40MM BLOCK (2 BLOCKS CONNECTED)

A20401S-2030 – 40mm Dynamic & 30mm Dynamic Linked Single Blocks | New 2023 | High-Performance Linked Blocks for Keelboats & Dinghies

New for 2023, the A20401S-2030 40mm & 30mm Dynamic Linked Single Blocks are built from high-strength, lightweight glass-loaded nylon and combine Allen's renowned dynamic bearing technology to deliver a high-performance solution perfectly suited for keelboats and dinghies.

Ideal for use on main, jib and spinnaker sheets on dinghies, as well as keelboat control lines, this linked block combination is the perfect choice for mainsheet systems, spinnaker systems and pole launcher systems.

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. The ball bearings are caged for further friction reduction, delivering superior load-carrying capacity and outstanding longevity compared to conventional bearing systems on the market.

Linked Blocks – Minimal Snagging, Maximum Reliability This combination links a 30mm traveller block and a 40mm mainsheet block as closely together as possible, resulting in a minimal risk of snagging or failure. The linked configuration is equally well suited for spinnaker and pole launcher systems, offering a clean and reliable setup on board.

Becket – Versatile Tie-Off Point The 40mm block features a large central hole that can be used as a becket tie-off point for added versatility.

Please note: Maximum working load is rated to the A2030 block
