Using these sheets

Each sheet carries a dimensioned drawing, a size table with spanner sizes, the property classes, and the notes that matter in practice — where a standard has changed, where two spanner sizes exist for the same nominal size, where a substitution looks reasonable but is not.

Every sheet prints to A4 on our letterhead, so it can go straight into a tender file or up on a workshop wall.
