Aftco Guides line of Wind On roller guides features rugged, roomy frames with unequaled knot clearance. Rollers and bearings are extra large and tough to endure the special punishment of this heavy class. Aflon, an exclusive Teflon formulation, is bonded to all bearings to provide lasting lubrication and protection. Aftco's Wind On roller guides feature oversized feet that are precisely formed to match the contours of the blank and grip the rod with exceptional strength. The edges are feathered to allow winding thread to climb over the feet easily. The Big Foot Super Heavy Duty roller tip-tops are a perfect match for these guides.
