ACSI 5BB1-4.5X4.5-26D-1104 – Frequently Asked Questions

1) Will the ACSI 5BB1 electric hinge transfer power to an electric strike or electrified lock without a surface door loop?
That's the point of it. The 5BB1 is a full mortise hinge with a concealed through-wire running inside the barrel, so the current transfer to an electrified lock, electric strike, or exit device trim happens inside the hinge prep instead of through a surface-mounted door cord. Nothing shows on the face of the door or frame. Wire count is your choice at order time: 4-wire or 8-wire, at 28 gauge.
2) Should I order the 4-wire or the 8-wire version of the 5BB1 hinge?
Count the circuits crossing the door before you order. Each device you power or monitor at the door leaf needs its own pair, so a single electrified lock body is typically fine on 4-wire, while a lock plus a request-to-exit switch, a latch monitor, or a card reader head runs you out of conductors fast. Both builds are 28 gauge. This is a per-opening decision and it's not field-changeable, so get the count right on the hardware schedule.
3) Do I need to replace all three hinges on the door with the electric one?
No. One 5BB1 through-wire hinge carries the power on the opening; the other hinges in the same leaf stay standard. Common practice is to put the electrified hinge in the center or top position and match the remaining hinges in size and finish. Since it's 4-1/2 x 4-1/2 with square corners and full mortise prep, it drops into the same prep as the standard hinges beside it, so you're only cutting for the wire raceway, not re-morticing the door.
4) Will a 4-1/2 x 4-1/2 square corner hinge fit my existing hollow metal door prep?
Standard commercial hollow metal frames and doors are prepped for 4-1/2 x 4-1/2 square corner full mortise hinges, and that's exactly what the 5BB1 is. If your existing hinges measure 4-1/2 inches on both leaves and have square corners rather than a radius, the plate footprint matches. What is new is the wire: the door and frame need a raceway to the lock and to the transfer point in the frame, which is straightforward on a new prep and a retrofit item on an existing door.
5) Is the 5BB1 electric hinge heavy enough for a high traffic entrance door?
It's spec'd for medium-weight doors at medium-frequency use, so a main entrance, a stairwell on a busy floor, or any door cycling constantly is asking more of it than it's rated for. Two ball bearing assemblies across five knuckles handle office doors, suite entries, and controlled-access interior openings. For heavy doors or heavy traffic, look at a heavy weight hinge such as the McKinney TCA3386 in the same 4-1/2 by 4-1/2 square corner size, keeping in mind that's a standard hinge and you'd need a separate power transfer for the electrified hardware.
6) The ACSI 5BB1 is not ADA compliant. What hinge clears the opening width for an accessible door?
The ACSI 5BB1 is a standard full mortise hinge and is not ADA compliant. Where the opening has to gain clear width, a swing clear hinge moves the door fully out of the opening: the BEST CB248 is a steel full mortise concealed bearing swing clear hinge for square edge doors in a medium duty class, and the Hager 1260 is a full mortise swing clear hinge with a 5-knuckle plain bearing design in a heavy duty class. Neither swing clear model carries a through-wire, so an accessible electrified opening needs its power transfer handled elsewhere in the frame.
7) What is the closest non-electrified equivalent to the ACSI 5BB1 4-1/2 inch by 4-1/2 inch hinge for the doors on a project that do not need power transfer?
The Don-Jo BB84545 is a full mortise ball bearing hinge in 4-1/2 inch by 4-1/2 inch brass, matching the ACSI 5BB1's brass substrate, full mortise mount, and 4.5 inch by 4.5 inch size, but without the concealed through-wire. If the opening needs steel rather than brass at the same size and 5-knuckle square corner pattern, the Don-Jo BB74545 covers it. Both are standard duty. Use the 5BB1 only at the openings where an electrified lock or monitored device actually needs current through the hinge, and carry a plain ball bearing hinge everywhere else in the same finish family.
8) The ACSI 5BB1 is rated for medium-weight, medium-frequency doors. What hinge should be used on a heavy commercial entrance instead?
The ACSI 5BB1 is built for medium-weight doors in medium-frequency use. For a heavier opening, the McKinney TCA3386 is a heavy weight square corner 5 knuckle full mortise hinge in the same 4-1/2 inch by 4-1/2 inch size, so the door and frame prep carries over. The Dormakaba CB199 is a heavy weight full mortise concealed bearing hinge, and the BEST CB223 is a heavy weight concealed bearing pivot reinforced hinge for beveled edge doors. Note that none of those three carry a through-wire, so a heavy electrified opening needs a separate power transfer device in the frame.
9) What hinge should be used when the door has to clear trim or wall projection instead of the ACSI 5BB1?
The ACSI 5BB1 is a 4-1/2 inch by 4-1/2 inch full mortise hinge, which sets the door back at a standard throw. When the door has to swing past applied trim, deep casing, or a wall projection, a wide throw hinge is the answer: the Hager WTBB1168 is a 4-1/2 inch by 6 inch full mortise ball bearing wide throw hinge, heavy weight, with 5 knuckles. The extra leaf width carries the door further off the frame. It is a plain ball bearing hinge, so an electrified opening at that condition needs the power transfer handled separately.
10) Can the pin be pulled out of the 5BB1 hinge from the secure side?
