Zephyr Tool ZHP100 Zephyr Collar Removal Pliers feature a diamond shaped jaw which allows the pliers to grip from any direction and may be used to remove collars in open access applications. The Zephyr Tool ZHP100 Zephyr Collar Removal Pliers are best suited to smaller aluminum collars (-5, -6, -8). Zephyr offers 2 styles, both are best suited to small collars. It has been our experience that they do not work as well with large collars, or steel/titanium collars where greater gripping force is required to achieve the required break away torque.
