It uses a rack and pinion mechanism with hydraulic valve control to regulate door swing speed and backcheck. The unit is designed for commercial door applications where controlled closing speed and hold-open positioning are required. Licensed door hardware technicians and commercial contractors typically specify and install this closer. Key attributes include adjustable closing and latching speed, valve-controlled backcheck, and an aluminum alloy body construction.\u003c\/p\u003e\n\u003cp\u003eThis closer is suited for commercial and institutional applications where surface mounting is required and hold-open capability is a code or operational requirement. The full cover assembly protects the internal mechanism from dust and tampering. The dark bronze finish integrates with common commercial door hardware finishes. Installation is performed at the door head on either the push or pull side depending on the arm configuration selected.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAdjustable hold-open arm allows the door to stay open at a set position\u003c\/li\u003e\n  \u003cli\u003eFull cover protects the closer body and mechanism from environmental exposure and tampering\u003c\/li\u003e\n  \u003cli\u003eRack and pinion hydraulic mechanism with valve-controlled backcheck\u003c\/li\u003e\n  \u003cli\u003eAdjustable closing speed and latching speed via independent valves\u003c\/li\u003e\n  \u003cli\u003eAluminum alloy body construction for durability and reduced weight\u003c\/li\u003e\n  \u003cli\u003eDark bronze finish compatible with standard commercial door hardware sets\u003c\/li\u003e\n  \u003cli\u003eSex nut fasteners included for through-bolt door mounting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style surface mount door closer for commercial hollow metal and wood door applications requiring adjustable hold-open and full cover trim.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed door hardware technician or commercial contractor. Before mounting, verify door weight, width, and applicable fire-rating requirements, as closer size selection must comply with ANSI and local building codes. Power is not required for this mechanical closer, but all hydraulic speed adjustments should be made with the door in operation using a flat-blade screwdriver on the valve screws. Do not over-tighten valve adjustments, as doing so can damage internal seals.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 15.35 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 6.22 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 3.78 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 7.7 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Dark Bronze\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Type\u003c\/strong\u003e: Surface Mount\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: 8501H690\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51557500092722,"sku":"8501H690","price":232.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2fd41a6352e0a93a47f06170569f4015.jpg?v=1786389561","url":"https:\/\/voomisupply.com\/products\/norton-closers-8501h690-surface-mount-door-closer","provider":"Voomi Supply","version":"1.0","type":"link"}
