Installation & Operation

  1. Review manufacturer specifications and verify door preparation requirements including door thickness, mullion width from 1-1/2" (38mm) to 2-1/4" (57mm), and frame face clearance of 1-5/8" (41mm) minimum plus 3/16" (5mm) rotational clearance.
  2. Use manufacturer-provided templates to mark mounting hole locations accurately on door and mullion surfaces, ensuring 1/32" (1mm) minimum clearance between mullion and door.
  3. Prepare doors and mullion by drilling required holes for 1/4-20 x 1-1/4" Sexbolt fasteners and #12-24 X 11/16" Pan Head Screws as specified in manufacturer instructions.
  4. Install mounting hardware and secure the hinge to doors and mullion per manufacturer torque specifications, ensuring proper 1/16" (1.5mm) inset alignment.
  5. Adjust operational components for proper alignment, smooth operation, and security molding fit throughout the full range of motion for both doors.
  6. Test hinge operation to verify proper function of both doors and make final adjustments as needed. Refer to manufacturer documentation for complete installation details and troubleshooting.

Hager HAG-780-257HD-83-CLR – Frequently Asked Questions

1) What is the Hager 780-257HD continuous hinge actually used for?
It hangs two entrance doors off one fixed mullion. The 780-257HD is a double continuous geared hinge, meaning a single unit carries both leaves of the pair from the mullion faces, with security moldings and a 1/16 inch (1.5mm) inset. If you have a pair of doors in a frame with jamb hinging rather than a center mullion, this is the wrong configuration.
2) What mullion width does the 780-257HD fit?
Mullion widths from 1-1/2 inch (38mm) up to 2-1/4 inch (57mm). Allow 1/32 inch (1mm) minimum clearance between the mullion and each door, plus normal lockside clearance. Measure the mullion face before ordering, because outside that 1-1/2 to 2-1/4 inch band this hinge will not set up correctly.
3) Can the Hager 780-257HD be used on a fire rated pair of doors?
Yes. Up to 3 hours on metal doors, and 90 minutes on wood composite doors when studs are used. It also meets ANSI/BHMA A156.26 Grade C. Institutional buyers standardizing on rated openings can spec it on both metal and wood composite pairs.
4) Do I need to reinforce the doors before installing this hinge?
No door reinforcement is required up to 200 lbs per leaf. Above that weight, use a 16-gauge channel. That is one of the practical reasons to move a heavy high-traffic pair to a geared continuous hinge instead of butts, since the load spreads along the full length rather than at three or four points.
5) For a high traffic double entrance, is a continuous geared hinge or a stainless heavy weight butt hinge the better choice?
The Hager 780-257HD is built for high frequency doors or heavy, medium frequency doors, needs no door reinforcement to 200 lbs, and carries up to a 3-hour fire rating on metal doors. Among butt hinges, the BEST CB223 is a stainless steel concealed bearing heavy weight pivot reinforced hinge for beveled edge doors rated heavy duty, and the Dormakaba CB199 is a full mortise concealed bearing heavy weight hinge, also heavy duty. The continuous hinge spreads load over the full door height and hangs both leaves off the mullion; the butt hinges mortise into an existing three-hinge prep and suit beveled or square edge doors respectively.
6) What is the difference between the Hager 780-257HD continuous geared hinge and a heavy weight butt hinge like the McKinney TCA3386?
The Hager 780-257HD is a full surface continuous geared hinge in aluminum 6063-T6 that runs the full height of the opening in 79, 83, 85, 95 and 119 inch lengths, distributing door weight along the entire hinge. The McKinney TCA3386 is a square corner 5 knuckle full mortise hinge, 4-1/2 inch by 4-1/2 inch, rated heavy duty, so the door load is carried at three or four discrete points and each leaf is mortised into the door and frame. The 780-257HD also mounts two doors from a fixed mullion 1-1/2 inch to 2-1/4 inch wide, which a butt hinge does not do.
7) The doors need extra clear width for ADA wheelchair passage. Is the Hager 780-257HD the right hinge?
The Hager 780-257HD is a full surface continuous geared hinge for hanging two entrance doors from a fixed mullion with security moldings and a 1/16 inch inset; it does not move the door leaf out of the opening. For added clear opening width, a swing clear hinge is the type to specify, such as the BEST CB248, a steel full mortise concealed bearing swing clear hinge for square edge doors rated medium duty.
