Hager WT1279 3-1/2X6 US26D – Frequently Asked Questions

1) How heavy a door will the Hager WT1279 hinge carry?
Medium weight doors, at medium frequency service. That is the WT1279's stated duty level, and it maps to ANSI A8133. If you have a heavy wood or a heavy hollow metal leaf, or an entrance that cycles hard all day, step up to a heavy weight hinge instead, for example the McKinney TCA3386 or the BEST CB223.
2) Can I swap a 3-1/2 x 6 wide throw hinge into a standard 3-1/2 x 3-1/2 mortise?
Not directly. A wide throw hinge shares the 3-1/2 inch height but the leaf runs 6 inches, so the existing mortise on the jamb and door edge is too shallow and has to be routed out to the deeper leaf. Screw pattern and frame reinforcing change with it. Plan on re-prepping the opening, or on a new frame, when you go to the WT1279. If the opening is already prepped standard and you just need a like for like, a standard full mortise hinge in the existing size is the swap.
3) What is the closest equivalent to the Hager WT1279 if the door has a closer on it?
The WT1279 is a plain bearing hinge and Hager's own application note says to use a ball bearing hinge where a door closer is present. For a closer-equipped opening, the Don-Jo BB74545 is a full mortise ball bearing hinge in steel with a square corner and 5-knuckle barrel, matching the WT1279's 5-knuckle full mortise arrangement while carrying the bearing type a closer calls for. The McKinney TCA2314 is another square corner 5 knuckle full mortise hinge for the same situation.
4) The WT1279 is medium duty - what full mortise hinge should be used on a heavy door instead?
The WT1279 is rated medium duty, which suits medium weight doors at medium frequency. For a heavier leaf, the McKinney TCA3386 is a heavy weight square corner 5 knuckle full mortise hinge in the same 5-knuckle full mortise pattern, and the Stanley Security CB199 is a full mortise concealed bearing heavy weight hinge from the Architectural Hinges series. Both are rated heavy duty rather than medium.
5) Can a standard weight full mortise hinge replace a wide throw hinge like the WT1279?
Not reliably. Wide throw is the feature that lets the WT1279 swing a door clear of deep trim, wraps, or a projecting frame condition. A standard weight hinge such as the Stanley Security CB1960R full mortise concealed bearing standard weight hinge or the BEST 1900R will match on full mortise prep and medium duty rating but will not produce the extra throw, so the door can strike the trim. If the opening needs clearance rather than throw specifically, the BEST CB248 is a full mortise swing clear hinge for square edge doors, which moves the leaf out of the opening entirely.
6) What looks like a substitute for the WT1279 but has a different leaf size?
The WT1279 measures 3-1/2 inches by 6 inches, which is the wide throw proportion - the leaf is taller across than it is high. Several comparable full mortise hinges are square 4-1/2 by 4-1/2, including the Don-Jo BB74545, the McKinney TCA2314 and the McKinney TCA2317, and the Don-Jo BB74540 is 4-1/2 by 4. Those will not drop into a mortise cut for a 3-1/2 by 6 leaf, so the frame and door prep has to be verified before swapping.
7) Do I need to order a left hand or right hand version of the Hager WT1279?
No handing to specify. The WT1279 is a full mortise butt hinge with a five knuckle barrel and a non-rising removable pin, so the same hinge works on a left or right hand door; you just flip it and drop the pin in from the top. What you do need to get right is quantity per leaf and the box option, since the hinges ship three to a box.
8) How many hinges do I need per door and how do they come packed?
The WT1279 is sold in boxes of three, 24 to a case, which suits the usual commercial practice of three hinges on a standard height door and four on a taller leaf. Order in multiples that match your door count rather than per piece, and if you are hanging a run of openings the case of 24 covers eight three-hinge doors.
9) Will the Hager WT1279 work on a hollow metal frame or only on wood?
Both. Full mortise means each leaf lets into a mortise, one in the door edge and one in the frame rabbet, which is the standard prep on hollow metal frames and on wood doors and jambs alike. The WT1279 is steel with a steel pin and is catalogued for commercial openings, so it suits hollow metal frames with tapped hinge reinforcing as well as wood. Confirm your frame reinforcing is prepped for the 6 inch leaf, not a standard leaf.
