It features a spring-loaded Cush-N-Stop arm that cushions the door at the end of its swing, reducing impact stress on the door frame and hardware. Configured for push-side parallel arm mounting, it delivers a 110-degree maximum swing arc and is adjustable from Size 1 through Size 5 to accommodate a range of door weights and widths. A full plastic cover protects the closer body, and the aluminum painted finish suits standard commercial door frames. Installation is performed by qualified door hardware or general contractors.\u003c\/p\u003e\n\u003cp\u003eThis closer is suited for commercial entryways, office corridors, institutional facilities, and other high-traffic door openings where controlled closing speed and stop-arm cushioning are required. The push-side parallel arm configuration is commonly used where overhead clearance is limited or where the closer body must be mounted on the push side of the door. The right-hand designation applies to doors with the hinge on the left when viewed from the push side. Size adjustability from 1 to 5 allows a single unit to serve a wide range of door sizes without replacing the closer body.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n \u003cli\u003eGrade 1 commercial duty rating for high-cycle, high-traffic applications\u003c\/li\u003e\n \u003cli\u003eSpring Cush-N-Stop arm cushions door at end of swing to protect frame and hardware\u003c\/li\u003e\n \u003cli\u003ePush-side parallel arm mounting for installations with overhead clearance constraints\u003c\/li\u003e\n \u003cli\u003e110-degree swing arc for wide door opening travel\u003c\/li\u003e\n \u003cli\u003eSize 1 to 5 spring power adjustment accommodates varying door weights and widths\u003c\/li\u003e\n \u003cli\u003eFull plastic cover protects closer mechanism from dust and damage\u003c\/li\u003e\n \u003cli\u003eAluminum painted finish in 689 designation for a clean, neutral appearance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style surface door closer for commercial-grade door assemblies requiring push-side parallel arm mounting with a right-hand swing configuration.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed door hardware technician or commercial contractor following the manufacturer template and ANSI A156.4 standards for door closers. Secure the door in the open position and verify frame construction before drilling mounting holes. Follow the provided arm geometry template precisely, as incorrect arm positioning will affect closing force and door alignment. Adjust spring power only within the Size 1 to 5 range marked on the closer body.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Grade 1\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eArm Type\u003c\/strong\u003e: Spring Cush-N-Stop\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eMounting Type\u003c\/strong\u003e: Push Side Parallel Arm\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eSwing Arc\u003c\/strong\u003e: 110 degrees\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eSize Range\u003c\/strong\u003e: 1 to 5 (adjustable)\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eCover\u003c\/strong\u003e: Full Plastic Cover\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Aluminum Painted (689)\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eHand\u003c\/strong\u003e: Right-Handed\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: LCN\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4111-SCUSH RH 689\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LCN","offers":[{"title":"Default Title","offer_id":68299470700850,"sku":"4111-SCUSH RH 689","price":572.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8f7520384d8d0400cb02b47af43c8719_9aecdf6a-3e0a-42ea-bb86-29ef41b9cb5d.jpg?v=1793714928","url":"https:\/\/voomisupply.com\/products\/lcn-4111-scush-rh-689-surface-door-closer-right-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
