Review on Wolfride 180Pcs Grommet Assortment: High-Quality and Diverse Grommets for All Your Needs by Kevin Taharka

I bought this box for 1 inch only. I keep looking at the jacks here and trying to find the actual size chart in some of the sellers listings and they don't show anything about the detailed sizing. At least this seller has real sizes. Their 1 inch 1 9/32 outside size will work with a 1 1/4 wood drill bit and the fit for the 1/8 inch plywood ply is good. The quality of the rubber is normal, I gave it 4 out of 5, the quality is average, it works well.
