Spring bronze door kit for sealing one door
When you just need enough spring bronze to seal up one door, this is the kit. It has what it takes to air-seal a typical door, which runs about 3 feet by 7 feet.
Spring bronze is the traditional weatherstrip for old doors. It tucks into the jamb and the springy bronze closes the gap when the door shuts. Where the lock gets in the way, the included lockstrip handles that spot, since regular spring bronze can’t run right next to the lock.
What’s in the kit
- 20 ft of 1″ x 1/4″ wide spring bronze
- 1 box of nails
- 1 ft of bronze lockstrip
- Your choice of bronze nails or copper-plated nails
For a larger door, order more than one kit. If you have several doors, a full 100 ft roll of spring bronze may be the better buy.
