Awesome, thanks. I'll probably do what Shane G did for the round stuff and stuck and magnets on the square stuff direct. I just ordered 50 so that should sort me out for this year.I have 5 rare earth magnets over a 4 metres and they are stored on the patio on the side of a steal beam no problems. You can always add a couple more. One big thing I found with those magnets is do not do them up really tight as the break very easily.
