Specify TB25 with 104/5.0 or TB31 with 104/5.08, followed by a two-digit pole count from 02 to 24. The standard 104/5.0 drawing uses suffix Y000A, where Y is the colour code. The general legend also identifies screw-head code 0 for slot and 1 for cross, and screw-clamping code 0 for screw down and 1 for screw up.
