R2.1 e-tube: Cost-effective Cable Tubing for Chip Protection

Cost-effective, strong e-tubes with 26 mm, 40 mm and 75 mm inner height. Lids snap-open along both sides and can be removed. Very sealed design and strong double stop dogs for high fill weights and unsupported lengths.

Advantages of the R2.1 system:

  • Large inner height and therefore cost-effective
  • Cables are protected from swarf
  • Easy to fill, lids openable from both sides along the inner or outer radius
  • Low noise operation due to integrated brake
  • Separator notches integrated into the e-tube link and lid for side-mounted applications
