Hager WTBB1279 3.5X5 U26 – Frequently Asked Questions

1) What is a wide throw hinge like the Hager WTBB1279 for, and when do I need one instead of a standard hinge?
A wide throw hinge has longer leaves than a standard hinge so the door swings further clear of the frame or wall. The WTBB1279 is the wide throw version of Hager's full mortise ball bearing line, and you can see it in the sizes: leaf heights run 3.5, 4, 4.5 and 5 inches, but widths go out to 6, 7 and 8 inches, well past the square 4-1/2 x 4-1/2 of a standard hinge. Reach for it when deep trim, thick casing, a wall return or a projecting frame would otherwise stop the door short, or when you need the door to swing back flat against the wall. If the opening is ordinary, a square-leaf hinge in the same 5-knuckle ball bearing pattern does the job with less material.
2) Is the Hager WTBB1279 heavy enough for a solid core commercial door?
It's rated medium duty, for medium weight doors or openings seeing medium frequency service. That covers most solid core wood and hollow metal doors on offices, classrooms and tenant suites. Where it isn't the right call is a high traffic entrance, a heavy lead-lined or oversized door, or a stairwell that cycles all day. For those, step up to a heavy weight hinge such as the McKinney TCA3386 or the BEST CB223.
3) Can the Hager WTBB1279 hinge be used to run power to an electrified lock or exit device?
Yes, it accepts concealed electric modifications: EMN for monitoring only, ETW for through-wire only, ETM for through-wire with monitoring, and Quick Connect. That's how you get power across the opening to an electric strike, electrified lever trim or a mag lock monitor without a surface loop. Specify the modification when you order, and put the electrified hinge in the position your wiring run calls for. The base hinge itself is not an electronic product; the electric function comes from the modification.
4) Can you pull the pin on the Hager WTBB1279 to take the door off?
The pin is non-rising and removable, with a button tip and plug. Pull the plug, drive the pin out and the door lifts off, which is what you want for a door you will need to service or move furniture through. It also means the pin will not walk up out of the knuckle over time. Note this is a standard removable pin, not a non-removable pin (NRP), so on an out-swinging door in a secure area you should specify security studs or an NRP option rather than relying on this as-is.
5) Do I need a wide throw hinge or will a standard ball bearing hinge work on my door?
If the door swings clear today and you're just replacing worn hardware, you don't need wide throw. A square-leaf ball bearing hinge like the Don-Jo BB74545 or the McKinney TCA2314, both 4-1/2 x 4-1/2, does that job. Go wide throw when the door hits trim, a wall return or deep casing before it opens far enough, or when you need it to lay back against the wall for clearance. The WTBB1279 gets you there with leaf widths out to 8 inches.
6) My door binds on the trim when it opens. Will a wide throw hinge fix it?
That's exactly the problem wide throw solves. Swapping to a wider leaf moves the pivot point further out from the frame, so the door clears the obstruction instead of striking it. Measure how much extra clearance you need, then step up the leaf width: the WTBB1279 runs 5, 6, 7 and 8 inch widths. What it will not fix is a door that binds because it's sagging or the frame is out of square, so check the reveal at the top corner before you order hinges.
7) Will the Hager WTBB1279 hinge work on an aluminum storefront or a door with a beveled edge?
It's a full mortise hinge, so it needs a mortised leaf pocket in both the door edge and the frame rabbet, the standard prep on hollow metal and solid core wood doors. It is not a storefront pivot or a continuous gear hinge, so it is not the part for a glass-front aluminum entrance. For a beveled edge door needing pivot reinforcement, the BEST CB223 is built for that condition; for a square edge door, the BEST FBB212 is the pivot reinforced equivalent.
8) I need the door leaf to swing completely out of the doorway for wheelchair clearance - is the WTBB1279 the right hinge?
No. The WTBB1279 is a wide throw hinge, which moves the door away from the frame so it clears trim or a deep reveal, but the leaf still sits in the opening when the door is open. To recover the full clear width of the opening, use a swing clear hinge: the BEST CB248 is a steel full mortise concealed bearing swing clear hinge for square edge doors, rated Medium Duty, the same duty level as the WTBB1279. That is the hinge type that folds the door fully clear of the frame, which is what an accessible corridor or a hospital opening usually requires. Confirm the door edge profile as well, since the CB248 is prepped for square edge doors.
9) What is the closest equivalent to the Hager WTBB1279 ball bearing hinge from another manufacturer?
