These hinges have the strength to support heavy security door leaves and have the durability to withstand a lifetime of constant use.

The hinge design with liner bearings within and thrust bearings between each knuckle provides ease of use, durability and maintenance free operation.

Each hinge is welded top and bottom to provide a strong tamper-resistant construction and fitted with a stainless steel centre pin, sealed within the body of the hinge.
