injection-moulded scale 602

Trihedral 300 mm ratio scale is made from white polystyrene. Hot stamping technology is used to imprint the 1:20, 1:25, 1:50, 1:100, 1:200, and 1:500 scales. Scale accuracy 0,2% of length. For easy distinguishing the sides are identified with yellow, green, and red colour strips. This makes the trihedral ratio scale pre-determined for use mainly in engineering professions. Packed in clear transparent polyethylene etui with paper insert and EURO hanger.
