Notes  

• Please check the size carefully before ordering.
• When drilling holes with an electric hammer, the screws are easily loosened due to too much vibration, so you can remove the center positioning drill bit after positioning and continue drilling.
• Please note that this product is not suitable for drilling holes in metal, glass, wood, and ceramic tiles.
• If there are tiles on one side of the wall, you need to first use a tile hole opener (not included) to make a hole in the tiles before using this product.
• Please use a hammer drill, not an electric drill. Please note that our package does not include an electric hammer.
• Please allow the slight color difference caused by the shooting light and 1-3cm error due to manual measurement, and make sure you do not mind before you order.
