Deltana SS44R4 4" x 4" x 1/4" Radius Corner Hinge, Stainless Steel (Pair)

That's exactly what the SS44 Series is for. The SS44R4 is stainless steel through the leaf, not plated, so it resists corrosion far better than a plated steel hinge on a coastal or exposed opening. If the door is on a waterfront property, a pool deck, or any exterior it sees weather on, stainless is the material to specify.

1/4 inch radius corners. That matters because the mortise in the door and frame has to match: a router-cut prep leaves rounded corners, and a 1/4 inch radius leaf drops straight into it. If the existing openings were prepped with a chisel for square corners, this leaf will not sit right and you want a square corner hinge instead.

It is a 4 x 4 inch full mortise hinge, so both leaves recess into the door edge and the frame. Leaf thickness is .085, which is what the depth of your mortise needs to match so the leaf sits flush. A 4 x 4 leaf is the common size for a 1-3/4 inch door; the leaf width has to cover the door edge and still leave room for the barrel to clear the stop.

Plain bearing. A plain bearing hinge runs metal on metal at the knuckle, which is fine for a door opened by hand at normal traffic. Put a closer on the door, hang a heavy solid core or metal clad leaf, or run a high traffic entrance, and you want a bearing hinge instead: from what we carry, the Orca Hardware 3535 Series is a 4-1/2 x 4-1/2 square corner ball bearing commercial hinge, and the Don-Jo HWBB74545 is a heavy weight full mortise ball bearing hinge in the same 4-1/2 x 4-1/2 size.

No, the pin is removable. On an outswing exterior door where the barrel is on the outside, that means someone can drive the pin and lift the door, so specify an NRP hinge for those openings. The Hager BB1168 NRP is a non-removable pin full mortise ball bearing hinge and is the option to look at when the door swings out into a public area.

The Orca Hardware 4014 Series is the nearest match on size and corner style: it is a 4 inch by 4 inch plain bearing commercial hinge with 1/4 inch radius corners, the same 4 inch by 4 inch dimension, 1/4 inch radius corner style and plain bearing type the Deltana SS44R4 carries. The difference that matters is material - the SS44R4 is stainless steel throughout, which is why it is specified for waterside and outdoor openings, while the Orca 4014 is a steel commercial hinge. On an interior opening where corrosion is not a factor, the two drop into the same 4 inch by 4 inch mortise with the same radius router prep.

No - the SS44R4 is a mechanical full mortise hinge with no wire path through the barrel. Power transfer requires an electrified hinge: the Command Access ETH-BB68 is a 5 knuckle heavy duty steel base energy transfer hinge, the ETH-CB70 is a 3 knuckle standard weight steel base energy transfer hinge, and the BEST CECB179-12C is a steel full mortise concealed bearing electrified hinge with a 12-wire quick connect. If you also need door position monitoring back to the panel, the Command Access ETM-BB68 adds an integrated door position switch. One electrified hinge per opening is typical; the remaining hinges in the opening can be standard mortise hinges.

For a 3-1/2 inch prep with radius corners, the Orca Hardware 3514 Series is the direct step down: a 3.5 inch by 3.5 inch 1/4 inch radius corner plain bearing commercial hinge, matching the SS44R4 on 1/4 inch radius corner style and plain bearing type at the smaller leaf size. If the existing prep is square corner at 3-1/2 inch, the Emtek 91013 is a 3-1/2 inch by 3-1/2 inch plain bearing hinge pair with square corners in plated steel, and the Schlage Residential S3P1010 is a 3.5 inch by 3.5 inch square corner plain bearing mortise hinge supplied in packs of three.

They are both 4 inch by 4 inch pairs, but they are prepped differently and built for different service. The Delaney RH45xx is a 4 inch by 4 inch bulk residential exterior hinge with 5/8 inch radius corners - that 5/8 inch radius will not seat in a mortise routed for the 1/4 inch radius the SS44R4 uses, and vice versa. The SS44R4 is a commercial stainless steel hinge. If the frame prep is 5/8 inch radius, the Delaney RH45xx or the RH40xx, a 4 inch by 4 inch residential hinge pair in 5/8 inch radius by square, is the correct family; if the prep is 1/4 inch radius, it is not a substitute.

