The Allen Articulating Double and Triple Dynamic Blocks are the only ones of their kind on the market. Each block articulates freely, allowing perfect alignment with the rope angle for smoother, more efficient movement under load.
Independent Articulation
Each block can move freely from the other, ensuring perfect rope alignment and reduced friction in any rigging setup.
High-Load Stainless-Steel Sheave
The stainless-steel sheave delivers faster rolling speeds, higher working loads, and lower friction than standard acetal sheaves. It is compatible with both rope and wire.
Advanced Bearing System
Allen’s patented Dynamic bearing system features twin rows of stainless-steel ball bearings running on a stainless-steel rail. This design ensures superior load capacity and long-lasting performance.
Ultra-Strap Construction
The Ultra-Strap, created through a coining process, strengthens the strap, increases wear resistance, and protects the rope. It was the first block in the marine industry designed specifically for rope attachment.
Lightweight Becket
A large central rivet reduces the overall weight and offers a rope-friendly tie-off point, ideal for cascade systems.
