20mm Back-to-Back Dynamic Block — Dual Opposing Load Performance

The A2028 features sheaves facing opposite directions, allowing two control lines to run at a maximum of 180° to each other. This is a highly popular choice for spinnaker launcher systems (common on 49ers) and triangle backstay systems on sports boats.

High-Strength Structural Design

Built with a strong stainless-steel side strap and durable nylon mouldings, this block is designed to stay together even under high opposing loads. The "V" shape allows for secure lashing around the middle.

Hollow Central Becket

The large central rivet reduces overall weight while acting as a rope-friendly attachment point (becket), perfect for tie-offs in cascade systems.

Patented Dynamic Bearings

Equipped with twin rows of stainless-steel ball bearings running on a stainless-steel rail for superior load-carrying ability and longevity compared to plastic-rail designs.
