20mm Dynamic Block

 

Other products by Allen

The Allen 20mm dynamic bearing block is simply the best designed and engineered micro block on the market.
  • Line friendly soft contours and articulation
  • stainless steel cheeks and inner bearing systems handle maximum loads
  • central hole for tie-on becket
The new Tii Block range is a perfect example of product development driven by customer feedback.

A rope friendly, smooth stainless steel ring in the top of the block holds it together providing maximum
strength and durability under load whilst completely eliminating block capsizing.

Furthermore, the Tii range is 20-30% lighter than the equivalent standard block and still features our
patented dynamic bearing system.
