Hager 790-909 83 US32D – Frequently Asked Questions

1) Will the Hager 790-909 continuous hinge work on an 8-foot door, and what length do I order?
The 790-909 covers doors up to 10'-0" in length. Standard lengths are 79", 83", 85", 95" and 119". Pick the hinge length that suits the door height, so a 7'-0" door typically takes the 83" or 85" and a 10'-0" door takes the 119". Nonstandard lengths are available, but any nonstandard length may need a custom hole pattern, and Hager asks to be consulted on the field prep for the door and frame in that case.
2) What does the swing clear design on the Hager 790-909 actually do for ADA clearance?
A swing clear hinge carries the door completely out of the opening when it swings to 90 degrees, so the door leaf no longer eats into the clear width. On a narrow corridor door or a restroom that's a couple inches short of the required clear opening, that's usually the cheapest way to gain the width without moving the frame. The 790-909 is built for exactly that kind of ADA upgrade work and is ADA certified. It needs 1/8" minimum clearance on the hinge side plus your standard lockside clearance.
3) Can I use the Hager 790-909 on a fire-rated opening?
Yes. The 790-909 is UL listed with fire ratings up to 3 hours on metal doors and 90 minutes on wood composite doors.
4) Do I need to reinforce the door for the Hager 790-909, and how much weight will it hold?
It carries up to 200 lbs with no door or frame reinforcement on wood doors. Above that, use 16-gauge channel reinforcement. On metal doors Hager recommends a 1/8" (3 mm) thick reinforcement plate along the hinge edge so the adjustment studs get proper thread engagement.
5) Does the Hager 790-909 fit a 1-3/4 inch door, and does it work on a beveled edge?
Maximum door thickness is 1-3/4", which covers standard commercial doors. The 790-909 is made for either beveled or square edge doors, and it carries a 1/8" inset.
6) If I want swing clear but can't use a continuous hinge, what else is there?
The BEST CB248 is a swing clear butt hinge, steel full mortise with concealed bearings, built for square edge doors and listed medium duty. It mortises into existing hinge prep instead of running the full door height, which suits a single door where you only need the clear width and don't want to re-prep the edge. The Hager 790-909 is the continuous option, and it's the one to use when the door is heavy, high traffic, or up to 10'-0" tall.
7) The door needs power transfer to an electrified lock. Will the Hager 790-909 do that?
For a hinge that carries power through to the door, the ACSI 5BB1 is a 4-1/2 inch by 4-1/2 inch five knuckle ball bearing full mortise hinge with concealed electric through-wire, 4 wire 28 gauge. The Hager 790-909 is a mechanical full surface continuous geared hinge; its listed options are wide throw, replacement moldings, security fasteners, security studs and Dutch door prep, with optional sex bolts. Use the ACSI 5BB1 at the power transfer location when an electrified lock or exit device needs wiring through the hinge edge.
8) What swing clear hinge can be used instead of the Hager 790-909 when the opening takes standard butt hinges?
The BEST CB248 is a steel full mortise concealed bearing swing clear hinge for square edge doors, and it is the closest swing clear alternative in butt hinge form. The difference is the format: the Hager 790-909 is a full surface continuous geared hinge in 14 gauge Type 304 stainless steel that runs the full height of the opening in lengths of 79, 83, 85, 95 and 119 inches, while the CB248 is a mortised leaf hinge installed in individual pairs or sets at spaced hinge locations. Choose the CB248 when the door and frame are already prepped for butt hinge mortises and you only need the swing clear geometry for clear width; choose the 790-909 when you want full-length weight distribution on a door up to 10 feet.
9) For a heavy commercial door, is a heavy weight butt hinge an equivalent to the Hager 790-909 continuous hinge?
They solve the load problem differently. Heavy weight butt hinges such as the BEST CB223 stainless steel concealed bearing pivot reinforced hinge for beveled edge doors, the Dormakaba CB199 full mortise concealed bearing heavy weight hinge, and the McKinney TCA3386 square corner 5 knuckle heavy weight hinge carry the door at three or four discrete points. The Hager 790-909 is a full surface continuous geared hinge that distributes door weight along the entire hinge length, supporting up to 200 lbs without door or frame reinforcement and up to 3 hour fire ratings on metal doors. If the door is beveled edge, the CB223 is listed for beveled edge doors, while the 790-909 is stated for beveled or square edge doors.
10) What fasteners do I need for the Hager 790-909 on a hollow metal frame versus a wood frame?
