This product is a heavy duty stainless steel butt hinge engineered for flat-opening door applications where strength, alignment, and repeatable swing performance are required. With a 99 mm overall leaf width and a Ø25 mm barrel, it is designed to support stable door rotation on commercial and project-grade installations.
The hinge body features a robust knuckle structure with precision-machined mating surfaces to keep the pivot smooth under frequent cycles. Multi-hole leaves allow flexible fastening on metal or timber door frames, while the defined hole layout helps fabricators match drilling templates and improve assembly consistency.
Two height options are available in the same configuration: 5 inch (152 mm) and 6 inch (171 mm). This makes it easy for OEM buyers and contractors to standardize the hinge platform while selecting the right size for different door heights and weight classes.
