Single and Double Action Spring hinges to give them there full name do exactly what they say; a single action hinge will close a door which opens in one direction and a double action hinge will close a door which opens in both directions. The classic use for double action hinges is in a restaurant on the kitchen two way door.
Fire Door Situations
In fire door situations the hinges used must be appropriately approved. If you have any doubts please contact customer services and we can advise on the correct hinges to use. Whilst the automatic closing of domestic fire doors has been relaxed of the past few years, hinges used on fire doors must be CE marked and approved for use.
