Hager RC1846 4X4 US4 – Frequently Asked Questions

1) Will the Hager RC1846 4" x 4" hinge fit my existing door mortise with rounded corners?
The RC1846 is a 4 x 4 full mortise hinge with 5/8 inch (16 mm) radius round corners, so it drops into a pocket routed by a standard hinge router template. If the existing mortises on your doors are square cut, this leaf will sit with a gap at each corner. Check one door before you order a case: 5/8 radius and square corner are the two common corner styles, and they are not interchangeable without rework.
2) Do I need to order left hand and right hand versions of the Hager RC1846 hinge?
No. The RC1846 is reversible, so one part number covers both left and right hand doors. Order the quantity you need and stock a single SKU across the building instead of splitting your order by handing.
3) Is the Hager RC1846 hinge heavy enough for a commercial entry or a high-traffic door?
No, and this is the one to get right. The RC1846 is a plain bearing residential hinge conforming to ANSI A156.1 Light Weight, which means interior residential leaves, not a commercial opening with a closer on it. For a door that gets worked hard, move to a ball bearing or concealed bearing hinge: the Don-Jo BB74545 is a standard duty ball bearing full mortise hinge, and the McKinney TCA3386 is a heavy weight option. Plain bearing knuckles wear under closer pressure and constant traffic; bearings are what carry that load.
4) Can the pin be pulled out of a Hager RC1846 hinge from the outside of the door?
The RC1846 has a riveted security pin, so the pin is not intended to be driven out in service. That rules out the simplest way of lifting a door off its hinges, but it also means you cannot pull the pin to take a door down for painting or moving furniture. If you want doors that can be dropped off the frame quickly, specify a removable pin hinge instead, such as the BEST 1900R with a removable pin.
5) Is the Hager RC1846 a direct swap for the 4" x 4" hinges already on my apartment doors?
If what is coming off is a 4 x 4 residential hinge with 5/8 radius corners, yes, the RC1846 lines up on the same mortise and the same screw pattern is the standard residential layout. Two things to confirm on the old hinge first: corner style, since a square corner mortise will not close up around a radiused leaf, and size, since 4-1/2 x 4-1/2 is the other common size and is a different cut entirely. The RC1846 is 4 x 4 only.
6) I need a hinge that clears the door opening for wheelchair access. Will the Hager RC1846 do that?
No. The RC1846 is a standard full mortise hinge, so the door leaf remains in the opening when it is swung back and eats into the clear width. A swing clear hinge is the part that solves this: the BEST CB248 is a steel full mortise concealed bearing swing clear hinge for square edge doors, medium duty, from the Swing Clear Hinges series. It swings the leaf fully out of the opening to recover the door thickness as usable width.
7) Can the Hager RC1846 carry power through the door for an electric strike or maglock?
No. The RC1846 is a plain bearing hinge with a riveted security pin and no wire path through the barrel. For power transfer at the hinge, the ACSI 5BB1 is a 5 knuckle ball bearing full mortise hinge at 4-1/2 inch by 4-1/2 inch with concealed electric through-wire, 4 wire at 28 gauge, from the 1100 Series. That is the part to specify when the door carries an electrified lock, exit device, or contact.
8) What is the closest ball bearing alternative to the Hager RC1846 for a residential door that gets heavy daily traffic?
The RC1846 is a plain bearing hinge built to residential duty, which suits interior doors that open a few times a day. Where a door sees constant use, a ball bearing hinge carries the leaf better under repeated cycling. The Don-Jo BB74545 is a full mortise ball bearing hinge in steel with a square corner and 5 knuckles at 4-1/2 inch by 4-1/2 inch, rated standard duty. Note the size change: the RC1846 is 4 inch by 4 inch, so the BB74545 needs a wider mortise in both door and frame and cannot drop into an existing 4 inch prep.
9) The Hager RC1846 has 5/8 inch round corners. What hinge do I use if my door and frame are prepped with square corners?
Corner style has to match the routed pocket. The RC1846 carries a 5/8 inch radius corner, which fits the rounded pocket a hinge router leaves in a wood door. A frame mortised with square corners wants a square corner hinge instead. The McKinney TCA2314 is a square corner 5 knuckle full mortise hinge at 4-1/2 inch by 4-1/2 inch in standard duty, and the Don-Jo BB94545 is a square corner full mortise ball bearing hinge in stainless steel at the same 4-1/2 inch by 4-1/2 inch size.
10) Can I use the Hager RC1846 on a heavy commercial entrance door?
The RC1846 is a residential plain bearing hinge conforming to ANSI A156.1 Light Weight, which puts it on interior residential leaves rather than heavy commercial openings. For a heavy door, use a heavy weight hinge: the McKinney TCA3386 is a heavy weight square corner 5 knuckle full mortise hinge at 4-1/2 inch by 4-1/2 inch, the Stanley Security CB199 is a heavy weight full mortise concealed bearing hinge, and the BEST CB223 is a heavy weight stainless steel concealed bearing pivot reinforced hinge for beveled edge doors.
