Hager 1279-4.5X4.5-US26D – Frequently Asked Questions

1) Will the Hager 1279 hinge work on a commercial door with a steel frame, and how much prep does it need?
The 1279 is a full mortise hinge, so both leaves get mortised in: one into the door edge, one into the frame rabbet, so the leaves sit flush. That means the frame has to be prepped (or already hinge-prepped, which most hollow metal frames are) and the door edge routed to match. It is a steel hinge rated for commercial use, medium duty, standard weight. If your frame is not prepped and you cannot rout it, a full mortise hinge is the wrong choice for that opening.
2) Is a plain bearing hinge like the Hager 1279 heavy enough for a high traffic door, or do I need ball bearing?
Plain bearing means the knuckles ride metal on metal with no bearing race. The 1279 is medium duty, standard weight, and that is the right call for interior openings with moderate use, light doors, and no closer. For a door with a closer on it, a heavy or oversized door, or a main entry that cycles all day, go to a bearing hinge instead: the Don-Jo BB74545 is a 4-1/2 x 4-1/2 steel ball bearing full mortise hinge with the same 5-knuckle build, and the McKinney TCA3386 is a heavy weight 4-1/2 x 4-1/2 square corner option.
3) What size Hager 1279 hinge do I order for a 1-3/4 inch commercial door?
For a standard 1-3/4 inch commercial door the usual call is 4-1/2 x 4-1/2, and that size is offered. The 1279 runs 3.5 x 3.5, 4 x 3.5, 4 x 4, 4.5 x 4, 4.5 x 4.5, 5 x 4, 5 x 4.5 and 5 x 5. The first number is hinge height, the second is open width: go taller for door weight, wider only when you need extra clearance for trim or a thicker door. The 3.5 x 3.5 and 4 x 4 sizes are the residential and light interior end of the range.
4) Should I get removable pin or non removable pin on the Hager 1279?
Both are offered, and the choice comes down to which way the door swings. On an out-swinging exterior or secure-side door, the hinge barrel is exposed, so a non removable pin (NRP) stops someone pulling the pin and lifting the door out. On an in-swinging door the barrel is on the protected side, and a removable pin makes it far easier to take the door down for painting, moving furniture, or replacing the slab. Property managers standardizing a building usually spec NRP everywhere the hinge is on the outside and removable on everything interior.
5) Do I need square corner or radius corner hinges for my door?
Match what is already cut. The 1279 comes with a standard (square) corner or a radius corner. Machine-prepped hollow metal doors and frames usually have a router-cut radius corner mortise, and dropping a square corner leaf into it leaves gaps at the corners. Wood doors mortised by hand, and older prepped frames, are typically square. If you are replacing existing hinges, pull one off and look at the corners of the pocket before you order, because corner style is not something you can change in the field without recutting the mortise.
6) Can the Hager 1279 be used as an electric through-wire hinge for an access control door?
No. The 1279 is a mechanical hinge with no electrical option, so it will not carry power or signal to an electrified lock or exit device. For a through-wire opening use a purpose-built electric hinge: the ACSI 5BB1 is a 5 knuckle ball bearing full mortise hinge in 4-1/2 x 4-1/2 with a concealed electric through-wire, 4 conductor 28 gauge. Put the electric hinge in the middle position and run standard 1279 hinges top and bottom on the same door.
7) Is the Hager 1279 the right hinge for a heavy door or one with a lot of abuse?
No. Medium duty, standard weight, steel and plain bearing puts the 1279 on ordinary interior and light exterior doors. For a heavy slab, a high-abuse opening, or a door that needs pivot reinforcement, step up: the BEST CB223 is a stainless steel concealed bearing heavy weight pivot reinforced hinge for beveled edge doors, and the Dormakaba CB199 is a heavy weight full mortise concealed bearing hinge. Both are heavy duty. Putting a standard weight plain bearing hinge on a heavy door is how you end up with sag and a door that drags inside a year.
8) What is the difference between a Hager 1279 plain bearing hinge and a ball bearing hinge like the Don-Jo BB74545?
The Hager 1279 is a plain bearing hinge, meaning the knuckles ride directly on each other rather than on bearing races. The Don-Jo BB74545 is a full mortise ball bearing hinge in steel, 4-1/2 inch by 4-1/2 inch, square corner, 5-knuckle. Both are 5-knuckle full mortise hinges that route flush into the door edge and frame. The bearing type is the deciding factor: plain bearing suits medium duty openings with moderate traffic and no closer, while ball bearing construction is the usual choice where a door closer drives the door or the leaf is heavy. The 1279 is ANSI A8133 certified and rated Medium Duty.
9) What hinge should I use instead of the Hager 1279 on a heavy weight door?
The Hager 1279 is a standard weight, medium duty hinge, so a heavy weight opening calls for a different part. The McKinney TCA3386 is a square corner 5 knuckle full mortise hinge, 4-1/2 inch by 4-1/2 inch, heavy weight, rated Heavy Duty. The Stanley Security CB199 is a full mortise concealed bearing heavy weight hinge, also Heavy Duty. Both mortise into the door and frame the same way the 1279 does, so the frame prep concept is unchanged, but confirm leaf dimensions against the existing cutout before ordering.
10) Is the BEST 1900R an equivalent to the Hager 1279?
The BEST 1900R is a steel full mortise standard weight hinge with a removable pin, rated Medium Duty, and it uses concealed bearings. The Hager 1279 is also steel, full mortise, standard weight and Medium Duty, and it is available with a Removable pin. The two match on material, mounting, weight class and duty rating, so the 1900R lines up closely on the opening it serves. The distinction is the bearing: the 1279 is plain bearing while the 1900R is concealed bearing. The BEST CB1960R is another concealed bearing full mortise standard weight hinge at Medium Duty.
