50MM BLOCK - TRIPLE

A2059 – 50mm Quint Dynamic Block | Low Friction Mainsheet Block for Sports Catamarans & Keelboats

The A2059 50mm Quint Dynamic Block is a high-performance ball bearing block specifically designed for low friction mainsheet systems on sports catamarans, while remaining perfectly suited for a wide range of other applications, including backstay tensioning on keelboats.

Patented Bearing System – Dynamic Block Technology Dynamic Blocks feature an exclusive patented bearing system using twin rows of stainless-steel ball bearings running on a stainless-steel rail. This delivers superior load-carrying capacity and outstanding longevity compared to conventional bearing systems on the market.

Swivel Lock – Flexible Orientation Control The A2059 comes with a removable swivel lock moulding. When installed, the shackle can be securely locked in 90-degree orientations. When removed, the attachment shackle spins freely for maximum rigging flexibility.

Becket – Lightweight & Rope-Friendly Attachment The large central becket hole reduces the overall weight of the block while providing a rope-friendly attachment point for easy and reliable rigging.
