Custom urethane liners provide the best protection, stability, & function for irregularly shaped residual limbs or when sensitivity or scarring is present.

  • Specialized polyurethane formula provides improved tear and puncture resistance while maintaining the “floating” characteristic that provides protection, stability, and function
  • Special coating is easier to clean and has a long history of skin safety
  • Non-stick treatment delivers greater liner consistency and easy use
  • Usually used in combination with a sealing sleeve and valve or with the Harmony vacuum volume management system, but also available in locking
  • Suitable for patients at all activity levels with a sensitive, bony, or scarred residual limb
  • DVS suspension option now available on Uneo Unique custom liners
  • Ottobock FREE Custom4U Scanner App now available for iPad/Structure scanner (see instructions in Documents tab)

Serial number location: To find serial number, invert liner inside out and look at the distal end for the laser etched information. Talc powder rubbed on etching may help to read.
