Allen high load thimbles summary

The use of high load, low friction thimbles where blocks may have been used in the past, has simplified areas of rig tensioning such as kicker or down-haul systems.

By splicing the thimble into a dyneema loop it allows far higher loads and enhanced performance.

These high load friction rings feature CNC turned 6082 aluminium, anodised, PTFE coated rings with safe working loads of between 300-1000kg.
