Base plates are the foundation of any ground-supported truss system. They sit flat on the floor and anchor the bottom of each vertical truss leg, distributing the structural load across a broad, stable footprint instead of concentrating it on a single point. Without the right base plate, a truss column has no stable anchor — the base plate is what turns a vertical section of truss into a standing structure.

Buyers in this category are event producers, exhibit builders, and production managers speccing complete ground-supported systems. If you are building a booth, a stage backdrop, or any freestanding truss structure, you need a base plate for each vertical leg position. The right plate depends on the truss footprint at the base and the vertical load the leg will carry.

Truss Genius carries multiple base plate sizes to match different truss configurations across the EVT290S, EVT290T, and EVT290I series. The flat floor contact surface sits directly on convention hall floors, concrete, or staging without requiring permanent anchoring for temporary installations. A bolt pattern on the top face accepts the vertical leg fitting and locks the assembly securely.

Steel hardware is used throughout the connection points for strength at the critical load transfer zone where the vertical truss meets the plate. For temporary event use, the system requires no floor penetration or adhesive — the weight of the truss and its load keeps the plate in position. For permanent or semi-permanent installs where additional securing is required, the bolt pattern accommodates floor anchors. Select the base plate size that corresponds to your truss chord footprint and system configuration.
