The facts
- Maker: Zonit.
- Locks at: both ends.
- Needs on the PDU side: any plain outlet.
- Needs on the equipment side: any standard inlet (C13 / C15 / C19 connector).
- How it holds: Zonit's original two-ended lock. The cords we stock carry Well Shin's locking plug (WS-003) and auto-locking connector (WS-003A): a red slider at each end, the plug gripping inside any standard outlet, the connector gripping any standard inlet. Zonit's later zC14 / zC20 plug used a knurled locking nut instead of the slider: back it out, seat the plug, tighten a quarter to half turn. Remaining stock only.
- How to release: Pull the red slider back at the end you are freeing and pull. On a nut-type plug, loosen the nut as far as it goes.
- Published retention: no figure published by the maker.
- Plugs: C14, C20. Connectors: C13, C15, C19.
What it is
Zonit's Z-Lock puts a latch on both the plug and the connector, and neither needs anything special on the other side: the plug grips a standard C13 or C19 outlet, the connector grips a standard C14 or C20 inlet. That makes it the answer to the question the other both-ends mechanisms cannot take, a rack whose PDUs have plain outlets and whose equipment must still not come unplugged.
What we stock
The Z-Lock cords on this site carry Well Shin's locking plug (WS-003) and auto-locking connector (WS-003A): a red slider at each end, the plug gripping inside the outlet, the connector gripping the inlet pins. Zonit's later zC14 / zC20 plug used a knurled locking nut instead of the slider; Zonit's own guide has it backed out, seated, then tightened a quarter to half turn. If a nut-type cord reaches you, that is the one to follow.
End of life
The original Z-Lock is end of life. The cords listed on this site are the remaining stock, sold while they last. Its successor, Z-Lock+, locks into the same standard outlets and inlets and is the version to specify for anything new: Z-Lock+ power cords. Mixing the two in a rack is fine; they lock onto the same hardware.
Release
Pull the red slider back at the end you are freeing and pull the cord. On a nut-type plug, loosen the nut as far as it goes and the plug comes free.
