The Brown Industries Lock-n-Load Modular Wall System allow for users to convert a curtainside into a dry freight truck, and back again, in minutes, says the company. Equipped on both the road and curb sides with logistic posts, Lock-n-Load Modular Wall Systems move easily into place, while steel stake pockets ensure that the modular walls form a secure, rigid wall when locked into place. Operators can easily retract panels to facilitate easier loading, and rigid slip-resistant aluminum ramps ensure simplified loading and unloading, as well as increased employee safety.
