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.

I. du Pont de Nemours and Company or its affiliates.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable
