Summary:An automatic lock mechanism is provided for locking adjustable frame system components together. A locking mechanism includes a locking pin having a shaft, a head and a biasing spring cooperates with a stud and slot locking mechanism. A stud is inserted into a slot, for example, a teardrop shaped slot, and then moved to the direction of insertion. The locking pin then extends into slot, preventing inadvertent upward movement of the horizontal member.
