Aftco's Wind-On guide set is specifically designed to accommodate the knots and connections of wind-on leaders, which have become increasingly popular for big game fishing. The guides will handle lines from 30 lbs. to unlimited line class, and they have the same knot clearance as our BF guides, but in a more compact frame. They will easily handle bulky wind-on leaders up to 700 lbs. test, and they are also available with ball bearing assemblies for the ultimate in line protection and performance.
