Fiddle block ratio

[coolbrze]

What's the ratio on this fiddle block, ? to 1, e.g. if I've got 3 guys pulling on it, b/c of the pulleys it would equal ? guys? Thx!

Those blocks work very well in tight situations where a truck winch or other means is unavailable. You will need two prussic loops and one to attach to bull rope and one to take up the progress at your anchor spot. Also a simple eye and eye rigging sling or endless sling makes a great anchor if a tree or something to wrap around is available. If something is not available a bucket truck, large pickup, or skid steer positioned works well.
