Hager WTBB1168 4-1/2X6 US15 – Frequently Asked Questions

1) Is the Hager WTBB1168 rated for a heavy door in a high traffic opening?
Yes. The WTBB1168 is a heavy duty, heavy weight commercial hinge carrying the ANSI A8111 designation, with four ball bearings and a five knuckle barrel to spread the load. That combination is what you specify for heavy doors in high frequency service, such as school corridors, hospital wings, or a main entry vestibule. For lighter interior doors in the same building, a standard or medium weight hinge like the BEST 1900R is the right call rather than paying for heavy weight everywhere.
2) Can I run power through this hinge for an electrified lock or a door position switch?
Yes. The WTBB1168 is available with concealed electric modifications: EMN for monitoring only, ETW for through wire only, ETM for through wire plus monitoring, and a Quick Connect option. ETW is what you use to feed an electric strike, electrified lever, or maglock at the door; EMN gives you a door position signal back to the access control panel with no power transfer. Specify the modification at time of order, because it is machined into the hinge and cannot be added in the field. Hager publishes both a concealed electric hinge modification sheet and electric hinge installation instructions for the wiring detail.
3) I need to replace an existing hinge on a door that swings clear of the opening. Does this one do that?
No. The WTBB1168 is a wide throw butt hinge, which moves the door away from the frame but keeps the leaf inside the opening when the door is open. If you need the door to fold completely out of the clear width, for a hospital or accessibility opening, a swing clear hinge is the different part, and ZenSupply carries the BEST CB248 steel full mortise swing clear hinge for square edge doors.
4) Is a standard duty ball bearing hinge like the Don-Jo BB74545 an acceptable substitute for the Hager WTBB1168?
They are built for different door weights. The Hager WTBB1168 is a heavy duty ball bearing full mortise hinge; the Don-Jo BB74545 is a 4-1/2 inch by 4-1/2 inch steel square corner 5-knuckle ball bearing full mortise hinge rated standard duty. The Don-Jo suits a lighter leaf on ordinary traffic, and it is a standard throw hinge, so it will not give a door the added projection the wide throw WTBB1168 provides. On a heavy commercial door or one that must clear deep trim, stay with the heavy duty wide throw hinge.
5) Which hinge should be ordered for an electrified opening instead of specifying the Hager WTBB1168 with an electric modification?
The ACSI 5BB1 is a 5 knuckle ball bearing full mortise hinge, 4-1/2 inch by 4-1/2 inch, supplied with concealed electric through-wire using four 28ga conductors, from the 1100 Series. It arrives already prepped for the wire run, which suits a job where the power transfer hinge is being bought as a finished item. The Hager WTBB1168 is offered with EMN monitor only, ETW through-wire, ETM through-wire with monitoring and Quick Connect modifications, so it is the choice when the electrified hinge also has to be heavy duty and wide throw to match the rest of the opening.
6) What replaces a 4-1/2 inch by 4 inch hinge on an existing door if the Hager WTBB1168 leaf is too wide for the frame?
The Don-Jo BB74540 is a full mortise ball bearing hinge in 4-1/2 inch by 4 inch, satin chrome, rated standard duty, and it fits a narrower existing mortise than the 4-1/2 inch by 6 inch Hager WTBB1168. Measure the existing cutout before ordering: the WTBB1168 6 inch leaf width is what delivers the wide throw, so dropping to a 4 inch leaf gives up that clearance and drops from heavy duty to standard duty.
7) Does the WTBB1168 hinge have to be handed when I order it?
No. A full mortise butt hinge of this type is symmetrical, so one WTBB1168 works on a left hand or a right hand door. Handing only becomes a factor if you add an electric modification, since the wire exits the hinge at a fixed location, so state the door hand when you order EMN, ETW, or ETM.
8) How many hinges do I need per door, and how far up the frame do they go?
Hinge count follows door height and weight, not the hinge model: three per leaf is the normal commercial count on a 7 foot door, with a fourth added on taller or heavier leaves. Hager publishes a standard hinge locations sheet giving the dimensions from the head and the sill for two, three, and four hinge openings, and that is the sheet to mark from. Because the WTBB1168 is a heavy weight hinge, do not drop to two per leaf on a heavy door to save money.
9) Is the pin removable, and can the door be lifted off from the secure side?
The WTBB1168 uses a non rising removable pin with a button tip and plug, so you can pull the pin and take the door down for service without unscrewing the leaves. That also means the pin is accessible from whichever side the barrel faces. On an out swinging exterior door where the hinge barrel is on the outside, add a security stud or a non removable pin option so the door cannot be lifted off.
10) What is the WTBB1168 hinge made of, and will steel hold up on an exterior door?
