I made a light pole, which clamps on the camp site table. Has a light at the top and a GFI for outlets near table top. Since winter is starting to set in here in the mid-west, we're already researching out next get away. Long story short, we will be hitting more COE parks this trip and many have the concrete cast tables, on which my clamp doesn't fit. I need to revise the clamp opening, possibly by using a larger clamp and lost my measurement of the concrete table thickness in the typical COE park.
Any one got a tape handy? Thanks
