Deltana S45BBN 4-1/2" x 4-1/2" Square Hinge, Heavy-Duty, NRP, Ball Bearings, Steel

If the door and jamb are already cut for a 4-1/2 x 4-1/2 hinge with square corners, yes. The S45BBN measures 4-1/2 x 4-1/2 with square corners and is a full mortise hinge, so it sits in the same pocket. What it will not do is drop into a mortise with rounded corners, which is the common factory-machined cut on many prehung doors. Check the corner of your existing pocket first: radius corners need a radius hinge, not this one.

NRP means non-removable pin. A set screw in the barrel seats against the pin once the door is closed, so the pin cannot be tapped out from the hinge side. That matters on any outswing door, where the knuckles are exposed on the exterior and pulling the pin would otherwise let someone lift the door out of the frame. On an inswing door the hinges are inside and NRP buys you nothing, so save it for the outswing openings.

The Hager BB1168 NRP is the commercial answer: full mortise, ball bearing, heavy duty, with the non-removable pin. The Deltana S45BBN gives you the same NRP and ball bearing combination in a residential-class steel hinge, which is the right call on an apartment or house entry but not on a heavily used commercial opening.

Not in the same mortise. The S45BBN is 4-1/2 x 4-1/2, so it will not sit in a pocket cut for a 3-1/2 inch hinge without recutting the door edge and the jamb. To match a building already running 3-1/2 inch square corner hinges, use a 3-1/2 x 3-1/2 square corner hinge instead, such as the Emtek 94013 heavy duty ball bearing pair or the Schlage Residential S3P1010 square corner set. Where the doors are already 4 inch, the Delaney CH401X is a 4 x 4 square corner ball bearing hinge.

The Deltana S45BBN is designated for residential use, so for a commercial opening the Orca Hardware 3535 Series is the direct dimensional swap - a 4-1/2 by 4-1/2 square corner ball bearing commercial hinge at a medium duty level. The Don-Jo HWBB84545 covers the same 4-1/2 by 4-1/2 size as a heavy weight full mortise ball bearing hinge in satin chrome for higher-traffic commercial doors. All three share the ball bearing knuckle and the square corner prep, so mortises cut for one accept the others.

The Hager BB1168 is the nearest match on function: it is a full mortise ball bearing hinge, heavy duty, with a non-removable pin, the same combination the Deltana S45BBN carries in 4-1/2 by 4-1/2 with square corners and a steel body. The difference a buyer feels is finish selection - the Deltana S45BBN runs across eight decorative finishes including Oil Rubbed Bronze, Polished Brass, and Prime Coat White, so it is the one that has to match existing trim on an outswing door where NRP is required for security.

Corner style is not interchangeable - the Deltana S45BBN has square corners and will leave gaps in a rounded pocket. For 1/4 inch radius corners, the Orca Hardware 4014 Series is a 4 by 4 plain bearing commercial hinge and the 3514 Series is a 3-1/2 by 3-1/2 plain bearing commercial hinge, both medium duty. In residential 5/8 inch radius, the Delaney exterior hinge pair comes in 4 by 4 and the Delaney interior hinge pair in 3-1/2 by 3-1/2. Confirm the radius against the existing pocket before ordering, since 1/4 inch and 5/8 inch are different preps.

Only if the opening needs power through the hinge, and then the Deltana is not the right part at all. The Command Access ETH-BB68 is an energy transfer hinge, 5 knuckle heavy duty steel base, and the Stanley CECB1900R54L is a three knuckle concealed bearing concealed conductor hinge, 4-1/2 by 4-1/2 square corner, left-handed, 4-wire. Those carry current to an electrified lock or exit device. The Deltana S45BBN is a mechanical hinge with a non-removable pin and no conductor path, so it goes in the non-powered positions of the same opening while the electrified hinge takes the powered position.

Both screw types ship with the hinge: #12 x 1-1/4 inch wood screws for the door and jamb, and #12 x 1/2 inch machine screws for a metal frame. Nothing else is required to hang the door. On a hollow metal frame, confirm the jamb is tapped for #12 machine screws before you set the hinge.

The leaf is .134 inch thick. Route the mortise to that depth so the leaf sits flush with the door edge and jamb face. Go deeper and the door binds against the stop; leave it shallow and the door will not close square against the jamb.

The S45BBN is sold as a pair. A standard door up to about 7 feet takes three hinges, so plan on two pairs per opening and a spare leaf, or order in multiples that get you to three per door. Two hinges is enough only on a light interior slab.

Eight finishes: Polished Brass, Antique Brass, Oil Rubbed Bronze, Brushed Nickel, Antique Nickel, Polished Chrome, Brushed Chrome, and Prime Coat White. The Prime Coat White is the one to order when the hinge is getting painted to match the door or trim, so you are not stripping a plated finish to get paint to stick.

