Wire Vise & One-Way Anchor Vise (Pack of 10)
The one way anchor vise (also known as wire vise, anchor vice) is used to anchor a wire in a through-post installation process. this installation technique saves time and money and is very easily performed as very little additional hardware is needed.
Installation is performed by simply running your wire through a pre-drilled hole and through the anchor vise. The wire vise grips the line and prevents it returning back through the hole. As you pull the line through it comes to reach your desired tension.

Post installation Notes:
You may want to consider the use of some insulated tubing to protect the contact points between the wire and your wood posts.
Some wood post treatments can interact with steel. Please do some research into ACAs (ammoniacal copper arsenate) wood treatment for more info. this applies to both the vise itself as well as other steel materials in use such as your wire, electric fencing leads, etc.
