Hager HAG-780-046HD-83-CLR – Frequently Asked Questions

1) Will the Hager 780-046HD continuous hinge work on a 1-3/4 inch door?
No. The 780-046HD is sized for a 1-3/4 inch (45 mm) frame with a 1-3/8 inch (35 mm) door, and it covers the frame rabbet completely at that combination. On a standard 1-3/4 inch commercial door you need a different half surface geared hinge sized for that thickness.
2) Do I have to reinforce the door for a Hager 780 continuous hinge?
Not up to 200 lbs. Doors heavier than that should get a 16-gauge channel for reinforcement. Standard fasteners are 1/4-20 x 1-1/4 inch sexbolts (fastener plus post), with #12-24 x 11/16 inch flat head screws called out as the alternative.
3) Can the 780-046HD be used on a fire rated opening?
Yes. Hager rates this continuous geared hinge up to 3 hours on metal doors and 90 minutes on wood composite doors when studs are used.
4) Can I run power through the door with the Hager 780-046HD for an electrified lock?
Yes, it can be ordered with power transfer preparation, either EPT 2 or EPT 10, for concealed wire transfer to electrified locks or exit devices. That is a factory modification, so specify it when you order rather than trying to add it in the field.
5) What is the difference between the Hager 780-046HD continuous geared hinge and the BEST F173 half surface hinge?
Both mount as half surface hinges, but they are different constructions. The Hager 780-046HD is a continuous geared hinge in aluminum 6063-T6 that runs the full height of the door and distributes weight along its entire length, offered in 79, 83, 85, 95 and 119 inch lengths. The BEST F173 is a steel half surface hinge with a removable pin and plain bearing, rated medium duty, and is installed as individual leaves at standard hinge locations rather than as one continuous piece. The 780-046HD is described as heavy duty for high frequency doors or heavy medium frequency doors.
6) Can the BEST F173 be substituted for the Hager 780-046HD on a fire rated opening with electrified hardware?
Plan on the Hager 780-046HD for that opening. It carries up to a 3-hour fire rating on metal doors and 90 minutes on wood composite doors with studs, and it can be ordered with power transfer preparation, EPT 2 or EPT 10, for electrified hardware. The BEST F173 is a medium duty steel half surface hinge with a removable pin and plain bearing and does not offer those geared continuous hinge features.
7) What is a half surface continuous geared hinge and when do I use one instead of butt hinges?
A half surface hinge mortises into the frame on one leaf and surface mounts to the door face on the other, so the geared barrel runs the full height of the opening. Instead of concentrating load on three or four butt hinges, the 780-046HD spreads door weight along its entire length, which is why it is used on high frequency doors or heavy doors in medium frequency service. It is a commercial product, not a residential one.
8) What lengths and finishes does the Hager 780-046HD come in?
Five lengths, 79, 83, 85, 95 and 119 inches, each available in clear aluminum (CLR), dark bronze (DBZ) and black (BLK). Pick the length that matches your door height; the 95 and 119 inch sizes cover tall and oversized openings.
9) How much hinge side clearance do I need for this Hager continuous hinge?
Allow 5/32 inch (4 mm) minimum on the hinge side. The frame leaf also carries an alignment rib that sets hinge location during install, and the security molding has a 9/32 inch (7 mm) inset.
10) What is the 780-046HD made of, and will it hold up in a high traffic entrance?
The hinge is extruded aluminum 6063-T6, geared, and rated heavy duty for high frequency traffic. Because the gear barrel carries the door along its full height, it does not develop the sag and lateral wear that shows up on butt hinges in schools, hospitals and office entrances.
11) For a medium duty opening that does not need a full height hinge, what half surface hinge can be used instead of the Hager 780-046HD?
The BEST F173 is a steel half surface hinge in the Architectural Hinges series, rated medium duty, with a removable pin and plain bearing. It suits openings where individually located butt style hinges are acceptable. The Hager 780-046HD is the choice when the opening is high frequency or the door is heavy, since the geared continuous design carries the load along the full leaf and requires no frame reinforcement up to 200 lbs.
12) Does the BEST F173 cover the frame rabbet the way the Hager 780-046HD does?
No. The Hager 780-046HD is built to provide complete frame rabbet coverage for 1-3/4 inch frames with 1-3/8 inch doors, and includes security molding with a 9/32 inch inset plus a frame leaf alignment rib. The BEST F173 is a conventional steel half surface hinge with a removable pin and plain bearing, so it mounts at discrete hinge locations and leaves the rest of the rabbet exposed. If rabbet coverage or the security molding is part of the spec, the 780-046HD is the part to hold.
