Fire stop safety astragal |
摘要 |
An astragal is formed by securing lengthwise flexible fire-resistant material to a mounting channel adapted to be mounted on an elevator fire door. The flexible fire-resistant material of the astragal is secured to the upwardly extending flanges of the mounting channel to form an elongated boot of uniform cross-section, wherein the astragal nose is substantially parallel to the mounting channel thereby insuring an effective fire seal.
