BEST BEST-CSFBB179LH-652-4x4 – Frequently Asked Questions

1) What size hinges does the BEST CSFBB179 electrified hinge come in?
The CSFBB179 is offered in six sizes: 4 x 4, 4.5 x 4, 4.5 x 4.5, 4.5 x 5, 5 x 4, and 5 x 5 inches, all with square corners. Size the hinge to what is already mortised in the door and frame, since this is a full mortise hinge and it drops into a standard mortise pocket rather than a surface prep. 4.5 x 4.5 is the common commercial size and is also what the Design Hardware ETW2-BB5 and the Detex EWH8 electric hinge are built in, so if you are matching an existing opening that is usually the one to pull.
2) Do I have to order the BEST CSFBB179 hinge left hand or right hand?
Handing matters. The CSFBB179 is built left-handed or right-handed and there is no reversible option, so determine the door's hand before ordering. The switch is wired into one leaf, which is why the hinge is handed at all, unlike a plain ball bearing hinge you can flip. Stand outside the opening, on the side the door swings away from: hinges on your left is a left hand door, hinges on your right is a right hand door.
3) What does the concealed switch in the BEST CSFBB179 hinge actually do?
It monitors the door. The CS concealed switch is a single pole double throw switch that operates whether the door is open or closed, so it can signal position to an alarm panel, an access control head end, or any monitoring device wired to it. Because it lives inside the hinge, nothing electrical is exposed once the hinge is mortised in, which is the reason integrators use it over a surface door contact that can be picked at or defeated. It is the monitoring point, not a power transfer for a lock.
4) Can I use the BEST CSFBB179 hinge to power an electrified lock or exit device?
No, and this is the most common mix-up on electric hinges. The CSFBB179 carries a concealed monitoring switch only, a single pole double throw contact for door position. It has no conductor bundle for running power through the door to a lock, strike, or exit device. If you need to energize hardware in the door leaf, look at a power transfer hinge instead: the Detex EWH8 five knuckle electric hinge is an 8 wire, the RCI 952 is a 6-conductor ball bearing electrified hinge, and SDC's PTH Series is a power transfer hinge. Plenty of jobs use both, one hinge for transfer and this one for monitoring.
5) Which hinge position should the electrified BEST CSFBB179 go in on the door?
Center hinge location. The CSFBB179 is meant to be installed as the middle hinge on the opening, with standard ball bearing hinges above and below carrying the door. That keeps the switch away from the top and bottom of the leaf where the door flexes most and puts the wire run at a convenient height for routing back through the frame. So on a typical three-hinge commercial door you buy one CSFBB179 and two matching plain hinges, not three electrified units.
6) What is the difference between a concealed switch hinge and an electric power transfer hinge?
They do different jobs. The BEST CSFBB179 carries a concealed switch that monitors whether the door is open or closed, and no electrical parts are exposed once the hinge is installed. A power transfer hinge instead carries conductors through the hinge to feed a device in the door, such as an electric lock; the SDC PTH Series is a power transfer hinge, and the Detex EWH8 is a five knuckle electric hinge with 8 wire, while the RCI 952 uses 6-conductor wiring. If the job is to power a lock in the door leaf, a wired transfer hinge is the part; if the job is to signal door position to an alarm or access control panel, the switch hinge is.
7) I need to both monitor the door and power an electric lock in the leaf. What do I use?
The BEST CSFBB179 provides monitoring through its concealed switch, which operates with the door open or closed, but it is a switch hinge rather than a conductor hinge. To carry current to a device mounted in the door, use a wired transfer hinge such as the RCI 952, which has 6-conductor wiring and ball bearing construction, or the Detex EWH8 with 8 wire. Many openings use one of each in different hinge positions, and the CSFBB179 is designed for the center hinge location.
8) Is the BEST CSFBB179 hinge heavy enough for a high traffic commercial door?
It is a standard weight, medium duty steel hinge with five knuckles and ball bearings, built for commercial openings. That covers office, classroom, tenant suite, and interior corridor doors carried on three hinges. For a heavy leaf, a high frequency entrance, or a door hung on a closer that gets slammed all day, standard weight medium duty is the wrong pick and you want a heavy weight electrified hinge. Securitron's EH Double Duty electric hinge is the double duty option in the same category.
9) What finishes can I get the BEST CSFBB179 electrified hinge in to match the rest of my door hardware?
Eight finishes: 600 primed for painting, 632 bright brass, 633 satin brass, 639 satin bronze, 640 dark satin bronze, 641 oxidized bronze, 651 bright chrome, and 652 satin chrome, all on steel. For a building already standardized on 626 satin chrome trim, 652 satin chrome is the match on this steel hinge. The 600 primed option is the one to order when the hinges get painted out with the frame, which is common on back of house and stairwell openings where nobody is trying to match a lever.
