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

1) Will the Hager 780-112 continuous hinge work on a 1-3/8 inch door?
No. The Roton 780-112 is a single-thickness hinge built for doors 1-3/4 inches (44 mm) thick, and that applies to both the standard duty and heavy duty versions. On a 1-3/8 inch door, which is the common older interior thickness, you need a different hinge model entirely.
2) What lengths does the Hager 780-112 geared continuous hinge come in, and which one do I order for a 7-foot door?
Three lengths: 79 inches, 83 inches, and 95 inches. A standard 7-foot (84 inch) door takes the 83 inch hinge, which runs nearly the full leaf height without bottoming on the floor. The 95 inch length covers 8-foot openings, and 79 inches suits shorter doors. All three are offered in clear aluminum, dark bronze, and black.
3) Does the Hager 780-112 hinge carry a fire rating for a 3-hour stair or corridor door?
Yes on metal doors. The 780-112 Roton concealed leaf hinge is rated up to 3 hours on metal doors, and 90 minutes on wood composite doors when studs are used. If your opening is a wood composite leaf, plan on the 90 minute limit, not the 3 hour figure.
4) How much clearance does a concealed leaf continuous hinge need on the hinge side of the door?
The 780-112 needs 5/16 inch (8 mm) on the hinge side, plus standard lockside clearance. Concealed leaf means the hinge tucks into the gap between door and frame instead of wrapping the door edge, so that 5/16 inch gap is what makes the installation work. If your existing opening is prepped tighter than that, the door edge will bind.
5) Can I run access control wiring through the Hager 780-112 hinge?
Yes, but it is an ordered option, not standard. The 780-112 is available with Power Transfer Preparation (EPT 2 or EPT 10), Exposed Electric Contacts (E), Electric Through-Wire (ETW), and Electric Monitoring (EMN). Pick ETW for feeding power to an electrified lock or exit device, EMN if the panel needs door position monitoring. Specify the electric modification at the time you order, since the hinge is machined for it at the factory.
6) Should I use a concealed leaf continuous hinge or a full mortise butt hinge set on a high traffic commercial door?
On a door that gets cycled hard, the continuous geared hinge is the better call. Butt hinges concentrate the whole door weight on two or three knuckles, which is where sag and screw pull-out start. The Roton 780-112 runs the full height of the leaf and spreads the load along its length, cutting lateral wear. It also hides the gear channel between the door and frame for a clean edge, where a continuous geared hinge with an exposed cap is visible from the hinge side.
7) Is there a lead lined continuous hinge for an x-ray room door?
Yes. Specify the 780-112 as an LL model and it ships with a double row of fasteners that straddle the lead in the door, so the screws do not compromise the shielding. This is the version for hospital x-ray and imaging room doors.
8) What screws come with the Hager 780-112 continuous hinge?
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, so on a steel door and frame you are not pre-drilling and tapping every hole down the length of the hinge. Follow the Roton instruction sheet for hole spacing and the fastener pattern.
9) What finish should I order to match the aluminum storefront doors already in my building?
Clear aluminum (CLR) is the match for standard clear anodized aluminum storefront. Dark bronze (DBZ) matches bronze anodized entrances, and black (BLK) is the third choice. All three finishes are available in every length, 79, 83, and 95 inches. The hinge body is 6063-T6 aluminum, the same alloy family used for the extrusions in those storefront frames, so it holds up outdoors on entrance openings.
10) Does the Hager 780-112 meet ANSI/BHMA A156.26 for continuous hinges?
The 780-112 is compliant with ANSI/BHMA A156.26 Grade C. That is the continuous hinge standard your architect or facility spec will reference, so this satisfies a spec calling out A156.26 C.
11) Will a continuous geared hinge stop my exterior door from sagging and dragging on the threshold?
That is the main reason people move to one. Sag on a butt-hinged door starts when the top hinge takes the whole moment and the screws work loose in the frame. The Roton 780-112 runs the full leaf height and carries the weight along its entire length, so there is no single overloaded point. It handles doors to 200 lbs with no frame reinforcement, and the 6063-T6 aluminum resists corrosion on exterior openings.
12) Can I get a hospital tip on the Hager 780-112 continuous hinge?
Hospital tip is an available option on the 780-112. It bevels the end of the hinge so gurneys, carts, and clothing do not catch on a square corner, which is why healthcare facilities call for it on patient room and corridor doors.
