The concealed built-in rebounder is a device installed on the cabinet door, which is used to generate a certain rebound force when the cabinet door is closed, thereby ensuring that the cabinet door can be fully closed and kept tight. This type of rebounder is usually installed on the inside of the cabinet door, hence the name "concealed". They can help the cabinet door generate a certain amount of elasticity when it is closed, thus preventing the door from not closing completely or from popping open after closing. This design is small, takes up no space, is beautiful and elegant, and helps keep the cabinets tidy and safe. Choosing the right rebounder requires considering the weight, size and environment of the cabinet door to ensure it can provide the appropriate closing force and control speed.

The basic working principle of the built-in cabinet door rebounder is suitable for cabinet doors within 2.5 meters. Use a tool to drill a round hole with a diameter of 10mm and a depth of more than 70mm on the partition board of the cabinet, and then insert the rebounder into it. Add appropriate amount of glue for final fixation. Install a positioning iron piece on the cabinet door and fix it with screws or 3M glue. The iron piece adjusts the length of the bullet to achieve better use.

For the best effect of the straightener, do not install it in the middle, as the hinge can play a part of preventing the deformation of the door panel. The straightener can only solve the problem of preventing upper and lower deformation, but cannot solve diagonal deformation. Usually, the straightener is installed on the side near the handle of the door, and 1/3 of the cabinet door is the best position.
