Our High Performance blocks are developed with emphasis on design and strength. The blocks have aluminium ball bearing sheaves and are bolted together with allen screws for easy disassembling if needed.
The ball bearing sheaves in size 35, 45, 57, 75 & 100 have hub in PET (white). These sizes are also available with black delrin/PET plan bearing sheaves.
Size 35 and 45 are mounted with rivets and size 57 has rivets in the top.
