Cable Crossover with lid load bearing capacity per typical tyre imprint (20 x 20 cm): 5 tons. Crossover lengths are joined by individually available connector plugs. Each crossover is supplied with one pair of connector plugs. The lid closes down onto a patented "interlock zipper" (EU Patent No.: EP1366550) which is moulded into the base and lid - no Velcro to tear off or clog with dirt. A complete range of accessories expands the Defender III into a flexible system to protect your cables and multicores.