Ball bearing, which is what the S45BBN uses. The bearings carry the door weight between knuckles instead of letting steel grind on steel, so a heavy slab swings without the squeak and the sag that a plain bearing hinge develops under load. Plain bearing is fine on a light hollow-core interior door: the Emtek 92013 and the Orca 4040 Series are plain bearing options. If you want the bearing hidden inside the barrel for a cleaner look, that is a concealed bearing hinge, like the Ives 3CB1.

No. The Deltana S45BBN is a full mortise ball bearing hinge with a non-removable pin and no closing mechanism - it pivots freely and the door stays where it is put. For self-closing without a surface closer, the Stanley 2060R is a full mortise spring hinge in square corner 4-1/2 by 4-1/2 at a heavy duty level, which drops into the same square corner prep and leaf size. Buyers often run spring hinges in one or two positions and standard ball bearing hinges in the rest.

Bearing placement and appearance. The Deltana S45BBN uses visible ball bearings between the knuckles and carries a non-removable pin, in 4-1/2 by 4-1/2 square corner steel across eight decorative finishes. The Ives 3CB1HW is a steel heavy weight concealed bearing full mortise hinge with 3 knuckles, and the Ives 3CB1 is the medium duty concealed bearing version of the same full mortise pattern. Concealed bearing hides the bearing inside the knuckle for a smoother barrel line, which is why it shows up on architectural commercial specs; the exposed ball bearing barrel on the Deltana is the traditional look on residential trim.

Step up to a 5 inch leaf. The Don-Jo HWBB75045 is a heavy weight full mortise ball bearing hinge in 5 by 4-1/2 steel with a satin chrome finish, and the Don-Jo HWBB85045 is the brass-body heavy weight full mortise ball bearing hinge in the same 5 by 4-1/2 size. Both are heavy duty and keep the ball bearing knuckle the Deltana S45BBN uses, but the taller leaf means a new mortise - a frame cut for the 4-1/2 by 4-1/2 Deltana will not take a 5 inch hinge without recutting.

It is the same leaf size but a different hinge. The McKinney SQ3331 is a square barrel 2-knuckle decorative hinge in 4-1/2 by 4-1/2 at a standard duty level, so it is chosen for the barrel appearance. The Deltana S45BBN in the same 4-1/2 by 4-1/2 is a ball bearing hinge with a non-removable pin, which is what an outswing exterior door needs so the pin cannot be driven out from the exposed side. If security on an outswing opening is the requirement, the NRP feature is the deciding spec.

The detention and full surface hinges. The BEST BB855 is a heavy-duty steel double weight concealed ball bearing prison hinge, the Stanley BB855 is a double weight prison hinge furnished with no holes and not swaged in 5 by 6, and the Hager 990 STEEL is a full surface prison hinge 3 by 4 with a welded tip. Full surface mounts to the face of the door and frame rather than into a mortise, and an unswaged, unbored leaf has to be drilled to suit. The Deltana S45BBN is a full mortise hinge in 4-1/2 by 4-1/2, prepped and ready for a standard mortise pocket.

The Stanley FBB191 is a 5-knuckle full mortise standard weight hinge in 4.5 by 4.5 at a heavy duty level, and the McKinney MPB79 MacPro is a 5-knuckle standard weight hinge - both are architectural lines chosen when a facility standardizes on one commercial pattern across every opening. The Deltana S45BBN is a residential-designated full mortise ball bearing hinge in the same 4-1/2 by 4-1/2 square corner size, and its eight finishes including Antique Brass, Polished Chrome, and Antique Nickel make it the choice where the hinge has to match decorative trim rather than a commercial finish schedule.

The Hager 1129 is a half mortise plain bearing commercial hinge in 4-1/2, standard weight steel and heavy duty, which mortises into the door but screws to the face of the frame - the option when the frame cannot be routed. For a door that has to swing both directions, the BEST DAP-3 is a heavy duty double acting pivot for commercial interior doors, which carries the leaf on the floor and head instead of the jamb. The Deltana S45BBN is a full mortise hinge and needs a pocket cut in both the door edge and the jamb.

No. The S45BBN is a symmetrical full mortise butt hinge with square corners, so the same hinge works on a left-hand or right-hand door. You just flip it. Handing does become a factor with hinges that carry wiring or a spring, such as the Stanley CECB1900R54L, which is ordered left-handed.

Yes. Ball bearings are what makes that work: a closer cycles the door constantly, and plain bearing knuckles wear and start to squeal under that duty. If the opening is a commercial door on a closer running all day, step up to a heavy duty commercial hinge such as the Ives 3CB1HW heavy weight concealed bearing or the Don-Jo HWBB74545 in the same 4-1/2 x 4-1/2 size.
