Command Access ETH4W4545 626 CH-CB70 – Frequently Asked Questions

1) What hinge sizes does the Command Access ETH-CB70 come in?
Four sizes: 4.5 x 4 inch, 4.5 x 4.5 inch, 4.5 x 5 inch and 5 x 5 inch. Match the size to the hinge already in the door and frame prep so you are not re-morticing anything. 4.5 x 4.5 is the common commercial opening; the 4.5 x 5 and 5 x 5 leaves are for thicker or wider doors where you need more leaf on the face.
2) Is the ETH-CB70 heavy enough for a high-traffic entrance door?
The ETH-CB70 is a standard weight, 3 knuckle hinge rated medium duty, which puts it on normal commercial doors rather than oversized or abused ones. For a heavy or high-frequency entrance, look at a heavy duty hinge instead: the Ives 3CB1HW is a steel heavy weight concealed bearing full mortise hinge with 3 knuckles, and BEST CB1969R is a concealed bearing heavy weight pivot-reinforced hinge. Note those are not electrified, so if the door also needs power transfer you will be adding a separate transfer device.
3) Will one energy transfer hinge power the whole door, or do I need all three hinges electrified?
One ETH-CB70 per opening does the power transfer. It carries the low voltage from the hinge jamb to the door-mounted device, so the other hinges on the leaf stay standard. Match the remaining hinges in size and finish, for example a medium duty steel 3 knuckle concealed bearing hinge like the Ives 3CB1, so the opening looks and hangs consistently.
4) What is the closest electrified hinge equivalent to the Command Access ETH-CB70?
The BEST CECB179-12C is the nearest match. It is a steel full mortise concealed bearing electrified hinge with a 12-wire quick connect, and it carries the same medium duty rating as the ETH-CB70. The difference is in how the wire count is chosen: the CECB179-12C is a fixed 12-wire part, while the ETH-CB70 is ordered by wire size option across 2W through 12W and their heavy-gauge WH variants such as 2WH (2/18ga) and 12WH (2/20ga+10/28ga). If the opening needs fewer conductors than twelve, the ETH-CB70 lets you specify them.
5) Is there a heavier-duty concealed conductor hinge than the ETH-CB70 for a high-traffic exterior door?
Yes. The Stanley Security CECB1900R54L is a three knuckle concealed bearing concealed conductor architectural hinge in steel full mortise, standard weight, 4-1/2 by 4-1/2 square corner, left-handed, 4-wire, and it is rated heavy duty. The ETH-CB70 is medium duty and also uses a 3 knuckle steel base design, offered in 4.5 x 4.5 among its sizes. Note the Stanley part is handed and fixed at four wires, so it suits a known opening with a light conductor count rather than a flexible spec.
6) If the door has no electrified hardware, what standard hinge matches the ETH-CB70's build?
The Ives 3CB1 is the mechanical counterpart in the same format: a steel 3-knuckle concealed bearing full mortise hinge with a medium duty rating, matching the ETH-CB70's 3 knuckle steel base construction and medium duty level. The 3CB1 carries no conductors, so it is the hinge to use on the two non-current-carrying positions of a door where only one hinge needs to transfer power.
7) Do I need an energy transfer hinge or a door loop for powering an electric lock?
An energy transfer hinge like the ETH-CB70 routes the low voltage through the hinge knuckles, so nothing is visible between frame and door. A surface door loop does the same job but leaves the cable exposed on the face of the opening, where it can be cut or pulled. If the opening is public-facing or you are running access control on it, the concealed hinge is the cleaner and more secure route. The tradeoff is that the hinge has to be the correct size and finish for the existing prep, while a loop fits almost anything.
8) What finishes does the ETH-CB70 energy transfer hinge come in to match the rest of my door hardware?
Ten finishes: 600 primed for painting, 605 bright brass, 606 satin brass, 609 antique brass, 612 satin bronze, 613 satin bronze oil-rubbed, 619 satin nickel, 625 bright chrome, 626 satin chrome and 693 black. Those are standard BHMA finish numbers, so 626 satin chrome will sit alongside 626 levers and closers on the same opening, and 600 lets you paint the hinge to the frame color.
