Installation & Operation

  2. Use manufacturer-provided templates to mark mounting hole locations accurately on door and frame surfaces, ensuring proper alignment with frame and door leaf alignment ribs.
  3. Prepare door and frame by drilling required holes for standard #12-24 X 11/16" Flat Head Dril-Kwik screws or optional fasteners as specified.
  4. Install hinge with proper 5/16" (8mm) hinge side clearance plus standard lockside clearance for square edged doors on hinge side.
  5. Secure the hinge to door and frame per manufacturer torque specifications, utilizing door edge protection tip during installation.
  6. Test hinge operation to verify smooth function and proper door alignment. For doors over 200 lbs, verify 16-gauge channel reinforcement is properly installed. Refer to manufacturer documentation for complete installation details and electric modification procedures.

Hager HAG-780-124HD-83-CLR – Frequently Asked Questions

1) Will the Hager 780-124HD continuous hinge work on a door that sits deep inset or flush with the frame?
That's exactly what the concealed leaf geometry on the 780-124HD is for. Both leaves hide inside the opening, so it suits deep inset openings and flush-with-frame installs where the frame is rabbeted, plus center hung doors and heavy cabinet work. If your door swings on a standard butt-style full mortise frame with no rabbet, a concealed leaf gear hinge is the wrong choice and a full surface or half surface continuous hinge is the one to spec.
2) What length Hager 780-124HD do I order for a 7 foot door, and can I cut it down?
The 780-124HD is stocked in 79, 83, 85, 95 and 119 inch lengths. A standard 7 foot (84 inch) door takes the 83 inch hinge, since a continuous geared hinge runs just short of the full door height. Pick the length from the door, not the frame, and order the length that fits rather than trimming, the gear teeth and end caps are machined to the finished length.
3) Do I need to reinforce the door for a Hager 780-124HD continuous hinge?
No door reinforcement is required up to 200 lbs. Above that, run a 16-gauge channel in the door edge. That threshold is the practical dividing line on lead lined, heavy timber and clad doors, weigh the leaf before you assume you are under it.
4) Can the Hager 780-124HD carry electric wiring through to an electrified lock or exit device?
It takes electric modifications: Power Transfer Preparation in EPT 2 or EPT 10, Electric Through-Wire (ETW), and Electric Monitoring (EMN). Specify the modification when you order, it is machined into the hinge and cannot be added on site. Wire count and conductor gauge are set by whatever device you are feeding, so size the transfer to the lock or device first.
5) What screws come with the Hager 780-124HD and do I need to tap the door?
Standard fasteners are Dril-Kwik #12-24 x 11/16 inch flat head screws. Dril-Kwik is a self-drilling, self-tapping screw, so on hollow metal you drive straight into the face without pre-drilling and tapping. Use the manufacturer template to lay out the hole line, and set the frame and door leaf alignment ribs to locate the hinge before you drive anything.
6) Is there a Hager 780-124HD version for a hospital x-ray room lead lined door?
Yes, a lead lined configuration is built for x-ray room doors, with a double row of fasteners that straddle the lead so the screws do not compromise the shielding. Specify LL on the order. Hospital tip and TIPIT options are also offered for healthcare openings where a projecting top cap is a snag or tamper risk.
7) Why use a continuous geared hinge instead of three butt hinges on a high traffic door?
A butt hinge concentrates the whole door weight on two or three points, and in a high traffic opening those points wear, the door sags, and the latch stops lining up. The Roton geared hinge runs the full height of the door and spreads the load along its entire length, which cuts the lateral wear that causes sag. The 780-124HD is the heavy duty version, built for high frequency doors or heavy doors in medium frequency service, which covers school corridors, hospital wings and warehouse access.
8) What finishes does the Hager 780-124HD come in, and will they match across a building?
Three finishes: clear aluminum (CLR), dark bronze (DBZ) and black (BLK). All three are offered in every length from 79 through 119 inches, so a facility standardizing on one look can run the same finish across doors of different heights. Clear is the usual match to clear anodized aluminum storefront framing, dark bronze to bronze anodized entrances.
9) Is the Hager 780-124HD aluminum strong enough for a commercial opening?
The extrusion is 6063-T6 aluminum, a heat treated temper rather than raw soft aluminum, and the hinge is rated commercial only, not a residential part. Strength on a geared continuous hinge comes from the full height load path more than from a single knuckle, which is why the aluminum body still handles doors up to 200 lbs with no door reinforcement at all.
10) Does the Hager 780-124HD protect the door edge, and how do I keep it aligned during install?
A door edge protection tip is part of the hinge, along with alignment ribs on both the frame leaf and the door leaf that locate the hinge correctly before the first screw goes in. On a full height hinge that matters, a hinge started out of plumb at the top is 8 feet out of plumb at the bottom, and you will chase the latch afterward.
