Hager RCBB1842 3-1/2X3-1/2 US3 – Frequently Asked Questions

1) Will the Hager RCBB1842 hinge work on a commercial office door?
No. The RCBB1842 is a residential-duty ball bearing hinge, certified to ANSI A8134. For a commercial opening with real traffic, go to a standard or heavy weight architectural hinge instead, like the McKinney TCA2314 (standard duty) or the McKinney TCA3386 heavy weight, both 4-1/2 by 4-1/2 inch. Apartment interior doors, closets, and bedroom doors in multi-family are where the RCBB1842 belongs.
2) What sizes does the Hager RCBB1842 ball bearing hinge come in?
Two: 3-1/2 x 3-1/2 inch and 4 x 4 inch, and every finish is offered in both. The 3-1/2 inch is the usual choice for 1-3/8 inch interior doors, the 4 inch for heavier or 1-3/4 inch doors. If your existing hinges are 4-1/2 x 4-1/2, this is not the replacement.
3) Do I need to order a left hand and right hand version of the RCBB1842?
No handing to specify. The hinge is reversible with a removable pin, so the same part goes on a left hand or right hand door. Order by size and finish only.
4) Can I use the Hager RCBB1842 to run power to an electrified lock in the door?
The RCBB1842 is a mechanical ball bearing hinge with a removable pin and no wire path through the barrel. To carry power from frame to door, the ACSI 5BB1 is a five knuckle ball bearing full mortise hinge at 4-1/2 by 4-1/2 with a concealed electric through-wire, four wire in 28 gauge, from the 1100 Series. Transfer hinges like that one replace a single hinge in the stack, so the remaining leaves in the opening can stay as they are as long as the sizes match.
5) What is the closest equivalent to the Hager RCBB1842 hinge if I need a square corner instead of a radius corner?
The Hager RCBB1842 is a five knuckle full mortise ball bearing hinge with 5/8 inch radius round corners, made in 3-1/2 by 3-1/2 and 4 by 4 sizes. When the door and frame are prepped with square corner mortises instead, the Don-Jo BB74545 is a steel square corner five knuckle full mortise ball bearing hinge in 4-1/2 by 4-1/2, standard duty. The McKinney TCA2314 is another square corner five knuckle full mortise hinge at 4-1/2 by 4-1/2. Corner style has to match the existing mortise or the frame gets rerouted, so confirm the corner radius on the door already hung before ordering.
6) My existing hinges measure 4-1/2 by 4 inches. Is the Hager RCBB1842 a drop-in replacement?
No. The RCBB1842 is made in 3-1/2 by 3-1/2 and 4 by 4, so a 4-1/2 by 4 mortise leaves the leaf undersized in both directions. The Don-Jo BB74540 is a full mortise ball bearing hinge at 4-1/2 by 4 inches in satin chrome, standard duty, which matches that mortise directly. Hinge width and height both have to match the existing cutout, since a narrower leaf changes how far the door stands off the frame as well as leaving open rout.
7) How many hinges come in a box of Hager RCBB1842?
Boxed in pairs, two hinges per box, with mounting screws included. A standard 6 foot 8 inch door takes three hinges, so plan two boxes per door and you will have one spare hinge.
8) What finishes does the Hager RCBB1842 hinge come in, and can I match the rest of my building?
Nine finishes, all available in both sizes: 605 bright brass, 606 satin brass, 609 antique brass, 619 satin nickel, 620 antique nickel, 625 bright chrome, 626 satin chrome, US10A antique bronze, and US10R dark bronze. For a property standardizing a fleet of units, 626 satin chrome and 619 satin nickel are the two that match most modern lever trim.
9) Is a ball bearing hinge worth it over a plain bearing hinge on an apartment door?
On a door that gets cycled hard, yes. The RCBB1842 runs a ball bearing between its five knuckles, so the door swings without the knuckle-on-knuckle wear that makes a plain bearing hinge squeak and sag. On a closet door that opens twice a week it is overkill. On unit entry doors, doors with a closer, or anything carrying a solid core slab, the bearing is what keeps the door hanging true.
10) Is the Hager RCBB1842 steel or stainless, and will it hold up in a damp location?
Steel with a steel pin, finished in plated finishes. That is fine for interior doors and protected entries. For a coastal or wash-down opening where corrosion is the concern, move to a stainless hinge such as the Don-Jo BB94545, or a brass body like the Don-Jo BB84545.
11) What is the difference between the Hager RCBB1842 and a concealed bearing hinge like the BEST 1900R?
The Hager RCBB1842 is a ball bearing hinge with five knuckles, so the bearings sit in visible races between the knuckles. The BEST 1900R is a steel full mortise concealed bearing standard weight hinge with a removable pin, medium duty, from the Architectural Hinges series, and the Stanley Security CB1960R is the same concealed bearing standard weight full mortise arrangement in that series. Concealed bearing hinges hide the bearing inside the barrel for an unbroken knuckle profile. Both types are removable pin, so the RCBB1842 and either concealed bearing hinge come off the frame the same way.
12) Is a pivot reinforced hinge the same thing as the Hager RCBB1842 ball bearing hinge?
No, though both can be ball bearing. The RCBB1842 is a standard five knuckle full mortise ball bearing hinge for residential openings. The BEST FBB212 is a steel ball bearing heavy weight pivot reinforced hinge for square edge doors, standard duty, and the BEST CB223 is the concealed bearing version of that arrangement in stainless steel for beveled edge doors. Pivot reinforced hinges add a reinforcing element at the bearing point for heavier leaves, so they are not a like-for-like swap into a mortise cut for a plain full mortise hinge.
13) What ball bearing hinge should I use on an exterior or wet-area door instead of the Hager RCBB1842?
The RCBB1842 is built from steel with a steel pin and offered in finishes including 626 satin chrome and 605 bright brass. Where the opening sees weather or washdown, the Don-Jo BB94545 is a stainless steel full mortise ball bearing hinge at 4-1/2 by 4-1/2 with square corners, standard duty, and the Don-Jo BB84545 is the same 4-1/2 by 4-1/2 full mortise ball bearing hinge in brass with a satin chrome finish. Both change the base metal rather than the hinge type, so the door still swings on a standard full mortise mortise.
14) What is the difference between the Hager RCBB1842 and the McKinney TCA2314 or TCA2317?
All three are five knuckle full mortise hinges. The RCBB1842 is a ball bearing hinge with 5/8 inch radius round corners in 3-1/2 by 3-1/2 and 4 by 4, reversible with a removable pin. The McKinney TCA2314 and TCA2317 are both square corner five knuckle full mortise hinges at 4-1/2 by 4-1/2 in standard duty. The two McKinney numbers differ from each other by base metal and finish rather than by size or corner style, so a distributor pulling stock should quote the exact TCA number the job calls out.
15) My doors have beveled edges. Does that rule out the Hager RCBB1842?
Edge profile matters when the hinge is cut for one or the other. The BEST CB223 is a stainless steel concealed bearing heavy weight pivot reinforced hinge specified for beveled edge doors, while the BEST CB248 swing clear and the BEST FBB212 ball bearing heavy weight pivot reinforced hinge are both specified for square edge doors. Confirm the leaf edge on the doors being hung and match the hinge that names that edge, then check the mortise size and corner style before you order.
16) Can I take the door off without unscrewing the hinges?
Yes. The RCBB1842 has a removable pin, so you drive the pin out and lift the leaf apart with the hinge plates still screwed to the door and frame. Useful for moving appliances or refinishing a slab without re-mortising anything.
