Works great with all speaker wires
Size: 6 pairs
It works pretty well with standard and thin speaker wires. It makes so much easier to plug and unplug speaker wires. Color coded makes it easier for future. Banana plugs are worth. Double screws ensure wires remain securely attached. Screws are bit too tiny and had to run to the store to get one of those fine tip screw driver though.