10) What is the difference between a plain bearing hinge and a concealed bearing hinge?
Plain bearing hinges ride metal on metal at the knuckle and suit medium weight, medium frequency doors with no closer. Concealed bearing hinges hide the bearing inside the barrel so it looks like a plain butt but carries closer loads and higher cycles. If the sightline matters but the door has a closer on it, the BEST 1900R or the Stanley Security CB1960R are medium duty steel concealed bearing full mortise hinges with a removable pin. The WT1279's advantage over both is its wide throw, which neither of those offers.
11) Where do the hinges go on the door and how do I lay out the mortises for the WT1279?
Hager publishes a standard hinge locations sheet and a full mortise size option chart for this hinge, both available as part of the WT1279's documentation. Use the locations sheet to set top, bottom, and intermediate hinge centers on the door and the matching frame rabbet, then cut the mortise to the 6 inch leaf rather than a standard leaf depth. Cutting the frame to a standard 3-1/2 inch mortise and then trying to fit the wide throw is the mistake that costs a frame.
12) Is there a version of a full mortise hinge that carries power to the door, like an electrified WT1279?
The WT1279 is a non-electronic hinge. Where power has to cross the opening to an electrified lock or exit device, the ACSI 5BB1 is a 5 knuckle ball bearing full mortise hinge with concealed electric through-wire in a 4 wire 28 gauge configuration, from the 1100 Series. It is a ball bearing hinge rather than plain bearing, so the bearing type changes along with the electric transfer.
13) Which hinge should I specify instead of the WT1279 if the door has a beveled edge?
The WT1279 is a wide throw full mortise plain bearing hinge and is not edge-profile specific in the way some architectural hinges are. Where the door carries a beveled edge, the BEST CB223 is a stainless steel concealed bearing heavy weight pivot reinforced hinge built for beveled edge doors. For square edge doors the BEST FBB212 is the ball bearing heavy weight pivot reinforced equivalent.
14) Do any comparable full mortise hinges come in brass or stainless instead of steel?
The Hager WT1279 is steel with a steel pin, supplied in 626 satin chrome. Among comparable full mortise ball bearing hinges, the Don-Jo BB84545 is brass in satin chrome and the Don-Jo BB94545 is stainless steel with a square corner, both 4-1/2 inch by 4-1/2 inch. The BEST CB223 is a stainless steel hinge as well. Base material matters where the opening sees moisture or an exterior exposure.
15) Which comparable hinges hold the same medium duty rating as the Hager WT1279 for standardizing across a facility?
The WT1279 is a commercial medium duty hinge certified to ANSI A8133. The BEST 1900R and the Stanley Security CB1960R are both rated medium duty full mortise concealed bearing standard weight hinges from the Architectural Hinges series, and the BEST CB248 is medium duty in a full mortise swing clear form. Those three sit at the same duty level, which is the starting point when a facility wants one rating across its openings.
16) Can I take the door off without unscrewing the hinges from the frame?
Yes. The WT1279 uses a non-rising removable pin with a button tip and plug, so you tap the pin out and lift the leaf off with both hinge halves still fastened. That is what a property manager wants for pulling a door to move furniture or to swap a damaged leaf. Note it is a plain removable pin, not a non-removable or security pin, so on an out-swinging exterior opening the pin is accessible from outside.
17) Is the Hager WT1279 hinge ANSI rated for a commercial spec?
It carries ANSI A8133 and Hager builds to ANSI/BHMA A156.1. On a submittal where the drawing calls a steel, medium weight, full mortise plain bearing butt, A8133 is the number the specifier is looking for. It is a commercial grade product, not a residential one.
18) What is the difference between the McKinney TCA2314 and TCA2317 when cross-referencing a Hager wide throw hinge?
Both the McKinney TCA2314 and the TCA2317 are square corner 5 knuckle full mortise hinges at 4-1/2 inches by 4-1/2 inches and both are rated standard duty, so they sit adjacent to each other in the same family. Neither carries the wide throw leaf proportion of the Hager WT1279, whose leaf is 3-1/2 by 6. Confirm the required throw and the existing mortise before cross-referencing either one against a wide throw position.
