Questions
Question about the product
Spencer Marshall on 2024-07-31 10:44:32 | Question:
With regards to the Astro drop down seals we have an 18mm gap to the bottom of the door so can we simply instal the drop down seal 4-5mm down the door so reducing the gap to 14mm which is the maximum for this product |
Answer from Rawlins’ Technical Team:
No, we would advise against this as the installation instructions advise to fit the seal flush with the bottom of the door. If the seal drops below this, a pivot point will appear on the bottom of the door and any extra leverage caused by this could cause the seal to rip from the door when opening/closing, or too much friction on the floor. | |
Ash on 2024-03-25 17:14:09 | Question:
Can this be used as an extension on a fire door? I have a gap at the bottom of the door and need a product which is fire proof rated to support the regulations. |
Answer from Rawlins’ Technical Team:
The drop down seal only has 14mm of movement, please contact [email protected] with further information so we can assist. | |
