Hager HAG-BB1109 4-1/2 US32D – Frequently Asked Questions

1) What is a half mortise hinge, and when do I use one instead of a full mortise?
On the Hager BB1109, one leaf mortises into the edge of the door and the other leaf surface applies to the frame. That is what makes it a half mortise. You use it where the frame cannot be mortised, typically channel iron frames on hollow metal doors. If both the door and the frame can take a mortise, a full mortise hinge is the normal choice instead.
2) Will the BB1109 hinge handle the traffic on a school or office corridor door?
It is rated medium duty for commercial use, and Hager states the application as medium weight hollow metal doors with channel iron frames at medium frequency service. Two ball bearings carry the load. For a high-traffic main entrance or a heavy door, step up to a heavy weight ball bearing hinge rather than pushing this one.
3) Do I have to order the BB1109 handed, left or right?
No. The beveled surface leaf makes it reversible, so the same hinge goes on a left hand or right hand door. You do not specify handing when ordering, only size and finish.
4) Is the Hager BB1109 ANSI certified for a spec job?
Yes. The brass version certifies to ANSI A2211 and the stainless steel version to ANSI A5211. Hager also states its commercial hinges are manufactured in accordance with ANSI/BHMA A156.1.
5) What is the difference between the Hager BB1109 and the BEST F173 half surface hinge?
Both are medium duty commercial half surface hinges with a removable pin, but they differ in bearing and material. The Hager BB1109 uses a ball bearing design - two ball bearings with a non-rising removable pin, button tip and plug - in brass with a stainless steel pin or stainless steel with a stainless steel pin. The BEST F173 is a steel hinge with a removable pin and a plain bearing rather than ball bearings. If the opening sees medium frequency service and you want bearing-borne pin wear, the BB1109 is the ball bearing option; the F173 is the plain bearing steel alternative at the same duty level.
6) What sizes and finishes does the Hager BB1109 come in?
Two sizes, 4-1/2 x 4-1/2 inch and 5 x 5 inch, each in four finishes: 600 primed for painting, 613 satin bronze oil-rubbed, 626 satin chrome, and 630 satin stainless steel. Both sizes are offered in all four, so a facility standardizing on one finish can mix sizes across openings.
7) What screws come with the BB1109 and what prep do I need?
Fastener sizes are called out as 1/2 inch x 12-24 flat head for the door leaf and 1/2 inch x 12-24 oval head for the jamb leaf, so both leaves take machine screws into tapped metal, not wood screws. Plan on tapped holes in the door edge for the mortised leaf and in the channel iron for the surface leaf.
8) Can the pin be pulled to take the door down for service?
Yes. The BB1109 uses a non-rising removable pin with a button tip and plug, so the pin comes out for maintenance without the leaves being disturbed, and it will not walk up out of the barrel in service.
9) Which material should I pick for a coastal or wash-down opening?
Choose the stainless steel with stainless steel pin option, certified to ANSI A5211, for corrosion resistance. The brass with stainless steel pin option (ANSI A2211) is the choice where you are matching a brass or bronze hardware set. Both use a stainless pin.
10) How do I find the Hager equivalent of a competitor's half mortise hinge I already have?
Hager publishes a 2021 commercial hinge cross reference that maps other manufacturers' hinge numbers to Hager models, which is the route to confirming the BB1109 is the right swap for what is on the door now. Match size and finish off the existing hinge as well, since the BB1109 comes in 4-1/2 x 4-1/2 and 5 x 5.
11) Is a plain bearing hinge an acceptable substitute for the Hager BB1109 on a commercial door?
It depends on how the opening is used. The BB1109 is specified for medium weight hollow metal doors with channel iron frames requiring medium frequency service, and its two ball bearings carry the leaf load for smooth, quiet operation. The BEST F173 is a steel half surface hinge with a plain bearing and a removable pin, also rated medium duty, so it covers the same duty class without the ball bearing assembly. On lower traffic openings the plain bearing F173 is the simpler build; where the door cycles often, stay with the ball bearing BB1109.
12) Does the BEST F173 have the same 5 knuckle build as the Hager BB1109?
The Hager BB1109 is a 5 knuckle standard weight hinge with two ball bearings and a non-rising removable pin with button tip and plug, plus a beveled surface leaf that lets it go on left or right hand doors. The BEST F173 is described as a steel half surface hinge with a removable pin and plain bearing in the Architectural Hinges series. Both share the removable pin concept, so if your existing schedule calls out a 5 knuckle ball bearing half surface hinge, the BB1109 is the direct fit.
13) How many hinges per door and where do they go?
The BB1109 is a 5 knuckle hinge, and Hager publishes a standard hinge locations sheet covering the spacing used on commercial doors. Typical commercial practice is three hinges on a door up to 7 feet 6 inches and a fourth added above that, so order quantity per leaf accordingly.
14) Can I get power transfer through this hinge for an electrified lock?
Hager publishes a concealed electric hinge modification sheet covering how its hinges are modified to carry wire through the barrel, plus installation instructions for electric hinges. If you need power transfer at the opening, specify the electric modification rather than assuming a standard BB1109 will pass wire.
