Having trouble keeping your wire securely attached to your posts? Our Zareba Black Pin-Lock Wood and T-Post Insulator tightly fastens electrified wire to wood, metal and T-posts (1.25 or 1.33 T-posts) without losing energy through the post. A molded pin holds wire tightly, and when you are ready to release the wire, simply pull the pin.
