Joint? Really? Whoa, sorry flashback. Yea the rollers/hinge is hidden under the sliders carpet. Better plan on adding something to the floor of the slider. Raising the level and extending the floor to cover the hinge thingy. I'm planning to remove the booth and do the same mod this year so make sure you take a lot of pictures and let us know so I can blame you to my wife. Lol.
