BEST BEST-CERDFBB179-54-652-4.5x4.5 – Frequently Asked Questions

1) Is 4 wires enough for an electric strike or electrified lock, or do I need more conductors?
The BEST CERDFBB179-54 carries four concealed conductors, which covers a simple two-wire power run to an electric strike or electrified lock plus a spare pair, or power plus a single monitoring circuit. If you need door position switch, request-to-exit, latch monitoring and a motor-driven lock all on one opening, step up to the 6, 8 or 10 wire versions of the same hinge. Count your conductors on the lock's wiring sheet before you pick the suffix, since the hinge is mortised in and swapping later means re-pulling wire.
2) What door and frame prep does this BEST electrified hinge need?
It is a full mortise hinge with 1/4 inch radius corners, so both the door edge and the frame rabbet need mortised pockets routed with a 1/4 inch radius, the standard commercial hinge prep on hollow metal frames and factory-prepped wood doors. If your existing openings are cut square corner, the leaf will not seat correctly. Beyond the mortise you also need a route for the concealed conductor out of the frame pocket to a junction box.
3) Which hinge sizes does the CERDFBB179-54 come in, and which one matches my existing hinges?
Five sizes are offered: 4 x 4, 4.5 x 4, 4.5 x 4.5, 4.5 x 5, and 5 x 4 inches. Measure the leaf height and the open width of the hinge you are pulling off the door and match both numbers, because the mortise is already cut to that leaf height. On typical commercial hollow metal openings 4.5 x 4.5 is the usual size.
4) Do I replace all three hinges on the door with electrified ones?
No. Only one electrified hinge goes on the opening, and it mounts in the center hinge location. The top and bottom stay as your standard non-electric ball bearing hinges of the same size and finish, so order one CERDFBB179-54 plus matching plain hinges for the rest of the leaf.
5) Can I swap a Detex or RCI electric hinge out for this BEST one?
Judge it on size, wire count and prep rather than brand. The Detex EWH8 Series five knuckle electric hinge listed at 4.5 x 4.5 inches carries 8 wires, and the RCI 952 is a 6-conductor ball bearing hinge, so replacing either with the 4-wire CERDFBB179-54 leaves you short of conductors if the existing lock actually used them. The Design Hardware ETW2-BB5 at 4.5 x 4.5 is the closest match in size and medium duty class. Where the mortise is already 4.5 x 4.5 with 1/4 inch radius corners, the BEST hinge drops into that pocket; count the wires in the frame first.
6) What is a close equivalent to the BEST CERDFBB179-54 electrified hinge in 4.5 x 4.5 size?
The Design Hardware ETW2-BB5 is an electrified standard weight ball bearing hinge in 4.5 inch by 4.5 inch, rated medium duty - the same duty level and bearing arrangement as the BEST CERDFBB179-54, which is a standard weight ball bearing electrified hinge also offered in 4.5 inch by 4.5 inch. Differences to confirm before ordering: the BEST hinge carries a 4-wire concealed conductor and 1/4 inch radius corners, and BEST offers finishes from primed for painting through bright brass, satin bronze and satin chrome.
7) I need more than four conductors through the hinge - what should I use instead?
The BEST CERDFBB179-54 carries four wires. When the access control device needs more circuits, the RCI 952 electrified hinge runs 6 conductors and is also a medium duty ball bearing hinge, and the Detex EWH8 five knuckle electric hinge runs 8 wires in 4.5 inch by 4.5 inch with a satin chrome finish. Count your circuits - a mortise electric lock plus a request-to-exit switch and a door position switch will typically exceed four.
8) For a high-traffic entrance, is there a heavier-rated electric hinge than the BEST CERDFBB179-54?
The BEST CERDFBB179-54 is a standard weight, medium duty steel hinge with five knuckles, sized for typical commercial interior and light exterior openings. For heavier cycle demand, the SDC PTH Series electrified power transfer hinges carry an 800,000 cycle rating, and the Securitron EH is a double duty electric hinge. On a stairwell or main entry that sees constant use, spec by door weight and cycle count rather than by wire count alone.
9) Is this electrified hinge heavy duty enough for a high-traffic entrance door?
It is rated medium duty, standard weight steel with five knuckles and ball bearings. That suits interior commercial office, classroom, tenant and mechanical-room doors. For a heavy exterior entrance, a wide lead-lined door, or an opening on an aggressive closer, specify a heavy weight electrified hinge instead. Among other brands we carry, the SDC PTH Series power transfer hinges are published with an 800,000 cycle rating if cycle life is your deciding factor.
10) Should I use an electrified hinge or a door loop / electric power transfer for running power to a lock?
Use the concealed conductor hinge when the wiring must not be visible or reachable. No electrical parts are exposed once the hinge is installed, and it carries current to the lock, exit device or hold open device regardless of door position, which is what you want on a detention-adjacent, vandal-prone or public corridor opening. A surface door loop is easier to retrofit because it needs no mortise routing, but it is exposed on the hinge edge and can be cut. If the door and frame are already mortised for standard 1/4 inch radius hinges, the electrified hinge is the cleaner install.
11) What comes in the box, and what else do I need to buy to finish the job?
Each hinge is packed one per box with the concealed conductor, all machine screws and installation instructions. You supply the rest: the low-voltage cable from the frame to the power supply or access control panel, a junction box at the frame (the maker recommends one for the connections), your power supply, and the two matching non-electric hinges for the top and bottom of the leaf.
12) Is the Detex EWH8 a drop-in substitute for the BEST CERDFBB179-54?
Not without checking two things. The Detex EWH8 is a five knuckle electric hinge in 4.5 inch by 4.5 inch, matching the BEST CERDFBB179-54's five knuckle build and one of its sizes, but it is an 8 wire hinge where the BEST is 4 wire, and it is listed in satin chrome only. The BEST CERDFBB179-54 is offered in primed for painting, bright brass, satin brass, satin bronze, dark satin bronze, bright chrome and satin chrome, so if the opening's other hinges are bronze the Detex will not match visually.
13) Which electrified hinge should I pick if I am wiring a mortise electric lock and want nothing exposed?
The BEST CERDFBB179-54 uses a concealed conductor with no electrical parts exposed once installed, which suits tamper-sensitive openings feeding electric locks, exit devices or hold-open devices, and it is a full mortise ball bearing hinge in medium duty. The comparable power transfer options include the SDC PTH Series and the Securitron EH double duty electric hinge; both are hinge-based transfers as well, so the deciding factors are conductor count and the duty rating your door weight calls for.
14) What finishes does the BEST CERDFBB179-54 come in to match the rest of my door hardware?
Seven: 600 primed for painting, 632 bright brass, 633 satin brass, 639 satin bronze, 640 dark satin bronze, 651 bright chrome and 652 satin chrome, all on steel. All seven are available in every one of the five hinge sizes. For a facility standardized on 626 satin chromium, 652 satin chrome is the steel-base equivalent to spec here; the 600 primed option is the one to use when the hinge gets painted out with the frame.
15) Does this hinge have a removable pin, and will it stay put on an out-swinging exterior door?
The CERDFBB179-54 uses a permanent fast pin, so the pin is not designed to be pulled and the leaves do not separate for service the way a loose-pin hinge does. That works in your favour on security openings, since the door cannot be lifted off by drifting the pin, but it does mean the door comes off by unscrewing the leaf rather than tapping the pin out.
