Measurement sheets and true-size gauges
True-size gauges and record sheets for the measurements a seller will ask you for.
This is the section a chatbot cannot replace. It can tell you what a belt marking means; it cannot lay a true-size 18.5mm bar next to the belt in your hand. Every sheet here that shows something at actual size also carries a printed millimetre rule, so a mis-scaled printout is caught before it produces a wrong number that looks right.
