I bought this to attach items that I want to keep mobile if I need to move them. They're easy to install and remember to plan where you want BOTH rest sets so you don't have to start over with both sets.
Pros
QUIET AND STABLE β High-quality ball bearings and rubber materials absorb shock and vibration. The 3-inch casters are very quiet and stable when moving, leaving no marks on the floor, which is very convenient and practical.
