  • Mastrant-Q 2. 2. 2020

    In 2019 we have developed replacement for “thick” ropes Mastrant-P. The line of diameters 6-8-10-12-14 will be replaced by new ropes Mastrant-Q with complex cores (Polyester and Polypropylene fibers) in diameters 6-8-11-14. These new ropes belongs to CLASSIC class and are even less expensive than Mastrant-P. Details.
