A safety block device for supporting a generally vertically movable component about a guide post of a press device. According to one embodiment of the invention, the safety block device includes a generally upright column ( 42 ) adapted to be disposed adjacent the guide post ( 18 ) and moveable between a retracted non-working position, wherein the column does not support the moveable component, and an extended working position, wherein the column is effective to support the moveable component and prevent movement thereof. The column includes an upper end portion and a lower end portion. According to one feature of the invention, the lower end portion of the column includes a generally rounded first portion ( 62 a) and a generally second flat portion ( 62 b) which is slightly offset with respect to the first portion. As a result of this, when the safety block device is in the extended working position, the generally flat second portion of the lower end portion of the column rests firmly on an underlying surface of either the safety block device or the press device.
