My sliding glass door frame sticks up 3-3/4" from the finished floor in my living room and 2" above the entryway deck outside. I'm looking for creative ways to make this transition less dangerous for tripping on.

  • Yeah, most sliders are hopeless on the ADA front, and the ones that aren't are only available as architectural spec/commercial hardware, not through normal builder channels AIUI Commented Sep 19, 2023 at 4:13

    Can you raise the entire deck? Or will that create a problem with the deck stairs that we can't see? Can you cut back the threshold to the door so there aren't two places to trip and a ledge too small to stand on?

    The problem with putting residential sliders at floor level is the dirt that fills the track ruins the cheap wheels even faster than if a small ledge keeps some of it out.

You can't. Any sloped ramp shallow enough to prevent trips will necessarily be several feet deep, creating an even more awkward situation in your room.

Post a sign. Color the ledge in a contrasting manner. Remind guests.

  • You'd need a 3-4 foot long ramp if you're shooting for commercial ADA compliance, but that's almost certainly overkill. A 1-foot ramp with a 1:4 slope may not be out of the question depending on room layout. Not sure at what steepness the ramp just becomes the tripping hazard, though. Commented Sep 19, 2023 at 13:52
  • Yeah, that's not enough slope to prevent trips. A shoe's rubber sole will catch on it almost as readily as it will currently if the wearer is unaware of the ramp.

Lock the door! That'd work right? No traffic = no tripping hazard. Not the answer you want?

What you have is basically cursed, move the door down by 2".


Bevel one edge of 1x6 or 3/4 inch plywood and fasten to floor. It’s non standard looking. We did this for wheelchair access.

    That's a very different problem than a trip hazard, and I'm not sure how it even begins to address a 4" ledge.

  • Thanks for responding. They have 1.5-2" of lumber plus about the same of door track. We added layers of lumber to reduce the changes to 1/2", recommended for wheelchairs and walkers. We didn't address the door track. Although it looked weird and encroached on the room, it did the job and actually reduced tripping.
