If you are using these on a fire door, to fully comply with BS EN 1634 test requirements you will need to add 'Intumescent Pads' behind the hinge leaves to continue the protection along the perimiter of the door, the hinge pad rapidly expands to provide additional protection in the hinge area, insulating the heat transfer from hinge to the door and helping to maintain the door integrity. Coastal do not supply these pads but you can obtain them from this link if you so wish.
Please note, we do not recommend these hinges to be used externally or on acidic timbers!
