Command Access ETH12WH4545 630 CH-BB91 – Frequently Asked Questions

1) How does the Command Access ETH energy transfer hinge get power from the frame into the door?
Power runs through the hinge itself. The ETH-BB91 carries low voltage conductors from the hinge jamb into the door so nothing is exposed between frame and door, and it looks like a standard 5 knuckle mortise hinge once installed. It feeds door mounted devices: electric mortise and cylindrical locks, electric strikes, electric exit trims, latch pullback devices, card readers mounted on the door, and low voltage door lights.
2) How many wires do I need in an energy transfer hinge for an electric lock and a card reader?
Count the conductors your devices need, then pick the matching wire option. The ETH-BB91 is built in 2W (2/20ga), 2WH (2/18ga), 4W (4/26ga), 4WH (2/18ga plus 2/26ga), 6W (6/26ga), 6WH (2/18ga plus 4/28ga), 8W (8/28ga), 8WH (2/20ga plus 6/28ga), 10W (10/28ga), 10WH (2/20ga plus 8/28ga), 12W (12/28ga) and 12WH (2/20ga plus 10/28ga). The H options pair two heavier gauge conductors with a bundle of smaller ones, which is what you want when one device draws current (an electric lock) and the other is signal only (a reader or a request-to-exit switch). Straight numbered options are all one gauge.
3) What size energy transfer hinge do I order to match the hinges already on my commercial door?
Order the ETH to match the existing hinge cutout, not the door. It comes in 4 x 4, 4-1/2 x 4, 4-1/2 x 4-1/2, 4-1/2 x 5 and 5 x 5 inch sizes, so the common commercial 4-1/2 x 4-1/2 mortise prep is covered and drops in with no frame or door rework. Measure an existing hinge leaf, height first, then the open width across both leaves.
4) Do I replace every hinge on the door with an energy transfer hinge?
No. One ETH-BB91 carries the power; the rest of the openings hinges stay conventional. Match the finish and size of the ETH to the others so the door reads consistently, which is why it is offered in 613 satin bronze oil-rubbed, 626 satin chrome, 629 bright stainless steel and 630 satin stainless steel across the 4 x 4 through 5 x 5 sizes. If the remaining hinges also need replacing, a standard weight 5 knuckle like the McKinney MP79 MacPro full mortise or the Stanley FBB191 in 4-1/2 x 4-1/2 covers the non-electrified positions.
5) Is a 5 knuckle standard weight electrified hinge strong enough for a heavy exterior or high traffic door?
The ETH-BB91 is a medium duty, standard weight 5 knuckle hinge in stainless steel, which suits normal commercial interior and light exterior openings. A heavy or oversized door, or one on a closer taking constant traffic, wants heavy weight hardware instead, and the electrified position would need a heavy weight equivalent rather than this one. For the non-electrified positions on such a door, heavy weight ball bearing hinges like the Don-Jo HWBB84545 in 4-1/2 x 4-1/2 or the Ives 3CB1HW are the class you are looking at.
6) What is the equivalent to the Command Access ETH-BB91 energy transfer hinge from BEST?
The BEST CECB179-12C is the closest peer: a steel full mortise concealed bearing electrified hinge with a 12-wire quick connect, and BEST rates it Medium Duty in its Electrified Hinges series. The Command Access ETH-BB91 is also a medium duty electrified hinge, built on a stainless steel base with a 5 knuckle standard weight body, and it is ordered by wire configuration rather than fixed at one count - options run from 2W (2/20ga) through 12W (12/28ga), plus heavy-lead variants such as 12WH (2/20ga+10/28ga). The BEST unit uses concealed bearings; the ETH-BB91 is a 5 knuckle standard weight design.
7) What should I use instead of a Command Access ETH-BB91 on a heavy traffic or high abuse opening?
The Command Access ETH-BB91 is a medium duty, standard weight hinge. Where the opening calls for a heavier body, the Ives 3CB1HW is a steel heavy weight concealed bearing full mortise hinge with 3 knuckles rated Heavy Duty, the Hager BB1168 is a non-removable pin full mortise ball bearing heavy duty hinge, and the Don-Jo HWBB84545 is a heavy weight full mortise ball bearing hinge, 4-1/2 inch by 4-1/2 inch, in satin chrome, also rated Heavy Duty. None of those three carry a power circuit through the hinge, so a powered lock or reader on the door would need its transfer handled another way.
