Thanks
I made a couple calls this am and it appears a 4200 lb breaking strength is 840 lb working load, 1/5th or 5x which ever way.
Always little things like these pop up,. but your statement about safety was my concern.
There was mention here some where about a pulley to lift the net up on the wall when we pull it back to hang it, can you advise on that again.
When we are finished will advise.
thanks
