Unsecured cargo lying around an enclosed van or trailer is likely to get ruined from rocky roads, sudden stops, and contact with other cargo. E-Track cargo bars are designed to restrain freight during transit with little effort. Once an E-Track rail system is installed in your trailer, these shoring beams can be mounted in moments, making E-Track shoring beams fantastically easy to use. E-Track shoring beams have a spring fitting at each end. Simply insert the fittings into slots on opposite E tracks. To remove, press the lever on each fitting and slide out. The levers are easy to press with just a slight pressure and can be done easily even when wearing utility gloves. In addition to their basic function of restraining cargo, E-Track shoring beams can also be used to create multiple decking levels for cargo positioning. Place several cargo bars at the same vertical level, set a board of plywood atop the beams, and use as a mock shelf. These tough aluminum E-Track cargo bar shoring beams are adjustable in length from 85" to 96". They have an assembly break strength of 6,000 lb. and a working load limit of 2,000 lb.
