The Guardian II Positive Locking Post & Back Sets are the professional standard for secure fine jewelry earring findings. 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.
