You connect the bottom piece to the wall, it will work if you don’t connect it but it will be more secure. I love that it’s all metal! Very clear directions to set it up

Y’all this thing is brilliant. I mean you just screw it in place and then boom slide it in out when needed. Oh, crazy aunt Helen needs some planko mix but her ol raggedy tired behind don’t wanna look too hard for it? Well she can just slide that thing on out, grab that batter-baby, and press that life alert button afterwards cuz she’ll be done after that.
