, which is what you want for a wood jamb and a wood door. If you are hanging into a hollow metal frame, these are the wrong fastener and you will need machine screws to match the frame's tapped holes.

One box is a pair, two hinges. A 4 x 4 interior door normally takes three hinges, so plan on two boxes per door and a spare leaf, or order in bulk: the case is 50 pairs. For a job standardizing many openings the case quantity is the efficient buy.

Both are residential plain bearing steel hinges sold as a pair. The split is size and corner: the Emtek 91013 is 3-1/2 inch by 3-1/2 inch with square corners in plated steel, while the DE44058TT is 4 inch by 4 inch with 5/8 inch radius by square corners. Match the hinge to the existing mortise - a 3-1/2 inch leaf will not fill a 4 inch cut. If you want the 3-1/2 inch size in a heavier build, the Emtek 92013 is a heavy duty plain bearing hinge in the same 3-1/2 inch by 3-1/2 inch square corner format.

The Delaney RH35xx is a 3-1/2 inch by 3-1/2 inch bulk steel residential interior hinge with 5/8 inch radius corners sold in pairs, the same residential steel and 5/8 inch radius character as the 4 inch by 4 inch DE44058TT. For a square corner 3-1/2 inch instead, the Schlage Residential S3P1010 is a 3-1/2 inch by 3-1/2 inch square corner plain bearing mortise hinge in packs of three, and the Ives 1010RP is a steel plain bearing residential hinge with square corners in sets of three.

They are not interchangeable in purpose. The ETH-CB70 is a 3 knuckle standard weight steel energy transfer hinge, built to carry wiring through the door to an electrified lock; the ETH-BB68 is the heavy duty 5 knuckle version of the same idea. The DE44058TT is a plain bearing steel hinge with no electrical path. Specify a transfer hinge only on the one leaf that needs power, and hang the remaining leaves on a matching mechanical hinge.

No, the DE44058TT is a plain bearing full mortise hinge with no closing spring. The Stanley Security 2060R is a full mortise spring hinge with square corners at 4.5 inch by 4.5 inch on a ferrous steel base, which is the part that pulls the door shut on its own. Note the leaf is 4.5 inch by 4.5 inch against the Deltana 4 inch by 4 inch, so the frame and door mortise have to be cut for the larger leaf.

No. The DE44058TT is a full mortise hinge, so both the door edge and the frame have to be prepped. When only one side can be cut, the Hager 1129 is a half mortise plain bearing commercial hinge in 4-1/2 inch standard weight steel, and it keeps the same plain bearing action. For a surface application on a frame that cannot be cut at all, the Hager 990 STEEL is a full surface hinge at 3 inch by 4 inch.

Eleven finishes, which is what makes it easy to match the rest of the trim in a building: oil rubbed bronze, brushed nickel, antique nickel, polished chrome, brushed chrome, zinc dichromate, polished brass, brushed brass, antique brass, prime coat white, and paint black. Prime coat white is the one to order when the hinge is going to be painted with the casing.

Not a drop-in. The Ives 3CB1 is a 3 knuckle concealed bearing full mortise hinge rated medium duty, and the Hager 920 is a 2 knuckle concealed bearing full mortise hinge, also medium duty. The DE44058TT is a plain bearing hinge rated residential. Both mount full mortise, but concealed bearing hinges hide the bearing inside the knuckle and are set up for heavier and higher-cycle openings, so confirm the mortise size and knuckle count before mixing them on the same door.

No. That opening calls for a purpose-built hinge: the BEST BB855 is a heavy duty steel double weight concealed ball bearing prison hinge in the detention hardware line, and the Stanley BB855 is a double weight prison hinge at 5 inch by 6 inch furnished with no holes and not swaged. The DE44058TT is a residential plain bearing hinge in 4 inch by 4 inch and is not built for that class of door.

The McKinney SQ3331 is a square barrel 2 knuckle decorative hinge at 4-1/2 inch by 4-1/2 inch, standard duty. The DE44058TT is a 4 inch by 4 inch steel hinge available in finishes including Oil Rubbed Bronze, Polished Brass, Antique Brass, Brushed Nickel and Polished Chrome, so if the look you want is finish-driven rather than barrel-driven the Deltana already covers a wide finish range at the smaller 4 inch leaf. Check the mortise, since the SQ3331 leaf is 4-1/2 inch by 4-1/2 inch.

No. The DE44058TT is a full mortise hinge ordered right hand or left hand, so it swings one direction. A double acting opening needs a pivot instead: the BEST DAP-3 is a heavy duty double acting pivot for commercial interior doors. That changes the door prep entirely, from hinge mortises in the edge to pivot preparation at the top and bottom.
