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.
The web site was easy to use, I found everything I was looking for. I like the one stop shop. I am telling all my friends about MCM Electronics.
