Deltana S44U4-R – Frequently Asked Questions
1) Will a Deltana S44-R square corner hinge drop into an existing hinge mortise?
Only if the existing mortise is square cut and 4 x 4. The S44-R has square corners, so it will not sit in a pocket routed for a radius corner hinge without filling or squaring the corners. Most factory prehung residential doors are machined with a 5/8 inch radius, which is why radius corner hinges like the Delaney RH45xx 4 x 4 exterior residential hinge exist. Pull one of the old hinges and look at the corner before you order.
2) Can I use the Deltana S44-R on an exterior entry door for security?
Not where security matters. The S44-R does not have a non-removable pin, so with the door closed on an out-swing opening the hinge pin sits on the exposed side and can be driven out. On in-swing doors, where the barrel is inside, that is a non-issue and this hinge is fine. For an out-swing exterior or a secured opening, use an NRP hinge such as the Hager BB1168 NRP full mortise ball bearing hinge.
3) I have 3-1/2 inch hinges on my doors now, can I use the Deltana S44-R instead?
Not without recutting. The S44-R is 4 x 4, so a 3-1/2 inch mortise is a half inch short in both directions and the screw holes will not line up. Either stay at 3-1/2 inches with something like the Emtek 91013 residential plain bearing square corner hinge or the Schlage Residential S3P1010, or route the mortises out to 4 inches. Hinge size normally tracks door weight and thickness, so do not shrink to 3-1/2 on a heavy slab just to avoid the router.
4) What is the closest 4 inch square corner steel hinge to the Deltana S44-R if I need a commercial ball bearing version instead?
The Deltana S44-R is a 4 inch by 4 inch square corner steel hinge with a plain bearing, sold as a pair for residential use. If the opening needs a bearing hinge in the same size and corner style, the Delaney CH401X is a 4 inch by 4 inch commercial ball bearing hinge with square corners, and the Orca Hardware 3535 Series is a 4-1/2 inch by 4-1/2 inch square corner ball bearing commercial hinge rated medium duty. The Orca requires a larger mortise, so it is a match only if the door and frame are prepped for 4-1/2 inch leaves.
5) The Deltana S44-R is residential thickness. What holds up better on a high traffic door?
The S44-R is a .085 thickness steel hinge for residential interior use. Where the door sees heavier or more frequent cycling, the Emtek 92013 is a heavy duty plain bearing hinge in 3-1/2 inch by 3-1/2 inch with square corners in plated steel, and the Emtek 94013 is a heavy duty ball bearing hinge in the same 3-1/2 inch square corner size. For 4-1/2 inch by 4-1/2 inch openings, the Don-Jo HWBB84545 is a heavy weight full mortise ball bearing hinge in satin chrome. All three change the leaf size or the bearing type, so check the mortise and the frame prep before swapping.
6) My doors are prepped with a 5/8 inch radius corner. Is there a residential 4 inch hinge that fits instead of the square corner Deltana S44-R?
The S44-R has square corners, so it needs a square corner mortise. For a 4 inch by 4 inch radius prep, the Delaney RH40xx is a 4 inch by 4 inch residential hinge with a 5/8 inch radius by square configuration, and the Delaney RH35xx is a 3-1/2 inch by 3-1/2 inch bulk residential interior hinge with a 5/8 inch radius, both sold as pairs. Match the corner radius to what is already routed into the door before ordering.
7) I want the hinge to hold the door closed on its own. Will the Deltana S44-R do that?
No. The S44-R is a standard full mortise plain bearing hinge with no closing mechanism. For a self-closing opening, the Stanley Security 2060R is a full mortise spring hinge with square corners in 4.5 inch by 4.5 inch on a ferrous steel base, rated heavy duty. It is a different leaf size and needs a 4-1/2 inch mortise, so it is a spec change rather than a drop-in.
8) I need a hinge with a non-removable pin for a door that swings out. Is the Deltana S44-R an option?
The S44-R is not supplied with a non-removable pin. For an outswinging door where the pin needs to be secured, the Hager BB1168 is a non-removable pin full mortise ball bearing hinge rated heavy duty. It is a heavy duty commercial hinge rather than a residential thickness steel hinge, so confirm the mortise size and door prep against what is currently in the frame.
9) How many Deltana S44-R hinges do I need for one door?
The S44-R is sold by the pair, so a standard interior door hung on three hinges takes two pairs, and you will have one spare leaf set left over. Three hinges is the normal count for a 6 foot 8 inch door; two hinges is only used on light closet or cabinet-style doors. For a 7 foot or taller door plan on four hinges, which is two pairs exactly.
10) Is the Deltana S44-R a full mortise hinge that needs to be routed into the door and jamb?
