Lengths of guy ropes - user defined anchoring heights and distances

The calculator will work out the lengths of guys necessary for anchoring your mast. It will calculate for anchoring in either three or four different directions and one to six levels of anchoring. It assumes anchoring heights on your mast are placed evenly apart, and that the ground is level. The calculator “User-defined layout” permits you to select the exact guy anchoring heights and distances for your mast. --- Remember to include a surplus to cover any measuring inaccuracies and the thimble termination at either end. The calculator will show you the length of the guys needed for each level, and the total length required for the whole mast. --- You can study the results and decide if you want every guy to be an unbroken length, or if you want to save money and have joints. Jointing shorter pieces obviously uses the odd lengths more economically, but please do not even think of tying a knot to make a joint, do it properly with the correct hardware, otherwise a large part of the guy strength will have been lost. --- The calculator works out how many reels of guy you will need in total for whichever way you choose. All reels are 100m long. --- Use the “Forces in guywires” calculator to work out what strength guy you need, and then you are ready to order you new guys and accessories.

  • 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.)
