Ive been buying grommets for years, for various DIY projects at home. I chose these metal units for use in visible places. I had a little trouble getting the inner cover off. Usually easy, but this one has tabs that slip under other tabs to hold it in place. Turn it upside down and youll see it requires twisting to separate them. Then it pops out easily. Each arrived wrapped in plastic in a small cardstock box, , both in a plastic zip bag. There was no damage, and they feel quite substantial in my hand. What remains to be seen as how accurately they will fit the 2-inch hole size specified. Too small and you can always enlarge. But larger than the width of the grommets top will be a problem. If your hole is only slightly oversized, you can improvise a spacer and still use the grommet. Possibly cardboard strips, or you can wrap electrical tape around the part that sits in the hole until its snug. I recommend you buy or borrow a 2-inch hole saw. If you think youll be doing a lot of home improvement projects in the future, consider a set. Hole saws come in a range of prices and theres no need to spend big money for occasional use. Of course, you could try to make do without the hole saw, but this would be a mistake. It will be difficult to get a clean hole without it. I suggest you start drilling from the bottom side, until the bit is just high enough to break through the top. Then put the arbor bit into the same hole and continue drilling from the top. (You may first have to drill a small pilot hole from the top to mark the correct spot.) Make sure the saw is exactly perpendicular! This method will help you avoid ugly tear outs on your visible surface, which will leave you with pesky repairs, the worst possible outcome when drilling for a grommet. You may need to limit dust build up in the cut by backing out the saw as you go to blow out the dust. Caution: the saw will be hot! To mount on a drill, a hole saw needs an arbor assembly. Avoid hole saws that come as split circles meant to be slipped into a channel on the arbor assembly and tightened. I once used this type with bad results. Thats why its cheap. Get solid circles! I do recommend these grommets. They are of solid quality, nice looking, and offer multiple colors. A good value. Perfect for highly visible locations like desks and tables. And just one more tip: the 4 sets of 3 bumps on the bottom ring are meant to snug up the ring. You may need to persuade it into the hole to accommodate. This doesnt mean your hole is too small. I havent used the product linked below, but it illustrates what Im talking about for DIY newbies. It includes the arbor (though some reviewers say it doesnt.) https://www.ZeeBooth.com/LENOX-Tools-Bi-Metal-Arbored-Technology/dp/B004YK8DMY/ref=sr_1_18?dchild=1&keywords=hole+saw+arbor&qid=1626577143&sr=8-18
