Delaney 4" x 4" Residential Spring Hinges for Castlegate, 5/8" Radius x Square (Pair)

The Delaney SP4056 is a spring hinge, so the spring inside the barrel pulls the door shut on its own. That's the point of it on a garage-to-house door or any opening that has to self-close without a closer hanging off the head. It's a residential-duty hinge, so it belongs on house doors, not on a high-traffic commercial opening where a Grade 1 closer would normally do the work.

Yes. The 4 x 4 Delaney spring hinge is UL listed for use with fire rated doors, which is what an inspector looks for on a self-closing rated opening like a garage-to-dwelling door. That listing is stated for this hinge specifically.

Spring hinges are handed, and the SP4056 comes as left hand or right hand only, so you have to pick. Stand outside the door, on the side it swings away from you. If the hinges are on your left, it's left hand; on your right, it's right hand. Order the pair that matches, because a spring hinge wound for the opposite hand won't pull the door closed.

They fit a 4 x 4 mortise with 5/8 inch radius corners on one leaf and square corners on the other. That radius x square combination is the tell: if your door was routed with a hinge template it likely has 5/8 radius pockets, and if the frame was cut square by hand you need the square leaf. Measure one existing hinge leaf before ordering. A 3-1/2 x 3-1/2 or 4-1/2 x 4-1/2 pocket will not take this hinge without recutting.

A door with its own closer does not need the spring in the hinge. In the same 4 inch x 4 inch leaf size, Orca Hardware offers a 4 inch x 4 inch square corner plain bearing commercial hinge and a 4 inch x 4 inch x 1/4 inch radius corner plain bearing commercial hinge, both medium duty. Pick the square corner version for a square mortise and the 1/4 inch radius version for a routed radius mortise. The Delaney Castlegate hinge stays the choice when the door has to close itself with no closer, since it is a spring hinge for automatic closing of doors.

They share the prep: the Deltana DE44R5TA is a 4 inch x 4 inch x 5/8 inch radius steel hinge sold as a pair, the same leaf size and 5/8 inch radius corner as the Delaney Castlegate hinge. What they do differs. The DE44R5TA is a security hinge, while the Delaney Castlegate is a 3 knuckle spring hinge for automatic closing of doors. Swapping to the Deltana means the door no longer closes on its own; swapping to the Delaney means giving up the security feature.

The Delaney Castlegate spring hinge is a 4 inch x 4 inch full mortise spring hinge with 5/8 inch radius x square corners, so it fits a 4 inch hinge prep. For a 4-1/2 inch prep, the Stanley Security 2060R is a full mortise spring hinge in 4.5 inch x 4.5 inch with square corners on a ferrous steel base, rated heavy duty. Both are self-closing spring hinges; the difference is leaf size and corner style, so match whichever one the existing mortise in the frame was cut for.

The Delaney Castlegate 4 inch x 4 inch spring hinge is a residential hinge in 0.106 inch gauge steel. For a commercial opening carrying heavy traffic, the Ives 3CB1HW is a steel heavy weight concealed bearing full mortise hinge with 3 knuckles, and the Don-Jo HWBB84545 is a heavy weight full mortise ball bearing hinge in 4-1/2 inch x 4-1/2 inch with a satin chrome finish. Both are heavy duty full mortise hinges; neither is self closing, so pair them with a door closer if the opening has to latch on its own.

It replaces the hinge but not the closing function. The Delaney Castlegate 4 inch x 4 inch hinge is UL listed for use with fire rated doors and is a spring hinge that closes the door automatically. The Ives 3CB1 is a steel 3 knuckle concealed bearing full mortise hinge rated medium duty, with no spring, so a fire door hung on it needs a separate self closing device to satisfy the latching requirement.

One box is a pair, two hinges. A standard residential door hung on three hinges usually gets two spring hinges plus one plain hinge, or three springs if the door is heavy or the closing action needs more pull, so most jobs take one to two boxes per opening. For a multi-unit rollout, they come 50 pair per carton at 50 lbs.

Screws are in the box. Each pair is packed with both wood screws and metal screws, so you're covered whether the frame is wood jamb or a hollow metal frame. Nothing else to order to hang them.

The knuckle is 3-knuckle steel at 0.106 inch gauge, which is a residential-weight hinge. It handles typical solid core and exterior residential doors on a house, but it is not a commercial heavy weight hinge. For a high-cycle commercial door, a heavy duty ball bearing hinge like the Don-Jo HWBB74545 at 4-1/2 x 4-1/2 is the right class instead.

For a commercial opening, the Stanley Security full mortise spring hinge in 4-1/2 x 4-1/2 with square corners is the heavy duty counterpart. It's a bigger hinge in a heavy duty class, so your frame prep has to be 4-1/2, not 4 x 4. The Delaney SP4056 stays on the residential side.

An interior passage door that does not need to self close can take a plain residential hinge. The Emtek 91013 is a residential plain bearing hinge pair, 3-1/2 inch x 3-1/2 inch with square corners in plated steel, and the Deltana DSB35 is a 3-1/2 inch x 3-1/2 inch square residential hinge pair. Both are a smaller leaf than the Delaney Castlegate 4 inch x 4 inch, so confirm the door prep before ordering. Where the door must return to the latch by itself, stay with the spring hinge.

No. The McKinney MP79 MacPro is a 5 knuckle standard weight full mortise hinge. The Delaney Castlegate is a 3 knuckle spring full mortise hinge, 4 inch x 4 inch in 0.106 inch gauge steel with 5/8 inch radius x square corners, packed one pair with wood and metal screws. The knuckle count and the spring are the practical difference: the MP79 is a plain hanging hinge, and the Castlegate carries the closing spring inside the barrel.

They cover different jobs on the same unit. The Delaney Castlegate is a 4 inch x 4 inch residential spring full mortise hinge in US26D dull chrome, packed one pair per box, 50 pair per carton, and UL listed for use with fire rated doors, which suits the corridor entry door that has to close and latch. The Ives 1010RP is a steel plain bearing residential hinge with square corners sold as a set of three, medium duty, which suits the interior passage doors. Standardizing usually means both: spring hinges at the self closing openings, plain bearing everywhere else.

US26D dull chrome, which is the satin chrome tone that matches the vast majority of satin nickel and satin chrome levers and deadbolts on residential and light commercial openings. The base is steel. If your building is standardized on satin chrome trim, these blend into the fleet.
