When ordering weatherstripping for steel rolling doors from DDM Garage Doors, keep in mind the distinction between two products.

One is Steel Rolling Door Clip-on Guide Seal, product SS-SRD10. As the name implies, this is a seal product, and does not require an insert; it clips on to complete the seal process. The other is SS-SRDC10 (pictured below with 2″ vinyl insert). This is a clip-on product also, but it is called Steel Rolling Door Clip-on Guide Retainer. As a retainer, it holds standard vinyl/rubber inserts or standard brush seal inserts. Even though the numbers of these Steel Rolling Door weatherstripping products are similar, their uses are different.
