Holt Dynamic Blocks
Holt Dynamic Single Fixed

The Holt 20mm dynamic block range offers excellent stainless steel ball race systems for low friction performance.


More Information

The Dynamic bearing system features stainless ball bearings on a stainless axle.

The blocks also feature an open axle for easy line attachment and a full moulded jacket for sheave protection and impact resistance.

The 20mm and 30mm sizes also feature a cold forged pro-strap which gives a rope friendly attachment and greater articulation.

These blocks also have stainless steel cheeks with weight reducing windows.
