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 always delivered an excellent service, ordered parts arrive on time and in excellent condition.