Fasteners break out by substrate: #10-24 x 5/8" stainless Dril-Kwik for metal frames, #1/4-20 x 3/4" 2C Dril-Kwik for metal doors, and #1/4-14 x 1" 2C Type AB for wood frames. Sex bolts are available as an option and have to be specified at time of order.
11) What options can I add to a Hager 790-909 order for a school or detention-type opening?
Security is handled through options rather than a separate model: security moldings, security fasteners, and security studs. Other add-ons are wide throw, replacement moldings (M), and Dutch door prep (DUTCH). All of these are specified at the time of order.
12) Is a geared continuous hinge worth it over three butt hinges on a high-traffic door?
On a heavily used opening, yes. Butt hinges concentrate the load at three or four points, which is where hinge sag and frame wear start. The Roton geared continuous hinge spreads door weight along the entire hinge length, cutting lateral wear. The 790-909 is 14 ga. (0.075") Type 304 stainless with a 1/4" diameter stainless pin and dual 6/6 nylon bearings between each knuckle. Where traffic is light and you just need a standard replacement, a butt hinge like the Don-Jo BB94545 stainless full mortise or the McKinney TCA2314 is the simpler swap.
13) Is the Hager 790-909 a surface-applied hinge or does it mortise into the door edge?
It is a full surface hinge. It mounts to the face of the door and the face of the frame, so there's no mortising of the door edge or frame rabbet. That makes it workable on a retrofit where the existing hinge prep is worn out or where you don't want to machine an existing door. Heavy weight butt hinges such as the BEST CB223 or the Dormakaba CB199 are full mortise and require that prep.
14) What is a simpler hinge to use on interior doors that do not need the swing clear ADA geometry of the Hager 790-909?
Standard duty full mortise ball bearing butt hinges cover ordinary interior openings. The Don-Jo BB74545 is a 4-1/2 by 4-1/2 inch steel square corner 5 knuckle ball bearing hinge, the BB94545 is the same size in stainless steel with square corners, the BB84545 is brass in satin chrome, and the BB74540 is a 4-1/2 by 4 inch version in satin chrome. The McKinney TCA2314 and TCA2317 are also 4-1/2 by 4-1/2 inch square corner 5 knuckle standard duty hinges. None of these provide the swing clear, 1/8 inch inset configuration that makes the Hager 790-909 suited to ADA clear width upgrade work on commercial openings.
15) Is a concealed bearing standard weight hinge like the BEST 1900R a substitute for the Hager 790-909?
No, they are different classes of hinge. The BEST 1900R is a medium duty steel full mortise concealed bearing standard weight hinge with a removable pin, and the Stanley Security CB1960R is a comparable medium duty concealed bearing standard weight full mortise hinge. Both are leaf hinges mortised into the door and frame edge. The Hager 790-909 is a full surface continuous geared hinge in 14 gauge Type 304 stainless steel with a 1/4 inch stainless pin and dual 6/6 nylon bearings between each knuckle, mounted to the face of the door and frame and running the full opening height. A removable pin standard weight hinge will not deliver the continuous support or the swing clear clear width the 790-909 is built for.
16) What should I use on a square edge door that needs pivot reinforcement rather than a continuous hinge?
The BEST FBB212 is a steel ball bearing pivot reinforced hinge for square edge doors, and the BEST CB223 is the stainless steel concealed bearing heavy weight pivot reinforced equivalent for beveled edge doors. Pivot reinforced hinges add a reinforcing element at the top hinge to handle concentrated load. The Hager 790-909 takes a different approach on square edge or beveled doors: as a full surface continuous geared hinge it spreads the load along the whole leaf and needs a 1/8 inch thick reinforcement plate along the hinge edge on metal doors for thread engagement of the adjustment studs, while wood doors need none up to 200 lbs.
17) What finish does the Hager 790-909 continuous hinge come in?
One finish only: 630 satin stainless steel (US32D). That's the same finish across all five stock lengths, so a building standardizing on satin stainless will match across openings without mixing finishes.
18) Will the Hager 790-909 hold up in a coastal or wash-down environment?
Construction is Type 304 stainless steel throughout the leaf, with a 1/4" diameter stainless steel pin, so corrosion resistance is good for exterior and humid interior openings. The bearings are 6/6 nylon rather than steel, which means nothing in the pivot path to rust. Steel-bodied butt hinges like the BEST FBB212 or the Don-Jo BB74545 are a different proposition in that environment.
