A metal core adds strength and stability, making this trim more durable than other high-temperature rubber trim. It withstands temperatures up to 400° F, which is generally twice as high as our standard rubber trim. Use it to protect the edges of panels, boards, and signs from impact. Made of rubber, it resists abrasion better than plastic trim.
