Proto J365 0° Large External Retaining Ring PliersFEATURES: Spring loaded ratchet mechanism minimizes operator fatigue by allowing the ring to be compressed or expanded through gradual "moves" and then locks at the desired size without continued pressure on the handles. Heavy and large rings are safely and easily controlled. Replaceable tips in 0, 45 and 90 make it possible to remove and install rings in most applications. (Replacements available).
