Because this is an in-house brand, we use only premium materials that won't crack or shatter. Enjoy the lowest prices on threshold replacement kits for your garage doors. Our storm shield garage door threshold kits meet California Fire Marshall and CPAI-84 requirements for flame resistance. Our crack-resistant rubber threshold weather strips are backed by a two-year warranty. Because they're sold by the foot, order only what you need for your garage door threshold. We recommend that you order a slightly longer piece of our black weather sealant to assure that you have enough during installation. Instruction manuals are included with our shatter-resistant NSCD garage door threshold seals. These sturdy seals will remain flexible in temperatures as cold as minus-40 degrees Fahrenheit and temperatures as hot as 150 degrees Fahrenheit.
