Holt Allen's 20 mm Dynamic Micro Blocks are dynamic ball bearing blocks with line-friendly contours and articulation.
They are built to handle maximum loads and are designed to accommodate control lines through lead blocks, vang cascades, cunningham systems, halyard leads, and other tight spots.
All sizes have stainless steel cheeks and feature a central hole that can be used for a tie-on becket, which makes them ideal for Laser cunningham and vang systems.
