Product Features: 2 Hinges - Dimensions: 380 mm long, 165 mm high when open. Multifunctional + Space-Saving: The lift hinge can be used as a replacement accessory for a liftable coffee table, or it can transform a traditional coffee table into a multifunctional one. When extended, it can serve as a dining table or desk for eating, reading, and working. Premium Material: The folding table mechanism is made of high-quality iron, offering strong load-bearing capacity. It's not easily bent or broken when folding, ensuring strength and durability. A rust-proof coating is added to the surface to prevent rust and ensure longevity. Easy Installation: Coffee table hinges are very simple to install. Just choose the appropriate thickness of the hinges and attach them to the coffee table surface and the inside of the coffee table to create a multifunctional coffee table. (Please note that screws are not included; the length of the selected screws should be less than the thickness of the coffee table surface). Easy to Use: The coffee table hinges are supported by highly elastic springs at the hinge fold, providing a certain damping function. When opening, lift the coffee table top with both hands. When closing, press the panel with both hands. Please note that one-handed operation is not recommended.
