Reinforce and thicken the base: We not only increased the thickness of the base from 2.5 mm to 4.1 mm, but also added four reinforcing triangles to make our outdoor deck umbrella stand more indestructible even in hurricane weather. High-quality material: the screws are made of high-quality metal, which completely avoids the embarrassment of rust of the screws, and the base bracket of the courtyard umbrella will not rust outdoors. Stability module: We specially added a module for fixing the bottom of the umbrella handle, and added another pipe sleeve to make the outdoor umbrella more stable and will not shake even in windy weather. The diameters of the three sleeves are 1.25 inches, 1.5 inches and 1.9 inches respectively. Unique design: the hollow bottom is easy to cause the umbrella handle to rot or rust, especially on the wet ground. Therefore, we sealed the bottom of the outdoor umbrella stand. Wide compatibility: this table umbrella base can be used with beach umbrella, traditional courtyard umbrella or huge courtyard umbrella. The color is black, which can complement all your outdoor furniture and leave more space for your deck or terrace.<br><br>Colour:Black Material:Metal, wood<br><br>Package Contents: 1 * Umbrella holder (with installation accessories)<br><br>Only the above package content, other products are not included.
