More Information

The Mark 2 Version - Jimmy Green/Barton Low Friction Ring with Dyneema Loop 

The V2 variation is produced from Liros D-Pro 100% pure Dyneema® SK78 rope and a Barton Low Friction Ring.

However, the V2 features a Brummel lock splice to fix the Dyneema loop around the Low Friction Ring, creating a tight fit and a secure attachment.

The important difference from the Mark 1 version is that the Brummel splice method doubles the content of Dyneema in the loop section, and therefore doubles the diameter.

This makes the loop very strong and robust, but the extra diameter should be taken into consideration for your application.

The Brummel Lock Splice also makes the attachment to the ring more secure than stitch and whip seizing.

Jimmy Green low friction rings with Dyneema loop are Brummel spliced in-house by the Jimmy Green Rigging Team.

The Dyneema loops are produced to order, and therefore subject to splicing order lead times.

There are six sizes of Low Friction Ring, each with a Jimmy Green designated Dyneema diameter and loop length.

If you wish to specify a different diameter or loop length, please contact us via email and we can quote accordingly.