11) What finishes does the Hager RC1846 4" x 4" hinge come in?
Four finishes to choose from: 2D zinc dichromate, 626 satin chrome, 605 bright brass, and 606 satin brass. All four are the 4 x 4 size. For a property manager matching existing openings, 626 satin chrome reads as the brushed silver most modern units carry and 606 satin brass matches brushed gold trim; 2D zinc dichromate is a plain utility coating usually used where the hinge will not be seen.
12) How many hinges do I need per door with the Hager RC1846?
Three per door is the normal count for a standard interior residential door up to about 7 feet, one at the top, one at the bottom, and one centered between. The RC1846 ships 2 each per box on non-bulk orders, so a three-hinge door does not come out of a single box cleanly. For a job doing multiple units, bulk is packed 100 each in the 4 inch size, which is where the numbers work out better for a whole building.
13) Does the Hager RC1846 hinge meet ANSI standards for a spec job?
The RC1846 carries ANSI A8134 certification and conforms to ANSI A156.1 Light Weight. That is a residential grade designation. If the drawing calls for a commercial architectural hinge, the RC1846 will not satisfy it; the Stanley Security CB1960R and the BEST 1900R are architectural series concealed bearing hinges, and the Dormakaba CB199 is a heavy weight architectural option.
14) What is the difference between the Hager RC1846 plain bearing hinge and a concealed bearing hinge like the BEST 1900R?
The RC1846 runs plain bearing, meaning the knuckles bear directly on one another with no bearing element, and it has a riveted security pin that stays in the barrel. The BEST 1900R is a steel full mortise concealed bearing standard weight hinge in medium duty with a removable pin, so the bearings sit hidden inside the knuckle and the pin can be pulled to take the door off without unscrewing the leaves. The Stanley Security CB1960R is the same idea, a full mortise concealed bearing standard weight hinge in medium duty. Pick by whether you want the pin captive or removable, and by how much cycling the leaf will see.
15) The Hager RC1846 is steel. What is the equivalent in brass or stainless for a door in a wet or coastal location?
The RC1846 is steel with a steel pin and comes in finishes including 2D zinc dichromate, 605 bright brass, 606 satin brass, and 626 satin chrome. Where the base material itself needs to resist corrosion rather than relying on a plated finish, the Don-Jo BB94545 is a full mortise ball bearing hinge in stainless steel, square corner, 4-1/2 inch by 4-1/2 inch, and the Don-Jo BB84545 is the same size in brass finished satin chrome. Both are standard duty, and both are a size step up from the 4 inch by 4 inch RC1846.
16) For standardizing hinges across an apartment portfolio, how does the Hager RC1846 compare to the McKinney TCA2314 and TCA2317?
The RC1846 is the residential specification: plain bearing, 5 knuckles, 4 inch by 4 inch, 5/8 inch radius corners, riveted security pin, ANSI A8134 certified and conforming to ANSI A156.1 Light Weight, and reversible so one part number covers left and right hand doors. The McKinney TCA2314 and TCA2317 are both square corner 5 knuckle full mortise hinges at 4-1/2 inch by 4-1/2 inch in standard duty. Standardizing on the RC1846 holds unit interior doors to one 4 inch prep and one reversible part; standardizing on the McKinney pair means a 4-1/2 inch square corner prep throughout.
17) Do Hager RC1846 hinges come with screws, or do I need to buy them separately?
Mounting screws are included with the RC1846, so nothing else is needed to hang a door on a properly prepped frame. Worth noting for wood jambs on exterior or heavier openings: the supplied wood screws bite the jamb only, so many installers replace one screw per leaf in the frame with a long screw run into the stud.
18) How thick is the steel on the Hager RC1846 hinge?
The leaf gauge is 0.085 and the hinge is steel with a steel pin, in a 5 knuckle configuration. That gauge is the residential light weight range, not the thicker material used on commercial hinges, which is consistent with it conforming to ANSI A156.1 Light Weight. If your spec calls out a heavier gauge or a stainless leaf, look at a stainless option such as the Don-Jo BB94545 instead.
19) Is a pivot reinforced hinge like the BEST FBB212 a substitute for the Hager RC1846?
They are not interchangeable. The RC1846 is a residential plain bearing full mortise hinge, 4 inch by 4 inch, with 5/8 inch radius corners. The BEST FBB212 is a steel ball bearing heavy weight pivot reinforced hinge for square edge doors in standard duty; pivot reinforced means the top hinge location is built to take the load a pivot would normally carry, which belongs on heavy commercial leaves, not a residential interior door. Swapping one in changes the prep, the corner profile, and the weight class of the opening.
