Locknetics DC-AL-20 – Frequently Asked Questions

1) What is a door cord for, and do I need one to run power to an electrified lock?
A door cord is the protective conduit that carries wiring from the frame across the hinge gap into the door leaf, which is exactly what an electrified lock or strike needs when the power source lives in the frame. The Locknetics DC-20 is a 20 inch medium duty cord with a stainless steel cable jacket and aluminum end caps. Without something in that gap, the wire flexes bare every time the door swings and eventually breaks.
2) Is the Locknetics DC-20 door cord surface mounted or does it get mortised into the door edge?
Surface mount. The DC-20 fastens to the face of the frame and the door with the mounting hardware included in the box, so there is no routing or mortising of the door edge. That makes it the practical choice on a retrofit where you are adding an electrified device to an existing opening and do not want to pull the door to machine it.
3) What length door cords does the Locknetics DC Series come in, and how do I pick between 12, 16, and 20 inch?
The DC Series door loops come in 12, 16, and 20 inch. The DC-20 is the 20 inch. Length has to cover the arc the door travels plus slack at both anchor points, so wider openings and doors with a lot of swing take the longer cord; a short cord that goes taut at full open is what tears the cable out of the end cap.
4) Should I use a surface door cord or a concealed power transfer for my electrified opening?
Different jobs. The Locknetics DC-20 is a surface mounted cord: it goes on without machining the door or frame, which is why it wins on retrofits and on doors you cannot take down. A concealed transfer such as the ABH PT200 Series hides the wiring entirely but has to be mortised into the door and frame edge, so it is a new construction or shop prep decision. If the opening is already hung and the electrician needs power across it this week, the cord is the answer.
5) What is the difference between a Locknetics DC-20 door cord and an ABH PT200 concealed power transfer?
They solve the same wiring problem two different ways. The Locknetics DC-20 is a surface mount door cord that runs a protective conduit for wires from the frame to the door, with a stainless steel cable and aluminum end caps, and mounting hardware is included. The ABH PT200 Series is a concealed power transfer carrying 18 AWG wiring, so the wire path is hidden inside the door and frame rather than looped across the gap. Choose the DC-20 when the door and frame are already hung and you need to add power to an electrified lock without mortising either one; choose the PT200 when the opening is being prepped and a concealed run is required.
6) Is an ABH power transfer a drop-in replacement for a Locknetics DC-20 door cord?
No, and the difference shows up at install rather than at the wire. The DC-20 is a surface mount cord with aluminum end caps that fasten to the face of the door and frame using the included mounting hardware. The ABH PT200 Series is a concealed power transfer with 18 AWG wiring and the ABH PT1000 Series is a power transfer rated 24VDC at 1A; swapping either one in for an existing DC-20 means preparing the opening for a transfer device and abandoning the surface fastener holes. For a like-for-like replacement of a failed cord, stay with a DC Series loop in the matching length.
7) Does the Locknetics door cord come with mounting hardware or do I need to order screws separately?
Mounting hardware ships with the cord. You supply the low voltage wire pulled through it and whatever the electrified device at each end requires; the cord itself is ready to hang.
8) What size hole do I need to drill for a Locknetics DC Series door loop?
The loop measures 5/16 inch inside diameter and 7/16 inch outside diameter. Since it is a surface mounted cord, that 7/16 inch outside dimension is what has to clear at the end caps rather than a bore through the door, and the 5/16 inch inside diameter is the working space you have for the conductors you are pulling.
9) Does the Locknetics DC-20 door cord come with wire in it, or do I pull my own conductors?
The DC-20 is the conduit and the hardware, not a wiring harness with a stated conductor count. If you need a transfer that arrives with conductors specified, the ABH PT200 Series is listed with 18 AWG wiring and the ABH PT1000 Series carries a 24VDC 1A rating. Match whichever you pick to the current draw of the lock or strike you are feeding.
10) Can I use one door cord to feed an electrified lock on a pair of doors?
No. Each leaf that carries an electrified device needs its own transfer, because the cord bridges one frame to one door across that leaf's hinge gap. On a pair with electrified hardware in both leaves, order two DC-20 cords.
11) Does a Locknetics door cord carry a voltage and current rating like the ABH PT1000?
The two are described on different terms. The ABH PT1000 Series power transfer is rated 24VDC at 1A, which is the figure to check when the device on the door has a defined current draw. The Locknetics DC-20 is described by its physical build instead: a 20 inch medium duty cord with stainless steel cable that resists abrasion and damage, aluminum end caps, and a 5/16 inch inside loop diameter with a 7/16 inch outside loop diameter, which is what governs how many conductors the loop will accept. If the job specification is written around an electrical rating, size to the PT1000; if it is written around conductor count and door swing clearance, the DC-20 loop dimensions are the controlling numbers.
12) Can I substitute a shorter door loop for the 20 inch Locknetics DC cord?
Within the Locknetics DC Series the door loops come in 12 inch, 16 inch, and 20 inch, so a shorter loop is a same-family substitution when the frame to door hinge gap and the swing allow it. The length has to cover the full arc the door travels without the cord binding at full open, which is why the longer 20 inch cord is used on wider openings. Substituting an ABH PT1000 Series or PT200 Series power transfer is not a length swap at all - those are power transfers rather than surface loops, and the PT200 in particular is concealed, so the door and frame preparation is different.
13) Which option keeps the wiring out of sight on a glass front or high visibility entrance?
A concealed transfer does. The ABH PT200 Series is a concealed power transfer running 18 AWG wiring, so nothing crosses the hinge gap where it can be seen or grabbed. The Locknetics DC-20 is a surface mount cord and stays visible along the hinge side, which is why it is finished to match the opening - it comes in 628 satin aluminum and 613 dark bronze. On back of house, stairwell, and service openings the visible loop is routine; on a front entrance the finish match or a concealed transfer is the usual call.
14) What finishes does the Locknetics DC-20 door cord come in?
Two: 628 satin aluminum and 613 dark bronze. On an exposed surface mount part sitting on the hinge side of the frame, that choice is about matching the hinges and frame paint already on the opening, since the cord is visible whenever the door is open.
15) Is the Locknetics DC-20 door cord rated for commercial use, and how well does the cable hold up?
It is a commercial door hardware item, built medium duty with a stainless steel cable that resists abrasion and damage. The cable is the wear part on any door loop, since it flexes on every cycle, and stainless is there for that reason. For an opening with heavy traffic, the higher duty and shorter runs in the series are worth a look.
