A double action securing device for the drop side of a crib comprises a guide member connected to the crib or to the drop side in a vertically oriented position. A slide member is slidably mounted to the guide member between two positions for raising and lowering the drop side. A catch pin is axially and rotatably mounted to the slide member and engageable with an opening of the guide member in at least one of the relative positions. The catch pin has a head which defines a recess for embracing a lower edge of the guide member opening. The weight of the slide member causes the head recess to drop over the lower edge of the opening to lock the slide member with respect to the guide member. The catch pin can further be rotated to increase the engagement. A disengagement or unlocking of the slide member from the guide member thus requires at least two distinct movements, one for raising the catch pin and thus disengaging the head recess from the opening edge, and the other for axially withdrawing the catch pin head from the opening. When the catch pin is rotatable, a third motion is required to initially align the head with the opening, and thereafter lift and axially withdraw the head.
