Add-a-bead clasps (aka tube-lock clasps) are designed for use with chain, wire and cord. The slim profile of the tube clasp allows large hole beads or large loop bails to slide right over the clasp onto the necklace, while a simple push-and-twist design allows for easy on and off. Apply durable glue, such as Loctite® 409 Gel, to the inside of the tube, slide onto your wire or thin cord and allow to dry. Works best with lightweight designs.
