Spinlock TC50 – 4 Sheave High Load Deck Organiser (Symmetric and Asymmetric)
The Spinlock TC50 4 Sheave High Load Deck Organiser provides a robust solution for routing four highly-loaded lines aft on performance cruisers and race yachts. Using 50 mm alloy sheaves and a highly efficient bearing surface, the TC50 delivers low-friction line handling under sustained, elevated tensions while maintaining long-term durability and reliability.
The alloy sheaves represent a key advantage over composite designs in the T25, T38, and T50 ranges, offering improved heat dissipation, stiffness, and wear resistance during repeated high-load cycles. The Vari-camber base conforms to curved deck surfaces, improving installation accuracy and seal integrity.
Integral end fairings manage side loading safely for cleaner line entry and exit. Both Symmetric and Asymmetric variants are offered, with the Asymmetric version reducing deck footprint and overall weight. The TC50’s mounting geometry matches the T50 organiser, allowing both ranges to be stacked together to create mixed-load control banks.
Key Features
• Four 50 mm alloy sheaves for high-load multi-line routing
• Efficient bearing surface reduces friction and winch effort
• Alloy sheaves provide superior strength and wear resistance
• Integral end fairings allow safe side loading
• Symmetric and Asymmetric variants
• Asymmetric body saves weight and deck footprint
• Stackable with T50 organisers
• Vari-camber base follows curved deck shapes
• Safe Working Load (SWL): 1500 kg
Applications on Sailing Yachts
An excellent choice for yachts with several high-load lines. Typical applications include:
• Suites of halyards for main, jib, code sails, and staysails
• Multiple heavy reefing lines
• High-load outhaul, vang, and cunningham systems
• Routing furling line take-offs for large headsails
• Mixed-load banks combining T50 and TC50 units
• Larger performance cruisers with complex deck layouts