For a medium duty steel full mortise bearing hinge, the BEST 1900R is the nearest peer. The BEST 1900R is a steel full mortise concealed bearing standard weight hinge with a removable pin, and it carries a Medium Duty rating, matching the Medium Duty rating of the WTBB1279. The Stanley Security CB1960R is a second option at the same level, also a full mortise concealed bearing standard weight hinge rated Medium Duty. The difference to confirm before ordering is the bearing style: the WTBB1279 uses two exposed ball bearings between the knuckles, while both the 1900R and the CB1960R use concealed bearings, which changes the look of the knuckle stack on a door where the hinges are visible. The WTBB1279 is also a wide throw hinge, so if the opening needs the door to clear trim or a deep reveal, the standard throw peers will not reproduce that swing geometry.
10) The door is too heavy or the traffic too high for a medium duty hinge - what should I use instead of the WTBB1279?
The WTBB1279 is rated Medium Duty, intended for medium weight doors and medium frequency service. When the leaf is heavier or the opening cycles harder, step up to a heavy weight hinge. The McKinney TCA3386 is a square corner 5 knuckle full mortise hinge in 4-1/2 inch by 4-1/2 inch rated Heavy Duty. The Stanley Security CB199 is a full mortise concealed bearing heavy weight hinge, also Heavy Duty. For a heavy door that additionally needs pivot reinforcement, the BEST CB223 is a stainless steel concealed bearing heavy weight pivot reinforced hinge for beveled edge doors, rated Heavy Duty. Note that none of these three is a wide throw hinge, so if the extra throw is what is holding the door clear of trim, that requirement has to be solved separately.
11) Is a Don-Jo BB74545 a substitute for the Hager WTBB1279?
They are both steel full mortise ball bearing hinges with a 5 knuckle build, so the family is right, but they are not interchangeable in every opening. The Don-Jo BB74545 is a 4-1/2 inch by 4-1/2 inch square corner steel hinge rated Standard Duty; the WTBB1279 is Medium Duty and is a wide throw hinge, sold in leaf sizes from 3-1/2 by 5 inches up to 5 by 8 inches. The width difference is the deciding point: a 4-1/2 by 4-1/2 hinge is square, while every WTBB1279 size is wider than it is tall, which is what pushes the door away from the frame on swing. If the door prep was cut for a wide throw hinge, the BB74545 will not reproduce the clearance. If the opening only ever needed a standard square hinge, the Don-Jo is the simpler part.
12) I need an electrified hinge to run power to an electric strike or lock - can I order the WTBB1279 that way, or do I need a different part?
The WTBB1279 accepts electric modifications: EMN for monitoring only, ETW for through-wire only, ETM for through-wire with monitoring, and Quick Connect. That means the same hinge you are already specifying can carry the wire to the door. If you would rather buy the electrified hinge as a finished assembly, the ACSI 5BB1 is a 5 knuckle ball bearing full mortise hinge, 4-1/2 inch by 4-1/2 inch, supplied with a concealed electric through-wire in a 4 wire 28 gauge configuration. The tradeoff is geometry: the ACSI 5BB1 is a square 4-1/2 by 4-1/2 hinge, so it will not give you the wide throw the WTBB1279 provides. On an opening that needs both wide throw and power transfer, order the WTBB1279 with the ETW or ETM modification rather than substituting.
13) A pivot reinforced hinge was specified on the drawing - is the WTBB1279 that hinge?
No. Pivot reinforced is a distinct construction and the WTBB1279 is a standard full mortise ball bearing hinge, not a pivot reinforced one. If the drawing calls for pivot reinforcement, the BEST FBB212 is a steel ball bearing heavy weight pivot reinforced hinge for square edge doors, and the BEST CB223 is a stainless steel concealed bearing heavy weight pivot reinforced hinge for beveled edge doors, rated Heavy Duty. Pick between them on door edge profile and material. The WTBB1279 remains the right choice where the spec calls for a wide throw medium duty bearing hinge rather than pivot reinforcement.
14) Does the Hager WTBB1279 meet ANSI/BHMA requirements for a commercial spec?
It carries the ANSI/BHMA designation A8112, which is the architectural hinge code a specifier writes against. That plus the steel construction and commercial rating is what gets it accepted on an office, school, healthcare or government job where the drawings call out a certified hinge rather than a builder-grade one.
15) How many hinges do I need to order, and do they come in a box of three?
There's a box package option of three pieces, which is how doors are normally hinged: three hinges on a standard height commercial door. Choose Yes on the box package if you want the three-pack, or No to buy by the piece for a single replacement or a fourth hinge on a tall or heavy leaf. Order the same size and finish across the opening so the door hangs square.
16) Is the Hager WTBB1279 handed? Do I need to specify left or right?
No handing to specify. A full mortise butt hinge with a removable pin is symmetrical, so the same hinge works on a left hand or right hand door. What you do need to match is leaf size and finish across the opening, plus the electric modification if one hinge in the set is carrying wire.
