The UNi-PRO Heavy Duty Paint Roller Tray, suitable for use with 230mm rollers features deep paint grooves to add rigidity and allow for even more paint loading. Suitable for all paints, the paint well allows for maximum paint pick-up, while its heavy duty plastic construction makes it long lasting. Handy Tip: To help make cleaning quicker and easier use a disposable tray liner. This allows you to keep your original tray and just replace the liner after each coat.