9) What door devices can the Command Access ETH-CB70 feed power to?
Electric mortise locks, electric cylindrical locks, electric strikes, electric exit device trim, latch pullback devices, door mounted card readers and low voltage door lights. If the device sits on the door leaf and runs on low voltage, this hinge is how the power gets to it without a visible cable.
10) Is the ETH-CB70 a full mortise hinge that drops into a standard frame prep?
It is a standard weight steel base hinge in standard commercial leaf sizes (4.5 x 4, 4.5 x 4.5, 4.5 x 5 and 5 x 5), so it is ordered to match the existing hinge prep on the door and frame. The electrification is inside the knuckles rather than added to the leaf, so the hinge itself seats like a conventional one. What you do have to add is the wire raceway: the frame needs a path back to the power supply and the door needs a path from the hinge to the device.
11) Can a Hager 920 concealed bearing hinge substitute for the ETH-CB70?
Only mechanically. The Hager 920 is a full mortise concealed plain bearing hinge in 2 knuckle steel construction with a medium duty rating, so it shares the duty level with the ETH-CB70 but has a 2 knuckle barrel rather than 3, and it carries no conductors. The ETH-CB70 is an electronic hinge that routes low voltage power through the knuckles to electric mortise and cylindrical locks, electric strikes, exit trims, card readers and similar door-mounted devices. If the opening needs power at the door, the 920 will not do the job.
12) Is a ball bearing commercial hinge like the Orca 3535 interchangeable with the ETH-CB70?
They are not interchangeable in function. The Orca Hardware 3535 Series is a 4-1/2 by 4-1/2 square corner ball bearing commercial hinge rated medium duty, a purely mechanical hinge. The ETH-CB70 is an electrified hinge and is also available in a 4.5 x 4.5 size, so the two can sit in the same mortise prep on a door, but only the ETH-CB70 passes low voltage power. A common approach is the electrified hinge in one position and a mechanical hinge such as the 3535 in the others.
13) What is the difference between the ETH-CB70 and a security hinge like the Hager BB1168 NRP?
They solve different problems. The Hager BB1168 is a non-removable pin full mortise ball bearing hinge rated heavy duty, built to stop pin removal on an outswinging exterior door. The ETH-CB70 is a medium duty 3 knuckle steel base hinge whose purpose is concealed low voltage power transfer to door-mounted access control devices. On a secured outswing opening with electrified hardware, buyers often use both: the electrified hinge in one position and NRP hinges elsewhere.
14) Can I use the Command Access ETH-CB70 on a residential interior door?
It is built for commercial openings running access control, not for residential interior doors. For a house, a plain steel residential hinge such as the Delaney 3-1/2 x 3-1/2 interior residential hinge or the Emtek 91013 residential plain bearing hinge is the right part, and neither carries wire. Only go to an energy transfer hinge if you actually have a powered lock, strike, or reader on the leaf.
15) Would a 5-knuckle standard weight hinge such as the McKinney MP79 work in place of the ETH-CB70?
Not for an electrified opening. The McKinney MP79 MacPro is a full mortise 5-knuckle standard weight hinge rated standard duty, while the ETH-CB70 is a 3 knuckle hinge carrying low voltage conductors in wire counts from 2W up to 12W. The knuckle counts differ and the MP79 has no wire path, so it is a substitute only where no power needs to reach the door.
16) Are residential hinges like the Deltana DSB45 or Emtek 94013 an option for a door with a card reader?
No. The Deltana CSB45N is a 4-1/2 by 4-1/2 square hinge pair with non-removable pin, and the Emtek 94013 is a heavy duty ball bearing hinge pair at 3-1/2 by 3-1/2 with square corners; both are mechanical hinges sold in pairs for residential and light commercial openings. A door-mounted card reader needs power at the leaf, which is what the ETH-CB70 provides by routing low voltage through the hinge knuckles on a commercial rated assembly.
