A CRT device comprises a CRT unit 11 and a base unit 21 on which the unit 11 can be adjustably positioned. Feet 18a, 18b on unit 11 slide on front and rear ramp portions of double ramps 20a, 20b. Each ramp portion has flanges at its sides and bottom end, and the front ramp portions have five indentations to give five positions for unit 11, between which it can be moved by gently manual pressure forwards or backwards. …<??>The feet 18 may be formed at the corners of a rectangular frame which can be stuck to the unit 11. The frame may be split into two half-frames, and the base unit 21 into two half-units, which can be bolted together to adjust the length to fit different CRT units. |
