SDC PTH-4Q – Frequently Asked Questions

1) How do I run power to an electric lock or exit device on the door without exposed wire?
An SDC PTH Series power transfer hinge carries the conductors through the hinge itself, from the frame leaf into the door leaf, so nothing crosses the gap where it can be cut or pulled. It replaces one of the door's existing hinges and comes with a 5 foot cable for the runs back to the power supply or access control panel. That is the concealed, vandal-resistant alternative to a surface armored door cord.
2) What is the difference between the SDC PTH-4, PTH-10, and PTH-2+4 hinges?
Conductor count is the whole difference. The PTH-4 carries four conductors, the PTH-10 carries ten, and the PTH-2+4 carries six (a 2 plus a 4 grouping). Count what has to cross the door before you pick: a single electric strike or electrified exit device trim may only need two or four, while an electrified mortise lock with request-to-exit and latch monitoring plus a card reader on the door can eat ten in a hurry. All three are the same 4-1/2 x 4-1/2 inch standard weight 5-knuckle hinge.
3) Will an SDC PTH hinge fit my existing door and frame hinge prep?
The PTH hinges are 4-1/2 x 4-1/2 inches, which is the standard commercial full mortise hinge size, so on an opening already prepped for 4-1/2 inch hinges it drops into an existing leaf pocket. The one thing that changes is the frame: you need a wire path out the back of the frame leaf to get the cable to the power supply, so plan on a hole through the hinge pocket even though the mortise itself is unchanged.
4) What does the Door Position Switch option on the SDC PTH hinge do, and should I order it?
Every PTH model (PTH-4, PTH-10, PTH-2+4) can be ordered with or without a built in door position switch. With DPS, the hinge itself reports whether the door is open or closed, so your access control panel gets door status without a separate magnetic contact drilled into the head of the frame. Order it if you need door-forced or door-held-open alarms and want one less device in the opening. Skip it if the opening already has a contact or you only need power across the door. This is a factory build, not a field add.
5) Is an SDC PTH hinge rated for a high traffic entrance, or is it only for light use?
The PTH Series is tested to 800,000 endurance cycles and is built as a commercial hinge, which puts it in range for main entrances, corridors, and stairwells that cycle hard all day. It is a standard weight hinge, though, not heavy weight. On a very heavy or oversized door, or one with an aggressive closer, spec a heavy weight electrified hinge instead: the BEST CECB168-18 is a heavy duty full mortise concealed bearing electrified hinge with 8 wire.
6) What is the closest equivalent to an SDC PTH-10 ten conductor power transfer hinge?
The SDC PTH-10 carries ten conductors in a 4-1/2 inch by 4-1/2 inch five knuckle hinge. The nearest peers run eight wires in the same 4-1/2 inch by 4-1/2 inch footprint: the Detex EWH8 five knuckle electric hinge is an 8 wire hinge in satin chrome, and the BEST CECB168-18 is a steel full mortise concealed bearing heavy weight electrified hinge with 8 wire. If the door only needs eight circuits - lock power, monitoring, request-to-exit - either drops into the same hinge prep. If you need all ten conductors, the PTH-10 is the one to hold, because the 8 wire units cannot be made to carry more.
7) What is a simpler substitute for the SDC PTH-4 four conductor hinge on a single electric strike?
An opening with one electric strike and no monitoring usually needs two to four conductors, and the SDC PTH-4 four conductor hinge covers that. So does the Design Hardware ETW2-BB5, a 4-1/2 inch by 4-1/2 inch electrified standard weight ball bearing hinge in the BB5 series - same hinge size, so the frame and door prep are unchanged. The Design Hardware unit is rated medium duty, while the SDC PTH series is standard weight rated to 800,000 endurance cycles, which is the deciding factor on a door that cycles all day versus a back-of-house door that does not.
8) Which electrified hinge should be used instead of the SDC PTH series on a heavy weight door?
The SDC PTH series is a standard weight 4-1/2 inch by 4-1/2 inch five knuckle hinge. On a heavy or high-abuse leaf where the specification calls for a heavy weight hinge, the BEST CECB168-18 is the one to quote: a steel full mortise concealed bearing electrified hinge, rated heavy duty, carrying 8 wire. The Securitron EH Double Duty electric hinge is the other direction to look. Confirm the weight class on the door schedule before substituting, because a standard weight hinge and a heavy weight hinge are not interchangeable on the same opening.
9) Is the RCI 952 the same thing as an SDC PTH-2+4 six conductor hinge?
They land on the same conductor count from different constructions. The RCI 952 is an electrified hinge with 6-conductor wiring and ball bearing construction, rated medium duty. The SDC PTH-2+4 is a six conductor hinge, but it splits those six as two plus four - a separate pair alongside a four wire group, which is how an installer keeps a higher-current lock circuit off the low-voltage signal wires. If the drawing calls for segregated circuits, six generic conductors is not a drop-in for a 2+4. If all six run to the same device, either construction serves.
