Block, heavy duty - 13 mm sheave
Details
Block, heavy duty - 13 mm sheave. SAILSetc design and manufacture. A beautifully simple design of block for lines of 0.1 mm up to 2.0 mm Ø - simply designed better.
13 mm sheave, 25 mm long, 19 mm wide, 9 mm thick, M3 fasteners.
Engineered for use in the main winch loop system on boats with large rig loads that typically use the RMG380 winch which may give rise to very high loads. Suitable for A Class and larger boats and lines of any diameter up to 3 mm. For smaller boats use 61-008 or 61-010.
The housing for the sheave is designed to prevent fouling of the line even when it is very fine. This makes it distinct in operation from micro-blocks designed for dinghies which usually foul when used with lines smaller than 2 mm Ø. The whole unit can be taken apart safely for maintenance.
SAILSetc blocks have black plastic bodies, which may be injection moulded, turned, or printed. The sheaves are stainless steel, but not marine grade stainless steel, and have hardened rust-resistant balls. Fasteners provided are marine grade stainless steel. Other metal parts, if any, are marine grade stainless steel.
Maintenance of the bearings used in this product is described here.
