Hager RC1843 4X4 US26 – Frequently Asked Questions

1) Do I need to order left hand and right hand versions of the Hager RC1843?
No. The RC1843 is reversible, so the same hinge hangs a left hand or right hand door. The pin is removable, so you set the door by pulling the pin rather than by ordering a handed part. For a property manager stocking spares across a building, that means one part number covers every swing.
2) What does the safety stud on this Hager hinge actually do for security?
The RC1843 carries a security stud: a projecting pin on one leaf that engages a matching hole in the opposite leaf when the door is closed. If someone pulls the hinge pin on an out-swinging door, the stud keeps the leaves interlocked and the door stays in the frame. That is the reason to spec this one over a plain residential hinge on an exterior out-swing entry.
3) Is a plain bearing hinge like the RC1843 good enough for a commercial opening?
No. The RC1843 is a residential hinge with a plain bearing, meaning the knuckles ride metal on metal rather than on a bearing race. That is fine for interior passage, bedroom, bath and closet doors and for residential entries in multi-family units. For a high-traffic commercial opening or a heavy door with a closer, move to a bearing hinge: the Don-Jo BB74545 is a 4-1/2 x 4-1/2 steel ball bearing full mortise hinge, and the BEST 1900R is a steel full mortise concealed bearing hinge with a removable pin.
4) Can I mix the RC1843 with 4-1/2 inch hinges on the same door?
No. The RC1843 is a 4 x 4 hinge and the mortise depth and screw pattern differ from a 4-1/2 inch hinge, so all leaves on one door need to be the same size. If your existing openings are prepped 4-1/2 x 4-1/2, go to a hinge cut for that size such as the McKinney TCA2314 or the Don-Jo BB74545, and note those are square corner, not radius.
5) Can I use the Hager RC1843 on a commercial corridor or fire rated opening?
The RC1843 is specified as a residential hinge with a plain bearing and ANSI A8134 certification, which suits entry, passage, bedroom, bath and closet doors including multi-family units. For commercial architectural openings, the comparable set includes purpose-built options: the BEST 1900R steel full mortise concealed bearing standard weight hinge with removable pin and the Stanley Security CB1960R concealed bearing standard weight hinge, both medium duty in the Architectural Hinges series, and the Dormakaba CB199 full mortise concealed bearing heavy weight hinge for the heaviest leaves. Verify the hinge selected carries the listings your opening requires.
6) What finishes does the Hager RC1843 4 x 4 hinge come in?
Eight finishes, all on the 4 x 4 size: 605 bright brass, 606 satin brass, 609 antique brass, 619 satin nickel, 620 antique nickel, 625 bright chrome, 626 satin chrome, and US10R dark bronze. If you're matching existing lever sets and door hardware across a building, 626 satin chrome and 619 satin nickel are the two that pair with the most common modern trim.
7) Is the Hager RC1843 steel or brass, and does that matter for an exterior door?
Steel leaves with a steel pin. Steel is the right call for painted or plated interior and protected entry doors. On a coastal or heavily weather-exposed opening, a brass or stainless hinge holds up better against corrosion, for example the Don-Jo BB84545 in brass or the BB94545 in stainless steel, both 4-1/2 x 4-1/2 ball bearing.
8) How many hinges do I get when I order the Hager RC1843, and are screws included?
It's boxed one pair, two hinges, with mounting screws in the box. A standard residential door takes three hinges, so a single door needs two boxes and you'll have one spare hinge. Case quantity on the 4 inch size is 50 each for anyone buying by the carton.
9) What gauge and knuckle count is the Hager RC1843, and what weight of door will it carry?
Five knuckles, 0.085 gauge steel. That is standard residential weight, sized for hollow core and typical solid core interior doors and standard residential entry slabs. A heavy solid wood or metal door, or any leaf running a door closer, calls for a heavy weight hinge instead, such as the McKinney TCA3386 or the Dormakaba CB199 concealed bearing heavy weight.
10) Can the Hager RC1843 be used for an access control door with power transfer through the hinge?
No. The RC1843 is a plain bearing residential hinge with a removable pin and no wire path through the barrel. For power to an electric strike or electrified lock, you need a through-wire hinge, for example the ACSI 5BB1 four wire concealed electric through-wire hinge in 4-1/2 x 4-1/2.
11) What hinge do I use instead of the Hager RC1843 on a heavy or oversized door?
The RC1843 is a plain bearing residential hinge and is not the part for a heavy leaf. For heavy weight service, the McKinney TCA3386 is a square corner 5 knuckle full mortise hinge, 4-1/2 inch by 4-1/2 inch, rated heavy duty; the Dormakaba CB199 is a full mortise concealed bearing heavy weight hinge in the Architectural Hinges series; and the BEST FBB212 is a steel ball bearing pivot reinforced hinge for square edge doors. Pivot reinforced designs like the FBB212 and the stainless BEST CB223 add support where the door weight or width is beyond a standard leaf.
12) I need power transfer through the hinge - does the Hager RC1843 support that?
The RC1843 is a mechanical hinge with a removable pin and safety stud; it carries no wiring. For an electrified opening where power has to reach a lock or monitored device in the door, the ACSI 5BB1 is a 5 knuckle ball bearing full mortise hinge, 4-1/2 inch by 4-1/2 inch, with concealed electric through-wire in a 4 wire 28 gauge configuration. Spec the wire count against what the door device actually needs before ordering.
13) I want a brass hinge to match brass trim - is the Hager RC1843 solid brass?
No. The RC1843 is steel with a steel pin, offered in plated finishes that include 605 bright brass, 606 satin brass and 609 antique brass. If the specification calls for a solid brass base material rather than a brass finish, the Don-Jo BB84545 is a full mortise ball bearing hinge in brass, 4-1/2 inch by 4-1/2 inch, standard duty. It is a larger leaf than the 4 inch by 4 inch RC1843, so the door and frame prep has to suit.
14) What is the difference between the Hager RC1843 and a concealed bearing hinge like the BEST 1900R?
The RC1843 uses a plain bearing, where the knuckles bear directly on one another and rely on lubrication for smooth swing; it is a 5-knuckle residential hinge with a removable pin, safety stud and 5/8 inch radius corners. The BEST 1900R is a steel full mortise hinge with a concealed bearing, also with a removable pin, rated medium duty in the Architectural Hinges series - the bearings sit inside the knuckle so the barrel reads as a plain hinge while carrying more cycles. The Stanley Security CB1960R is the same general approach, a concealed bearing standard weight full mortise hinge at medium duty.
15) Is the Don-Jo BB74540 a direct replacement for the Hager RC1843?
No. The BB74540 is a full mortise ball bearing hinge in a 4-1/2 inch by 4 inch size, finished in satin chrome, rated standard duty - the leaf height differs from the RC1843's 4 inch by 4 inch, so it will not sit in the same mortise. If satin chrome is what you are matching, the RC1843 is offered in 626 satin chrome at 4 inch by 4 inch, which keeps the existing prep.
16) My door is beveled on the edge - can I still use the Hager RC1843?
Confirm the prep before ordering. Several hinges in the category are called out by door edge. The BEST CB223 is a stainless steel concealed bearing heavy weight pivot reinforced hinge specifically for beveled edge doors, while the BEST FBB212 steel ball bearing pivot reinforced hinge and the BEST CB248 swing clear hinge are both specified for square edge doors. Match the hinge to the edge detail of your leaf and to the 5/8 inch radius or square corner of the existing mortise.
