The product is the invention of a device-application on wheels that is connected to a standard paint tray, tubs and containers. When the device is connected to the paint tray it is possible to mobilize a paint tray on wheels. The devices with the wheels are connected to the upper ledge of the tray or tubs or containers. The devices make it possible for the paint tray to be mobile or stationary. When in a stationary position, the tray stops by the lower frontal part of the tray itself, and the backside of the tray stays standing on wheels and this causes a halt and an inability to move. When in a mobile position, by pressing the holder of the roller or on the deep backside of the tray by the roller, the frontal part of the tray rises and transfers its weight to all the wheels and thus allows a mobile position. The moveable tray is permissible because the connection of the device to the backside ledge is low in comparison to the other devices. The former lower backside device can be activated with a spring or without a spring. |
