This accessory has a basic square shape, yet it boasts an adjustable width ranging from 260mm to 400mm. To enhance its lateral strength, a unique design features sliding contact between all four sides. This linkage ensures that the sides remain in constant contact with each other. For easy extension, simply pull on one or two of the corners; the accessory will not extend on its own due to the specifically designed bottom elements.
