50MM BLOCK - SINGLE

A2050 – 50mm Single Dynamic Block | High-Performance Sailing Block for Keelboats & Catamarans

The A2050 50mm Single Dynamic Block is a premium ball bearing block engineered to minimize friction and allow ropes to run at maximum speed, even under heavy load.

Perfect for keelboats and catamarans, this versatile block suits a wide range of applications — from jib sheet to mainsheet systems and everything in between.

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 – Effortless Orientation Control The block head incorporates a swivel lock mechanism: simply turn the locking screw to either fix the swivel at 90-degree orientations or release it for full free-spinning rotation, giving you complete flexibility for any rigging configuration.

Becket – Lightweight Design & Versatile Attachment The large central becket hole reduces the overall weight of the block while providing a rope-friendly attachment point. Ideal as a tie-off point in cascade systems for smooth and reliable load distribution.
