This door hinge is a CE grade 13 ball bearing type with a max load of 120kg (per 3 hinges). The most popular type of door hinges on the market today. They have a CE mark and are certified tested. Suitable for commercial and domestic use. Made from solid stainless steel and finished in on-trend finishes to match your home. Ball-bearing hinges have always been very popular for their smooth operation, durability, long-lasting design, and ability to carry heavier loads than washed hinges. For standard internal residential doors a pair of hinges is adequate; however, fitting 3 hinges per door has its advantages. It will look aesthetically pleasing and from a practical viewpoint, it helps spread the load evenly and will help to overcome twisting or warping. It is fire door rated.
