Antal Double Stopper Deck Block Ø65
Compact and versatile, the Antal Double Stopper Deck Block Ø65 combines two foot blocks with integrated jammers so you can divert and temporarily hold two lines before they reach the winch. Ideal for smaller yachts and control-line layouts, it frees up winches quickly while keeping side decks clean and safe.
Each 65 mm sheave is moulded from high-strength resin and runs on composite fibre bushes with side ball bearings for smooth, low-friction operation. Hard anodised aluminium side plates provide corrosion resistance; recessed fasteners and rounded edges keep the profile snag-free and comfortable underfoot. The lever is fully concealed within the side plates, and aluminium locking cams feature automatic opening springs—easing the line is sufficient to disengage the jammer. Available in port (L) and starboard (R) versions to ensure correct geometry and intuitive operation on either side of the boat.
