Hager RC1748 3-1/2X3-1/2 US26 – Frequently Asked Questions

1) Does the corner radius on the Hager RC1748 have to match my existing hinge pocket?
It does. The RC1748 has 1/4 inch (6 mm) radius round corners, which drops into a pocket routed with a standard hinge template or router jig. If your door and frame are prepped with square corners (chiselled by hand or factory square prep), a round corner hinge will leave a gap at each corner of the mortise. Match round to round, square to square, or re-cut the pocket.
2) Do I need to order left hand and right hand versions of the Hager RC1748?
No. The RC1748 is reversible, so one part number covers both left hand and right hand openings. For a property manager stocking a fleet of apartment doors that means a single SKU on the shelf regardless of which way each door swings. The pin is removable, so you can also pull the leaves apart to take a door off without unscrewing the hinge.
3) Is the Hager RC1748 plain bearing hinge heavy enough for an apartment entry door that gets used all day?
The RC1748 is a plain bearing hinge built to ANSI A8134, which is a residential weight classification. Plain bearing means the knuckles ride directly on each other with no ball or concealed bearing race, so it suits normal residential traffic on interior and unit entry doors. For a high traffic opening, a door with a closer on it, or anything commercial weight, step up to a bearing hinge such as the McKinney TCA2314 or the Don-Jo BB74545, both 4-1/2 by 4-1/2 inch ball bearing hinges.
4) Can the Hager RC1748 hinge be used on a hollow metal frame, or is it only for wood?
It is listed for use on metal frame, and the fastener pack reflects that: it ships with both machine screws and wood screws (10-24 x 1/2 inch machine, number 9 x 1 inch wood). So the frame leaf can be machine screwed into a tapped hollow metal jamb while the door leaf takes wood screws into a wood slab. No separate fastener order is needed.
5) Can I use the Hager RC1748 on a fire rated door or a commercial opening?
The RC1748 is classified residential weight to ANSI A8134, so it is the wrong hinge for a commercial or labelled opening. For those, use a full mortise bearing hinge built for the duty: the BEST 1900R and the Stanley Security CB1960R are standard weight concealed bearing hinges, and for heavy weight the Dormakaba CB199 or the McKinney TCA3386. Those are 4-1/2 inch class hinges, so the door and frame prep must suit.
6) Will the Hager RC1748 line up with holes already drilled from a hinge template?
Yes. The RC1748 uses a template hole pattern, so the screw holes sit at the standardized locations a factory prepped door or frame is machined to. On a replacement job that usually means the new hinge drops onto the existing holes without redrilling, provided the size is 3-1/2 by 3-1/2 inches and the corners are the 1/4 inch radius type.
7) What is the RC1748 made of, and will it hold up in a corridor that gets damp?
Steel leaves with a steel pin, 0.085 gauge. Steel takes a finish well and carries residential loads fine, but in a genuinely wet or coastal environment the base metal is the limiting factor. For those openings a stainless hinge such as the Don-Jo BB94545 (4-1/2 by 4-1/2 inch stainless steel, square corner) or a brass hinge like the Don-Jo BB84545 handles moisture better, both being larger and ball bearing rather than a direct size swap.
8) What hinge gives full clear opening width for an ADA doorway instead of a standard full mortise hinge like the RC1748?
A standard full mortise hinge such as the RC1748 leaves the open door sitting in part of the opening, since the leaf mortises into the door edge and frame rebate. Where the full clear width has to be recovered, a swing clear hinge carries the door out of the opening: the BEST CB248 is a steel full mortise concealed bearing swing clear hinge for square edge doors, medium duty, in the Swing Clear Hinges series. Check the door edge first, since the CB248 is cut for a square edge.
9) Is a concealed bearing hinge the same thing as the plain bearing Hager RC1748?
No. The RC1748 uses a plain bearing barrel with 5 knuckles, where the knuckles turn directly on each other. A concealed bearing hinge hides the bearing inside the barrel so the barrel looks plain from the outside but rides on a bearing. The BEST 1900R is a steel full mortise concealed bearing standard weight hinge with a removable pin, medium duty, and the Stanley Security CB1960R is a full mortise concealed bearing standard weight hinge, also medium duty and in the Architectural Hinges series. If someone specified a hinge on a drawing because it looked plain barrelled, confirm whether the spec calls for concealed bearing before treating a plain bearing hinge as the same part.
10) What is the difference between a steel hinge like the Hager RC1748 and a stainless steel or brass hinge of the same style?
The RC1748 is steel with a steel pin. Among comparable full mortise ball bearing hinges at 4-1/2 inch by 4-1/2 inch, the Don-Jo BB74545 is steel with a square corner, the Don-Jo BB94545 is stainless steel with a square corner, and the Don-Jo BB84545 is brass in satin chrome. All three are standard duty. Material choice drives corrosion behavior at exterior and wash-down openings and drives what base metal the finish is plated over, so a fleet being standardized on one substrate should confirm the base metal, not only the finish code.
11) Which hinge suits a door with a beveled edge rather than the square edge a Hager RC1748 goes on?
The RC1748 is a full mortise plain bearing hinge with 1/4 inch radius round corners and a template hole pattern. For a beveled edge door, the BEST CB223 is a stainless steel concealed bearing heavy weight pivot reinforced hinge made for beveled edge doors. The square edge counterpart in the same family of pivot reinforced hinges is the BEST FBB212, a steel ball bearing heavy weight pivot reinforced hinge for square edge doors, listed as standard duty. Confirm the door edge before ordering, because the leaf geometry is cut for one or the other.
12) What finishes does the Hager RC1748 3-1/2 inch hinge come in?
Seven orderable finishes on the 3-1/2 by 3-1/2 inch size: 605 bright brass, 606 satin brass, 619 satin nickel, 625 bright chrome, 626 satin chrome, US10A antique bronze, and US10R dark bronze. If you are matching existing hardware across a building, 626 satin chrome and 619 satin nickel are the two that read closest to brushed stainless trim, and 626 also matches the Don-Jo BB74540 satin chrome ball bearing hinge if you need a heavier hinge on a few openings in the same finish family.
13) Is a 5 knuckle hinge better than a 3 knuckle for a residential door?
Five knuckles spread the door load over more of the barrel than three, which is why the RC1748 uses that pattern. The practical effect is less sag over time on a solid core slab and a smoother swing. On a plain bearing hinge like this the knuckle count is the load story, since there is no bearing race doing the work.
