later I used these to plug some wiring holes in my tractor's ROPS. There were wires coming out of the holes and I didn't want to reroute the wires so I cut them to fit. A small knife works great for this. The forks are flexible and hold tight. Even the case they come in is great, with secure clasps and a nice hinged lid. There are many sizes, so I will find many more uses for these wonderful forks.
