Antal Double Stopper Deck Block Ø80
The Antal Double Stopper Deck Block Ø80 is a versatile mid-size option, combining two foot blocks with integrated jammers. It allows you to divert and temporarily hold two loaded lines before they reach the winch, making it easier to free up winches and streamline deck layouts on medium-sized cruising and racing yachts.
Each 80 mm sheave is manufactured from high-strength resin and runs on composite fibre bushes with side ball bearings for smooth, low-friction performance. The hard anodised aluminium side plates are corrosion-resistant, with recessed fasteners and rounded edges for a safe, snag-free profile. The concealed lever design keeps the deck surface clear, while the aluminium locking cams feature automatic opening springs—simply easing the line is enough to release the jammer.
Available in port (L) and starboard (R) versions, this block ensures correct line alignment and intuitive handling whichever side of the boat it is installed.
