Can't remove the plastic cap from the corner jointUpdated a year 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 / hard to remove. If you find it's not possible to prise the caps off with fingers, we advised you make a small cut in the top of the plastic and then use pliers to pull the cap off. It does not matter if the cap is damaged, as it is designed to be thrown away.
