These little pully block stainless steel pullys are the perfect size for what i was looking for.. We use them for fishing on our boat.. for big lines. and they are also useful for rigging the cables in the garage door opener. So they were just what I was looking for. They are strong and sturdy, and great quality. Because they are made of stainless they willnot rust which is great becaujse we will be using them in the elements! overall I am very satisfied!
