BEST BEST-CERDFBB179-58-652-4.5x4 – Frequently Asked Questions

1) How many wires does the BEST CERDFBB179-58 electrified hinge carry, and is that enough for a card reader plus an electric lock?
Eight conductors run through the CERDFBB179-58. That gives you enough separate circuits to power an electric lock or exit device and still carry signal back from a reader or request-to-exit switch on the door leaf. If you only need power to a single electric strike or mag lock, a 6-conductor hinge such as the RCI 952 covers it; the 8-wire version is what you order when the door has both power and monitoring going through it.
2) What size and finish does the BEST CERDFBB179-58 electrified hinge come in?
It is supplied 4.5 x 4 inches in 652 satin chrome over steel. That is a standard commercial leaf size for a 1-3/4 inch door, but note the 4 inch width rather than 4.5 x 4.5 - if the existing hinge pocket on the door and frame is routed for a 4.5 x 4.5 leaf you will have filler to deal with. For a true 4.5 x 4.5 electrified swap, the Detex EWH8 8-wire hinge in satin chrome is that size.
3) Do I mount the electrified hinge at the top, middle, or bottom of the door?
Center hinge position. The CERDFBB179-58 is installed in the middle hinge location so the concealed conductor lands where the wire raceway in the door and frame is prepped, and it needs a junction box at the frame side for the terminations. The top and bottom hinges stay standard non-electrified hinges of the same size and finish.
4) Will this hinge handle a high-traffic entrance, or do I need a heavy weight hinge?
The CERDFBB179-58 is a standard weight, medium duty hinge with a five knuckle ball bearing barrel. That suits normal commercial interior and office openings with an average size, average frequency door. For heavy or oversized doors, or very high cycle entries, step up to a heavy weight electrified hinge - the Securitron EH is sold as a double duty electric hinge, and the SDC PTH series power transfer hinges carry an 800,000 cycle rating.
5) Does the corner style on this BEST hinge matter for my frame?
Yes, and it is the thing people get wrong. This one has 1/4 inch radius corners, which matches a hinge pocket routed by a template machine - the common commercial hollow metal and machined wood prep. If your existing pocket has square corners, the radius leaf will leave gaps at the corners and the screw pattern may not line up cleanly. Check the routed pocket in the frame before ordering.
6) What is the closest equivalent to the BEST CERDFBB179-58 if I need another 8-wire electrified hinge in satin chrome?
The Detex EWH8 is the nearest match. Detex's five knuckle electric hinge is a 4.5 inch by 4.5 inch 8-wire hinge in a satin chrome finish, and the BEST CERDFBB179-58 is a 5-knuckle ball bearing electrified hinge carrying 8 wires, offered in 4.5 inch by 4.5 inch with a 652 satin chrome steel finish. Both give you the same eight conductors, so a device wiring run planned around one drops onto the other without re-pulling conductors. The BEST unit is a full mortise ball bearing hinge with 1/4 inch radius corners, so confirm your door and frame are prepped for radius corners rather than square before you swap.
7) My access control device only needs six conductors. Is there a smaller-wire electrified hinge instead of the 8-wire BEST CERDFBB179-58?
Yes. The RCI 952 electrified hinge uses 6-conductor wiring with ball bearing construction and is a medium duty hinge, which covers a single electric lock or strike plus a monitoring contact without the two spare conductors. The BEST CERDFBB179-58 carries 8 wires and is also medium duty with ball bearings, so it suits openings where you want extra conductors in reserve for a future request-to-exit or door position switch. If the head-end panel and device count are already fixed at six, the RCI 952 matches that run; if the opening may gain a device later, the extra pair on the BEST hinge saves pulling the door again.
8) Is the wiring exposed once this hinge is installed?
No. The conductors are concealed inside the hinge, so with the door closed there is nothing exposed to cut or pull at, which is why concealed conductor hinges get specified over surface door loops on secure openings. It is a full mortise hinge, so both leaves sit in routed pockets in the door and frame.
9) What comes in the box with the BEST CERDFBB179-58 hinge?
