AFTCO's superb line of Big Foot Super Heavy Duty (SHD) roller guides feature rugged, roomy frames with unequalled knot clearance. Rollers and bearings are extra large and extra tough to endure the special punishment of this heaviest line class. AFLON, an exclusive *Teflon® formulation, is bonded to all bearings to provide lasting lubrication and protection. The oversized feet are precisely formed to match the contours of leading rods in this class, and they grip the rod with exceptional strength. The edges are “feathered” to allow winding thread to “climb” over the feet easily. A complete set of five includes the double roller stripper guide and two each of the two super heavy duty single-roller guides, graduated in size. AFTCO's Big Foot Super Heavy Duty (SHD) roller tip-tops are a perfect match for these guides.
