Antal Double Stopper Deck Block Ø100
The Antal Double Stopper Deck Block Ø100 combines two high-strength foot blocks with integrated jammers, allowing you to divert and temporarily hold two loaded lines before they reach the winch. This space-saving design is ideal for freeing up winches quickly and simplifying complex deck layouts.
Built with 100mm resin sheaves running on composite fibre bushes and side ball bearings, the block ensures smooth operation under load. The hard anodised aluminium side plates are corrosion-resistant, with recessed fasteners and fully rounded edges for safety and durability. The concealed lever design keeps the deck profile clean and snag-free, while the aluminium locking cams feature automatic opening springs – easing the line is enough to disengage the jammer.
Available in port (L) and starboard (R) versions, the Stopper Deck Block ensures correct line alignment and intuitive operation on either side of the boat.
