⁽¹⁾ The lengths listed are standard; other lengths are of course available. The maximum lengths are listed on page 48.

⁽²⁾ B designates the width of a single guideway. B₂ designates the width over both guideways.

⁽³⁾ Select accessories as follows: cage types on pages 49 and 50, end pieces on pages 51 and 52, fastening screws on page 52.

⁽⁴⁾ The catalogue prints 1007 g, which breaks the column’s regular increment of 915 g per 100 mm (the pattern gives 10065 g). The printed value is reproduced here as-is; please confirm the actual weight with the manufacturer.
