For use in instances where the windshield extends over the bottom of the pinchweld. In these cases, it is necessary to use guide pins to guide the wire/cord into the urethane to avoid damaging the pinchweld. Start with the guide pin flush with the edge of the glass then slide each pin into the urethane until secure. Space all 7 pins out evenly along the bottom of the windshield prior to running your wire/cord. This will keep your wire/cord secure and protect the pinchweld during removal.