8) Is a concealed bearing hinge like the Ives 3CB1 the same thing as a Command Access ETH-BB91?
No. The Ives 3CB1 is a steel 3-knuckle concealed bearing full mortise hinge with a medium duty rating - the concealed element is the bearing, not a conductor. The Command Access ETH-BB91 conceals low voltage wiring, routing power through the hinge pin assembly to electric mortise and cylindrical locks, electric strikes, electric exit trims, latch pullback devices, door mounted card readers, and low voltage door lights. Both are medium duty, but only the ETH-BB91 completes an electrical path across the opening. The Hager 920 is another concealed bearing hinge, a full mortise 2 knuckle steel medium duty unit, and it is likewise a mechanical hinge only.
9) Energy transfer hinge or an electric power transfer in the frame, which should I use?
An energy transfer hinge is the right call when you want no visible loop between frame and door and the opening already has a standard mortise hinge prep, since the ETH replaces one hinge in the existing cutout. Wiring runs up the frame to that hinge location and out into the door edge. A door loop or frame mounted transfer is the fallback when the hinge prep cannot be used or the conductor count outgrows the hinge, but it is visible at the hinge edge. On conductor count the ETH goes to 12 wires, so most access control jobs stay inside it.
10) Which finishes does the Command Access energy transfer hinge come in so it matches the rest of my door hardware?
Four: 613 satin bronze oil-rubbed, 626 satin chrome, 629 bright stainless steel and 630 satin stainless steel. On a building standardized to 626 chrome trim, the 626 hinge is the match; 630 is the usual pairing with satin stainless levers and push plates. Since only one hinge on the door is electrified, getting this finish right is what keeps the opening from looking patched.
11) What is the difference between the Command Access ETH and a quick connect electrified hinge like the BEST CECB179?
Both move low voltage through the hinge. The ETH-BB91 is a 5 knuckle standard weight stainless steel hinge with the wire count chosen at order time, anywhere from 2 to 12 conductors. The BEST CECB179-12C is a steel full mortise concealed bearing electrified hinge with a 12-wire quick connect, so it is fixed at 12 wires with a plug style termination instead of flying leads. Stanley also builds a concealed conductor version, the CECB1900R54L, a three knuckle concealed bearing hinge in 4-1/2 x 4-1/2 square corner, left handed, with 4 wires, which is handed and so must be ordered to the door swing.
12) What do I have to specify when ordering a Command Access ETH-BB91 energy transfer hinge?
Three things settle the order: size, finish and wire option. Size from 4 x 4, 4-1/2 x 4, 4-1/2 x 4-1/2, 4-1/2 x 5 or 5 x 5 inches to match the existing prep; finish from 613, 626, 629 or 630 to match the rest of the opening; and the conductor bundle, from 2W up to 12W, or one of the WH options that mixes heavier and lighter gauges for a mixed power and signal run. Get the wire count from the device schedule before you order, because a hinge with too few conductors cannot be added to later.
13) For a 4-1/2 by 4-1/2 commercial opening, what non-electrified hinge matches a Command Access ETH-BB91 in that size?
The Command Access ETH-BB91 covers 4.5 inch by 4.5 inch among its sizes. Peers in that footprint include the Orca Hardware 3535 Series, a 4-1/2 inch by 4-1/2 inch square corner ball bearing commercial hinge rated Medium Duty, which matches the ETH-BB91 duty level; the Stanley FBB191, a 5-knuckle full mortise standard weight hinge at 4.5 inch by 4.5 inch that Stanley rates Heavy Duty and which shares the 5 knuckle standard weight arrangement; and the Don-Jo HWBB74545, a heavy weight full mortise ball bearing hinge at 4-1/2 inch by 4-1/2 inch. None of them carry wiring through the hinge.
14) Can I use a residential hinge in place of a Command Access ETH-BB91?
The Command Access ETH-BB91 is a commercial electrified hinge in stainless steel, medium duty, ordered in sizes from 4 inch by 4 inch to 5 inch by 5 inch. Residential peers sit in a different class and carry no conductor: the Emtek 91013 is a residential plain bearing pair, 3-1/2 inch by 3-1/2 inch square corner plated steel; the Delaney RH35xx is a 3-1/2 inch by 3-1/2 inch bulk steel residential interior pair with a 5/8 inch radius; and the Schlage Residential S3P1010 is a 3.5 inch by 3.5 inch square corner plain bearing mortise hinge sold in packs of three. For a commercial opening without power, the Delaney CH401X is a 4 inch by 4 inch commercial ball bearing square corner hinge.
