I have been using Cat5 cable from windy city wire and I have never had so many bad crimps in my 10 years in the field. I have not had a problem with this wire and west penn cat5 cable. I guess check with wire manufacturer before buying this product.
Works well, and guides wire into individual slots. You have to know the color code.
MCM has a tremendous selection of products that make my job easier to perform. Along with great pricing and fast shipping, I enjoy ordering and using their products.
