Each set pairs a 7.1mm outside diameter Guardian II Comfort Trigger ear nut with a matching 2-notched ear post, sold together as a single set. Positive locking backs have been trusted since the French introduced the ZOP system in the late 20th century—the Guardian II refines that legacy with larger, easier-to-use comfort triggers that snap firmly around a groove on the matching post, requiring simultaneous compression of both tabs to release. Made in the USA from 100% recycled precious metal by a leading findings manufacturer certified to ISO 14001:2015 (Environmental) and ISO 9001:2015 (Quality Management System) standards.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eGuardian II Comfort Trigger design with two large, easy-to-use release tabs\u003c\/li\u003e\n\u003cli\u003ePositive locking mechanism—both tabs must be compressed simultaneously to release\u003c\/li\u003e\n\u003cli\u003eTabs snap securely around a groove on the matching 2-notched ear post\u003c\/li\u003e\n\u003cli\u003eMatching post and nut sold as a set for guaranteed compatibility\u003c\/li\u003e\n\u003cli\u003eMade in the USA from 100% recycled gold or platinum\u003c\/li\u003e\n\u003cli\u003eManufacturer holds ISO 14001:2015 and ISO 9001:2015 certifications\u003c\/li\u003e\n\u003cli\u003eAvailable in 14K yellow, 14K white, 18K yellow, 18K white, and platinum\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eStyle\u003c\/th\u003e\n\u003ctd\u003eGuardian II with Comfort Triggers\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOutside Diameter\u003c\/th\u003e\n\u003ctd\u003e8.3mm \/ 0.326\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePost Diameter\u003c\/th\u003e\n\u003ctd\u003e1.07mm \/ 0.046\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePost Length\u003c\/th\u003e\n\u003ctd\u003e11.0mm \/ 0.433\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eNotches\u003c\/th\u003e\n\u003ctd\u003e2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSold As\u003c\/th\u003e\n\u003ctd\u003ePer piece (1 post + 1 nut per piece ordered)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCountry of Origin\u003c\/th\u003e\n\u003ctd\u003eUSA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003e100% recycled precious metal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eAvailable Options\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003ePart #\u003c\/th\u003e\n\u003cth\u003eMetal Type\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e200-304\u003c\/td\u003e\n\u003ctd\u003e14K Yellow Gold\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e201-304\u003c\/td\u003e\n\u003ctd\u003e14K White Gold\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e20B-304\u003c\/td\u003e\n\u003ctd\u003ePlatinum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e20C-304\u003c\/td\u003e\n\u003ctd\u003e18K Yellow Gold\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e20E-304\u003c\/td\u003e\n\u003ctd\u003e18K White Gold\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1 Guardian II Comfort Trigger ear nut\u003c\/li\u003e\n\u003cli\u003e1 matching 2-notched ear post\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eEach piece ordered includes one complete set.
