need ideas on light setup

[robalv]

there is 1/2 and 3/4 inch conduit straps some have 1 eye you want the one with 2 eyes
I think the 3/4 inch will work better for you so you would get the 3/4 EMT conduit along with 4 90* radius 4 or even 6 clamps and 3 10' 3/4 EMT to be safe you could always take back what you don't use also a hand full of 1-1/2" wood screws oh and 8 3/4 EMT connectors
now EMT is made to withstand weather I don't know how it will do with the saltwater. call if you need help 210-630-2774 you will also need a tubing cutter
