Based on our own experience, this product was a great option for our industrial electrical needs. The Sigma Electric ProConnex 49002 Reducing was easy to use and provided a secure connection .The design was sturdy AND durable which is important for our heavy-duty usage. The only drawback we encountered was the price point, which may be a consideration for those on a tight budget. Overall, we highly recommend this reducing option for any industrial and scientific wiring and connecting needs..
