This is a slip-resistant slope (ramp) used indoors to prevent tripping and to eliminate level differences for wheelchairs. Both ends are sloped to prevent catching feet. The underside is grooved to allow for running wiring and cords. I purchased this at a home center and used it for about six months in a room before moving. I removed it after attaching it with double-sided tape (see photo 4), so there is no adhesive left. However, it should be usable again if you replace the double-sided tape. I used it in a wheelchair-free indoor environment, so there are no noticeable scratches or stains.
