The beadsfit over solid conductors and are extended long enoughto reach a cooler area where flexible wires can beattached. To order, specify ceramic beads and length,and additional lead length.No-heat sections are recommended in applications whereleads may be exposed to excessive heat, thus requiring acooler lead end. Also use when heat is not required alongthe entire length of the metric FIREROD. No-heatextensions are available on all diameters with both pinstyle and swaged-in leads. To order, specify no-heatsection and length of no-heat.Post Terminals20 mm( 3 /4 in.)30 mm(1 3 /16 in.)Post terminals provide a quick, secure connectionwith ring or fork connectors or bus bars.
