I don't see any thing in your web sight that looks like this It simply slides in a grove at the bottom of the door . This is a metal door between the garage in the house. The track at the slides into is actually the metal skin on the door that has bent under the door.
Any help would be greatly appreciated thanks

Thanks for writing in. We don't have this exact door sweep; but check out our 58-176. This sweep wraps around the bottom of the door and is then installed with screws. Let me know what you think.
