90 mm Synchro Footblock

Optimized block geometry and a revolutionary free-spin bearing combine to reduce friction and improve efficiency over conventional blocks. Synchro Footblocks feature alloy cheeks, fixing isolators and a molded base plate to prevent sealant ingress into the sheave.

• Standard and jammer footblocks can be double stacked
• Optimised jammer shape holds line central on the sheave
• Tough alloy cheeks
• Synchro sheave loads match the same sized blocks
• Twin fixings with inserts
• Wide head for a solid base, block will not “roll” on the deck
• Moulded base plate with recess to hold sealant around fixing screws and prevent ingress onto the bearing and sheave
