It uses a rack and pinion mechanism with hydraulic valve controls to regulate door swing speed, backcheck, and latch action. Sex nuts are included for straightforward mounting to door and frame assemblies. At 12.1 inches long, 5 inches wide, and 3.7 inches tall, it fits standard commercial and light commercial door openings without requiring specialty hardware. Licensed door hardware technicians and commercial contractors are the typical installers for this type of unit.\u003c\/p\u003e\n\u003cp\u003eThis closer is suited for medium-duty applications in commercial and institutional settings where consistent, controlled door closing is required. Typical installations include office entry doors, corridor doors, and light-traffic access points. The adjustable valve design allows the technician to fine-tune closing speed and backcheck force on-site to match door weight and traffic patterns. The aluminum finish blends with standard commercial door hardware and resists corrosion in interior environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRack and pinion hydraulic mechanism for smooth, consistent door control\u003c\/li\u003e\n  \u003cli\u003eAdjustable closing speed and backcheck via on-body valves\u003c\/li\u003e\n  \u003cli\u003eSex nuts included for secure surface mounting to door or frame\u003c\/li\u003e\n  \u003cli\u003eMedium-duty rating suitable for standard commercial traffic levels\u003c\/li\u003e\n  \u003cli\u003eAluminum finish for corrosion resistance in interior applications\u003c\/li\u003e\n  \u003cli\u003eCompact body at 12.1 x 5 x 3.7 inches for broad door compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation surface mounted door closer for medium-duty commercial door applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed door hardware technician or commercial contractor. Ensure the door is held open or secured before mounting to prevent movement during installation. Follow ANSI A156.4 standards for door closer installation and adjust valves only with the door in the fully closed position to set accurate closing force. Do not over-tighten the sex nuts, as this can distort the mounting plate and affect closer alignment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuty Rating\u003c\/strong\u003e: Medium Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Type\u003c\/strong\u003e: Surface Mounted\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 12.1 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 3.7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 6.7 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Sex Nuts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSales Unit\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 1601689\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51558967804210,"sku":"1601689","price":138.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f684fd7c2d9ad5f13d99f15cfcd742b8.jpg?v=1786424345","url":"https:\/\/voomisupply.com\/products\/norton-closers-1601689-surface-mounted-door-closer","provider":"Voomi Supply","version":"1.0","type":"link"}
