The patented chafe gear - OTS Protective jacket™ - offers excellent protection against external abrasion and increases rope lifetime with up to five times. The "no-rupture" construction combined with the worlds most abrasion resistant synthetic fibers, makes this the best cut -and abrasion resistant cover for your ropes. The jacket is mechanically braided onto the rope for a firm and solid finish.
OTS Protective jacket™ is braided in the following combinations:
- Soft eyes
- Soft eyes and required length (for instance over the splices)
- Exposed area on the rope
- Entire rope length
