There's a long plastic (probably polypropylene) bar, with a curved top, that the kitchen slide in the 3400 runs in and out on. That, and the vertical adjustment on the outboard end of the slide, determine what will fit under it.
When I put laminate flooring in the kitchen, I lowered the vertical adjustment all the way when the slide was a little more than halfway out (MIMF's suggestion). Then I used a full length 4x4 up close to the frame to support the slide when it was all the way out as I jacked it up about an inch (NOT MIMF's suggestion). I carefully monitored the amount of room at the top of the slide so I wouldn't damage the wall or slide at the top. This let me get one hand under the inside of the slide to see how much room I had to work with. It was very close. If I could have found a laminate thinner than 5/16, I would have used that.
It was sometimes frustrating to get the laminate cut properly and fit into the tight spaces in the kitchen, but it worked. I still have to caulk the spaces around the edge of the laminate to prevent liquids from getting in under it. I think a 1/4 inch space is plenty considering the short length of the laminate, though.
I reset the vertical adjustment to about half its full travel (MIMF's suggestion). If I could have figured a way to get a piece of 1/8 inch plastic sheet on top of the bar, I would breath a bit easier whenever I move the slide in or out. It came out nice, though, and was worth the effort.
