A cane bolt is spring biased up to allow a movable barrier with which the cane bolt is engaged to move. The cane bolt can be pushed down into a strike hole to prevent movement of the barrier. To hold the cane bolt down, a pin on the cane bolt abuts a slotted stop on the barrier. To raise the cane bolt, the cane bolt is simply rotated so that the pin aligns with and thus passes through the slot, allowing the spring to urge the cane bolt up.
