The Countryman Earclip Cable Hook attaches to the back of the Earclip to position and secure the E6 Snap-On cable. The Earclip cable hook is designed to grip the Earclip and cable very firmly to prevent accidental movement or removal. Although the hook grips very firmly, it will slide easily along the Earclip tubing, allowing for precise placement. The Earclip Cable Hook is sized to fit 1mm diameter E6 cable.
