working load, and directional arrows 
for line direction.
Protexit Blocks
When you race HARD, and you rip through as many hoists and douses as we 
do sailing W-L legs all the time, you should expect to start wearing through the 
sideplates of your halyard exit block right? Wrong! 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 higher working loads than any small boat 
exit blocks we’ve ever made. Protexit aluminum sheaves rotate on sleeve 
bearings with Delrin® sideload balls so they don’t deform in extreme 
conditions, while reducing wear on the halyard, too.
Strong. Durable. Gentle. Protexit blocks protect the race results you work 
hard to achieve.
