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.
