Description
When you race hard, and you rip through multiple hoists and douses, you might expect to start wearing through the sideplates of your halyard exit block.
But thanks to Harken Protexit™ blocks, wear from side angle loading is not inevitable.
Protexit’s all-aluminum, wear-resistant housing carefully ushers line in and out no matter the angle.
There’s more: Protexit blocks offer Harken's highest working loads for any small boat exit block they make.
Protexit aluminum sheaves rotate on sleeve bearings with Delrin® sideload balls so they don’t deform in extreme conditions
They also reduce wear on the halyard at the same time.
• Strong, durable unibody top/side plates - hardcoat anodized forged aluminum
• Sculpted top plate - protects sheave and won't snag lines
• Tough sheaves - machined from hardcoat anodized solid aluminum
• Proven bearing system - composite sleeve bearing with sideload ball bearings
• High load drop-in replacement - 30 mm blocks replace Bullet® blocks
Harken Tip - When selecting line diameter, use one size smaller for smoother running blocks.
