Winches are subject to wear and tear. Proper maintenance is essential for the life of your winch. Protempo supplies pendulums for maintenance or repair of Fulton or Protempo-branded winches. For most Fulton types, these pendulums are immediately available from stock: pendulum lengths of 6-8-9-10 or 11 inches. Pendulums are also available for the 530A and 950A winches.
