A multi-adjustable, rotating, and opposite-double-locking umbrella-stanchion system is operated with one finger for oppositely double-locking and -unlocking the umbrella-supporting post of a crank-arm-operated umbrella to secure it in different positions. The system comprises a canopy system, a supporting post, a stanchion base, a U-shaped rotational lever, an actuator arm, a push rod, two opposite L-shaped locking arms, two opposite locking cleats, radial teeth, and two opposite tension springs for pushing the opposite locking cleats downward to oppositely double-lock the post and the canopy system, in place. The radial teeth are molded to the stanchion base. To operate the system, lift the U-shaped rotational lever with one finger to lift the opposite locking cleats to oppositely double-unlock them. Next, rotate the supporting post to a desired position. Then, release the U-shaped rotational lever to oppositely double-lock the opposite locking cleats between the radial teeth.
