Another really neat fabricator innovation, these clamps line your sink up and clamp it in place during fabrication. The clamps themselves are made of a special polypropylene that adheres to hot melt glues but not to joint adhesive. The idea is to set the clamps around the bowl for placement and hot melt them in. Remove the bowl, apply joint adhesive and replace the bowl using the clamps for alignment. Snug up the thumb screw and you’re done. When the adhesive sets you simply knock off the Romy Clamps and they’re ready for the next job. The set includes 16 clamps enough to set one double bowl sink or two vanity bowls.
