Built around a rack and pinion mechanism with hydraulic valve control, this closer delivers consistent sweep and latch speed across a wide range of door weights and traffic levels. The adjustable backcheck feature helps protect the door and frame from impact damage during hard openings. Licensed contractors and door hardware installers specify this closer for commercial and institutional applications where durability and repeatable performance are required.\u003c\/p\u003e\u003cp\u003eThis closer is intended for surface mount installation on heavy duty commercial doors. The aluminum finish suits interior and light exterior applications where a clean, low-profile appearance is expected. The included sex nuts allow for solid, pull-through mounting into hollow metal and wood doors without the need for through-bolts. Adjustable sweep, latch, and backcheck valves let the installer dial in closing performance to match door weight, frequency of use, and code compliance requirements.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRack and pinion hydraulic mechanism with valve-controlled backcheck\u003c\/li\u003e\n\u003cli\u003eAdjustable sweep speed, latch speed, and backcheck for field tuning\u003c\/li\u003e\n\u003cli\u003eSurface mount design with sex nuts included for secure door attachment\u003c\/li\u003e\n\u003cli\u003eAluminum finish body suited for commercial door applications\u003c\/li\u003e\n\u003cli\u003eHeavy duty construction rated for high-traffic installations\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 hollow metal and wood door assemblies requiring adjustable hydraulic closing control.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a licensed door hardware technician or commercial general contractor. Shut the door and secure it open before drilling or fastening to prevent movement during layout. Follow ANSI and local building code requirements for closer placement and required closing force on accessible routes covered under ADA guidelines. Do not over-tighten the valve adjustment screws, as doing so can damage internal seals and void the closer warranty.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Type\u003c\/strong\u003e: Surface Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Type\u003c\/strong\u003e: Sex Nuts Included\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 15.2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 6.3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 3.8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 9.4 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSales Unit\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: NORTON CLOSERS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7500689\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51560392818994,"sku":"7500689","price":401.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/02cc226c15191c74967de4adae075d02.jpg?v=1786452082","url":"https:\/\/voomisupply.com\/products\/norton-closers-7500689-heavy-duty-surface-mount-door-closer","provider":"Voomi Supply","version":"1.0","type":"link"}
