I was thinking outside the box when I ordered these! We don't use a detachable table in our RV, so that leaves two holes in the floor, each about 2-1/4 inches. I started with just a mat to cover the holes but with dogs that can be pushed aside. Ever since we've had dogs, there has always been a concern that they might step or slide in the pit and injure themselves. So so. I was looking through the RV blog where people were talking about trying to fill a hole and someone mentioned a plug and I just thought about it and found the exact size I needed! These plugs fit snugly in the hole, but can still be removed if necessary. They were sent quickly and I love that they end up with 2 more in case they get lost or whatever. Thanks for solving my dilemma!
