This system ensures high reliability and allows up to 7 bands to be attached, providing uniform distribution of pulling force.

Technical Features

Frame made from stainless steel by laser cutting for superior mechanical strength and long-lasting durability
Pulleys with derlin bearings that ensure efficient smoothness and reduce friction during the loading phase
Pulley diameter: 22 mm
Pulley height: 5 mm

Benefits for Freediving and Spearfishing

Thanks to its balanced construction and the use of selected materials, the Hard 7 pulley block improves load distribution on the bands, optimizing swing accuracy and control while loading the speargun. The derlin bearing provides excellent fluidity and smooth travel, reducing effort and increasing band efficiency.
