HYE tufnol yacht block
High-strength yacht and working block for the most demanding uses.
The white Polyacetal sheaves run smoothly over brass bearings. The black nylon housing is set on a solid stainless-steel 3-in-1 suspension that includes a shackle, which allows the block to act as a swivel block or to be set to hang parallel or perpendicular using an Allen-head screw.
The very high breaking loads have been tested by Germanisher LLoyd (GL). The Safe working load (SWL) is 50% of the given breaking load (BRL).
