HARKEN 40mm Carbo AirBlocks®

From the folks who invented ball bearing blocks, this line of blocks boasts an excellent strength-to-weight ratio. The plastic in their sideplates, sheaves and balls makes them 30% lighter, 60% stronger and generally less expensive than equivalent conventional blocks.

Use the 40mm blocks for jib and mainsheet systems on high-performance dinghies, and for high-load control lines on small keelboats. The 40mm blocks handle loads similar to Harken's 2.25" blocks. Recipient of both the Dame Award and Sail Magazine's Freeman-Pittman Award for innovation

    Comments about Harken 40mm Sheave Diameter Block, Single/swivel Style, 485lb. Swl:

    I use this block with Harken Little Swivel Cam Base/150 Cam-Matic. I needed to ream the hole in the block swivel for the base attachment pin. Other Harken blocks may have been more compatible.

    Works like a charm!
