Automatic Door Seal Keeps Drafts Out
"A 114 in. gap under your frontt door is like having a 9' in. hole in your wall," says Ray Syverson, president of Keystone Industries, Elkader, Iowa. To keep costly drafts out, and heat in, Keystone Industries has developed a unique automatic door seal.
When the door is closed, the seal is held tightly against the floor. When the door is opened, the seal springs back away from the floor with no dragging or sweeping of the floor.
The new "energy saver" attaches to storm doors, patio doors, indoor doors or even garage doors.
Keystone makes the seals for right or left hand doors, from 2 ft. to 5 ft.. wide. If the door swings in, the seal is fastened on the outside of it. If it swings out, the seal is mounted on the inside.
A 36 in. model for regular doors sells for $14.52. Any of the seals can be cut off on one end with a hack saw to fit most any door.
Keystone offers another automatic seal for garage doors that operates on the same principal. It's mounted on each side of a garage door frame. While the door is being lowered, the seal is out of the way. Just before the door reaches the floor, it hits the seal's closing "foot" and the seal automatically snaps shut. When the door is raised, the seal pulls back automatically, same as on the swinging door model.
Garage door seals are just like the swinging door seals except that they are 7 ft. long, Syverson points out. "There is only one spring in them, yet there is equal pressure from top to bottom. And there's nothing that will wear out except the rubber seal, and that can be easily replaced."
A pair of two 7 ft. automatic garage door seals sells for $45.75. Keystone makes them up to 20 ft. long.
