Ceramic Ball and Socket Fish Spine Beads (also called “Fish Spine Beads”), are concave on one end and convex on the other. When ceramic ball and socket fish spine beads are strung convex to concave, the wire can flex, twist or bend and still maintain the ceramic insulation. Applications are, but not limited to: Insulating bare electrical wire in air or vacuum systems and high temperature heating element wire insulation.
Du-Co Ceramic Ball & Socket Fish Spine Beads are available in bulk or in 6″ and 12″ paper sleeves. For sleeved ceramic beads, insert wire through the paper tube of beads and pull string which splits and removes the paper, ceramic beads are applied in seconds.
