Bass Equipment manufactures it's own J-Clips. They are engineered in size and shape especially for cage construction. These clips are available only through Bass and it's distributors. Don't be misled by lighter weight "cheaper" clips...there IS a difference!
I have been using these since I was a kid so we won't mention how many years that has been! They are just as good today as they were back in the 60's.
perfect for what I will be using them for. Making perch traps
