delboy Posted December 10, 2021 Report Share Posted December 10, 2021 Have a FD30 Fire Door, from 1990. Door has been upgraded with Overhead Closer and new Fire rated hinges. Originally he door had a perko chain. Can I leave that in place? Or is it required that it is removed? If it needs to be removed what would I use to fill the hole left in the door? Would a Fire Stop putty be OK, and painted ? Quote Link to comment Share on other sites More sharing options...
Tom Sutton Posted December 11, 2021 Report Share Posted December 11, 2021 If the perko is still working then it could interfere with the working of the overhead closer so I would remove it and fill with hardwood/ fire stop putty. Quote Link to comment Share on other sites More sharing options...
