An overhead door frame assembly has a horizontal header connected to tripod legs with splice assemblies. Each tripod leg has two upright columns connected to an upright I-bar. A splice assembly is fastened to each upright column. Hinges pivotally mount the overhead door to the header to allow hydraulic cylinders to move the overhead door to an open position and a closed position.
