Allen Blocks


High Load Thimbles


Allen brothers have expanded their range of high load alloy thimbles; the new range is available in a series of eye catching colours and various sizes which can easily be customised.

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.

In conjunction with Dyneema® lines, they allow far higher loads and enhanced performance. The new Allen range of HL thimbles feature CNC turned 6082 aluminium, anodised, PTFE coated rings with safe working loads of between 300-1000kg.

Aluminium Colours: black, blue, gold, orange, purple, silver