15) Will a Command Access ETH-BB91 work on a detention or prison opening?
The Command Access ETH-BB91 is a medium duty standard weight electrified hinge. Detention openings are served by a different class of hinge: the BEST BB855 is a heavy-duty steel double weight concealed ball bearing prison hinge in BEST's Detention Hardware series, the Stanley BB855 is a double weight prison hinge furnished with no holes and not swaged at 5 inch by 6 inch, and the Hager 990 STEEL is a full surface prison hinge, 3 inch by 4 inch, with a welded tip, heavy duty. All three are mechanical hinges without a power path, so a powered lock on a detention door needs its transfer solved separately.
16) What do I use instead of a Command Access ETH-BB91 on a door that swings both ways?
The Command Access ETH-BB91 is a full mortise style 5 knuckle standard weight energy transfer hinge for conventional single-swing commercial openings. A door that swings in both directions is hung on a pivot instead - the BEST DAP-3 is a heavy duty double acting pivot for commercial interior doors, in BEST's Emergency Rescue Hardware series. The BEST CB1969R is a concealed bearing heavy weight pivot-reinforced hinge, rated Heavy Duty. Neither pivot option carries low voltage through the hardware the way the ETH-BB91 does.
17) Which hinge should I specify if the door needs a security pin rather than a power transfer?
The Command Access ETH-BB91 addresses concealed low voltage power, not pin security. Where the concern is pulling the pin from the outswing side, the Hager BB1168 is a non-removable pin full mortise ball bearing heavy duty hinge, the Deltana CSB45N is a 4-1/2 inch by 4-1/2 inch square hinge pair with a non-removeable pin, and the Deltana DE44R5TA is a 4 inch by 4 inch, 5/8 inch radius security hinge pair in steel. If the same opening also needs power at the lock, the security hinge and the ETH-BB91 solve different halves of the problem and are commonly used together in one hinge set.
18) Is the Command Access ETH-BB91 available in the same finishes as other commercial hinges I would spec alongside it?
The Command Access ETH-BB91 is offered in 626 Satin Chrome, 630 Satin Stainless Steel, 629 Bright Stainless Steel, and 613 Satin Bronze Oil-Rubbed. That 626 option lines up with the satin chrome finish on Don-Jo's heavy weight ball bearing hinges, including the HWBB74545 at 4-1/2 inch by 4-1/2 inch, the HWBB75045 at 5 inch by 4-1/2 inch, and the brass-bodied HWBB85045 at 5 inch by 4-1/2 inch - useful when only one leaf in the set is the electrified one and the rest of the opening is standard hardware.
19) Can I use an energy transfer hinge on a residential interior door?
The ETH-BB91 is a commercial product built for electrified openings, and putting a 12 conductor stainless hinge on an interior bedroom door is money spent on nothing. For plain residential and light interior work, standard hinges are the right part: Emtek 91013 residential plain bearing 3-1/2 x 3-1/2 pairs, Deltana DSB35 3-1/2 x 3-1/2 square hinges, or Delaney 4 x 4 bulk residential hinges for exterior openings.
20) Do plain bearing commercial hinges like the Orca 4040 substitute for a Command Access ETH-BB91?
They substitute mechanically, not electrically. The Orca Hardware 4040 Series is a 4 inch by 4 inch square corner plain bearing commercial hinge rated Medium Duty, the Orca 4014 Series is the 4 inch by 4 inch version with a 1/4 inch radius corner, and the Hager 1129 is a half mortise plain bearing commercial hinge, 4-1/2 inch, standard weight steel. Each hangs a commercial door in a size the Command Access ETH-BB91 also covers, but none passes low voltage power from the jamb to the door, which is the reason the ETH-BB91 goes on the opening in the first place.
21) How does a spring hinge compare to a Command Access ETH-BB91 on an access controlled door?
The Stanley Security 2060R is a full mortise spring hinge, square corner, 4.5 inch by 4.5 inch on a ferrous steel base, rated Heavy Duty - its job is closing the door. The Command Access ETH-BB91 is a medium duty electrified hinge whose job is carrying low voltage to the lock, strike, exit trim, or card reader on the door. On an access controlled opening the two are complementary rather than alternative: the spring hinge returns the door, the ETH-BB91 powers what latches it.
