Review on 🔧 Reusable Handi-Shim for Precise Construction Leveling and Plumbing by Rene Putman

These are the best spacers on the market. I used them to install a kitchen cabinet. First use the laser level and find the highest point on the floor by setting it as your height. Then connect about 3 base cabinets together and place them against the wall where they will be installed. Then take these spacers and stack them on top of your cabinets and add enough of them to just bisect the laser line. Do this around the back and front. Turn the cabinets over and screw the standoffs to the floor (pre-drill to avoid splitting the wood or adding padding to the floor). Place the cabinets back to the wall. Bam done. Perfectly smooth
