12″ by 12″ interlocking bar mat by San Jamar. These interlocking mats are versatile. Multiple mats can be joined for larger areas and they are flexible and easy to cut to shape. Allows for airflow under glassware. NSF certified.
I purchased a number of these in 2015 and have since found them very handy. I use them for drying brew day gear and glassware and also underneath my fermenter in my fermentation deep freeze to improve airflow and keep the fermenter out of any condensation that might show up). I also use this in bottom of my kegerator. More info on that here – Upgrade Your Kegerator – 6 Improvements
