60mm X2 AutoRatchet with Wave Sheave

The most effective way to increase friction is to add sharp edges to the ratchet sheave, but this quickly deteriorates and wears away the rope. So, after working alongside leading rope manufacturers the Allen design team came up with a simple solution which improves grip without chewing away at your expensive rope.

The Wave sheave has an offset V-style grip, made from hard-wearing recycled plastic nylon, which does not have sharp edges that will eat into the line. Instead, by adjusting the V formation in the sheave to be slightly offset, the ratchet now grips the line at additional points around the sheave, resulting in more grip.

The wave sheave not only improves grip but as a result of the design it also allows for a less ‘jumpy’ feel when easing the sheets.

Wave Sheave – The wave sheave offers 20 to 40%* more grip without adding any additional wear to the rope. We recommend pairing this ratchet block with 7mm Excel Marstron Plus.

X2 – “X2” is our ingenious double pawl system, designed to increase the longevity of the ratchet mechanism. Unlike other ratchet blocks our X2 pawl system allows the load put on the internal mechanism to be shared between two pawls. This results in a longer-lasting and more reliable ratcheting mechanism that can withstand higher loads.

Swivel Lock – The swivel can be locked in 90-degree orientations with the small black swivel lock at the top of the block. Alternatively, the swivel can be set to spin freely.

Trigger Load – The AutoRatchet mechanism is designed to engage at 10kg with a line wrap of 180 degrees around the sheave.
