The device includes at least one member for engaging the line to prevent unwinding rotation of the mandrel.

And those flange plates may be adjustably positioned on the mandrel to accommodate lines of differing widths.

Why it's free to use
- Filed May 1, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended May 1, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 1, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
