Just got back from 4 day trip and tried my new Clip on Tarp Pull Outs that I picked up from Dutch. It rained for a day and a half along with gusty winds. These pullouts held all weekend and and no ill effects on the tarp when I removed them. Nice addition for your tarp if it doesn't have installed pull outs, for a great price.