The hinge ships with its concealed conductor, all machine screws, and installation instructions. What is not included and what you still need to source: the junction box for the frame-side terminations, the wire raceway prep in the door and frame, the power supply, and the electric lock, exit device or hold open device the hinge feeds.
10) Does the power stay on while the door is swinging open?
Yes. The conductor passes current regardless of door position, so an electric mortise lock, electrified exit device, or electromagnetic hold open stays energized and any monitoring circuit stays continuous through the full swing. The permanent fast pin keeps the barrel assembled so the wire path is not disturbed in service.
11) Can I get this electrified hinge with hospital tips for a healthcare corridor?
It can be furnished with hospital tips, which is what behavioral health and patient care corridors call for so nothing can be looped over the hinge tip. Specify the hospital tip option at time of order rather than assuming the standard hinge ships that way.
12) What are the alternatives if I just need power transfer to a lock and not eight conductors?
For plain power to an electrified lockset, a standard weight electrified ball bearing hinge is enough - the Design Hardware ETW2-BB5 is a 4.5 x 4.5 medium duty electrified ball bearing hinge, and the RCI 952 is a medium duty ball bearing electrified hinge with 6 conductors. Choose the BEST CERDFBB179-58 8-wire instead when the opening also has reader, monitoring, or request-to-exit circuits crossing the hinge, or when you want spare conductors for later access control work.
13) For a high-cycle opening, is there a power transfer hinge with a published cycle rating instead of the BEST CERDFBB179-58?
The SDC PTH Series electrified power transfer hinges carry an 800,000 cycle rating, which is the figure to hand a facilities spec that calls out cycle life on an entry, stairwell, or main corridor door. The BEST CERDFBB179-58 is a medium duty commercial electrified hinge with ball bearings and a 5-knuckle full mortise body. Where the drawing states a cycle count, the SDC PTH answers it directly; where the requirement is simply a commercial ball bearing hinge passing 8 conductors, the BEST unit covers it.
14) What should I use on a heavier door than the medium duty BEST CERDFBB179-58 handles?
Look at the Securitron EH Double Duty electric hinge from the EH Series, which is built as a double duty electric hinge for heavier leaf weight. The BEST CERDFBB179-58 is a medium duty standard weight steel full mortise hinge with ball bearings. On a standard-weight commercial door with an electric lock or exit device, the BEST hinge is the right class; on a heavy mineral-core or oversized leaf, step up to the Securitron EH.
15) Can I use a Design Hardware ETW2-BB5 in place of the BEST CERDFBB179-58?
They are close in class but not the same wire count. The Design Hardware ETW2-BB5 is a 4.5 inch by 4.5 inch electrified standard weight ball bearing hinge in the BB5 Series, rated medium duty. The BEST CERDFBB179-58 is also a medium duty ball bearing electrified hinge, and it carries an 8-wire concealed conductor with 1/4 inch radius corners in a 652 satin chrome steel finish at 4.5 inch by 4.5 inch. Match the conductor count your device schedule requires before substituting, and confirm the corner style matches the existing frame prep.
16) Where do I find the wiring diagram and hinge sizing information for the BEST FBB179 electrified hinge?
BEST publishes a dedicated electrified hinge catalog for the FBB179, a general hinge information sheet, a hinge size chart for matching leaf size to door width and thickness, and a hinge installation guide. All four are posted as PDFs alongside the product and are worth pulling before you cut the frame prep, since the conductor routing and junction box location come off those drawings.
17) Is a power transfer hinge the same thing as the BEST CERDFBB179-58 concealed conductor hinge?
They serve the same purpose but are described differently and should be checked before you order one for the other. The SDC PTH Series is sold as an electrified power transfer hinge, while the BEST CERDFBB179-58 is a full mortise ball bearing hinge with the 8-wire conductor concealed inside the hinge body so no wiring is exposed when installed. Both move current from frame to door; what differs is the hinge body and prep each one needs, so confirm the door and frame prep and the conductor count against the device schedule rather than assuming one drops in for the other.
