This soft-close hinge is specially designed for heavy lids, making it an ideal safety accessory for items like toy boxes and storage chests. Featuring a hydraulic support structure, it keeps the lid stable when open and allows for slow, gentle closing, effectively preventing finger pinching and ensuring high safety. With strong load-bearing capacity, 2-hinges combined can hold up to 45 lbs. while a single 1-can bear 22 lbs. It supports adjustable opening angles from 75° to 105°, offering flexible use. The installation is versatile, fitting both left and right sides, and compatible with side-mounted and top-mounted setups, adapting to various scenarios. Made of sturdy and durable materials with a stable structure, it is widely suitable for toy boxes, benches, storage chests, pet house roofs, and other items requiring heavy lid support. Note that this hinge is not suitable for small or light cabinet doors; for lighter lids, a single hinge is sufficient.
