Hager RC1842-3.5X3.5-26D – Frequently Asked Questions

1) Is the Hager RC1842 hinge right for a commercial door, or is it residential only?
The RC1842 is a residential hinge. Hager classifies it as residential, medium duty, and it conforms to the Light Weight requirements of ANSI A156.1 under certification ANSI A5134. That covers entry, passage, bedroom, bath and closet doors in houses and apartment units. For a high traffic commercial opening, a stairwell, or anything on a closer, step up to a ball bearing or concealed bearing commercial hinge such as the Don-Jo BB74545 or the BEST 1900R.
2) Will a 5/8 inch radius round corner hinge drop into my existing door mortise?
Only if the existing mortise is routed with round corners at a 5/8 inch radius. The RC1842 has a 5/8 inch radius corner, which is the corner most factory prepped residential wood doors and machine routed jambs use. If the pocket in your door has square corners, this hinge leaves a gap at each corner and you would want a square corner hinge instead, like the Don-Jo BB74545 or the McKinney TCA2314. Pull one existing hinge and look at the corner of the cutout before you order.
3) Should I order the 3-1/2 x 3-1/2 or the 4 x 4 Hager RC1842?
Both sizes are offered. Match the size of what is coming off the door: 3-1/2 x 3-1/2 is the usual size for 1-3/8 inch interior doors (bedroom, bath, closet), and 4 x 4 is what you normally find on 1-3/4 inch entry and exterior doors. Every one of the 12 finishes is offered in both sizes, so switching size does not cost you a finish.
4) Do I have to order a left hand and a right hand version of this Hager hinge?
No. The RC1842 is reversible, so one hinge works on a left or right hand door. Handing is not something you specify when ordering, which also means a property manager can stock one part number for every door in the building regardless of swing.
5) Can I pull the pin on the RC1842 to take a door off its hinges?
Depends which pin type you order. The RC1842 comes with either a removable pin or a non removable pin. Removable pin lets you drive the pin out and lift the door off for painting, moving furniture, or replacing the slab without touching the frame screws. Non removable pin is what you want on an outswing exterior door where the barrel is exposed on the outside, since the pin cannot be driven out from the street side.
6) Plain bearing or ball bearing hinge, which one do I need?
Plain bearing, like the RC1842, has no bearings between the knuckles and is meant for lighter doors that get ordinary household use. Ball bearing and concealed bearing hinges carry the load on bearing races and hold up under heavier doors, door closers, and constant traffic. If the door is a heavy solid core slab, has a closer on it, or is an apartment corridor or commercial entry, go ball bearing: the Don-Jo BB74545 or the McKinney TCA2314. For a heavy weight opening the McKinney TCA3386 is the heavy duty option.
7) What is the closest equivalent to a Hager RC1842 hinge for a commercial opening that needs a bearing hinge?
The RC1842 is a plain bearing residential hinge in steel with a 5/8 inch radius round corner, rated medium duty. For a commercial opening where a bearing hinge is called for, the BEST 1900R is a steel full mortise concealed bearing standard weight hinge with a removable pin, also medium duty, and the Stanley Security CB1960R is a full mortise concealed bearing standard weight hinge from the Architectural Hinges series. Both carry the bearing construction in the same full mortise footprint, while the RC1842 uses a plain bearing.
8) Does the Hager RC1842 come with screws, or do I need to buy fasteners separately?
Screws are in the box. Each hinge ships with wood screws sized 3/4 inch x 9 flat head, so a standard wood door and wood jamb needs nothing else. Into a hollow metal frame those wood screws are no good, and you would need machine screws to suit the frame's tapped holes.
9) How many Hager RC1842 hinges do I need to order for one door, and how are they packed?
Order by the piece or by the box: the RC1842 sells as a single hinge or as a box of 2. A standard residential door takes 3 hinges, so a single door is either 3 singles or a box of 2 plus a single. On a run of doors, a 20 door job is 60 hinges, or 30 boxes.
10) What finishes does the Hager RC1842 hinge come in, and can I match the rest of my door hardware?
Twelve finishes: 1D flat black, 2D zinc dichromate, 600 primed for painting, 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. The 600 primed option is the one to take when the hinge has to be painted to match trim. For coordinating with locks and levers, 626 satin chrome and 619 satin nickel are the two that pair with most residential lockset lines.
11) Why do my new Hager residential hinges squeak, and do they need oiling?
They ship dry. Hager supplies its residential hinges without lubrication and recommends lubricating them after installation. Do it before you hang the door, while the pin is still out, on a plain bearing hinge like the RC1842 the knuckles run steel on steel and that is where the noise comes from.
12) Is the Hager RC1842 a full mortise hinge, and what prep does the door need?
Full mortise. Both leaves get recessed, one into the door edge and one into the jamb, so the hinge sits flush and the leaves close on each other. That means routed pockets in both the door and the frame, cut to the hinge size you order and with 5/8 inch radius corners. If your door and frame have no mortise pockets at all, you are cutting new prep, not swapping a hinge.
13) Can I run electrified hinges on the same doors as the Hager RC1842 for an access control retrofit?
Not with the RC1842 itself. It's a plain bearing steel residential hinge with no wire path through it. Power transfer at the hinge needs a concealed electric through wire hinge, and ZenSupply carries the ACSI 5BB1, a 5 knuckle ball bearing full mortise hinge in 4-1/2 x 4-1/2 with a concealed 4 wire 28 gauge through wire. Typical practice is one electrified hinge per door carrying the power, with standard hinges in the other positions.
14) Is a Don-Jo BB74545 a drop-in substitute for a Hager RC1842?
Not on the same opening. The BB74545 is a 4-1/2 by 4-1/2 inch square corner ball bearing hinge, while the RC1842 is offered in 3-1/2 by 3-1/2 inch and 4 by 4 inch with a 5/8 inch radius round corner and a plain bearing. The mortise size and the corner cut both differ, so the frame prep has to match the hinge you order. Where the RC1842 does fit, the Don-Jo BB84545 is the brass version of that same 4-1/2 by 4-1/2 square corner pattern and the BB94545 is stainless steel, both square corner as well.
15) The doors are beveled edge, not square edge. Does that change which hinge I order against a Hager RC1842?
It can. Several full mortise hinges are cut specifically for one edge condition: the BEST CB248 concealed bearing swing clear hinge is specified for square edge doors, while the BEST CB223 stainless steel concealed bearing heavy weight pivot reinforced hinge is specified for beveled edge doors. The RC1842 is a plain bearing residential hinge with a 5/8 inch radius round corner, so match the corner cut of the frame prep first and then the door edge condition when you move to a bearing hinge.
16) I have a satin chrome finish standard across the building. Which comparable hinges come in it?
The RC1842 is offered in 626 satin chrome along with 625 bright chrome, 619 satin nickel, 605 bright brass and other finishes. Among the comparables, the Don-Jo BB74540 is a full mortise ball bearing hinge, 4-1/2 by 4 inch, in satin chrome, and the Don-Jo BB84545 is a brass full mortise ball bearing hinge, 4-1/2 by 4-1/2 inch, also in satin chrome. Those two are the larger square-prep sizes, so use them where the opening will not take the RC1842's 5/8 inch radius corner.