10) Which electrified hinges match a 4-1/2 x 4-1/2 hinge prep already cut in the frame?
On an existing 4-1/2 inch by 4-1/2 inch prep, the SDC PTH series drops in at that exact size, as does the Design Hardware ETW2-BB5 at 4.5 inch by 4.5 inch and the Detex EWH8 at 4.5 inch by 4.5 inch. That means retrofitting an existing door to electric locking does not require rerouting the frame - the powered hinge replaces one of the existing hinges in the same mortise. Confirm hand and leaf thickness against what is in the opening, then choose on conductor count: four, six or ten with the SDC PTH, or eight with the Detex EWH8.
11) Is one power transfer hinge enough, or do I need to replace all the hinges on the door?
One PTH hinge per door does the electrical work. The remaining hinges stay as they are, and since the PTH is a standard weight 4-1/2 x 4-1/2 inch 5-knuckle hinge, it matches a typical commercial hinge set visually and dimensionally. Middle position is the usual spot so the cable loop sits away from the closer and the top of the door.
12) What else could I use instead of an SDC PTH hinge for an electrified opening?
Same size, different builds are available. The Detex EWH8 is a five knuckle electric hinge in the same 4.5 x 4.5 inch size with 8 wire and a satin chrome finish. The Design Hardware ETW2-BB5 is a 4.5 x 4.5 inch electrified standard weight ball bearing hinge, medium duty. The RCI 952 runs 6 conductors on ball bearing construction, medium duty, which is the closest match to the six conductor PTH-2+4. Match the conductor count to what is on your door first, then the duty level to the door weight and traffic.
13) I need more than ten conductors across the door. Will the PTH-10 work?
No. Ten conductors is the ceiling on the PTH Series, since the PTH-10 is the largest of the three (PTH-4, PTH-2+4 at six, PTH-10 at ten). If your door hardware needs more, split the load across two transfer points or move to a concealed door loop or an electric power transfer sized for the run. Adding a second PTH hinge in the same door is the simplest way to double the available conductors.
14) Does the SDC PTH hinge come with the cable, or do I have to buy wire separately?
The cable comes with it. Each PTH hinge ships with a 5 foot cable, which gives you slack to reach a junction box or the power supply above the frame without splicing at the hinge. What is not included is the low voltage power supply, the access control hardware, and any conduit or raceway your local code requires for the run back from the frame.
15) Do any of the comparable electrified hinges include a door position switch like the SDC PTH does?
The SDC PTH series is ordered with or without an integral door position switch on all three models - PTH-4, PTH-10 and PTH-2+4 - so the DPS contact and the power transfer come through one hinge and one prep. The peer electrified hinges are specified by conductor count and bearing type: the Detex EWH8 as an 8 wire five knuckle hinge, the RCI 952 with 6-conductor wiring and ball bearing construction, the Design Hardware ETW2-BB5 as an electrified standard weight ball bearing hinge. If the access control panel needs a door status input, order the PTH with DPS rather than adding a separate surface or recessed contact to the frame.
16) What is the difference between a five knuckle electrified hinge and a concealed bearing electrified hinge?
The SDC PTH series uses a five knuckle standard weight construction with the wire run concealed through the barrel, rated to 800,000 endurance cycles. The BEST CECB168-18 is a full mortise concealed bearing hinge, where the bearings sit hidden inside the knuckle rather than showing as visible bearing races. The Detex EWH8 is also a five knuckle hinge, and the RCI 952 and Design Hardware ETW2-BB5 are ball bearing constructions. All mortise into the door edge and frame rabbet; the choice comes down to the leaf weight, the traffic and what the rest of the hinges on the opening already are, since mixing constructions on one leaf is what causes uneven wear.
17) Can a Securitron EH be used in place of an SDC PTH hinge for a door with an electric exit device?
Both are electric hinges that carry power from frame to door in place of a surface loop. The Securitron EH is the Double Duty electric hinge; the SDC PTH is a 4-1/2 inch by 4-1/2 inch standard weight five knuckle hinge offered in four, six and ten conductor versions. Match on two things before swapping: the number of conductors the exit device and its monitoring need, and the hinge size the frame is prepped for. An electrified exit device with latch monitoring and dogging feedback often exceeds four wires, which is where the PTH-10 or PTH-2+4 comes in.
18) Can I standardize the SDC PTH hinge across a whole building's access control doors?
It works well as a facility standard. One hinge size covers every opening (4-1/2 x 4-1/2 inches), and the three conductor options let you use the same part family whether a door has a simple electric strike or a full electrified mortise lock with monitoring. Order the DPS version where you want door status reported and the non-DPS version where you do not, and the hinge prep stays identical either way. The 800,000 cycle rating covers the range from a low-traffic mechanical room to a main corridor.
