Spring rings are the most popular type of clasp used for chains worn around the neck: secure, reliable, and easy to use. These \u003cstrong\u003e14K yellow gold open top spring ring clasps\u003c\/strong\u003e are round hollow tubes with a tiny coil spring inside and an attached jump ring for connecting to one end of a chain. A movable, spring-tensioned bolt carries a lever; push the bolt back with your fingernail to open the clasp, and the internal spring inside the tubing holds the bolt firmly closed. Opening and closing a spring ring requires two hands.\u003c\/p\u003e\u003cp\u003eThese clasps carry an \u003cstrong\u003eopen top jump ring\u003c\/strong\u003e for easy attachment to one end of a chain. The jump ring can be twisted closed, but that method is not secure. \u003cstrong\u003eDo not use torch heat to solder the jump ring closed, because the internal spring will be damaged by heat.\u003c\/strong\u003e The correct method is to close the jump ring with a laser welder or a tack welder.\u003c\/p\u003e\u003cp\u003eSold individually, by the piece, in six sizes from 4.5 mm to 8.0 mm.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eClassic spring ring construction: a hollow round tube with an internal coil spring\u003c\/li\u003e\n\u003cli\u003eOpen top jump ring for easy chain attachment\u003c\/li\u003e\n\u003cli\u003eSpring-tensioned bolt with a lever for one-finger operation\u003c\/li\u003e\n\u003cli\u003eJump ring must be closed by laser weld or tack weld, \u003cem\u003enot\u003c\/em\u003e torch soldering\u003c\/li\u003e\n\u003cli\u003eSix sizes from 4.5 mm to 8.0 mm\u003c\/li\u003e\n\u003cli\u003eSold by the piece\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eAvailable Options\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003ePart #\u003c\/th\u003e\n\u003cth\u003eSize\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e360-400\u003c\/td\u003e\n\u003ctd\u003e4.5mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e360-401\u003c\/td\u003e\n\u003ctd\u003e5.0mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e360-402\u003c\/td\u003e\n\u003ctd\u003e5.5mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e360-403\u003c\/td\u003e\n\u003ctd\u003e6.0mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e360-404\u003c\/td\u003e\n\u003ctd\u003e7.0mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e360-405\u003c\/td\u003e\n\u003ctd\u003e8.0mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eNotes\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eTorch heat damages the internal spring; close the attached jump ring with a laser welder or tack welder.\u003c\/li\u003e\n\u003cli\u003eOpening and closing a spring ring clasp requires two hands.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Otto Frei","offers":[{"title":"14K Yellow \/ 4.5mm","offer_id":47551487672534,"sku":"360-400","price":13.8,"currency_code":"USD","in_stock":true},{"title":"14K Yellow \/ 5.0mm","offer_id":47807374590166,"sku":"360-401","price":15.44,"currency_code":"USD","in_stock":true},{"title":"14K Yellow \/ 5.5mm","offer_id":47807374655702,"sku":"360-402","price":17.24,"currency_code":"USD","in_stock":true},{"title":"14K Yellow \/ 6.0mm","offer_id":47807374622934,"sku":"360-403","price":23.31,"currency_code":"USD","in_stock":true},{"title":"14K Yellow \/ 7.0mm","offer_id":47807374524630,"sku":"360-404","price":68.36,"currency_code":"USD","in_stock":true},{"title":"14K Yellow \/ 8.0mm","offer_id":47807374557398,"sku":"360-405","price":59.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9832\/0342\/files\/14k-yellow-open-top-spring-rings-4mm-to-8mm-otto-frei-1.jpg?v=1719955060","url":"https:\/\/www.ottofrei.com\/ja\/products\/spring-ring-clasp-open-top-14k-yellow-4-5-8mm","provider":"Otto Frei","version":"1.0","type":"link"}