11) Is the Hager 1279 ANSI certified, and what does A8133 mean for a spec sheet?
It carries ANSI A8133. In the ANSI/BHMA hinge numbering that identifies it as a full mortise steel hinge in the standard weight, plain bearing class, which is the line an architect or facility spec writer looks for when the drawing calls out a hinge type rather than a brand. If the door schedule lists A8133, the 1279 answers it directly.
12) Can I get the Hager 1279 hinge in black, or in a finish I can paint?
Thirteen finishes are offered: 600 primed for painting, 605 bright brass, 606 satin brass, 612 satin bronze, 613 satin bronze oil-rubbed, 619 satin nickel, 620 antique nickel, 625 bright chrome, 626 satin chrome, H2H mechanical galvanized, L1 flat black, LS Luma Sheen, and US10A antique bronze. The 600 primed option is what you order when the hinges get painted to match the door or frame, and H2H mechanical galvanized is the one to pick where corrosion is a concern. Flat black is L1.
13) How many hinges do I need per door and where do they go?
Hinge count follows door height, not the hinge model: two for short doors, three on a standard 7 foot door, four on taller leaves. Placement for the 1279 follows Hager's standard hinge location layout, which sets the top, bottom and intermediate hinge dimensions from the head and sill, and the size options sheet confirms which of the 3.5 x 3.5 through 5 x 5 sizes suits your door thickness and trim clearance. Order the same quantity per opening in one finish, corner and pin type so the door looks and behaves consistently.
14) My door binds on the frame when it opens. Will a Hager 1279 fix the clearance?
Not likely. The 1279 is a conventional full mortise hinge, so the door still pivots close to the frame and the leaf remains in the opening when the door is wide open. If you need the full clear width, for a wheelchair or a gurney through a narrow opening, you want a swing clear hinge instead, such as the BEST CB248, a steel full mortise concealed bearing swing clear hinge for square edge doors, medium duty. That style swings the door completely out of the opening. A standard hinge in a wider open width will not do the same thing.
15) Which hinges can standardize a whole building alongside the Hager 1279?
The Hager 1279 covers standard medium duty openings in steel, ANSI A8133, in eight sizes from 3.5 x 3.5 through 5 x 5 and thirteen finishes. Three peers extend that program to the openings the 1279 is not meant for: the McKinney TCA3386 and Stanley Security CB199 are heavy weight full mortise hinges at Heavy Duty for high traffic or heavy leaves, and the BEST CB248 is a swing clear full mortise hinge at Medium Duty for openings that must yield full clear width. Holding one finish across all four keeps a facility visually consistent while each opening gets the correct hinge.
16) What do I order instead of the Hager 1279 for a beveled edge door?
The Hager 1279 is a full mortise hinge; hinge selection for a beveled edge leaf is a separate part. The BEST CB223 is a stainless steel concealed bearing heavy weight pivot reinforced hinge made for beveled edge doors, rated Heavy Duty. For a square edge door in a heavy weight application, the BEST FBB212 is a steel ball bearing pivot reinforced hinge for square edge doors. Check the door edge condition before ordering, since a hinge cut for one edge profile will not sit flush on the other.
17) I need a stainless steel or brass hinge rather than steel. What matches the Hager 1279?
The Hager 1279 is a steel hinge, offered in finishes including 605 Bright Brass, 606 Satin Brass, 626 Satin Chrome and H2H Mechanical Galvanized. If the base material itself has to change, the Don-Jo BB94545 is a full mortise ball bearing hinge, 4-1/2 inch by 4-1/2 inch, stainless steel, square corner, and the Don-Jo BB84545 is a full mortise ball bearing hinge, 4-1/2 inch by 4-1/2 inch, brass, in Satin Chrome. Both are Standard Duty. On exterior or wash-down openings the base metal matters more than the plated finish, which is where the stainless leaf earns its place.
18) What is the difference between the McKinney TCA2314 and TCA2317 as alternatives to the Hager 1279?
Both McKinney parts are square corner 5 knuckle full mortise hinges at 4-1/2 inch by 4-1/2 inch, and both are rated Standard Duty; the model number is what separates them in a distributor's order. The Hager 1279 is also a 5 knuckle full mortise hinge and covers 4-1/2 inch by 4-1/2 inch among its sizes, plus 3.5 x 3.5, 4 x 3.5, 4 x 4, 4-1/2 x 4, 5 x 4, 5 x 4-1/2 and 5 x 5, and it is available with a Standard Corner or a Radius Corner. If the existing frame prep has rounded corners, the radius corner 1279 drops in without refiling the mortise, where a square corner hinge would not.
19) I need a 4-1/2 by 4 inch hinge in satin chrome. Does the Hager 1279 cover that or do I need the Don-Jo BB74540?
Both cover it. The Hager 1279 is offered in 4-1/2 inch by 4 inch and in 626 Satin Chrome, as a steel plain bearing hinge rated Medium Duty and certified ANSI A8133. The Don-Jo BB74540 is a full mortise ball bearing hinge, 4-1/2 inch by 4 inch, in Satin Chrome, rated Standard Duty. The 1279 in that size can also be specified with a Removable or Non Removable pin and a Standard or Radius corner, which is what to settle if you are matching existing frame prep or an out-swinging exterior door where a non removable pin is required.
20) I need to cross reference an old commercial hinge to a Hager number. Is there a chart?
Yes. Hager publishes a commercial hinge cross reference that maps competitor hinge designations to the equivalent Hager model, which is how you get from a hinge stamped with another brand's number to the 1279 or its siblings. Pull the hinge, read the stamp on the leaf, and look it up there. Confirm weight class and bearing type when you cross over, since the 1279 lands specifically as standard weight and plain bearing.
