The AFTCO Spin Strap should be used with the Maxforce Shoulder Harness, Maxforce 1 Harness, or Maxforce XH Harness. This will maximize the leverage when fighting fish. Wrap the Spin Strap around the rod foregrip and Velcro them together, then attach the D-Rings to the harness clips. Designed to wrap around the foregrip of a spinning rod. Two D-rings attach to harness snaps for added pulling leverage when using spinning tackle. Special tacky material prevents slippage.
