Consealed fire door drop down seal  M-type spring structure, suitable for doors with slots in the door leaf. During installation, there is a 34mm*14mm through slot at the bottom of the door. Place the product in it, fix it from the wing of the product, and install the decorative end cover with screws. The use of this product does not affect the overall style of the door.
