Review on ProConnex 42400 π Intersystem by Sigma Electric by Greg Simms
High quality connector
The Sigma 42400 is a high quality connector jumper that is easy to install and is suitable for connecting ground electrodes, telephone and internet cables and more. It's relatively inexpensive and I recommend it to anyone who needs to ground these systems to a convenient location outside or inside the home.
Pros
- Tools and household products
Cons
- Low repairability
