Ensure reliable electrical connections and prevent fraying or breaking your wire strands when terminating conductors in screw clamp terminal blocks. Their shorter lengths and uninsulated bodies offer advantages when making terminations in narrow widths. Uninsulated ferrules prevent wire strands from fraying or breaking and are extremely cost effective. To ensure efficient ferrule crimping, always select the smallest ferrule diameter that fits the wire and use only professional crimping tools.
