Hager RC1741-3.5X3.5-26D – Frequently Asked Questions

1) Is the Hager RC1741 hinge right for a commercial door, or is it a residential hinge?
The RC1741 is a residential hinge, medium duty, and Hager notes its residential hinges conform to the Light Weight requirements of ANSI A156.1. Use it on interior passage, bedroom, bath, closet and residential entry doors, including apartment units. For a commercial opening with closers, heavy traffic, or a solid core fire door, step up to a ball or concealed bearing architectural hinge such as the BEST 1900R standard weight or, for heavy weight service, the McKinney TCA3386.
2) Will a round corner hinge fit my door if the existing mortise has square corners?
No. The RC1741 has 1/4 inch radius round corners, so it drops into a router-cut mortise with rounded corners, which is what a hinge template or a hand router leaves. If the pocket in your door and frame has sharp square corners, that prep was chiseled or factory cut for a square corner hinge, and a round corner hinge will leave gaps at the corners. Pull the old hinge and look at the pocket before ordering. For square corner prep, a square corner hinge like the Don-Jo BB74545 or McKinney TCA2314 matches.
3) What size Hager RC1741 hinge do I need, 3-1/2 inch or 4 inch?
The RC1741 is ordered in 3-1/2 x 3-1/2 inch and 4 x 4 inch. The 3-1/2 inch is the common size for hollow core and light interior doors; the 4 inch is what most solid core interior and residential entry doors take. Easiest check is to measure the hinge already in the door, height and open width, and match it, since the mortise is cut to that size.
4) Do I have to order a left hand and right hand version of the RC1741?
No handing to specify. The RC1741 is reversible, so the same hinge goes on a left hand or right hand door. That is one part number to stock across a building instead of two.
5) Can I take the door off without unscrewing the hinges?
Only if you order the removable pin version. The RC1741 is offered with 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 swapping the slab. Non removable pin is the one to specify on an out swinging exterior door where the hinge barrel is on the outside, since a loose pin there is a security hole.
6) Can the Hager RC1741 be used to run power to an electrified lock in the door?
No - the RC1741 is a plain bearing full mortise hinge with a removable or non-removable steel pin and no wire path through the knuckle. For a powered door, the ACSI 5BB1 is a 5 knuckle ball bearing full mortise hinge at 4-1/2 inch by 4-1/2 inch with a concealed electric through-wire, 4 wire in 28 gauge, from the 1100 Series. On a typical opening one electrified hinge carries the transfer and the remaining hinges are standard, so an RC1741 can still be used in the other positions where the size and corner prep match.
7) What is the closest equivalent to the Hager RC1741 if the door is already mortised for square corners?
The RC1741 is cut with 1/4 inch radius corners, so it drops into a router-cut mortise but leaves a gap in a chisel-cut square pocket. For a square-corner mortise, the Don-Jo BB74545 is a full mortise steel hinge with square corners and the same 5-knuckle configuration, in 4-1/2 inch by 4-1/2 inch. McKinney also builds the TCA2314 as a square corner 5-knuckle full mortise hinge at 4-1/2 inch by 4-1/2 inch. Both differ from the RC1741 in bearing type: the Don-Jo BB74545 is ball bearing where the RC1741 runs a plain bearing.
8) The RC1741 is a residential hinge - what should be used on a high traffic commercial opening instead?
The RC1741 is specified for residential use at a medium duty level, which suits dwelling entry and interior doors. For heavier commercial cycles, the McKinney TCA3386 is a heavy weight square corner 5 knuckle full mortise hinge at 4-1/2 inch by 4-1/2 inch, and the Stanley Security CB199 is a full mortise concealed bearing heavy weight hinge in the Architectural Hinges series. Both are rated heavy duty, against the RC1741's medium duty residential rating.
9) Which hinge should be used instead of the RC1741 when the doorway needs the full clear opening width for wheelchair access?
The RC1741 is a standard full mortise hinge, so the open door leaf still sits in the opening. Where the leaf has to clear the opening, the BEST CB248 is a steel full mortise concealed bearing swing clear hinge for square edge doors, in the Swing Clear Hinges series and rated medium duty, the same duty level the RC1741 carries. Note the CB248 is prepped for square edge doors, so confirm the door edge before ordering.
10) Are screws included with the Hager RC1741, or do I need to buy fasteners?
Wood screws come in the box. Hager packs the RC1741 two hinges per box with screws, flat head wood screws sized for the hinge. Nothing else to order for a wood jamb. If you are hanging into a hollow metal frame you will need machine screws instead, since the supplied fasteners are wood screws.
