These are the "Rolls Royce" of roller guides - costly perhaps,but simply the finest ever made. The ball bearings are satellite quality,and precision-built to the tolerances only AFTCO guides offer. AFTCO ball bearing roller guides,with the same unequalled knot clearance of other Big Foot® guides,are available ONLY with the rollers,pins and screws in a Gold titanium nitride finish,but with frames in your choice of Gold,Black Chrome oxide,or our traditional Chrome-plate finish. This is a precision built product,and the only maintenance required is a wash-off with fresh water. Big Foot® SHD Ball Bearing roller tip-tops are the match for these guides.
