Can't remove the plastic cap from the corner jointUpdated 21 hours ago

We add black plastic caps to the open tube ends of our corner joints to help prevent damage during transit, and sometimes these caps are a little tight or hard to remove. If you find it's not possible to pry the caps off with your fingers, we advise making a small cut in the top of the plastic and then using pliers to pull the cap off. It does not matter if the cap is damaged, as it is designed to be thrown away.
