It uses a rack and pinion hydraulic mechanism with valve-controlled adjustments to regulate closing speed and backcheck. The body is constructed from aluminum alloy, keeping the unit lightweight while maintaining structural integrity. This closer is installed by door hardware specialists or commercial contractors on standard swinging doors in commercial and light commercial applications where hold open functionality is required.\u003c\/p\u003e\u003cp\u003eThe 1601H689 is suited for interior and light commercial doors in facilities where traffic volume calls for a medium duty closer. The adjustable hold open arm allows the door to remain open at a set position, which is useful in warehouses, offices, schools, and healthcare settings. The sex nut fasteners are included for installations where through-bolt mounting is required rather than traditional wood or machine screw attachment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAdjustable hold open arm holds door at a set position without additional hardware\u003c\/li\u003e\n\u003cli\u003eRack and pinion hydraulic mechanism with valve-controlled closing speed adjustment\u003c\/li\u003e\n\u003cli\u003eValve-controlled backcheck prevents door from slamming against the stop\u003c\/li\u003e\n\u003cli\u003eAluminum alloy body construction reduces unit weight while maintaining durability\u003c\/li\u003e\n\u003cli\u003eIncludes sex nuts for through-bolt mounting applications\u003c\/li\u003e\n\u003cli\u003eSurface mounted design for straightforward installation without mortising\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new installation unit for medium duty commercial surface mounted door closer applications on standard swinging door frames.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSurface mounted door closers of this type are typically installed by commercial door hardware technicians or general contractors following ANSI A156.4 standards. Shut off any access control or electric hold open systems connected to the door before beginning installation. Ensure the door frame and header are structurally sound and capable of supporting the closer and arm assembly. Follow the manufacturer template for hole placement and verify arm geometry matches the swing direction before final fastening.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eFinish\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 12.3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 5.1 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: 7.9 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Included\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\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: 1601H689\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51558740754738,"sku":"1601H689","price":166.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/986495e68a61696882ba33f85cc5fa0e.jpg?v=1786419333","url":"https:\/\/voomisupply.com\/products\/norton-closers-1601h689-surface-mounted-door-closer","provider":"Voomi Supply","version":"1.0","type":"link"}
