Deltana DSB4N 4" x 4" Square Hinges, NRP (Pair)

NRP stands for non-removable pin. The DSB4N ships with the pin secured so it can't be driven out while the door is closed. That matters on any outswing door, where the hinge barrel sits on the outside: without NRP, someone can pull the pin and lift the door off the frame regardless of what lock is on it. On an inswing interior door the barrel is on the secure side, so NRP buys you nothing there. If you are hanging an outswing entry, patio, or garage-to-house door, this is the version you want.

No. The DSB4N is a residential-duty plain bearing hinge. Plain bearing means the knuckles ride on each other with no ball bearing race, which is fine for a house door opened a few dozen times a day but wears and starts to sag under commercial traffic. For a corridor, office, or any high-cycle opening, move to a bearing hinge: the Orca Hardware 4040 Series is a 4 x 4 square corner commercial hinge, and the Delaney CH401X is a 4 x 4 commercial ball bearing hinge with square corners. Both keep the same 4 x 4 square corner prep, so the door and jamb mortises carry over.

The DSB4N is a 4" x 4" hinge and will not fit a 3-1/2 inch mortise without recutting the prep. At 3-1/2" x 3-1/2" with square corners, the Emtek 91013 is a residential plain bearing hinge pair in plated steel, matching the DSB4N's plain bearing action; the Emtek 92013 is the heavy duty plain bearing version at the same 3-1/2" x 3-1/2" square corner size. The Schlage Residential S3P1010 is a 3.5" x 3.5" square corner plain bearing mortise hinge sold in packs of three, which suits a door hung on three hinges without ordering a pair plus a single.

The Orca Hardware 4040 Series is a 4" x 4" square corner plain bearing commercial hinge, matching the DSB4N on size, corner style, and bearing type. The DSB4N is solid brass with a .129 leaf thickness and ships as a pair with non-removable pins; the Orca 4040 is rated medium duty for commercial openings. Choose the Deltana where the brass finish is part of the decorative package, and the Orca where the opening is a painted commercial door and the finish does not need to match a decorative suite.

The DSB4N is a plain bearing hinge specified for residential use. For a commercial opening cycling heavily, a ball bearing hinge is the usual choice: the Delaney CH401X is a 4" x 4" commercial ball bearing hinge with square corners at the same leaf size, and the Orca Hardware 3535 Series is a 4-1/2" x 4-1/2" square corner ball bearing commercial hinge, medium duty, for openings prepped to the larger 4-1/2 inch mortise. Both keep the square corner prep the DSB4N uses.

The Hager BB1168 is a non-removable pin full mortise ball bearing hinge rated heavy duty. Like the DSB4N it carries the NRP feature that keeps the pin from being driven out on an out-swing door where the barrel is on the exterior, but it is a ball bearing heavy duty hinge rather than the DSB4N's residential plain bearing solid brass build. Use the BB1168 where the security concern comes with commercial traffic, and the DSB4N where the out-swing door is residential and the brass finish is part of the decorative package.

No. The DSB4N is a solid brass plain bearing hinge with no wiring path. For a powered opening, the Command Access ETH-CB70 is an energy transfer hinge on a 3-knuckle standard weight steel base rated medium duty, and the ETH-BB68 is the 5-knuckle heavy duty version. If the opening also needs door position monitoring, the Command Access ETM-CB70 carries an integrated door position sensor on a 3-knuckle steel base, and the BEST CECB179-12C is a steel full mortise concealed bearing electrified hinge with a 12-wire quick connect.

The DSB4N is a full mortise hinge, meaning both leaves mortise into the door and the frame. Where the frame will not take a mortise, the Hager 1129 is a half mortise plain bearing commercial hinge in 4-1/2" standard weight steel, rated heavy duty, which mortises into the door and surface-applies to the frame. The Hager 990 STEEL is a full surface hinge at 3" x 4" with a welded tip, heavy duty, for openings where neither leaf can be mortised.

The DSB4N is sold by the pair, two hinges per order. A standard interior door takes three hinges and a heavier exterior or solid core door takes three or four, so one pair does not hang a door on its own. Order two pairs for a three-hinge door (you'll have one spare) or two pairs for a four-hinge opening. Buy all of them in one go so the finish batches match.

Wood screws are specified with the hinge at #12 x 1-1/4 inch. That length bites the door stile and jamb but does not reach the framing behind the jamb. On an exterior door or anything heavy, swap the jamb-side center screw for a longer screw that runs through the jamb into the stud, which is what stops the door sagging over time.

