FUNNY NAME - SERIOUS RESULTS Here at Lock Jawz, we are the guys thinking differently about the livestock fencing industry! It all started a few summers ago building fences on our property. The products available from the local retailer were limited to say the least. "They were either to tight or too loose, and the ones that did fit, broke easily or were missing pins." After an entire summer of frustration, we decided to redesign the insulator from the ground up, and the T-360 is the result. It was specifically designed for use with ALL 1.25/1.33 lb standard t-posts. With its 360° mounting options and ability to make tight 180° turns, your imagination is the only limit when designing your fields.