The SS44R4 is not supplied with a non-removable pin. For an out-swinging exterior door where the barrel is accessible from the unsecured side, the Hager BB1168 is a non-removable pin full mortise ball bearing heavy duty hinge and is the direct answer to that requirement. For detention and high-security openings the BEST BB855 heavy-duty steel double weight concealed ball bearing prison hinge and the Hager 990 STEEL full surface prison hinge at 3 inch by 4 inch with a welded tip go further, though those are full surface or double weight builds rather than a standard 4 inch by 4 inch full mortise replacement.

Yes, #9 x 1 inch wood screws are supplied, which are sized for a solid wood door and wood frame. On a hollow metal frame or a door with a metal edge you will need machine screws instead, since a 1 inch wood screw has nothing to bite into there.

Commercial. It is a full mortise commercial hinge rather than a residential builder's hinge, which is the difference between this and something like the Emtek 91013, a residential plain bearing 3-1/2 x 3-1/2 pair, or the Delaney 4 x 4 bulk exterior residential hinges. Where the SS44R4 earns its place on a commercial opening is the stainless base metal, not extra duty rating.

The SS44R4 uses a plain bearing, which is the standard arrangement for typical commercial door traffic. On high-cycle or heavier door leaves, buyers move to a bearing hinge: 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 at 4-1/2 inch by 4-1/2 inch in satin chrome. Note that both of those step away from the 4 inch by 4 inch stainless construction of the SS44R4 - if the opening is exterior or near salt air, the stainless base of the SS44R4 is the property that is doing the work there.

The SS44R4 is built at 4 inch by 4 inch and does not cover a 4-1/2 inch prep. At 4-1/2 inch by 4-1/2 inch, the Orca Hardware 3535 Series is a square corner ball bearing commercial hinge, the Don-Jo HWBB74545 is a heavy weight full mortise ball bearing hinge in satin chrome, and the Stanley FBB191 is a 5 knuckle full mortise standard weight hinge at 4.5 inch by 4.5 inch. For a wider leaf on a thicker door, the Don-Jo HWBB75045 is a heavy weight full mortise ball bearing hinge at 5 inch by 4-1/2 inch in steel with a satin chrome finish. Confirm corner style against the frame before you pick among them.

The SS44R4 is a full mortise hinge, meaning both leaves mortise in - one into the door edge, one into the frame rebate. Where the frame takes a surface-applied leaf instead, the Hager 1129 is a half mortise plain bearing commercial hinge at 4-1/2 inch in standard weight steel, and the Hager 990 STEEL is a full surface prison hinge at 3 inch by 4 inch with a welded tip. Mounting method has to match the existing prep on both the door and the frame; it is the first thing to confirm, before size or corner style.

No. The SS44R4 is a commercial hinge in stainless steel at 4 inch by 4 inch with 1/4 inch radius corners. The Ives 1010RP is a steel plain bearing residential hinge with square corners sold as a set of three, and the Emtek 91013 is a residential duty plain bearing hinge pair at 3-1/2 inch by 3-1/2 inch with square corners in plated steel. They share the plain bearing arrangement, but they differ on size, corner style and base material, and they ship in different counts - the SS44R4 is sold by the pair. If you are standardizing a building on one hinge, those differences are what to hold constant.

The SS44R4 is a plain bearing hinge with a conventional knuckle barrel. If you want the bearing out of sight, the Hager 920 is a full mortise concealed plain bearing hinge with 2 knuckle steel construction, and the Ives 3CB1 is a 3 knuckle concealed bearing full mortise hinge in medium duty commercial grade. Both are full mortise like the SS44R4, so the mounting method carries over; verify leaf size and corner style against the existing prep since those are what govern the swap.
