GN992 Insert Bush, Aluminium, for Construction Tubes GN990
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.
