The Sava Trailer Catchment Device is designed to prevent an uncoupled trailer incident from occurring whilst not interfering with the fifth wheel in any way, the company says. The use of the Trailer Catchment Device can prevent unnecessary damage to trailers caused by an uncoupling event. Drivers have peace of mind and job security knowing that the trailer will not become uncoupled through driver error caused by the driver not coupling correctly to the vehicle or fifth wheel failure.
