Hager HAG-780-235HD-83-CLR – Frequently Asked Questions

1) Will the Hager 780-235HD continuous hinge work on a 1-3/4 inch door?
No. The 780-235HD is built for doors 2 inches (51 mm) thick or greater, and the hinge side edge has to be square edged. On a standard 1-3/4 inch commercial door you need a different Roton model sized for that thickness.
2) What does the wide throw on the Hager 780-235HD actually give me, and how does it change my clearance?
Wide throw buys you room on the hinge side when the door or frame needs extra clearance, for example to swing clear of a deep frame return or trim. The 780-235HD gives 5/16 inch (8 mm) hinge side clearance, and you have to allow an extra 1/32 inch on top of the standard lockside clearance when you lay out the opening. Miss that 1/32 inch and the door binds on the strike side.
3) Can I use a Hager 780-235HD on a fire rated opening?
Yes. The 780-235HD carries a fire rating of up to 3 hours on metal doors and 90 minutes on wood composite doors with studs, and it is UL listed. Confirm the rating you need matches the door and frame label, since the hinge rating is a ceiling, not an upgrade to the assembly.
4) What lengths and finishes does the Hager 780-235HD concealed hinge come in?
Stocked lengths are 83 inches and 95 inches, each in three finishes: clear aluminum (CLR), dark bronze (DBZ), and black (BLK). The 780-235HD series is also catalogued at 79, 85, and 119 inches for taller or shorter leaves. For a standard 7 foot door the 83 inch is the usual pick; 95 inch covers 8 foot openings.
5) Should I use a concealed leaf continuous hinge or a full mortise butt hinge on a heavy traffic door?
A geared continuous hinge like the 780-235HD runs the full height of the door and spreads the weight along the whole edge instead of concentrating it at three or four knuckles, which is why it holds up on high frequency openings where butt hinges sag and the door starts dragging. It also hides in the gap when the door is closed. The trade-off is preparation: you need a square edged hinge side and 2 inch or thicker door stock. If the door is thinner or already prepped for butts, stay with butt hinges.
6) What screws come with the Hager 780-235HD and do I need to tap the door and frame?
Standard fasteners are Dril-Kwik #12-24 x 11/16 inch flat head screws, which cut their own threads in metal so you drill the pilot and drive them without separate tapping. Use the manufacturer template to lay out the holes, and set the hinge to the frame and door leaf alignment ribs so it seats square.
7) Can I get a Hager 780-235HD with a hospital tip, or wired for electrified hardware?
Hospital tip is a listed option on the 780-235HD, which is the choice on patient room and behavioral health doors where a square cap can catch. Electric through-wire modification is handled as a separate concealed electric hinge modification, so specify it at order time rather than trying to add it in the field.
8) Is the Hager 780-235HD hinge rated for commercial use, and what is it made of?
It is a commercial, heavy duty product, extruded from aluminum 6063-T6. Hager rates it for high frequency doors or heavy doors in medium frequency service, which is the profile of school corridors, hospital patient rooms, and multi-tenant common area doors.
9) I need to match a competitor's continuous hinge already on the other doors in the building. Is there a cross reference for Hager Roton hinges?
Yes, Hager publishes a commercial hinge cross reference that maps competing part numbers to the Roton equivalent, and it is available with the 780-235HD. Match on door thickness first (this one is 2 inches and up), then on length and finish so the new opening looks like the rest of the run.
