Stainless steel rod clip to secure wire to 3/8 In. fence posts. Stays with the post when relocating the fence- unlike t-posts which use a clip that is often lost while moving the fence. Securely attaches to fiberglass post but allows conductor to move freely. Squeeze loops together to slide clips on, off, up, or down. Manufacturer recommends using pliers to position clips as they can be challenging using fingers only. Fits all 3/8 In. rods.
