This Harken 29 mm double bullet block is a compact and lightweight block for control lines on sailboats where low friction and quick response are essential.
The block is constructed with free-running Delrin ball bearings, UV-stabilized sheaves, and carbon-reinforced sideplates, which provide efficient trimming and reliable performance under load.
Stainless steel reinforcements with rounded edges contribute to a robust solution for marine use, while the low weight makes the block well-suited for performance-oriented sailing.
