Easy-Rolls are light or reflector hangers, that allow you to easily adjust the height of your light or reflector as the plant grows. These are sold as a set of two.
Each easy roll is able to hold 5Kg, so with 2 Easy-Rolls it’s also possible to hold lamps up to 10kg.
Easy-Rolls uses a calibrating function to establish the light/reflector. You just need to calibrate it the first time you use the light/reflector. There is no need to adjust each time thereafter.
