This Sterling Silver lobster clasp measures approximately 21.00mm in width, 48mm in length, and features a flat loop at one end, ready to attach to a chain or jump ring. Lobster trigger clasps are highly popular jewellery findings that are regularly used in jewellery making to fasten chains, necklets, pendants and bracelets. The claw shaped clasp is opened and closed with the aid of a sprung 'trigger' component. These simple but sturdy jewellery clasps are ideal for a subtle look which does not detract from your pendant or necklace designs.
