The 15mm Dynamic Block Range is the latest evolution of Allen's super low-friction dynamic technology, delivering exceptional performance in an ultra-compact design.

Constructed from glass-loaded nylon and featuring stainless steel ball bearings running on a stainless steel axle, these small but mighty blocks are perfect for lightweight control systems, sail integration, and soft-attachment rigging solutions.

A soft-attachment version with a Tii-through hole for up to 4mm rope and a breaking load of 240kg.

They’re ideal for take-up systems, low-load controls, or anywhere that demands smooth, efficient line handling in a compact package.
