Using this Compact Mini Harp Rack is easy. First, assemble it as it comes knocked down. Once it's set up, place the glass pieces on the rods. The adjustable rod spacing allows you to fit different glass sizes. You can slide the glass easily on the low - friction floor. When you need to move it around, use the 4 non - marking swivel casters. Lock it in place with the two - foot locks for stability. For maintenance, keep the rack clean. Wipe it regularly to prevent dust and debris from building up. Check the casters and foot locks periodically to make sure they're working properly. If you notice any damage to the plastic - covered rods, replace them as needed. Also, avoid overloading the rack beyond its capacity of 29 glass pieces and the weight limit of the casters (1000 lbs each).
