Spinlock TWR Sheave Range
Best high-load line diverter for performance sailors needing deck-friendly hardware.
The Spinlock TWR Sheave Range is an evolution of their successful TSR Organizer Range, designed to function as a high-load, single-line diverter capable of handling lines up to a massive 2.5 tonnes. This organizer features a low-profile rotating sheave with a faired-in static top plate for a sleek look on deck. It is available with a single sheave in either 30mm or 44mm diameter. Key components include a hard anodized sheave and top plate, a stainless steel axle (with titanium parts available for weight reduction), and a high-grade polymer bearing. Installation is straightforward with a single fastener, and the wide base helps dissipate load effectively through the deck. It's also competitively priced and designed for simple on-deck servicing.

Know before you buy
The TWR range is specifically engineered as a high-load, single-line diverter. While it shares the DNA of the TSR line, it is optimized for handling significantly higher loads—up to 2.5 tonnes—making it better suited for heavy-duty line management.
Yes, the standard TWR comes with a stainless steel axle, but you can opt for titanium components if you are looking to shave extra weight off your deck setup.
The TWR features a wide base design that effectively spreads the load across the deck surface. This prevents localized stress points and ensures the hardware remains secure even under significant tension.
Not at all. The TWR is designed for simple on-deck servicing, meaning you can access and maintain the internal components without needing to remove the entire unit from the deck.
The sheave itself is rated for a maximum load of 2.5 tonnes. When dealing with a 30-degree deflection, the system can handle a total line load of up to 5 tonnes.
