Abstract: A telescoping cargo brace is disclosed in which the brace secures cargo on at least three sides while minimizing the use of walls or contact points to secure the cargo. The brace is a fork-shaped or u-shaped telescoping device that secures between adjacent walls of a storage container or transport vehicle. The forked shaped portion of the device has two parallel, spaced apart legs each of which telescopes perpendicularly from a shared cross-member. Likewise, each leg is telescoping. Thus, both the legs and the cross-member are scalable along their respective lengths to adjust to the size of a load of cargo. The brace also includes a third telescoping leg, opposite the fork-shaped portion, so as to permit the device to be installed between adjacent walls utilizing only three contact points. An adjustment mechanism controls extension of the telescoping legs and the outward pressure exerted on the walls by the brace.
