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
OTS Protective Jacket™
- Made with HMPE or polyester fiber.
- The OTS Protective Jacket™ comes out as a clear winner in comparative testing of abrasion and cut resistance.
- Excellent protection against wear and tear.
- Patented technology
Advantages
- Increases service life.
- Can be braided onto entire rope or exposed areas.
- Prevents rope from twisting.
- Protects rope from external abrasion.
- Reduced size of mooring line.
- Reflective material can be woven into jacket band for better visibility.
- Jacket band can be delivered in any colour.
