I received this Jumbo Utility Hook as a free sample and wanted to use it to hold a larger gardening tool.  I have a vinyl-like shed without shelves.  I wanted to see if this could adhere to the side wall and hold the hedge clippers.  It definitely has done that and is still sticking even after a week of continuous very hot temperatures.  I will say that it's on the side of the shed that doesn't receive direct sunlight which might make a difference, because the small 3M wire hook I used on the side that does face the sun didn't hold and fell off when just holding a rag.
