For heavy duty deer fencing installations, this in-line monofilament guide clamp is an improvement and alternative to self-locking ties when attaching monofilament wire to in-line posts. The guide consists of a black-coated steel brace band, eye bolt, and two nuts. These steel pieces are weather-resistant, and a permanent solution for attaching your monofilament. The guide clamp creates a channel allowing the monofilament to move back forth and give when impacted by falling limbs and other dangers to your fencing. These guide clamps are attached to the top and bottom of the post. If you are running an optional middle line of monofilament, you can use these in the middle as well.
