Hager HAG-780-112HD-83-CLR – Frequently Asked Questions

1) Will the Hager 780-112HD continuous hinge work on a 1-3/4 inch door?
That's exactly the door it's built for. The 780-112HD is a continuous geared hinge for doors 1-3/4 inches (44 mm) thick, in both standard and heavy duty forms. Heavy duty, which is what the HD designation covers, is the version for high frequency doors or heavy doors seeing medium frequency traffic. On a thinner door, say a 1-3/8 inch older interior leaf, this is not the hinge to spec.
2) What lengths does the Hager 780-112HD hinge come in, and how do I pick one for my door height?
Four lengths are offered: 79, 83, 85 and 119 inches, plus 95 inches. A continuous geared hinge runs nearly the full height of the leaf, so pick the length that fits under your door height without running past the top or bottom rail. A standard 7-foot opening usually takes the 83 inch; 8-foot doors take the 95; the 119 inch covers tall entrance leaves. Every length is stocked in all three finishes.
3) Can I use a continuous geared hinge on a fire rated door opening?
The 780-112HD carries up to a 3-hour fire rating on metal doors and 90 minutes on wood composite doors with studs. It also meets ANSI/BHMA A156.26 C. For a rated opening, confirm the door and frame label matches the duration you need, then the hinge is not the limiting element up to those hours.
4) Can the Hager 780-112HD hinge run wiring for an electric lock or access control?
Yes, through electric modifications ordered on the hinge. Options are power transfer preparation (EPT 2 or EPT 10), exposed electric contacts (E), switches (E1S), through-wire (ETW), monitoring (EMN), and combined through-wire plus monitoring (ETM). Through-wire is what you want to feed an electrified lock or exit device in the leaf; monitoring reports door position back to the panel. These are ordering options, so specify the modification when you place the order, not after.
5) What is the difference between a concealed leaf continuous hinge and a full surface one?
A concealed leaf hinge like the 780-112HD mounts into the hinge edge of the door and the frame rabbet, so the barrel is the only thing you see when the door is closed. A full surface hinge screws onto the face of the door and frame instead, which is easier to retrofit onto an existing opening but leaves hardware visible. Concealed leaf is the choice where appearance matters, on new work, or where face-mounted hardware would foul a frame stop. The 780-112HD takes 5/16 inch (8 mm) hinge side clearance plus standard lockside clearance, which is what the door prep has to allow for.
6) Why use a continuous geared hinge instead of three butt hinges on a high traffic door?
Butt hinges carry the door's weight at three points, and on a high-cycle opening those points wear, the door sags, and the latch stops lining up with the strike. A Roton geared continuous hinge spreads the load along the full height of the leaf instead, which is why the 780-112HD is specified for high frequency doors and for heavy doors on medium frequency openings. On a school corridor, a hospital wing, or a warehouse entrance, that is the difference between a door you adjust every year and one you do not.
7) Is there a version of the Hager 780 continuous hinge for a lead lined x-ray room door?
There is. A lead lined model of the 780-112HD is built with a double row of fasteners so the screws straddle the lead in the door. Specify LL when ordering. On a hospital imaging suite the standard hinge would put fasteners through the shielding, which is the reason the lead lined version exists.
8) What finishes does the Hager 780-112HD hinge come in, and will it match the other doors in my building?
Three finishes: clear aluminum (CLR), dark bronze (DBZ), and black (BLK). All three are available in every length offered, so a mixed set of door heights across a building can be standardized on one appearance. Clear aluminum is the usual match for aluminum storefront and mill-finish frames; dark bronze pairs with bronze anodized entrances.
9) What screws come with a Hager Roton 780-112HD hinge and do I need to tap the door?
Standard fasteners are Dril-Kwik #12-24 x 11/16 inch flat head screws. Dril-Kwik screws drill and tap their own hole in hollow metal as they drive, so you are not pre-tapping every hole on a 95 inch run. Use the manufacturer template to lay out the hole pattern on both the door and frame before you start.
10) How do I keep a continuous hinge from twisting out of alignment during installation?
The 780-112HD has alignment ribs on both the frame leaf and the door leaf. They set the hinge's position for you as you seat it, so the leaf lands square instead of walking out of plumb over a 7 or 8 foot run. Hang and shim off those ribs, then check the full swing before you drive the balance of the fasteners.
11) Is the Hager 780-112HD an aluminum hinge, and will it hold up in a warehouse or exterior entrance?
It's extruded aluminum, 6063-T6. That alloy does not rust, which is why geared continuous hinges are common on exterior and high-humidity openings where steel butts corrode at the pin. It is rated commercial, not residential, and specified for high frequency traffic, so a warehouse man-door or a main entrance is within what it is built for.
