Contactdoos GN 992-V25-M10 voor vierkante constructiebuis

Drive the insert bushings GN 992 in by using a soft-head mallet. Their lamellas bridge a production tolerance of the internal diameter or of the internal square of ±0.5 mm, allowing screws to be mounted in tubes. The dimensions match those of the construction tubes GN 990, but checking the tolerance position of the tube is recommended.
