Replace the worn or cracked weather seal on your 17-ft. wide CLO-400 Clopay residential steel garage door with this 18-ft. long Clopay weather seal from Garage Door Supply Company. This O-shaped weather seal is uniquely designed for single-channel Clopay garage doors. It arrives flat. When folded, and the L-shaped legs are installed on the Clopay garage door bottom retainer, the result is a 1 1/4-in. bulb that creates a weatherproof seal, accommodating even garage floors that are uneven.
By sealing out winter and summer drafts, storm water runoff, pests and dust, you'll save money on energy bills and also prevent costly damage to the contents of your garage. The black seal is made of EPDM synthetic rubber that will stand up to below-freezing temperatures and heat as high as 350 degrees Fahrenheit. Always make sure the weather seal you order is 1 ft. longer than the width of your garage door to account for any shrinkage and to accommodate the cutting-to-fit process.
