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