Deltana S44R5BMS 4" x 4" x 5/8" Radius Hinge, Bench Mark, Security, Steel (Pair)

The S44R5BMS gets its security from a stud and lock tab, not from the pin. Deltana lists the option as Sec/Loc. Tab, which is an interlocking stud on one leaf that seats into a hole in the other when the door is closed, so the leaves can't be pried apart even if someone gets at the pin. The pin itself is a standard removable pin, not an NRP. If your spec calls specifically for a non-removable pin set screw rather than a security stud, this isn't the one; the Hager BB1168 is a full mortise ball bearing hinge built with a non-removable pin.

It will if your current hinge is also 4 x 4 with 5/8 inch radius corners. That's the most common radius on residential and light commercial steel hinges cut by a router template. Measure the corner of the existing mortise: if it's square, you'd be filling and recutting, and a square corner 4 x 4 like the Orca COM4040 matches that prep instead. A 1/4 inch radius prep is a third profile again, and the Orca COM4014 is the 4 x 4 hinge cut for it. Radius mismatch is the usual reason a replacement hinge won't sit flush.

Plain bearing is what the S44R5BMS uses, and Deltana positions the steel line for indoor applications. That's fine for interior doors on normal residential and light commercial traffic: bedroom, office, unit interior doors, closets. Where it falls short is a heavy door, a door with a closer on it, or a high-cycle opening like a stairwell or corridor, because the friction the bearing would take goes straight into the knuckles. For those, move to a bearing hinge such as the Orca 3535 Series 4-1/2 x 4-1/2 ball bearing commercial hinge or the Ives 3CB1HW heavy weight concealed bearing full mortise hinge.

Keep it inside. Deltana calls the steel hinge line a value choice for indoor applications, and plated steel on an exterior opening is where corrosion shows up first at the knuckles. For an exterior residential door in a 4 x 4 with the same 5/8 inch radius, the Delaney RH45 series is built for exterior use. For a genuine security or detention opening, a security stud hinge is the wrong tool entirely; that's what the BEST BB855 heavy duty concealed ball bearing prison hinge and the Hager 990 full surface prison hinge with welded tip are for.

Not without recutting. A 4 x 4 leaf is half an inch taller and half an inch wider than a 3-1/2 x 3-1/2, so it won't sit in the smaller mortise and the screw holes won't line up. Stay at 3-1/2 x 3-1/2 to swap straight across: the Delaney RH35 series is a 3-1/2 x 3-1/2 steel interior hinge with the same 5/8 inch radius corner, so the mortise profile matches. If your smaller mortise has square corners instead, the Emtek 91013 is a 3-1/2 x 3-1/2 plain bearing plated steel pair with square corners.

No. The Deltana S44R5BMS is a plain bearing steel hinge with a security tab and no conductor path through the barrel. For an opening that has to carry power to an electric strike, latch retraction, or a card reader in the door, the transfer has to come from a purpose-built hinge: the Command Access ETH-CB70 is an energy transfer hinge on a 3 knuckle standard weight steel base, and the ETH-BB68 is the 5 knuckle heavy duty version. If the opening also has to report door position back to the panel, the Command Access ETM-CB70 adds door position sensing on the same 3 knuckle steel base.

The Deltana S44R5BMS is a 4 inch by 4 inch full mortise steel hinge with 5/8 inch radius corners and plain bearings, sold as a pair. The closest match in another brand is the Orca Hardware 4014 Series, a 4 inch by 4 inch radius corner plain bearing commercial hinge, though Orca cuts a 1/4 inch radius rather than 5/8 inch. If the door and jamb are prepped square instead, the Orca 4040 Series is a 4 inch by 4 inch square corner plain bearing commercial hinge. Corner radius has to match the existing mortise, so confirm the prep before swapping between the two.

The Deltana S44R5BMS carries a security or locking tab and is listed with a removable pin, so the stud interlocks the leaves but the pin itself is not fixed. On an outswing opening where the barrel is exposed, the Hager BB1168 is a non-removable pin full mortise ball bearing heavy duty hinge, which pins the fastener in place rather than relying on the interlock alone. It is a heavy duty ball bearing hinge, so it is a different weight class than the plain bearing S44R5BMS and expects a heavier leaf.

No. The Deltana S44R5BMS is a full mortise hinge, which means both the door edge and the jamb have to be prepped to receive a leaf. Where only one side is mortised, the mounting style has to change: the Hager 1129 is a half mortise plain bearing commercial hinge in 4-1/2 inch standard weight steel, and the Hager 990 is a full surface hinge that faces onto the door and frame at 3 inch by 4 inch. Match the mounting style to the prep you already have rather than cutting a second mortise.

