Cutting holes for large grommets
Photo 1: Punch the hole
Mark the desired location of the grommet. Slide a wood block under the tarp mark and align the hole cutter over the mark. Strike the hole cutter sharply with a hammer until it punches through the tarp.
Photo 2: Position the grommet
Set a grommet on the anvil. Push the tarp hole over the grommet post and then slide the washer (rounded side up) on top.
Photo 3: Hammer the grommet together
Position the punch into the grommet tube and through the anvil center. Strike the punch firmly with a hammer. Rotate the punch a quarter turn between blows until the grommet and the washer fit tightly together.
Grommet kits include an assortment of grommets in several sizes and all the installation tools required. Kits are available at hardware stores and home centers. (We used 1/2-in. grommets for this repair.)
Determine exactly where you want the grommet and mark the location. The hole cutter in the kit has a beveled edge that cleanly cuts a grommet hole in the tarp (Photo 1).
Then sandwich the grommet and washer around the tarp and pound them together to complete the grommet (Photos 2 and 3). Make sure the punch is completely inserted through the grommet post and into the center of the anvil. Otherwise, the grommet and washer won’t seat together fully and the anvil may be damaged.
