[Four-wheel drive, sunshade with you] The four-wheel base with industrial-grade bearings can be easily pushed, and the garden, pool and terrace can be switched freely. One push and one pull can unlock a new sunshade posture for all scenes [Double brake parking, rock-steady] The patented locking wheel set becomes a fixed counterweight in seconds, and it does not move in the strong wind and scorching sun, so that a 10 ft. umbrella can also dance the "fixed wind dance" elegantly [Wide-area adaptation, intelligent control of space] The 1.5 -1.9 in. umbrella pole intelligent compatibility system, 6 -12 ft. parasols can be flexibly moved, and the courtyard renovation will say goodbye to brute force transportation. Color: Black. Material: Metal.
