Wiring Holes are 1.5 mm Dia. Tolerances are + 0.1 mm Material... Most softwoods are suitable.
Shallow commercial side bars
Non Self Spacing types of 22 mm or 28 mm straight sided form can be used with castellations in supers used for honey gathering.
Deep Commercial side bars
Only Self Spacing types are suitable in the brood box of this type of hive as the lugs are too short to accommodate metal or plastic spacers.
Note 1... I have seen versions of the deep Hoffman type frame sides with the wings 70 mm deep rather than the 55 mm shown in the drawings.
Note 2... It is common to use the ordinary B.S. Shallow type supers and frames in conjunction with Commercial brood boxes instead of employing commercial supers
