It features a triple-sheave configuration, utilizing high compression strength Acetal ball bearings and a carbon black Acetal sheave to minimize friction. The block's construction incorporates fiber-reinforced composite materials in the block head, cleat arms, and beckets, contributing to its strength-to-weight ratio. This design is suitable for IT buyers managing equipment for operations requiring efficient rope handling systems. It addresses the need for reliable, low-profile components in environments such as mainsheet and spinnaker systems on dinghies up to 5 meters (16 feet), as well as halyard, vang, and backstay applications on similar sized boats. Additionally, it can be integrated into control line systems on larger yachts, providing a versatile solution for mechanical advantage and line management.
The Ronstan Series 30 Ball Bearing Orbit Block - Triple is designed for a maximum rope diameter of 8mm (5/16").
This block has a Maximum Working Load (M.W.L.) of 550kg (1,210lbs), making it suitable for demanding applications within its specified use cases.
The block features a high compression strength carbon black Acetal sheave and Acetal ball bearings. The frame and cheeks are made from toughened, glass fiber reinforced Nylon, and it includes a UV stabilized, multi-strand impregnated SK75 Dyneema link.
Primary applications include mainsheet systems and spinnaker sheets on dinghies up to 5 meters (16 feet), halyard, vang, and backstay applications on boats up to 5 meters (16 feet), and control line applications on larger yachts.
