Fitting Hinges
It is essential when fitting door hinges that the door frame is vertically and horizontally plumb, especially the hinge side as the pivot point of all hinges requires to be the same for correct operation. Misalignment can cause the integrity of the hinge and any other hardware components to become compromised, leading to the breakdown of the doorset operation. Always refer to manufactures installation instructions for any special requirements.
If intumescent pads are being fitted behind the hinge leaf for fire regulations, ensure to increase the mortice depth accordingly.
