A perfect accessory that provides better movement for your light stand is the Kupo Caster with Brake 100mm/ 30mm Square Adapter Set of 3. This caster is a perfect for using in studio where smooth and soundless operation is most required. It also helps in repositioning the lighting fixtures, while also protecting the floors from getting scratched. This caster comes as a set of three casters of 3-15/16 inches or 100mm in size that is designed to fit 1-3/16 inches or 30mm square legs. The brakes on the casters help in preventing the movement of the wheels and keep your stand locked in place.
