July 21, 20205 yr comment_17565 My client has a double fd60 door set with a 25mm gap under the doors and frame (the frame has timber between it and the ground both sides), presumably face fix smoke seals can be added to the doors but what measures would be required for the frame. Is this a replacement frame standing on the ground? Report