8) How much frame face and rotational clearance does this mullion-mount hinge need?
Plan on 1-5/8 inch (41mm) minimum frame face, plus 3/16 inch (5mm) of rotational clearance. Check that on site before you drill, especially on storefront and narrow-face mullions where the available flat is tight.
9) What fasteners come with the Hager 780-257HD?
It ships with 1/4-20 x 1-1/4 inch Sexbolts (fastener plus post) and Dril-Kwik #12-24 x 11/16 inch pan head screws. The Sexbolt count covers both the 052A and 052B halves. No extra reinforcement kit is needed unless the leaf is over 200 lbs.
10) What finishes does the Hager 780-257HD come in, and can I match existing aluminum storefront?
Three finishes: clear aluminum (CLR), dark bronze (DBZ) and black (BLK). All five lengths (79, 83, 85, 95, 119 inch) are offered in each of the three. Clear anodized matches most mill-finish aluminum storefront; dark bronze is the usual match for bronze-anodized entrances.
11) Is the 780-257HD full mortise or full surface? Do I have to mortise the doors?
It mounts full surface. The hinge leaves apply to the face of the doors and the mullion, so there is no hinge pocket to route and no edge prep, which is what makes it a practical retrofit on doors already hanging. You are drilling for the Sexbolts and pan head screws only.
12) I am replacing butt hinges on an existing storefront pair. Will the old holes be a problem?
Not usually a blocker. Since the 780-257HD is surface applied to the door and mullion faces rather than into the hinge edge, existing butt hinge mortises on the jamb side are not reused, and you drill fresh per the Hager template. Two things do decide it: the mullion has to measure 1-1/2 to 2-1/4 inch wide, and you need 1-5/8 inch of frame face plus 3/16 inch rotational clearance. Hager also publishes a commercial hinge cross reference if you are matching an existing model.
13) For a lighter interior door that does not see heavy traffic, is there a simpler alternative to the Hager 780-257HD?
The Hager 780-257HD is specified for commercial high frequency doors or heavy, medium frequency doors and mounts two doors off a mullion. On a lighter interior opening, a standard weight butt hinge covers it: the BEST 1900R is a steel full mortise concealed bearing standard weight hinge with a removable pin, rated medium duty, and the Stanley Security CB1960R is a full mortise concealed bearing standard weight hinge, also medium duty. Both drop into a conventional mortise prep rather than running the full door height.
14) Can I use ball bearing butt hinges such as the Don-Jo BB74545 instead of the Hager 780-257HD?
Only if the opening is a conventional hinge-jamb hang. The Don-Jo BB74545 is a full mortise ball bearing hinge, 4-1/2 inch by 4-1/2 inch, steel, square corner, 5-knuckle, rated standard duty, and it is also offered in brass as the BB84545 and stainless steel as the BB94545. The Hager 780-257HD is a full surface continuous geared hinge that hangs two doors from a fixed mullion 1-1/2 inch to 2-1/4 inch wide, so the mounting location and prep are different and the two are not interchangeable on the same opening.
15) I need power transfer through the hinge for an electric strike or exit device. Can this do it?
Continuous geared Roton hinges can be supplied with a concealed electric modification, and Hager publishes both the concealed electric hinge modification sheet and electric hinge installation instructions for that option. If you only need power transfer at one leaf of a pair and want to keep butt hinges, a through-wire butt such as the ACSI 5BB1 with 4-wire 28ga concealed through-wire is the simpler route.
16) Is this hinge approved for commercial buildings or is it a residential product?
Commercial. Hager classes the 780-257HD as a commercial continuous geared hinge, with the A156.26 Grade C rating and fire ratings that go with office, school, healthcare, retail and municipal entrances. It is overbuilt for a house door.
17) What replaces the Hager 780-257HD if the door height only needs a 4 inch leaf hinge and the frame is already prepped?
The Hager 780-257HD comes only in full-height 79, 83, 85, 95 and 119 inch lengths because it is a continuous geared hinge. For an existing standard mortise prep with a narrower leaf, 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 McKinney TCA2314 and TCA2317 are square corner 5 knuckle full mortise hinges at 4-1/2 inch by 4-1/2 inch, also standard duty.
