Built with an aluminum alloy body, it features an adjustable hold-open function that keeps doors open at a set position until manually released. The rack and pinion mechanism delivers consistent closing force across the full arc of door travel. Valve-controlled backcheck absorbs impact when the door is opened forcefully, protecting both the closer and the door frame. The aluminum finish suits standard commercial hardware schedules. This unit is sold individually and is installed by licensed door hardware technicians or commercial contractors.\u003c\/p\u003e\u003cp\u003eThe 7500H689 is suited for heavy duty commercial doors in high-traffic environments such as office buildings, schools, healthcare facilities, and institutional buildings. The adjustable hold-open feature is commonly used in corridors and storage areas where doors need to remain open during active use. The surface mount design allows installation on the push or pull face of the door without requiring a concealed pocket, simplifying retrofit and new construction installs alike. Sex nuts are included for through-bolt mounting applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAdjustable hold-open function keeps door at a fixed open position\u003c\/li\u003e\n\u003cli\u003eRack and pinion closer mechanism for consistent, reliable operation\u003c\/li\u003e\n\u003cli\u003eValve-controlled backcheck protects door and frame from impact damage\u003c\/li\u003e\n\u003cli\u003eAluminum alloy body construction for durability and corrosion resistance\u003c\/li\u003e\n\u003cli\u003eSurface mount design suits both new construction and retrofit applications\u003c\/li\u003e\n\u003cli\u003eSex nuts included for through-bolt mounting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style heavy duty surface mount door closer for commercial door applications where an adjustable hold-open function and aluminum finish are specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a licensed door hardware technician or commercial contractor familiar with surface mount closer applications. Disconnect or isolate any electric strike or access control hardware before beginning work.
