The frame includes a rectangular support frame provided with components for fixture purposes, and for attachment to a box fitted on a base. The components for fixing the support frame to the box comprise four holes or slots positioned in the frame so that the distance between two opposing holes is different. The support frame can partly be fitted on a standard type box, and partly by being rotated through 90 deg. about an axis at right angles to the plane of the frame. Counterposed holes or slots are pref. spaced 60 or 67 mm apart. (Provisional Basic advised week 85/06) |
