This is a channel marked 1420, 15 inches long, 1/2 inch wide. I need 2 replacement parts. Can you please identify the correct replacement part?

Hello,

We'd be happy to help but we would need to see a photo of the attachment at the opposite end of the metal channel as well to narrow down your replacement options. Thank you!
