"Shoring beams offer a great way to quickly secure cargo using high-strength aluminum and adjustable E-fitting ends that lock into E-track. Designed for commercial use, these shoring beams are adjustable from 92"" to 103"". Using high-strength aluminum with a 2,200 lb. break strength, they can also double as decking beams to create vertical-storing shelves. The release mechanism is easy to operate, even when wearing heavy gloves. The beams will also work with A-tracks."
