This is a Cardas Clear Beyond XL made by Cardas with their older Clear Beyond connectors (as is very obvious in the photos).
It is very short and suitable for connecting a power block to the wall, unless you happen to have have a component right up against a power outlet or or other power distirbutor.
It is only 23 inches long from connector tip to connector tip.
The cable is incredibly thick, the connectors are long and there is very little room to run it, so make sure you can accomodate this reference grade power cord in your system.
I used it to a power block then to two monoblocks using Clear Beyond cables with right angle iecs (also for sale, see my other listing).
