Hello, Please confirm 385 is the correct channel. Does the strength stamp shown in photo mean 2640? Thank you for your help.

Thanks for posting. Yes, well done: this looks like an S385-27 with a stamp option of 2640. You just may want to confirm the metal channel, not including the end attachments, is 27" just to be safe.
