I am a retired 52/yr member of Steamfitter/welder NYC and I purchased the 32” x 48” x 5/8” hole, for my home hobby/welding shop and included this upgrade for additional Fixturing, this products are impressive in their quality, just having them in my hand I Ken told is so superior to some of the other products I have used in my career, the table is also equally impressive in person, and I must say better than I was expecting for the money I paid compared to most of the products on the market, sure wish I had purchased this much much sooner. 👨🏭
