The TB Plus fence provides the same shock absorbing properties as the TB 400 flexible barrier with the added protection of a built-in fence. The TB 400 tube provides excellent resistance where there is a risk of impact from vehicles such as forklifts. The built-in fencing offers further protection by guarding machinery from falling goods or nearby pedestrians.  The fencing is made from flexible materials to minimise damage caused by impacts.
