The tops of T-posts and U-posts have sharp corners and if a pounder has been used to set them, they also may have more dangerous edges. The solution is Tech Team’s #902 T-post safety cap. The cap fits snuggly to the top of the post, is made from vinyl plastic, and has a clip that insulates and supports both hot wire and ribbon.
