AFTCO SHD swivel tops are designed for heavy wire line fishing and also work great as teaser rod fishing roller tops. Swivel tops are designed to keep the wire line in the center of the roller – so it touches only the roller and the Fuji Ring in the bail – eliminating wear on the sides of the frame. AFTCO swivel tops are equipped with our super-braided line compatible modified rollers and they are virtually foul-proof, and feature AFLON bearings for superior performance and lasting lubrication.