Twelve finishes: PVD Polished Brass, Polished Brass, Antique Brass, Bronze Anodized, Oil Rubbed Bronze, Bronze Dark, Bronze Medium, Bronze Rust, White Medium, Brushed Nickel, Polished Chrome, and Brushed Chrome. If you're matching existing hardware on the other doors, note that PVD Polished Brass and plain Polished Brass are different products: PVD is a physical vapor deposition coating that holds up outdoors, standard polished brass is lacquered and will patina. Pick one and stay with it across the opening.

Solid brass, both the material and the substrate. That's the reason to pick these over a plated steel residential hinge such as the Emtek 91013: a solid brass leaf won't rust through where a plated steel one gets chipped, which matters on a coastal or exterior opening. The leaf thickness is .129 inch.

No handing to specify. A full mortise butt hinge like the DSB4N is symmetrical, so the same pair works on a left hand or right hand door. What you do decide is which face the barrel ends up on, and that's what makes the NRP version worth ordering: on an outswing door the barrel is on the unsecured side, and the non-removable pin keeps the door from being lifted off. Spring hinges and some electrified hinges are handed, this one isn't.

No. The DSB4N is a plain bearing butt hinge with no spring, so it holds the door wherever you leave it. For a self-closing opening, such as a garage-to-house door that has to latch on its own, use a spring hinge instead. The Stanley Security 2060R full mortise spring hinge in 4-1/2 x 4-1/2 with square corners is the option to look at, though the larger leaf means a different mortise than a 4 x 4.

Not as a direct drop-in. The Delaney RH45xx is a 4" x 4" exterior residential hinge pair with a 5/8" radius corner, so it is cut for a radius mortise while the DSB4N has square corners. The Delaney RH40xx Castlegate hinge is a 4" x 4" residential pair offered in 5/8" radius and square, and the square version matches the DSB4N's corner prep at the same leaf size. Confirm which corner the door is routed for before ordering either.

They are different builds for different openings. The Ives 3CB1 is a steel 3-knuckle concealed bearing full mortise hinge rated medium duty for commercial use, and the 3CB1HW is the heavy weight concealed bearing version. The DSB4N is a solid brass full mortise hinge with plain bearings, square corners, and non-removable pins, sold as a pair for residential openings. Both mount full mortise, but a concealed bearing hinge hides the bearing between knuckles and carries a commercial duty rating, while the DSB4N is a decorative brass hinge that accepts finials.

The McKinney SQ3331 is a square barrel 2-knuckle decorative hinge at 4-1/2" by 4-1/2", rated standard duty. The DSB4N is a 4" x 4" solid brass hinge that can be fitted with decorative finials, so the decorative treatment sits at the tips rather than in the barrel profile. The two also differ in prep size, so check whether the door is routed for a 4 inch or 4-1/2 inch leaf before choosing.

The DSB4N is solid brass throughout, which is the reason it holds up where plated steel does not. The McKinney T2314 is a non-ferrous standard weight 5-knuckle hinge rated medium duty and is the closest alternative when a non-ferrous base metal is required at a larger commercial leaf. Among the Don-Jo heavy weight full mortise ball bearing hinges, the HWBB85045 is brass at 5" x 4-1/2" in satin chrome, while the HWBB75045 at the same 5" x 4-1/2" size is steel.

No. The DSB4N is a residential solid brass hinge. Detention openings use purpose-built hinges: the BEST BB855 is a heavy-duty steel double weight concealed ball bearing prison hinge, and the Stanley Security BB855 is a double weight prison hinge at 5" by 6" furnished with no holes and not swaged, rated heavy duty, so it can be welded and drilled to the frame condition on site.

Yes, the Deltana solid brass square hinges accept decorative finials in place of the standard tips, which is how you match a hinge to ball tip or urn tip hardware elsewhere in the house. Finials are a separate order, they do not come with the hinge pair.

The Emtek 94013 is a heavy duty ball bearing hinge pair at 3-1/2" x 3-1/2" with square corners in plated steel, so the bearings carry the load on a heavier door but the leaf is smaller. The DSB4N is a plain bearing solid brass pair at 4" x 4" with square corners. The corner prep matches on both; the leaf size and the bearing type do not, so the 94013 fits a 3-1/2 inch mortise while the DSB4N needs a 4 inch one.

They serve the same plain bearing residential role but differ in how they are packaged and sized. The Ives 1010RP is a steel plain bearing residential hinge with square corners sold as a set of three, rated medium duty, which covers one door hung on three hinges. The DSB4N is a solid brass pair with square corners and non-removable pins at 4" x 4", so two pairs cover three-hinge doors with one leaf left over. Match the leaf size to the existing mortise before substituting.
