This is a reinforcing material made of full carbon. It is expected to be used in a variety of applications, including reinforcing the inside of doors, reinforcing under panels, reinforcing hanging parts and trunks, and preventing chattering noise in lightweight parts. When installing to an external door made by another company, please make a hat-shaped notch at the rear of the door and insert it. Adhesive mounting using panel bonding is preferable because it creates rigidity on the surface, but fixing with bolts and nuts or rivets also provides strength. The weight is 280g. The adhesive part on the back is attached at the time of shipment. Please process it according to your usage.
