Review on Industrial Hardware: Black Plastic Flush Mount Caplugs by Brian Cooper

This fits my needs perfectly. I used a hole saw to drill 2" holes in the bottom of all my very dark colored custom kitchen cabinets and these end caps snapped securely into place. I did this for a number of reasons as I once had a water leak and ended up cutting out the back of a cabinet to look for it (the reason I now have a flexchamber) and it will also allow me to use yearly as a part my house maintenance They have worked so well that I continue to install them throughout the house wherever I have base cabinets.