Steel leaves with a steel pin. Steel is the standard commercial substrate for interior openings and for exterior doors under cover, but on a coastal, pool, or wash down opening you want stainless instead. In that case look at a stainless hinge such as the Don-Jo BB94545 or the BEST CB223 stainless concealed bearing heavy weight hinge.
11) Ball bearing or concealed bearing hinge, which should I specify?
The WTBB1168 is a ball bearing hinge: the bearings sit in visible races between the knuckles, four of them on this model, and it is the long standing commercial standard for heavy doors. Concealed bearing hinges hide the bearing inside the barrel for a cleaner look on the same duty rating, and ZenSupply carries those in the Stanley Security CB199 heavy weight and the BEST CB223 stainless heavy weight. Function is comparable at the same duty level, so the choice is appearance and what the spec on the drawing calls out.
12) What finish does the Hager WTBB1168 come in, and will it match the rest of my hardware?
619 satin nickel. That is the BHMA finish code, so it matches lever sets, closers, and exit devices specified in 619 across the same opening. If your building standard is 630 satin stainless or 652 satin chrome, 619 sits close in tone but is not an exact match, and on a lobby opening the difference will show.
13) I have an existing electrified hinge from another manufacturer. Is there a Hager equivalent?
Hager publishes a commercial hinge cross reference that maps competitor hinge model numbers to the matching Hager part, and that is the document to use when you are matching an existing opening. For an electrified through wire hinge specifically, ZenSupply also carries the ACSI 5BB1, an Ives pattern 5 knuckle ball bearing full mortise hinge in 4-1/2 x 4-1/2 with a concealed 4 wire 28 gauge through wire. Note that the ACSI is a square 4-1/2 x 4-1/2, so it does not give you the extra throw the WTBB1168 does.
14) Concealed bearing or ball bearing - how does the Dormakaba CB199 differ from the Hager WTBB1168?
Both are heavy duty full mortise hinges. The Stanley Security CB199 is a full mortise concealed bearing heavy weight hinge in the Architectural Hinges series, where the bearings sit inside the knuckle line for a smooth uninterrupted barrel. The Hager WTBB1168 uses a ball bearing arrangement with a visible five knuckle barrel and is a wide throw hinge. Choose on appearance and clearance: concealed bearing for a clean barrel profile, the WTBB1168 where the door has to swing past deep trim.
15) Can the BEST 1900R be used in place of the Hager WTBB1168 on an interior office door?
The BEST 1900R is a steel full mortise concealed bearing standard weight hinge with a removable pin, rated medium duty in the Architectural Hinges series. It shares the removable pin arrangement with the Hager WTBB1168, which uses a non-rising removable pin with button tip and plug, and both are steel full mortise hinges. The 1900R is a standard weight, standard throw hinge for a lighter interior leaf; the WTBB1168 is heavy duty and wide throw for a heavier door or one needing extra swing clearance. Match the hinge to the door weight and the trim condition rather than treating the two as interchangeable.
16) How do the Don-Jo BB84545 and BB94545 compare with the Hager WTBB1168 for a corrosive or exterior opening?
The Don-Jo BB84545 is a 4-1/2 inch by 4-1/2 inch brass full mortise ball bearing hinge in satin chrome and the BB94545 is the same size in stainless steel with a square corner, both rated standard duty. Brass and stainless resist corrosion better than a steel-bodied hinge, which is the trade against the Hager WTBB1168, a steel heavy duty hinge. Neither Don-Jo is a wide throw hinge, so on an exterior door that also needs the leaf to clear deep trim, the substitution changes the swing geometry as well as the material.
17) If a facility is standardizing on 4-1/2 inch by 4-1/2 inch McKinney hinges, which McKinney matches the duty level of the Hager WTBB1168?
The McKinney TCA3386 is the heavy duty one: a square corner 5 knuckle full mortise hinge, 4-1/2 inch by 4-1/2 inch, heavy weight. The TCA2314 and TCA2317 are the same square corner 5 knuckle full mortise pattern in 4-1/2 inch by 4-1/2 inch but rated standard duty, which puts them a tier below the heavy duty Hager WTBB1168. For a facility standard that has to cover heavy commercial leaves on high frequency service, the TCA3386 is the McKinney to carry.
18) Is the Stanley Security CB1960R the same class of hinge as the Hager WTBB1168?
No. The Stanley Security CB1960R is a full mortise concealed bearing standard weight hinge, medium duty, in the Architectural Hinges series. The Hager WTBB1168 is a heavy duty ball bearing wide throw hinge with 5 knuckles, certified to ANSI A8111 for commercial use. They share the full mortise prep, so the frame cutout family is the same, but the CB1960R is a standard weight concealed bearing hinge and does not provide the wide throw projection or the heavy weight rating.
19) Are these hinges sold individually or by the box?
Hager packs the WTBB1168 three to a box and 24 to a case. Three per box lines up with one standard commercial door, so a box covers a single opening and a case covers eight doors on the same standard.
