I bought cable in bulk from home depot with the aluminum fasteners needed to make them into what ever length I need to and used a hammer and anvil to make the loop. Will have to take picture tomorrow of the bulk items. as for locking them together, i feed one eye lit through the other eye lit of which ever one is next to it and bend it back on itself and then lock it. will also take picture of that tomorrow. as for the power pedestal, use the locking hole on the power box or wrap the cable around the pole under the power box and lock to itself. can't take a picture of that until i go camping unfortunately. hope this helps until the pictures.