The Deltana S44R5BMS is cut with 5/8 inch radius corners at 4 inch by 4 inch, so it will not seat cleanly in a square mortise. For square prep at the same 4 inch leaf, the Orca 4040 Series is a square corner plain bearing commercial hinge in 4 inch by 4 inch, and the Delaney CH401X is a 4 inch by 4 inch commercial ball bearing hinge with square corners. Both hold the leaf size; the Delaney steps to ball bearing.

Screws are included: #9 x 1 inch wood screws, sized for wood jambs and wood door edges. That length is short enough to stay in the jamb material on a residential frame. If you're hanging into a hollow metal frame or want the leaf anchored back into the stud on a heavier door, you'll want to source machine screws or longer screws separately, since what ships is the wood screw.

The S44R5BMS is sold by the pair, two hinges per unit of measure. A standard interior door normally hangs on three hinges, so a single door takes two pairs and leaves you a spare leaf pair, or you order in bulk. Deltana packs these 50 pairs to a case at 40 lbs, which is the number to quote from if you're doing a multi-unit turn or a whole floor of a building.

No. It's a full mortise butt hinge with a symmetrical pair of leaves, so the same hinge hangs a left hand or right hand door; you just flip it. Handing only becomes an ordering decision on hinges with a directional feature built in, like the Stanley CECB1900R54L electrified hinge, which is specified left-handed because the wire exit has to be on the correct side.

The leaf gauge is 0.085 inch steel, both leaf and substrate being steel throughout. That thickness puts it in standard weight territory rather than heavy weight, which lines up with where Deltana aims it: interior doors of ordinary weight. On a solid core slab hung with a closer, or a heavy exterior door, you'd step up to a heavy weight hinge like the Don-Jo HWBB74545 in 4-1/2 x 4-1/2.

The Deltana S44R5BMS is 4 inch by 4 inch with 5/8 inch radius corners and is rated commercial. For residential openings cut to the same 5/8 inch radius, Delaney offers the RH45 series, a 4 inch by 4 inch bulk residential exterior hinge with 5/8 inch radius, and the RH35 series in 3-1/2 inch by 3-1/2 inch for interior residential doors. The 3-1/2 inch size will not fill a 4 inch mortise, so measure the existing leaf before ordering down.

It does not. The security or locking tab on the Deltana S44R5BMS interlocks the two leaves so the door cannot be lifted off if the pin is pulled, on a plain bearing steel hinge sized 4 inch by 4 inch. That is a different category from detention hardware: the BEST BB855 is a heavy duty steel double weight concealed ball bearing prison hinge in the detention hardware series, the Hager 990 is a full surface prison hinge at 3 inch by 4 inch with a welded tip, and the Stanley BB855 is a double weight prison hinge at 5 inch by 6 inch furnished with no holes and not swaged. Correctional and behavioral health openings are specified from that group, not from a security stud hinge.

Both are plain bearing steel hinges sold as a pair. The Deltana S44R5BMS is 4 inch by 4 inch with 5/8 inch radius corners and a security tab, rated commercial. The Emtek 92013 is a heavy duty plain bearing hinge at 3-1/2 inch by 3-1/2 inch with square corners in plated steel; Emtek also lists the 91013 in the same 3-1/2 inch square corner plain bearing form under its residential duty line. The two differ on leaf size and corner cut, so they are not interchangeable in an existing mortise.

The Deltana S44R5BMS is a 4 inch by 4 inch steel hinge. Where the leaf needs to grow, the 4-1/2 inch options in steel are the Don-Jo HWBB74545 and HWBB84545, both heavy weight full mortise ball bearing hinges at 4-1/2 inch by 4-1/2 inch in satin chrome, and the Stanley FBB191, a 5-knuckle full mortise standard weight hinge at 4.5 inch by 4.5 inch. For a wider throw again, the Don-Jo HWBB75045 is a 5 inch by 4-1/2 inch heavy weight full mortise ball bearing hinge in steel. Going from 4 inch to 4-1/2 inch means recutting the mortise, so plan it on new prep rather than a swap.

Two: Brushed Brass and Prime Coat White. Prime Coat White is the one to pick when the hinge is getting painted to match the door or trim, which is the usual move on a paint-grade interior door in a rental or spec build. Brushed Brass is the finished option if the hinge is staying visible against brass or bronze lever hardware.

They are both full mortise steel hinges but they are built differently. The Deltana S44R5BMS is a plain bearing hinge in 4 inch by 4 inch with 5/8 inch radius corners and a security tab. The Ives 3CB1 is a 3-knuckle concealed bearing full mortise hinge rated medium duty, so the bearing is carried inside the knuckle rather than riding on plain surfaces, and the knuckle count differs from a standard 5-knuckle profile. If the visible barrel has to match the other doors in the run, the knuckle pattern is the thing to check first.
