Gravity Hinge
The Gravity Hinge from Bolton Industries is a self-closing door hardware device constructed from Stainless Steel 304 or Carbon Steel with Zinc Plating. It operates via spring tension or hydraulic pressure to automatically return doors to a closed position, ensuring consistent fire safety compliance and improved energy efficiency in high-traffic environments. This model is engineered for commercial kitchens, restaurants, fire-rated doors, and industrial gates where reliable closure is critical.
Available in finishes suited for both interior and exterior applications, these hinges meet architectural and door hardware standards for durability and corrosion resistance. Stainless Steel 304 offers superior resistance to rust and pitting, while the zinc-plated Carbon Steel variant provides cost-effective protection in less corrosive settings. Typical industry specifications for such hinges include load-bearing capacities of 20 kg to 80 kg per pair, with standard opening angles of 90 or 180 degrees depending on the application.
Primary buyers include facility managers, contractors, and distributors sourcing for projects requiring fire-rated or high-usage door systems. These hinges are exported globally under architectural hardware categories, with common packaging in bulk cartons of 50 to 100 units. Confirm lead times and Incoterms with Bolton Industries, as these are not specified in the listing. The product’s self-closing mechanism is particularly valued in environments where doors must remain shut to maintain safety or climate control.
