These spades are used on Unity Audio speaker cables by request.
Made of copper alloy, and gold plated. Will fit cables up to 9 awg.
Crimp required, soldering is recommended.
Stepped 1/4" and 5'16" spacing to fit most binding posts.
Note - spade lugs are NOT recommended unless the posts on your gear can grab a spade and hold it tightly for a long period of time. If you have ANY doubts about this, please use these bananas instead that fit snugly, and never loosen over time:
