Delaney 4" x 4" Spring Hinges, Square Corner (Pair)

That is exactly what the Delaney 4 x 4 spring hinge is for. It is a 3-knuckle full mortise hinge with a spring in the barrel that pulls the door shut on its own, so there is no closer body or arm on the door face. It is UL listed for use on fire rated doors, which is the usual reason a self-closing hinge gets specified in the first place. Where a hydraulic closer gives you adjustable sweep and latch speed, a spring hinge does not, so on a heavy or high-traffic opening a closer is still the better control.

Yes. Size is 4 x 4 inches with square corners, so they seat in an existing square-corner 4 inch mortise with no rework. If the existing pocket has radius corners, you would need a radius hinge instead, such as the Orca Hardware 4 x 4 x 1/4 inch radius corner hinge.

They are 0.106 inch gauge steel and catalogued as residential duty, so they suit apartment, garage-to-house and interior residential self-closing doors. For a commercial-weight opening, the Stanley Security 2060R full mortise spring hinge in 4-1/2 x 4-1/2 square corner is listed as heavy duty and is the better fit.

The Delaney 4 x 4 spring hinge is UL listed for use with fire rated doors, which is what a self-closing hinge has to be to serve on a rated opening such as a unit entry or a garage-to-dwelling door. The hinge is UL listed as a component; the door and frame assembly still has to carry its own label.

The Delaney 4" x 4" spring hinge is a 3-knuckle full mortise self-closing hinge with square corners in 0.106" steel. For a wider leaf on the same kind of self-closing opening, the Stanley Security 2060R is a full mortise spring hinge, also square corner, at 4.5" x 4.5" on a ferrous steel base and rated heavy duty. Confirm the door's existing hinge mortise is cut for the larger 4-1/2" leaf before switching.

It will fit the same mortise pattern but it will not close the door. The Delaney 4" x 4" spring hinge is built for automatic closing of doors, while the Orca Hardware 4040 Series is a 4" x 4" square corner plain bearing commercial hinge with no closing spring. Use the plain bearing hinge only where a separate door closer handles closing, or where the door is meant to stay where it is put.

The Delaney 4" x 4" spring hinge has square corners, so it will leave gaps in a radius pocket. The Orca Hardware 4014 Series is a 4" x 4" hinge with 1/4" radius corners, plain bearing, and the Deltana DE44R5TA is a 4" x 4" hinge with 5/8" radius corners in steel, supplied as a pair. Match the pocket radius, and note neither of those radius hinges is self-closing.

One box covers one pair, two hinges. Most self-closing installs use at least two spring hinges on a door, and adding a third spring hinge increases closing force on a heavier or wider leaf. If you are hanging a door on three hinges, one common approach is two spring hinges plus a matching plain hinge; ordering two pairs gives you spares as well.

Both wood and metal screws ship in the box, so you are covered whether you are fastening into a wood jamb or a hollow metal frame. Nothing else has to be ordered to hang the hinge.

A plain or ball bearing hinge only carries the door, it will not push it closed, so swapping to one will not solve a door that stays open. Spring hinges are the fix. If the door already closes fine and the problem is drag or wear, then a bearing hinge in the same 4 x 4 square corner size, like the Orca Hardware 4040 Series plain bearing hinge, is the straight replacement.

No handing to specify. The Delaney 4 x 4 spring hinge is ordered by size and finish only, with square corners on both leaves. Spring tension is set after installation with the tension pin and wrench method, so the same hinge serves either swing.

The Delaney 4" x 4" spring hinge is classed as residential and is UL listed for use with fire rated doors. For higher-cycle commercial openings the usual moves are a heavy weight bearing hinge such as the Ives 3CB1HW, a 3-knuckle concealed bearing full mortise steel hinge rated heavy duty, or the Hager BB1168, a full mortise ball bearing heavy duty hinge with a non-removable pin. Those are not self-closing, so a surface or concealed closer would carry the closing function.

The Delaney spring hinge is a 4" x 4" leaf and will not drop into a 3-1/2" prep without recutting. On a 3-1/2" square corner prep, options include the Emtek 91013 residential plain bearing hinge pair in plated steel with square corners, the Deltana DSB35 3-1/2" x 3-1/2" residential square hinge pair, and the Schlage Residential S3P1010 3-1/2" x 3-1/2" square corner plain bearing mortise hinges in a pack of three. None of those provide the automatic closing the Delaney does.

No - they solve different problems. The Delaney 4" x 4" spring hinge supplies automatic closing and carries no wiring. Energy transfer hinges such as the Command Access ETH-CB70, a 3-knuckle standard weight steel base hinge, or the BEST CECB179-12C full mortise concealed bearing electrified hinge with 12-wire quick connect, pass power to an electrified lock but do not close the door. An opening that needs both power transfer and self-closing generally uses an energy transfer hinge plus a separate closer.

The Delaney 4" x 4" spring hinge is a 3-knuckle full mortise steel hinge with square corners. Where the pin must not be pulled from the hinge side of an outswing door, the Hager BB1168 is a full mortise ball bearing heavy duty hinge with a non-removable pin, and the Deltana CSB45N is a 4-1/2" x 4-1/2" square hinge pair with an NRP pin. Both are larger or non-spring, so plan the mortise and a separate closing device accordingly.

Two: US26D dull chrome, and 613 satin bronze oil-rubbed. US26D is the one to pick if the other hardware on the opening is satin chrome or satin nickel-toned; 613 matches dark oil-rubbed bronze levers and deadbolts.

The Delaney 4" x 4" spring hinge is a full mortise hinge that closes a door swinging one direction. A door that must swing both ways uses a pivot instead - the BEST DAP-3 is a heavy duty double acting pivot for commercial interior doors. That is a floor and head mounted pivot set, not a hinge that fits a standard 4" x 4" mortise, so frame and floor prep differ entirely.

Not functionally. The Delaney is a 3-knuckle spring hinge in 0.106" steel built to close the door on its own. The McKinney MP79 MacPro is a 5-knuckle full mortise hinge at standard weight, and the Stanley FBB191 is a 5-knuckle full mortise standard weight hinge at 4.5" x 4.5". Both are free-swinging, and the Stanley's larger leaf needs a 4-1/2" mortise.
