Abstract: A connector system for attaching one or more flexible fencing webs or rails to fence posts is provided. For each post, at least one elongated, flexible strand, preferably a plastic coated wire, is attached to the post in overlying relationship to the web or rail. The free ends of the strand are firmly fixed to the post by at least a pair of fasteners firmly driven into the post, straddling the strand. Additional fasteners are driven into the post, straddling the strand, at least adjacent upper and lower edges of the web or rail. These fasteners may be driven into the post to a lesser extent, so that the web or rail is constrained against substantially vertical movement, but free to move axially in the direction of its elongation. In one embodiment, the flexible strand comprises a single, plastic coated wire. In another embodiment, the strand comprises a pair of high tensile strength wires ensheathed in a single plastic strip.
