  • Camouflage ropes 2. 8. 2018

    We started production of "Camouflage look" of two sizes of Mastrant-P – called Mastrant-C. It is targeted for customers who need "invisible" guying in specific environment. The main color is tan with brown “dots”. They are available in sizes "3+" (3.5 mm, 9/64") and "6" (6.2 mm, 1/4"). 

  • New size of "P" rope: 3.5mm (9/64") 30. 7. 2018

    We started production of new size of rope Mastrant-P which fills the gap between "size 3" (diameter 2.6 mm) and "size 4" (diameter 4.4 mm). It is "size 3+" and has diameter 3.5 mm (9/64"). Breaking strength is 300 daN (about 300 kg or 660 lb.).  
  • Strength of P4 and P5 26. 4. 2018

    We are updating the ratings for Breaking Strength and Safe Working Load for our most popular rope, 4mm and 5mm Mastrant-P. We began improving the construction of this rope in our production process more than 6 years ago and have been testing samples from each run. We are now satisfied that the changes have resulted in consistent, permanent improvements. Here are the new ratings:
    Mastrant-P, 4 mm: BS=440 daN (about 440 kg, 970 lb.), SWL=132 daN (about 132 kg, 290 lb.)
    Mastrant-P, 5 mm: BS=540 daN (about 540 kg, 1190 lb.), SWL=162 daN (about 162 kg, 360 lb.)
