Hager 1150 4-1/2" x 4-1/2" Stainless Steel Single Acting Spring Hinge
The Hager 1150 is a premium stainless steel self-closing hinge designed for automatic door closure in demanding environments. Manufactured from high-grade stainless steel with matching stainless steel internal components, this hinge is the ideal solution for coastal areas, medical facilities, laboratories, and food processing plants where corrosion resistance is paramount. As a single acting spring hinge, it provides the reliable closing force required to meet strict building codes while maintaining a clean, professional aesthetic.
Compliance, Fire Safety, and NFPA 80 Standards
Meeting life-safety codes is critical for commercial openings. The Hager 1150 meets ANSI K51071F standards and is approved for use on labeled fire doors in hotels, motels, and institutional buildings. Per NFPA 80 regulations, self-closing hinges ensure that fire doors return to a latched position to maintain the integrity of fire barriers. These hinges are approved for use on 4' x 8' labeled doors when a minimum of three spring hinges are installed, ensuring your facility remains compliant and secure.
Heavy-Duty Corrosion Resistance
Unlike standard steel spring hinges, the Hager 1150 is built entirely from non-ferrous stainless steel. This ensures that the internal spring mechanism and the hinge leaves remain functional and rust-free even in high-moisture or salt-air environments. It is specifically designed for 1-3/4" thick doors and provides a maintenance-free alternative to surface-mounted door closers.
