OTS Protective jacket™: Patent no: 314459

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





  • 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.

OTS Chafe Gear™

OTS Chafe Gear™ has been used by operators in the marine and oil & gas industry for over a decade, and lately it has also become more common in the fishing industry. The durable construction with its high abrasion resistance is demonstrated daily. 

There are two types of OTS Chafe Gear™; a sleeve without axial velcro which is used prior to and during splicing of the rope, and a sleeve with super strong velcro which enable assembling of the sleeve anywhere on the rope without re-splicing. The chafe gear is also fitted on chains and other hardware to protect sorroundings from chafing against the hardware. 


  • Ears for fastening of seizing rope 
  • Velcro locking straps in the ends and/or mid-sections of the sleeve 
  • Loocking hoops
