Architectural Hinges are designed to provide an effective solution to hanging doors where there is a need for high grade architectural quality hinges. The obvious requirement of a hinge is to attach a door or window to a frame. What is often over-looked is that a hinge must carry the weight of the door without sagging. Hinges are often under-specified due to lack of understanding or to save money and people just accept that doors are supposed to sag, or bind or drag. Hinges should allow the door to swing easily and with minimum friction.