11) How many RC1741 hinges do I need per door, and can I buy singles?
Both a single piece and a box of two are orderable. Most interior residential doors take three hinges, and heavier or taller slabs take four, so a box of two plus a single covers a typical three hinge door. Buying singles is also how you match one odd opening without a leftover.
12) My RC1741 hinges are squeaking right out of the box, is that normal?
Yes, and it is expected. Hager ships its residential hinges without lubrication, and recommends lubricating after installation. These are plain bearing hinges, metal knuckle on metal knuckle with no bearing race, so a little grease or a dry lube on the pin at hang time is part of the install. If you want a hinge that runs quiet without that step, a bearing hinge such as the BEST 1900R concealed bearing is the alternative.
13) Can I get RC1741 hinges to match the brass and bronze hardware already in my building?
Twelve finishes are offered on the RC1741: flat black (1D), zinc dichromate (2D), primed for painting (600), bright brass (605), satin brass (606), antique brass (609), satin nickel (619), antique nickel (620), bright chrome (625), satin chrome (626), antique bronze (US10A) and dark bronze (US10R). For a fleet of doors, match the BHMA number on your existing lever or lockset rather than the finish name, since names vary between brands and the number does not. The 600 primed option is there when the hinge gets painted with the door.
14) Does the Hager RC1741 carry an ANSI certification?
The RC1741 is certified to ANSI A5134, and Hager states its residential hinges meet the Light Weight requirements of ANSI A156.1. That is the residential grade side of the hinge standard. If your spec calls for a Grade 1 or Grade 2 A156.1 architectural hinge, this is not that hinge, and you want a bearing hinge from an architectural series instead.
15) What is the difference between the Hager RC1741 plain bearing hinge and a concealed bearing hinge like the BEST 1900R?
Both carry a medium duty rating, but the bearing arrangement differs. The RC1741 runs a plain bearing with 5 knuckles in steel. The BEST 1900R is a steel full mortise concealed bearing standard weight hinge with a removable pin, in the Architectural Hinges series; Stanley Security builds the CB1960R to the same description, a full mortise concealed bearing standard weight hinge, also medium duty. Concealed bearing hinges hide the bearing inside the knuckle rather than showing a bearing race between knuckles. The RC1741 is offered with removable and non-removable pins, so a removable pin is available either way.
16) The RC1741 is steel - what hinge should be used on an exterior or damp opening where steel would corrode?
The RC1741 is built from steel with a steel pin and is offered in finishes including 1D flat black, 2D zinc dichromate, 626 satin chrome and US10R dark bronze. Where the base material itself needs to resist corrosion rather than the coating, the Don-Jo BB94545 is a full mortise ball bearing hinge in stainless steel with square corners at 4-1/2 inch by 4-1/2 inch, and the BEST CB223 is a stainless steel concealed bearing hinge. Both are square corner or pivot reinforced designs rather than the 1/4 inch radius corner the RC1741 uses, so the door prep differs.
17) What is the difference between the Don-Jo BB84545 and the Hager RC1741 for matching existing brass hardware?
The RC1741 is a steel hinge finished in a range that includes 605 bright brass, 606 satin brass and 609 antique brass, so the brass appearance comes from the finish over a steel base. The Don-Jo BB84545 is a full mortise ball bearing hinge built in brass at 4-1/2 inch by 4-1/2 inch and supplied in satin chrome. If the requirement is a solid brass hinge body, that is the BB84545; if the requirement is a brass appearance on a 3-1/2 inch or 4 inch round corner prep, the RC1741 covers it.
18) What gauge is the Hager RC1741 and what is it made of?
Steel leaves at .085 inch gauge with a steel pin, and the pin is .234 inch diameter. Standard weight, so it is dimensionally interchangeable with other standard weight residential hinges of the same leaf size and radius, but it is not a heavy weight hinge. Steel means it wants a painted or plated finish for any damp location; for a coastal or wet opening, a stainless or brass hinge like the Don-Jo BB94545 stainless or BB84545 brass is the better material.
19) Where do the hinges go on the door, what is the standard layout?
Hager publishes a standard hinge locations sheet covering where the top, bottom and intermediate hinges land on the door and frame, and it is the reference to use when cutting new prep for the RC1741 rather than following an existing pocket. On a replacement job you do not need it, since you are reusing the mortise that is already cut.