The 5BB1 uses a non-removable pin, so the hinge can't be knocked apart with a punch to lift the door off. That matters on out-swinging doors where the barrel sits on the exterior, which is common on stairwells, mechanical rooms, and rear service entries. If you're specifying an out-swing opening under access control, the NRP construction is doing real work alongside whatever the electrified lock provides.
11) What finishes does the ACSI 5BB1 electric hinge come in, and will it match my other door hardware?
Three finishes, in both the 4-wire and 8-wire builds: 10A satin bronze blackened, 613 satin bronze oil-rubbed, and 626 satin chrome. 626 is the workhorse for commercial openings and matches most satin chrome levers, closers, and exit devices already in the field. 613 and 10A cover dark bronze schemes. Because the electrified hinge is one hinge in a set, spec the remaining standard hinges in the same finish so the opening reads consistently.
12) Is the ACSI 5BB1 hinge brass or steel, and does that matter for an exterior door?
Brass. That gives you corrosion resistance a plain steel hinge doesn't have, which is worth having on exterior and high-humidity openings like pool corridors, laundry rooms, and coastal buildings. If your specification calls for steel or stainless instead, the Don-Jo BB74545 is a steel 4-1/2 x 4-1/2 square corner 5-knuckle hinge and the Don-Jo BB94545 is the stainless version in the same size, though neither carries a through-wire.
13) Is the ACSI 5BB1 electric hinge UL Listed and does it meet ANSI/BHMA hinge standards?
UL Listed, and built to ANSI/BHMA A156.1 and A156.7. A156.1 is the butt hinge standard and A156.7 covers template hinge dimensions, which is what tells you the hole pattern lands where a templated commercial frame expects it. For an institutional submittal, that pairing is usually what the hardware schedule is asking for on a mortise hinge.
14) My schedule calls out 5BB1HW or FBB179. Is this the same hinge?
Those designations are how this hinge is written up in architectural hardware schedules, alongside plain 5BB1. If the schedule is asking for an electrified through-wire 5 knuckle ball bearing full mortise hinge at 4-1/2 x 4-1/2, this is the part that answers it. Confirm the wire count on the schedule, since 4-wire and 8-wire are separate orderable builds.
15) Ball bearing or plain bearing hinge for a commercial door with a closer on it?
Put a bearing hinge on anything with a door closer. A closer loads the hinge every cycle, and a plain bearing knuckle wears and starts to sag and bind under that. The 5BB1 carries two ball bearing assemblies across its five knuckles. Plain bearing hinges like the Hager 1279 or the Hager 1541 are for lighter, lower-cycle openings without a closer pulling on them.
16) Can a Hager 1279 or Hager 1541 be substituted for the ACSI 5BB1 electric hinge?
No. The Hager 1279 is a full mortise plain bearing commercial hinge with 5 knuckles and the Hager 1541 is a full mortise plain bearing residential hinge in stainless steel with a 5 knuckle design. Both are plain bearing and neither carries wiring, while the ACSI 5BB1 is a ball bearing hinge with a concealed 4-wire 28 gauge through-wire. Swapping either one into an electrified opening leaves the lock, strike, or monitoring device with no path for current, and plain bearing hinges are a different wear class than ball bearing under the same traffic.
17) The ACSI 5BB1 has a non-removable pin. What is a comparable hinge with a removable pin?
The BEST 1900R is a steel full mortise concealed bearing standard weight hinge with a removable pin, and the Stanley Security CB1960R is a full mortise concealed bearing standard weight hinge in the same medium duty class. Both are medium duty, matching the ACSI 5BB1's medium-weight application, but the 5BB1's pin is non-removable, which is what you want on an exterior or secure-side opening where the hinge is exposed. Choose the removable-pin models on interior openings where the leaf needs to come apart for door removal during turnover work.
18) What is the difference between the ACSI 5BB1 and the McKinney TCA2314 or TCA2317?
The McKinney TCA2314 and TCA2317 are both square corner 5 knuckle full mortise hinges at 4-1/2 inch by 4-1/2 inch in a standard duty class, so they share the ACSI 5BB1's square corner, 5 knuckle, full mortise pattern and its 4.5 inch by 4.5 inch size. The distinguishing feature of the 5BB1 is the concealed 4-wire 28 gauge through-wire for current transfer in access-controlled openings, plus its brass substrate. On an opening with no electrified hardware, the McKinney models drop into the same frame prep.
19) Is the ACSI 5BB1 the right hinge for a beveled edge door?
The ACSI 5BB1 is a square corner full mortise hinge. For a beveled edge door, the BEST CB223 is a stainless steel concealed bearing heavy weight pivot reinforced hinge built specifically for beveled edge doors. On square edge doors, the BEST FBB212 is a steel ball bearing heavy weight pivot reinforced hinge in a standard duty class. Confirm the door edge condition before ordering, because a hinge cut for one edge profile will not seat correctly on the other.
20) For standardizing hinges across a facility, how do concealed bearing hinges compare to the ACSI 5BB1 ball bearing hinge?
The ACSI 5BB1 is a 5 knuckle ball bearing hinge with two bearing assemblies and visible knuckle segmentation. The concealed bearing alternatives hide the bearing inside the barrel for a smoother knuckle line: the BEST 1900R and the Stanley Security CB1960R are both full mortise concealed bearing standard weight hinges in a medium duty class, and the Dormakaba CB199 is a heavy weight version. If a facility standard is being set, decide the bearing style once, because mixing concealed bearing and ball bearing hinges across a corridor gives a visibly different knuckle profile door to door even in a matched finish.
