Just make sure you place it against the metal bracket on the slide.
During my walk-through the tech brought the slide in and commenced placing it between the wall and the top corner of the slide...against the wood trim. As he torqued it the trim starting cracking and bowing!!!!
I was like, "Whoa, whoa, whoa!" I asked if there was a piece of metal or a bracket or something it was to go up against. Sure enough it was along the bottom corner near the floor.
Also, if you don't use the slides for a month at a time press the retract buttons for a few seconds. Slides tend to creep out after time.
