A straightener is a hardware component used to straighten door panels, prevent deformation, or correct panels that have already deformed. It is mainly made of aluminum, with carbon steel rods offering stronger straightening force.

It utilizes the inherent elasticity of the metal to generate a force opposite to the bending of the cabinet door. Simply put, if the door panel bends inward, the straightener bends outward to counter the deformation, and vice versa.

An installation is required if the cabinet door height exceeds 1.8 meters, especially for doors made of particle board, European pine board, or density board. It helps slow down deformation and extends the door's service life.

For optimal results, do not install it in the middle. It is best installed on the side near the door handle, positioned at 1/3 of the cabinet door width.

No, a straightener is designed to solve and prevent upper and lower vertical deformation. It cannot correct diagonal deformation of the door panel.

The door panel straightener is made of aluminum profile and iron. It is available in Gold, Black, and Iron Grey colors, and is packaged in quantities of 30pcs.
