Spinlock TC50 – 6 Sheave High Load Deck Organiser (Symmetric and Asymmetric)
The Spinlock TC50 6 Sheave High Load Deck Organiser is the largest and most capable unit in the TC50 range, designed for yachts requiring maximum line-handling capacity under extreme working loads. Equipped with 50 mm alloy sheaves and a low-friction bearing surface, it provides efficient, durable performance for the highest-load halyards and control systems.
The alloy sheaves deliver outstanding stiffness, wear resistance, and heat tolerance, outperforming composite sheaves used in the T25, T38, and T50 organisers. This makes the TC50 exceptionally well-suited to performance yachts where halyard tensions and trimming forces are consistently high.
The Vari-camber base automatically follows the deck curve, ensuring a well-sealed and precisely aligned installation. Integral end fairings protect lines during side loading. Symmetric and Asymmetric variants are offered, with the Asymmetric version reducing footprint and weight for space-constrained layouts.
The TC50 shares a common footprint and mounting geometry with the T50 organiser, allowing the two ranges to be stacked for combined medium- and high-load systems.
Key Features
• Six 50 mm alloy sheaves for maximum high-load capacity
• Low-friction bearing surface optimised for extreme loads
• Alloy sheaves provide superior durability and wear resistance
• Integral end fairings ensure safe side loading
• Symmetric and Asymmetric body options
• Asymmetric version offers reduced weight and footprint
• Fully stackable with T50 organisers

Applications on Sailing Yachts
Best suited to advanced, high-load running rigging systems on larger yachts. Typical applications include:
• Full suites of halyards for mainsail, jib, code sails, staysails, and spinnakers
• Numerous heavy reefing lines and tack line arrangements
• High-load outhaul, cunningham, and vang systems
• Multiple furling and stabilised downwind control systems
• Mixed high- and medium-load organiser stacks combining TC50 and T50 modules
• Performance cruisers and race yachts with extensive deck layouts