17) Can I standardize a whole building on the Hager WTBB1279?
For medium weight doors on medium frequency openings, yes, and it's a reasonable standard for offices, classrooms, exam rooms, retail back-of-house and multi-tenant corridors. One ANSI A8112 steel hinge, one finish, ordered in three-packs, keeps your stockroom simple. Where you'll need to break the standard is on your high traffic entrances and any oversized or unusually heavy leaf, which want a heavy weight hinge instead, and on openings where the door has to clear the full width, which want swing clear.
18) Is a steel hinge like the WTBB1279 OK for an exterior or damp opening?
The leaves and pin are steel, which is the standard commercial material for interior openings and holds up well behind a finish. For exterior doors, coastal sites, pool rooms, kitchens or anywhere washdown and salt are in play, go stainless instead: the Don-Jo BB94545 is a stainless steel full mortise ball bearing hinge, and the BEST CB223 is stainless as well. Solid brass is another option for corrosion resistance, as on the Don-Jo BB84545.
19) What is the difference between the ball bearing hinges and the concealed bearing hinges when I am replacing an existing hinge?
It is what you see in the knuckle stack and what the door prep expects. The WTBB1279 carries two ball bearings between its five knuckles, visible as bearing races in the barrel, with a non-rising removable pin fitted with a button tip and plug. The BEST 1900R and the Stanley Security CB1960R are concealed bearing hinges, where the bearing sits inside the knuckle and the barrel reads as a plain cylinder; both are full mortise standard weight hinges rated Medium Duty. The BEST CB248 and the Stanley Security CB199 are also concealed bearing designs. Functionally all of them are bearing hinges rather than plain bearing, so the smooth operation is comparable. On a run of doors where some hinges are already installed and visible, matching the barrel appearance is usually the reason to pick one style over the other.
20) The opening is in a corrosive or wash-down area - what bearing hinge should I use instead of a steel one?
The WTBB1279 is built from steel with a steel pin, which suits dry interior commercial openings but not a location that sees moisture or chemicals. For a corrosion-resistant equivalent, the Don-Jo BB94545 is a stainless steel full mortise ball bearing hinge, 4-1/2 inch by 4-1/2 inch with a square corner. The BEST CB223 is also stainless steel, a concealed bearing heavy weight pivot reinforced hinge for beveled edge doors. If the concern is appearance rather than corrosion, the Don-Jo BB84545 is a brass full mortise ball bearing hinge in 4-1/2 inch by 4-1/2 inch and satin chrome. All three are square 4-1/2 by 4-1/2 sizes, so verify the existing frame prep before substituting for a wide throw hinge.
21) My doors have beveled edges - does that change which hinge I can order?
Yes, the door edge profile has to be matched. Several peer hinges are cut for a specific edge: the BEST CB223 is a stainless steel concealed bearing heavy weight pivot reinforced hinge specified for beveled edge doors, while the BEST FBB212 is a steel ball bearing heavy weight pivot reinforced hinge for square edge doors, and the BEST CB248 swing clear hinge is likewise for square edge doors. If your doors are beveled and you are working at a heavy weight opening, the CB223 is the one prepped for that edge. Confirm the edge on the actual door before ordering, since a square edge hinge on a beveled door will not sit flush in the mortise.
22) I am standardizing hinges across a building - if I only need a plain square hinge on the interior doors, what is the simpler option alongside the WTBB1279?
Use the wide throw WTBB1279 only where the opening actually needs the extra throw, and put a standard square hinge on the rest. The McKinney TCA2314 and McKinney TCA2317 are both square corner 5 knuckle full mortise hinges in 4-1/2 inch by 4-1/2 inch, rated Standard Duty. The Don-Jo BB74545 is another square corner 5 knuckle steel full mortise ball bearing hinge at 4-1/2 by 4-1/2, also Standard Duty, and the Don-Jo BB74540 is a 4-1/2 inch by 4 inch full mortise ball bearing hinge in satin chrome. All of these share the 5 knuckle build with the WTBB1279, so the knuckle count reads the same down a corridor. Match finish across the building by picking the same nominal finish family; the WTBB1279 is offered in 605 bright brass, 612 satin bronze, 613 satin bronze oil-rubbed, 625 bright chrome, 626 satin chrome, 600 primed for painting, LS Luma Sheen, and US10A antique bronze.
23) What finishes does the Hager WTBB1279 hinge come in?
Eight: 600 primed for painting, 605 bright brass, 612 satin bronze, 613 satin bronze oil-rubbed, 625 bright chrome, 626 satin chrome, LS Luma Sheen, and US10A antique bronze. For matching a building already standardized on brushed hardware, 626 satin chrome is the one that lines up. If the frames are getting painted out, 600 primed saves you a coat of prep.
