This wood block with shackle and swivel is a double-sheave block with a 100 mm (4") sheave, designed for 12-14 mm rope. A classic solution for tackles and running rigging, where low friction and stable rope guidance are required.
The block is suitable for use on board for trimming, outhauls, lifting, and other deck tasks, where a robust block with a swivel provides flexible load direction. Fits well for both leisure boats and smaller tasks in the harbor and on deck.
