PDQ 35SSBB-EL Electrified 2 Ball Bearing Hinge, Stainless Steel
PDQ EL Series Electrified Power Transfer Hinges
PDQ EL Series electrified hinges carry concealed wiring through the hinge knuckle, transferring power between the frame and the door for PDQ electrified locks, exit devices and trim. They are built on PDQ full mortise 2 ball bearing standard weight and 4 ball bearing heavy weight hinges in steel or stainless steel, and come standard with a non-removable pin.
The EL4 option carries 4 wires (two 20 gauge, two 26 gauge) for a single electrified function. The EL8 option carries 8 wires (28 gauge) to run multiple devices, such as a lock, a request-to-exit switch and a door position switch, through one hinge. ISMC versions of each add a Molex connector so installers can plug in leads instead of hard-wiring each conductor at the hinge.

Frequently Asked Questions
What is the difference between the EL4 and the EL8?
The EL4 has 4 internal wires for a single electrified device. The EL8 has 8 wires to run multiple devices, such as a lock plus a request-to-exit switch plus a door position switch, through one hinge.
Can an EL Series hinge be used on a fire-rated door?
PDQ states the EL4 and EL8 are UL listed and conform to NFPA 80-2010 Section 6.4.3.1 for fire door hardware, in addition to ANSI/BHMA A156.1-2013.
Is there a version with a plug-in connector?
Yes. The EL4-ISMC and EL8-ISMC options add a Molex connector, so lock or strike leads plug in at the hinge instead of being hard-wired.

PDQ 35SSBB4035630NRPEL4 – Frequently Asked Questions
1) Should I order the EL4 or the EL8 version of the PDQ 35SSBB-EL electrified hinge?
Pick by how many devices need power or signal through the door. The EL4 carries 4 conductors (two 20 gauge, two 26 gauge) and suits a single electrified function, like an electrified lock or exit device trim. The EL8 carries 8 conductors at 28 gauge, enough to run a lock plus a request-to-exit switch plus a door position switch through the same hinge. If there is any chance of adding monitoring later, the EL8 gives you spare conductors without re-prepping the door and frame.
2) Can the PDQ 35SSBB-EL electrified hinge go on a fire-rated door?
Yes. PDQ states the EL4 and EL8 electrified hinges are UL listed and conform with NFPA 80-2010, Section 6.4.3.1 for fire door hardware, and are certified to ANSI/BHMA A156.1-2013. The ANSI/BHMA function is A5112.
3) Is a stainless steel electrified hinge necessary for an exterior door, or will the steel version do?
For exterior openings and corrosive environments, PDQ specifies the stainless steel hinge, which is what the 35SSBB-EL is. The plain steel EL hinges are intended for interior doors in non-corrosive environments. Coastal, pool, kitchen and wash-down areas are where the stainless pays for itself.
4) What size PDQ 35SSBB-EL hinge do I need for my door?
Four sizes are offered: 4 x 3-1/2 inch, 4 x 4 inch, 4-1/2 x 4 inch and 4-1/2 x 4-1/2 inch. Hinge height is driven by door weight and thickness, and width by door thickness plus any trim clearance you need the door to swing past. On 1-3/4 inch commercial doors the 4-1/2 x 4-1/2 is the usual choice; 4 x 4 is common on 1-3/8 inch interior doors.
5) What does the ISMC option on the PDQ EL hinge actually get me on the install?
The EL4-ISMC and EL8-ISMC add a Molex connector at the hinge, so lock or strike leads plug in instead of each conductor being hard-wired and spliced in the frame. It cuts termination time and makes swapping a lock later a plug-off, plug-on job. If your electrified lock leads are already pigtailed to plug in, order the ISMC version.
6) Is this a full mortise hinge, and does it come with screws?
The 35 series is full mortise, so it mortises into both the door edge and the frame rabbet. Each hinge ships one per carton with 12-24 x 1/2 inch flat head machine screws for metal frames and doors and 12 x 1-1/4 inch flat head wood screws for wood applications, so no separate fastener order is needed.
7) Does the PDQ 35SSBB-EL come with a non-removable pin for an outswinging exterior door?
Yes, NRP is standard on the EL Series, not an extra to specify. That matters on outswing exterior doors where the hinge barrel is on the unsecured side and a removable pin would let someone lift the door out. The NRP designation shows up in the part number, for example 35SSBB4545630NRPEL8.
8) How many electrified hinges do I need per door, and do the other hinges have to match?
Only one electrified hinge is needed per leaf; it is the power transfer point between frame and door. The remaining hinges on the opening are standard non-electrified hinges of the same size and finish. Order the EL hinge in the same size and finish as the rest of the set so the openings look consistent, and mount it in the position your wiring run reaches, typically the top or center hinge location.
9) Is the PDQ 35SSBB-EL heavy duty enough for a high traffic entrance?
It is a standard weight 2 ball bearing hinge tested to over 100,000 cycles, and it is rated commercial. For high traffic openings with electrified locks or exit devices that is its intended use. For heavier or abused doors, PDQ builds the same EL wiring options on a 4 ball bearing heavy weight hinge instead.
10) What finishes does the PDQ 35SSBB-EL electrified hinge come in?
Two: 630 satin stainless steel and 622 flat black. The 630 is offered across all four sizes; 622 flat black is offered in the 4-1/2 x 4-1/2 inch size. If you are standardizing a building on black hardware, the 4-1/2 x 4-1/2 is the black option.
