The invention relates to a training door with a door leaf, a frame 1 and locking cylinders 3a-e arranged to lock the door leaf against the door frame. The locking cylinders 3a-e are provided with fractural impressions. The fractural impression gives a controlled break at a selected position, while remaining parts after forced entry return to the original state. The training door further comprises a moveable frame 2 with openings for reception of locking cylinders 3a-e, 10. The frame 2 is resiliently suspended in the frame. In one embodiment, the resilient suspension is of varying strength at varying positions on the frame, in order to be able to resemble different kinds of real doors. The invention further relates to such a training door provided with a forward feeding key 9 arranged to be received in a fractural impression, for controlled forward feeding of new locking cylinder pieces. The training door may further comprise locking cylinders 10 that are resiliently suspended and arranged to be pressed against the door leaf when the door is forcibly entered, which resembles the properties of seven lever locks and nine lever locks at forced entry. The training door may further comprise a fling protector 8. |
