Refrigerator sliders make it easy to move the fridge around on the floor without causing any damage to the tile or linoleum below. The sliders go on the bottom of the fridge, and their design lets them slide smoothly rather than scraping the floor.
Moving a refrigerator or other appliances can be necessary to clean behind and beneath the unit. Sliding the refrigerator away from the wall gives the owner access to clean the coils, which can attract the sort of dust that hinders refrigeration. As long as the sliders stay beneath the refrigerator, and as soon as the cleaning or other maintenance is finished, the owner can slide it right back into its usual location.
