Orca Hardware CXD4545BB 4-1/2" x 4-1/2" Square Corner Ball Bearing Extra Heavy Weight Hinge

The Orca CXD4545BB is a 4-1/2 by 4-1/2 inch full mortise hinge with square corners, so it drops into a standard square-corner 4-1/2 inch mortise pocket with no radius. If the existing pockets on your frame and door are radius-cut (typically 5/8 inch radius from a factory-machined hollow metal frame), a square corner hinge will leave gaps at the corners and you want a radius corner hinge instead.

Yes. The CXD4545BB carries an extra heavy duty rating and runs on ball bearings, which is what you want on a heavy or high-cycle opening such as a main entry, stairwell, or a solid core door with a closer on it. Ball bearings carry the door weight without the knuckle wear you get from a plain bearing hinge, which is fine on a light interior door but not on a door that swings all day.

It does. The CXD4545BB is supplied with the non-removable pin option in brushed chrome. That matters on an outswing exterior or a door where the hinge barrel is on the unsecure side, because an NRP set screw stops someone driving the pin out and lifting the door off.

The Hager BB1168 is the nearest match: it is a full mortise ball bearing hinge supplied with a non-removable pin, the same two defining traits as the Orca CXD4545BB, which is a full mortise ball bearing hinge offered with a non-removable pin. The difference is duty level - the Hager BB1168 is rated Heavy Duty, while the Orca CXD4545BB carries an Extra Heavy Duty rating for commercial openings.

Use an electrified hinge. The Command Access ETH-BB68 is a 5-knuckle heavy duty steel base energy transfer hinge, the BEST CECB179-12C is a steel full mortise concealed bearing electrified hinge with a 12-wire quick connect, and the Stanley CECB1900R54L is a 3-knuckle concealed bearing concealed conductor hinge in 4-1/2 by 4-1/2 square corner, left-handed, 4-wire. The Orca CXD4545BB is a mechanical ball bearing hinge with no wire transfer, so it cannot carry power to the lock.

Yes. The Stanley Security FBB191 is a 5-knuckle full mortise hinge in the same 4-1/2 inch by 4-1/2 inch size, built as a standard weight hinge, and the Stanley 2060R is a full mortise square corner hinge in that same 4-1/2 by 4-1/2 size with spring action. Both drop into the same square corner prep as the Orca CXD4545BB, which is a 4-1/2 inch by 4-1/2 inch square corner hinge rated Extra Heavy Duty for higher traffic doors.

The Deltana CSB45N is a 4-1/2 inch by 4-1/2 inch square hinge sold in pairs with a non-removable pin, matching the Orca CXD4545BB on size, square corners and the NRP feature. The Deltana DE44R5TA is a security hinge in 4 inch by 4 inch with a 5/8 inch radius corner and tamper-resistant construction, which needs a radius corner prep rather than the square prep the Orca uses.

The Delaney CH401X is a 4 inch by 4 inch commercial ball bearing hinge with square corners, so it matches the Orca CXD4545BB on bearing type, corner style and commercial intent while fitting a 4 inch mortise. The Orca CXD4545BB is 4-1/2 inch by 4-1/2 inch and will not drop into a 4 inch prep without recutting.

No. Both wood and machine screws ship with the hinge, so it covers a wood door and frame or a hollow metal frame with tapped hinge holes. Nothing else is required to hang the leaf.

Only if the opening is genuinely residential. The Orca CXD4545BB is specified for commercial application with an Extra Heavy Duty ball bearing rating. Lighter square corner options include the Emtek 94013 heavy duty ball bearing hinges in 3-1/2 by 3-1/2 plated steel, the Emtek 91013 residential plain bearing hinges in the same 3-1/2 by 3-1/2 square corner size, and the Schlage Residential S3P1010 3.5 by 3.5 square corner plain bearing mortise hinges sold three to a pack. All three are smaller than 4-1/2 by 4-1/2, so the door and frame mortise must be cut for the smaller leaf.

Not from the Orca 4545 Series, which is a mechanical ball bearing full mortise hinge. For monitoring, the Command Access ETM-BB68 is an energy transfer monitor hinge with an integrated door position switch on a heavy duty base, and the ETM-CB70 is a 3-knuckle steel base version with door position sensing at a medium duty rating.

No. 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. Concealed bearing places the bearings inside the knuckle rather than as visible ball bearing races. The Orca CXD4545BB is a ball bearing hinge with square corners, rated Extra Heavy Duty, so the barrel appearance and the bearing arrangement differ even though both are full mortise.

Detention openings take a purpose-built hinge. 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 inch by 6 inch, and the Hager 990 STEEL is a full surface prison hinge 3 inch by 4 inch with a welded tip. The Orca CXD4545BB is an Extra Heavy Duty commercial full mortise hinge in 4-1/2 by 4-1/2, built for standard commercial traffic rather than detention prep.

They are different bearing types. Plain bearing options include the Hager 1129 half mortise standard weight steel hinge in 4-1/2 inch and the Ives 1010RP steel plain bearing residential hinge with square corners sold in sets of three at a medium duty rating. The Orca CXD4545BB uses ball bearings and carries an Extra Heavy Duty rating, which is what high-cycle commercial openings and heavy door leaves are specified with; plain bearing suits lighter, lower-cycle doors.

They share the size but not the build. The McKinney SQ3331 is a square barrel 2-knuckle decorative hinge at 4-1/2 inch by 4-1/2 inch with a Standard Duty rating, intended where appearance drives the selection. The Orca CXD4545BB is a full mortise ball bearing hinge in the same 4-1/2 by 4-1/2 size carrying an Extra Heavy Duty commercial rating, so on a heavy or high-traffic leaf the two are not interchangeable.

No. The Orca CXD4545BB is a full mortise ball bearing hinge for a single-direction swing. For a double acting interior opening, the BEST DAP-3 is a heavy duty double acting pivot made for commercial interior doors and is the correct hardware type for that swing.

It comes in brushed chrome. If your other openings are running satin chrome or brushed nickel trim, brushed chrome reads closely; against bright brass or oil rubbed bronze it will not match, so standardize the whole opening before you order a run.
