Fiberglass reinforced roller with Teflon® sleeve
The shackle diameter is 6 mm and the bolt diameter is 8 mm, which provides optimal strength to weight ratio.
This is a lightweight yet durable boat pulley used to guide ropes and reduce loads on sails, hoists or winches, for example. The fiberglass reinforcement increases strength and rigidity, and the Teflon® sleeve reduces friction and improves rotation sensitivity.