Yes, it is a full mortise hinge, so both leaves get mortised, one into the door edge and one into the jamb, and the barrel sits proud between them. It is not a surface mounted or half mortise hinge. Screw holes are on an arc pattern, which is the standard staggered layout that keeps the fasteners off a single grain line in a wood jamb.
11) How thick is the leaf on the Deltana S44-R hinge?
Leaf thickness is .085 inch, which is residential gauge. That matters for the mortise depth: the pocket has to be cut so the leaf sits flush with the door edge, and swapping a .085 leaf into a mortise cut for a heavier commercial hinge will leave the leaf low and the door hard to shim square. Steel throughout, both leaves and base material.
12) What finishes does the Deltana S44 Series 4 inch square hinge come in?
Ten finishes, so you can match nearly any lever or knob already in the building: Oil Rubbed Bronze, Polished Nickel, Brushed Nickel, Antique Nickel, Paint Black, Polished Chrome, Brushed Chrome, Polished Brass, Brushed Brass, and Antique Brass. If you are standardizing a unit turnover or a whole floor of apartments, that spread lets you keep one hinge model across doors with different trim packages.
13) Should I buy a plain bearing or a ball bearing hinge for an interior door?
Plain bearing, like the Deltana S44-R, is the right call for interior residential doors with no closer, where the door is light and cycles a few times a day. Ball bearing costs more and buys you smooth operation under weight and constant use, which is what a door closer or a solid core commercial slab demands. If the opening has a closer on it, go ball bearing, for example the Delaney CH401X commercial ball bearing hinge in the same 4 x 4 square corner size.
14) Do I need to order a left hand or right hand version of the Deltana S44-R hinge?
No handing to specify. The S44-R is a symmetrical full mortise butt hinge, so the same pair hangs a left or right hand door, and both leaves are drilled the same. Electrified and monitor hinges are where handing bites you, for example the Stanley CECB1900R54L is a left-handed hinge. A plain butt hinge like this one is not handed.
15) Which hinges look like a substitute for the Deltana S44-R but are not?
Several hinges in the same size range serve a different purpose entirely. The Command Access ETH-CB70 is an energy transfer hinge with a 3-knuckle standard weight steel base, built to run wire through the door for electrified hardware, and the Command Access ETM-CB70 adds door position sensing on top of that. The BEST CECB179-12C is a steel full mortise concealed bearing electrified hinge with a 12-wire quick connect. The Hager 1129 is a half mortise hinge, which mounts differently from the full mortise S44-R. None of these substitute for a plain mechanical residential hinge on an ordinary interior door.
16) I need a smaller residential square corner hinge than the 4 inch Deltana S44-R. What are my options?
The Deltana S44-R is 4 inch by 4 inch. For a 3-1/2 inch by 3-1/2 inch square corner residential plain bearing hinge sold as a pair, the Emtek 91013 is plated steel with square corners in the Residential Duty Hinges series. The Schlage Residential S3P1010 is a 3.5 inch by 3.5 inch square corner plain bearing mortise hinge sold in packs of three, which suits a three-hinge door in one order. Hinge size has to match the existing mortise, so confirm the leaf size cut into the door before dropping from 4 inch to 3-1/2 inch.
17) Do I need a ball bearing hinge, or is the plain bearing Deltana S44-R enough?
The S44-R uses a plain bearing, which is the common choice for residential interior doors. Peers split the same way: the Ives 1010RP is a steel plain bearing residential hinge with square corners sold as a set of three, while the Ives 3CB1 is a 3-knuckle concealed bearing full mortise hinge rated medium duty and the Ives 3CB1HW is a heavy weight concealed bearing full mortise hinge with 3 knuckles. Bearing hinges are the pick when door weight or cycle count is the deciding factor; plain bearing suits lighter interior doors.
18) What is the difference between the Deltana S44-R and a 5-knuckle standard weight commercial hinge?
The S44-R is a 4 inch by 4 inch residential thickness steel hinge with a plain bearing and square corners, sold by the pair. The McKinney MP79 MacPro is a 5-knuckle standard weight full mortise hinge, and the Stanley FBB191 is a 5-knuckle full mortise standard weight hinge in 4.5 inch by 4.5 inch. Those are architectural hinges sized for commercial frames; the S44-R is sized and specified for residential interior doors.
19) I am standardizing hinges across a building and want one decorative option with a square barrel. What is comparable to the Deltana S44-R?
The S44-R covers finish variety on a square corner residential hinge, offered in oil rubbed bronze, polished nickel, brushed nickel, antique nickel, paint black, polished chrome, brushed chrome, polished brass, brushed brass, and antique brass. If the look calls for a square barrel instead of a standard barrel, the McKinney SQ3331 is a square barrel 2-knuckle decorative hinge in 4-1/2 inch by 4-1/2 inch, rated standard duty. The larger leaf size means a different mortise, so it standardizes only if the doors are prepped for 4-1/2 inch.