10) What comes in the box with a BEST CSFBB179 hinge, and what else do I need to order?
Each CSFBB179 is packed one hinge per box with screws and installation instructions, and the concealed switch is built into the hinge. What is not in the box is the rest of the opening: you still need the two plain hinges that go above and below it, since this one mounts in the center position, plus your wire, connectors, and whatever monitoring panel or access control input the switch reports to. Order the hinge count per door accordingly, one electrified and two standard on a typical three-hinge leaf.
11) Should I use a concealed switch hinge or a surface mounted door contact for door position monitoring?
A concealed switch hinge like the BEST CSFBB179 hides the monitoring point inside the mortise, so no electrical parts are exposed once installed and there is nothing on the face of the door or frame to tamper with, pry, or magnet-spoof. A surface contact is faster to install and can go on any existing door without re-prepping a hinge pocket. Choose the hinge where the opening is security critical or public facing and you are already replacing hardware; choose a surface contact on a retrofit where you are not touching the hinges. The hinge switch is single pole double throw, so it gives you both a normally open and a normally closed leg off the same device.
12) What is a comparable electrified ball bearing hinge to the BEST CSFBB179 if I need a different brand?
For like-for-like medium duty electrified ball bearing hinges, the Design Hardware ETW2-BB5 is a 4.5 x 4.5 electrified standard weight ball bearing hinge rated medium duty, and the RCI 952 is a medium duty electrified hinge with ball bearing construction and 6-conductor wiring. Note the difference in what they do: the RCI 952 carries conductors through the door, while the BEST CSFBB179 carries a concealed monitoring switch. Match on function first, then on size and finish, since the CSFBB179 covers six sizes and eight finishes in both hands.
13) Which electrified hinge should I specify for a high traffic opening rather than a standard weight one?
The BEST CSFBB179 is a standard weight steel hinge rated medium duty, which suits typical commercial doors. For an opening cycling harder, the Securitron EH is a double duty electric hinge, and the SDC PTH Series is rated for 800,000 cycles. Note that those are wired hinges rather than switch hinges, so a door that also needs position monitoring would still take a concealed switch hinge in another hinge position.
14) Does the finish I need limit which electrified hinge I can order?
It can. The BEST CSFBB179 comes in eight finishes: 600 primed for painting, 632 bright brass, 633 satin brass, 639 satin bronze, 640 satin bronze dark, 641 oxidized bronze, 651 bright chrome and 652 satin chrome, so it can be matched to brass, bronze or chrome hardware already on the openings. The Detex EWH8 comparable is a satin chrome hinge. If a building standardizes on a bronze or brass finish, the CSFBB179 finish range covers those.
15) Do I need to specify handing on an electrified hinge?
Yes for the BEST CSFBB179 - it is ordered left-handed or right-handed, because the concealed switch is oriented to the door swing. A general electrified ball bearing hinge such as the Design Hardware ETW2-BB5 is a 4.5 inch by 4.5 inch standard weight ball bearing hinge, so when replacing one with a switch hinge, confirm the swing of the opening before ordering.
16) Is a five knuckle electric hinge the same thing as the BEST CSFBB179?
Not necessarily. The BEST CSFBB179 is a five knuckle full mortise ball bearing hinge with square corners, and the Detex EWH8 is also a five knuckle electric hinge at 4.5 inch by 4.5 inch, but the Detex is an 8 wire hinge while the BEST carries a concealed switch. Matching knuckle count and size does not mean the two do the same electrical job, so check whether the opening needs conductors or a monitoring contact.
17) I need door monitoring on a stairwell door, do I need a special electrified hinge or will a standard ball bearing hinge work?
A standard hinge gives you nothing electrical. If the opening has to report open or closed to an alarm or access control system and you want the monitoring point concealed, you need an electrified hinge such as the BEST CSFBB179, which is a full mortise steel ball bearing hinge with the switch built in. Physically it hangs the door like any other standard weight five knuckle hinge, so the door prep and operation are unchanged, and the ball bearings handle the same duty. The difference is entirely the switch and the wire run you have to plan for in the frame.
18) I am standardizing hinges across a healthcare facility, can I spec one BEST CSFBB179 part across different door sizes?
One model, yes, but you will be ordering multiple part configurations. The CSFBB179 is built in six sizes from 4 x 4 up to 5 x 5, in left and right hand, and in eight finishes, so a facility with mixed door widths and swings pulls several combinations of the same hinge. Keeping the finish constant across the building is the easy standardization win, and specifying square corner prep throughout means the mortise pockets are interchangeable size for size. The hinge is a commercial, medium duty steel unit, so it suits patient room, office, and corridor doors rather than heavy main entrances.
