That open tube end is catching on everything and the whole corner looks half-finished. These black plastic end caps slide inside your 16 mm tube (20 mm outer) and close it off clean. Each one includes a line so you can route a cable or wire straight through. Pack of two, so you've got a spare when the first one's on the other side of the yard
