发明名称 PULL-OUT BLANK IN A SHEET METAL CABINET WALL
摘要 A pull-out blank for creating an opening in a cabinet wall (1) is composed of a pair of parallel-running score lines (2, 3) surrounding the blank proper. The strip (4) defined by the score lines (2, 3) is transversely scored in at least one place (5), providing a weak spot that may be punched with a pointed tool in order to force one end of the strip (4) away from the sheet metal (1). A pair of pliers may be used to pull the strip (4) out of the cabinet wall (1), whereby the blank proper is also removed.
