An apparatus is provided for improved retention of magnetically attractable die rules inserted into slots of a retaining board. In a die rule retaining board, a plurality of chambers are oriented substantially perpendicular to a die slot and the direction of insertion of a die rule into the retaining board. In one embodiment, each of the chambers has an open face to permit communication between the chamber and a die slot in the retaining board. A magnetic die rule retention device is located within each chamber and includes a contact face intended to contact and retain a magnetically attractable die rule inserted into a respective die slot. Once the die rule is completely inserted into the die rule slot, the contact face of the magnetic retention device exerts an attractive force against the die rule in the direction of the retention device slot and securely holds the die rule within the die slot.
