This is especially important when a door closer is also installed. EN standards shown in this manual are based on the use of three hinges per door. However, we recommend that four hinges are used on doors over 2,250mm in height. Door stop Number of hinges Additional information Standard doors Three hinges to be fitted This gives the most effective load bearing capability Heavy doors Four hinges to be fitted Recommendation based on load bearing as the prime consideration Tall doors (over 2,250mm) Four hinges to be fitted (equally spaced) For tall doors, or those which are particularly subject to warping such as glazed doors Doors with door closers Three hinges – two at the top and one at the bottom for improved load bearing For some fire doors (heavier construction or with a hold open door closing device) it is best practice to fit two hinges at the top of the door with the third hinge at the bottom of the door. Hinges should be positioned as follows: C entre line of the top hinge 250mm from the top edge of the door. C entre line of the third hinge is 200mm from the centre line of the top hinge. C entre line of the bottom hinge 250mm from the bottom edge of the door. Equidistant spacing 250mm 250mm Hinges in pairs, fitted high and low on the door 250mm 200mm 200mm 250mm Additional support for top hinge 250mm 200mm 250mm Heavy doors For doors heavier than the recommended door mass, it may be possible to install two hinges high and two hinges low for improved load bearing capacity. Doors over 2100mm high It is possible to use four hinges equally spaced to give maximum resistance to warping.
